[3], S. bongori is classically regarded as the Salmonella of lizards. Salmonella spp.. Salmonella is one the most important species of the Enterobacteriaceae family and this genus is divided into two different species: Salmonella enterica and Salmonella bongori.Salmonella enterica is subdivided into the subspecies enterica, salamae, arizonae, diarizonae, houtenae, and indica. Salmonella bongori, Salmonella enterica and its subspecies - Salmonella enterica subsp arizonae, Salmonella enterica subsp diarizonae, Salmonella enterica subsp ... Characteristics . Salmonellosis, paratyphoid infection: Within this group are included Salmonella serovars associated with foodborne human disease. Salmonellaspp. bongori. The case–fatality rate of human salmonellosis in that year was 0.13%. Salmonella possesses two sets of antigens; a flagellar or H antigen and a heat stable polysaccharide known as the somatic or O antigen. arizonae): Arizonae infection affects avian, mammal, and reptilian species. The source of virulence in all Salmonella entericaserovars that carry pathogenicity is lands 1 and 2 (SPI-1, SPI-2), acquired via a process called horizontal transfer either by plasmids or phages (Bäumler et al., 1998). There are more than 2600 serovars of zoonotic Salmonella and the prevalence of the different serovars changes over time. This was increased in 1995 to 2399 (Popoff et al., 1995). Destro, V.B. should be considered far more common [53]. Nucleotide (GenBank) : AY134484 Salmonella bongori strain ATCC 43975 F-ATPase beta-subunit (atpD) gene, partial cds. bongori. Members of this group are found in a wide range of species (birds, mammals, reptiles, fish, and insects). Microbiologically, Salmonella belong to the flagellated, rod-shaped Enterobacteriaceae family. In human patients with noninvasive salmonellosis, symptoms generally resolve in 5–7 days with supportive therapy [54]. S. dysenteriae is a common pathogen that causes classic bacillary dysentery, in which as few as 10 cells are able to manifest infection in susceptible individuals. Salmonella typhimurium, in a study, showed to contain at least 60 genes that are required for virulence (Groisman and Ochman, 1997) and among those, approximately 42 genes are in the two SPIs. The highest proportions of Salmonella-positive units were reported for fresh broiler meat and fresh turkey meat, at average levels of 4.8% and 9.0%, respectively. Salmonella is a genus of Gram-negative, facultative anaerobe bacillus belonging to the Enterobacteriaceae family, consisting of only two species, Salmonella bongori and Salmonella enterica. The separation of serovars is based on antigenic polymorphisms of lipopolysaccharide (O antigens), flagellar proteins (H antigens), and capsular polysaccharides (Vi antigens). The overall notification rate of human infection due to Salmonella in 2010 was 17.6 per 100 000 population with a case–fatality ratio of 0.4%. Pan-genome characteristics of Salmonella. The Shigella species are of concern among other enteric bacteria as they can grow in a wide range of temperature, as low as 10°C and as high as 48°C (Zaika et al., 1989). It is a Gram-negative bacilli, motile and non-lactose fermenter. Acute cases of infection are related to septicemia. C. Löfström, ... B. Malorny, in Encyclopedia of Food and Health, 2016. S. enterica subspecies are enterica, salamae, arizonae, diarizonae, houtenae, and indica. These epidemiological facts are the main barrier to controlling the spread of this pandemic infection (2004). Serovars isolated from common marmosets have included typhimurium, anatum, seftenberg, newington, oranienburg, and habana [3]. bongori) had evolved significantly from the other six subspecies. Detection of Salmonella was reported from a wide range of foodstuffs, but the majority of data were from various types of meat and meat products. For example, Salmonella enterica subspecies enterica serotype Enteritidis can be referred to simply Salmonella Enteritidis, nomenclature that will be used throughout this chapter. Salmonella Compiled By: Julie A. Albrecht, Ph.D., Associate Professor The Organism: Many species of Salmonella bacteria exist; several cause foodborne illness.Salmonella typhimurium has been the species that accounts for most foodborne illnesses related to this bacteria. In humans, there are three major diseases caused by Salmonella: typhoid fever (caused by Salmonella Typhi and related strains), gastroenteritis (caused by most Salmonella serovars, such as Salmonella Typhimurium and Salmonella enteritidis), and an invasive disease (caused by Salmonella choleraesuis). Salmonella Subgroup I (includes most serotypes): 1. Introduction. ; Symptoms usually begin 6 hours to 6 days after infection and last 4 to 7 days. Clinical signs are usually observed in birds less than 3 weeks of age, which are found dead in shell or die quickly after hatching, due to peritonitis and septicemia (Shivaprasad, 2013b). Ribeiro, in Encyclopedia of Meat Sciences (Second Edition), 2014. M.T. Only a few of these serovars are responsible for most Salmonella infections in humans and domestic animals. bongori to the level of species, as S. bongori, was proposed (Reeves et al., 1989). Khalid Gul, ... Ali Abas Wani, in Regulating Safety of Traditional and Ethnic Foods, 2016. Furthermore, they can carry fimbria. Usually, from the time of ingestion of contaminated food, symptoms develop within 12–14 h. The average mortality rate of Salmonellosis is 4.1%, varying from 5.8% during the early phase of life to 2% among middle-aged persons and 15% in persons over 50 years. Cells are rod-shaped, non-spore-forming, and predominantly motile by means of This genus consists of two species: Salmonella enterica and Salmonella bongori. M.T. The EU notification rate for confirmed cases was 21.5 cases per 100 000 population. Diagnosis of invasive disease can be problematic and relies on clinical findings as well as blood cultures and isolation of the organism. Salmonella infection in the gut is linked to diarrhea, fever, vomiting, and abdominal pain, and postinfectious irritable bowel syndrome (IBS) as a complication (Schwille-Kiuntke et al., 2011). Characteristics Salmonella enterica subsp. The latter is divided into six subspecies and more than 2500 serotypes. The subspecies of Salmonella are further separated into serovars according to the White–Kauffmann–Le Minor scheme. Histologically, enterocolitis with congestion, hemorrhage, and edema was observed and could be accompanied by focal necrosis in the gastrointestinal tract, spleen, and liver. Arnab Majumdar, ... Sutapa Bose, in Microbial Contamination and Food Degradation, 2018. Salmonella salamae Salmonella Subgroup IIIa: 1. Salmonella belongs to the species of Enterobacteriaceae family that are divided into two different groups, Salmonella enterica and Salmonella bongori.

Salmonella arizonae Salmonella Subgroup IIIb: 1. Clinical disease is likely exacerbated from comorbidities, stress of capture, and shipment. However, discrete investigations contradict the notion of strict host-specificity, as reports emerged of occurrence in dogs and birds. Liver from a bird naturally infected with Pasteurella, showing hepatomegaly and multifocal-coalescing pale foci of necrosis and hemorrhages. Pullorum disease: Almost all species of birds can get infected with S. pullorum, but only chickens, turkeys, guinea fowl, quail, and pheasant show clinical disease. [6] The first observations, from Messina and Palermo, starting from late 1984, were followed by other cities in Sicily. arizonae (Arizonosis), and other salmonella infection-causing serovars (Salmonellosis, paratyphoid infection) (Lister et al., 2008). Salmonella in domestic livestock is an important pathogen not only for risk of transmission to human, but also for the severity of the disease. Salmonella. There are more than 2500 known serovars. The percentage of human cases due to milk and dairy consumption is low respect to other source of infection: only the 3.4% of Salmonella foodborne outbreaks reported in EU in 2017 were connected with dairy products consumption, while 36,4% were due to consumption of eggs and egg products. [1] Species of Salmonella are closely related to E. coli and they are estimated to have diverged from a common ancestor about 100 million years ago; their genomes still display significant similarity, hence many functional identities. Many of the genes which are unique to Salmonella serovars, compared … Steven L. Percival, David W. Williams, in Microbiology of Waterborne Diseases (Second Edition), 2014. enterica serovar Derby (or Salmonella Derby). [5], Further, human infections have been substantiated, with conclusive reports from Italy. [5][7], Originally S. bongori was considered to be a subspecies within the genus Salmonella. Here, however, the fermentative pathway is the final electron acceptor i… Salmonella has long been recognized as an important zoonotic pathogen of economic significance in animals and humans. (2012). The case fatality rate of human salmonellosis in 2010 was 0.13%. The Roman numeral designations are used in … Salmonella is a widely distributed foodborne pathogen and one of the most common causes of bacterial foodborne illnesses and deaths globally .In the United States, Salmonella causes approximately 11% of foodborne illnesses, and is the principal cause of hospitalizations and deaths due to foodborne diseases , .The genus Salmonella includes two species (S. enterica and S. bongori … As the natural history of salmonellosis is poorly described in neotropical primates, criteria for initiation of antimicrobial therapy have not been established. The Salmonella genus is a member of the family Enterobacteriaceae and contains two species, Salmonella enterica and Salmonella bongori, each consisting of multiple serotypes. enterica (I), S. enterica ssp. Non thyphoidal Salmonella is a worldwide foodborne pathogen and the second most responsible for gastrointestinal human infections after Campylobacter spp. diarizonae (subspecies IIIb), S. enterica subsp. Salmonella pullorum 5. Keith G. Mansfield, James G. Fox, in The Common Marmoset in Captivity and Biomedical Research, 2019. Few clinical details are provided and cases were documented in marmosets recently imported from South America in the 1960s and 1970s. The genus Salmonella is a member of the family Enterobacteriaceae. According to the European Food Safety Authority, in 2010, a total of 99,020 confirmed cases of human salmonellosis were reported in the EU. arizonae (subspecies IIIa), S. enterica subsp. Serovars of Salmonella other than subspecies enterica are associated mainly with cold-blooded animals and rarely colonize the intestines of warm-blooded animals. Chaves Hernández, in Encyclopedia of Agriculture and Food Systems, 2014. The CDC (USA) has estimated that 8256 cases of salmonellosis occurred in 2010. DON decreases the villus height in the duodenum, leading to reduced numbers of enterocytes, suppressed digestibility, and malabsorption of nutrients (Antonissen et al., 2014). Shigellae can invade macrophages of the colonic and rectal M cells, resulting in the death of macrophages by apoptosis and as a result cause an acute inflammatory response with dysentery. Avian arizonosis is recognized mainly in turkeys but also is found in chickens and ducks. Enterotoxigenic Escherichia coli (ETEC), enteropathogenic E. coli (EPEC), enteroinvasive E. coli (EIEC), and enterohemorrhagic E. coli (EHEC) are well-known gastrointestinal pathogenic bacteria in humans and domestic animals. The genus is taxonomically divided into two species: Salmonella enterica and Salmonella bongori. These problems were overcome by the introduction of a new system, where each new type of Salmonella was named after the place in which it was first isolated. Salmonella is an enteric pathogen belonging to the family Enterobacteriaceae. is subdivided into 6 subspecies (enterica (I), salamae (II), arizonae (IIIa), diarizonae (IIIb), houtenae (IV) and indica (VI) ). I. Lasa, in Biofilms in the Food and Beverage Industries, 2009. S. enterica is subdivided into six subspecies: S. enterica ssp. bongori or S. choleraesuis subsp. Serotype subgrouping divides Salmonella into serotypes developed by Kaufmann and White – for example, S. enterica subsp. S. bongori was formerly classified as subspecies V. S. enterica ssp. Subspecies 1 of Salmonella enterica is responsible for almost all Salmonella infections of warm-blooded animals. The genus Salmonella can be divided into two species (S. enterica and S. bongori), based on their phenotypic profile. (formerly Salmonella choleraesuis) SYNONYM OR CROSS REFERENCE: Salmonella enterica spp. However, infection of pet animals is associated with diarrhea. Early identification of Salmonella species involved a descriptive of the disease it caused or the host with which the serotype was associated; this of course lead to major problems. As such, a majority of Salmonella bacteria have the following characteristics: 1. Salmonella is a Gram-negative, rod-shaped, motile bacilli which move with the use of its peritrichous flagella. Multilocus sequence typing as a replacement for serotyping in, The Common Marmoset in Captivity and Biomedical Research, Regulating Safety of Traditional and Ethnic Foods, Steven L.

These components are the O antigens, the phase 1 H antigens and the phase 2 H antigens. In severe cases, enrofloxacin or amoxicillin may be considered empirically until culture and sensitivity results are available and should be used in conjunction with supportive therapy and isolation of affected animals. Salmonella choleraesuis - 2500 serovars, 6 subspecies 2. enterica. Moreover, bacteriological culture allows to perform serotyping and genotyping of Salmonella isolates, and antimicrobial susceptibility test that provides several important information about the type of Salmonella isolated. Sequence accession description Seq. If the bacteria finds its way into a water supply or soil, through sewage or manure, then shellfish, … There are three major pathogenic species, Salmonella enterica, Salmonella bongori, and Salmonella subterranean. The majority of these cases are among children less than 3 years old, who are more prone to oral contact with animal droppings. Detection of Salmonella was reported in a wide range of foodstuffs, but most figures were from various types of meat and meat products. Salmonella bongori - 10 serovars 2. [1], It was discovered in 1966 from a lizard in the city of Bongor, Chad, from which the specific name bongori was derived. Subspecies I contains 99% of human-pathogenic serovars, including, among others, Enteritidis and Typhimurium, which are responsible for gastroenteritis in humans, and Typhi, a human-adapted serotype that is the causal agent of typhoid fever. The seven DNA-hybridization subgroups were designated as subspecies: S. enterica subsp. Low levels of oncogenic mycotoxins, such as aflatoxin or fumonisin potently increase EIEC-induced cytotoxicity (Baines et al., 2013). Salmonella diarizonae Salmonella Subgroup IV: 1. Ribeiro, in Encyclopedia of Meat Sciences (Second Edition), 2014. This classification scheme has historically undergone a number of rearrangements over time, as a result of the methodological improvements to reveal the true relationship between bacteria in this group. Arizonosis (S. enterica subsp. The Salmonella genus, member of the Enterobacteriaceae family, causes various diseases in humans and animals that range from gastroenteritis to typhoid fever. Strains of S. bongori, in particular, are rarely isolated from human patients (1, 2). S. enterica is further divided into six subspecies, S. enterica subsp. diarizonae (IIIb), S. enterica ssp. C. perfringens-induced necrotic enteritis lesions are mainly distributed in the duodenum and jejunum which are also the major absorption sites for DON. Immunologically, T-2 toxin-attenuated resistance to susceptibility to Salmonella infection is only partly associated with T- or B-cell responses in chicken models (Ziprin and Elissalde, 1990). Most people who get ill from Salmonella have diarrhea, fever, and stomach cramps. Observing the membrane ruffles and the formation of Salmonella-containing vacuoles in the host cells can identify macrophage invasion (Finlay et al., 1991; Monack et al., 1996). Among the different species of Salmonella, Salmonella choleraesuis had been showcased to produce the highest mortality rate of 21%. are members of the family Enterobacteriaceae. S. bongori is restricted to cold-blooded animals, whereas S. enterica may infect a variety of warm-blooded animals. : #20218] Salmonella bongori … In fact, currently, Salmonella serovars may be able to infect a wide phylogenetic range of hosts, from reptiles and birds to mammals, including wildlife animals and pets (Ashbolt and Kirk, 2006; Compton et al., 2008; Handeland et al., 2008; Smith et al., 2002). According to EFSA, in 2010, a total of 99 020 confirmed cases of human salmonellosis were reported in the EU. Salmonella gallinarum 3. The overall notification rate of human infection due to Salmonella in 2010 was 17.6/100,000 population, with a case fatality rate of 0.4%. enterica, salamae, arizonae, diarizonae, houtenae, bongori and indica. Salmonella houtenae Salmonella Subgroup V: 1. Salmonella typhi Salmonella Subgroup II: 1. The 99% of serotype causing infections in humans and warm-blooded animals belongs to Salmonella enterica subsp. Mortality is usually low, and less than 1% of reported Salmonella cases have been fatal. However, in some patients, the infection can be more serious and the associated dehydration can be life threatening. Salmonella bongori has 22 serovars (Grimont and Weill, 2007). In addition, it can cause chronic intestinal inflammatory diseases by damaging intestinal mucosal tissues in humans and domestic animals (Gradel et al., 2009; Jess et al., 2011). The Shiga toxin, released from S. dysenteriae type 1 binds to galabiose to initiate the inhibition of mammalian protein synthesis. They are gram negative, facultatively anaerobic rods. Fowl typhoid (Salmonella gallinarum infection): S. gallinarum causes disease mainly in adult or growing chickens and turkeys but also affects ducks, pheasants, guinea fowl, peafowl, grouse, and quail. The control measures to be applied include minimizing the possibility of contacts between all these animals and the cattle, and using rodent proof and bird proof feed storage, to avoid fecal contamination of feed. Mechanistically, DON-enhanced uptake of S. typhimurium into macrophages is due to F-actin reorganization of macrophage cells via activation of extracellular signal-regulated protein kinase 1/2 (ERK1/2) (Vandenbroucke et al., 2009). In developing countries, washing meat with fresh water is also reported to be a route of contamination; the meat becomes contaminated due to the direct discharge of waste into water bodies. Bacteriological culture can be performed on fecal samples or bowel content in dead animals, applying the specific analytical method codified by ISO (6579:2002) and relying on four basic steps. The genus Salmonella is divided into two species, enterica and bongori.The species Salmonella enterica is further subdivided into six subspecies that are designated by taxonomic names; these are sometimes abbreviated by Roman numerals. The type III secretion system (T3SS) encoded by the Salmonella pathogenicity island 2 (SPI2) has a central role in systemic infections by Salmonella enterica and for the intracellular phenotype. Salmonella are gram-negative, straight, rod-shaped bacteria (Fig. However, in some patients, the infection can be more serious and the associated dehydration can be life-threatening. Species of Salmonella are closely related to E. coli and they are estimated to have diverged from a common ancestor about 100 million years ago; their genomes still display significant similarity, hence many functional identities. Copyright © 2020 Elsevier B.V. or its licensors or contributors. [9] Also, the virulence determinants, specifically effector proteins, are indicated to be more closely related to enteropathogenic E. coli because some of the gene are missing in S. Salmonella bacteria arefacultative anaerobesthat are capable of fermenting glucose, mannitol, and sorbotol. Salmonella is one the most important species of the Enterobacteriaceae family and this genus is divided into two different species: Salmonella enterica and Salmonella bongori. However, based on DNA similarity, all members of Salmonella are now grouped into only two species, namely S. bongori and S. Salmonella consists of only two species, namely Salmonella enterica and Salmonella bongori. By continuing you agree to the use of cookies. The genus Salmonella comprises two species, Salmonella enterica and Salmonella bongori (). All PCR based methods show a higher sensitivity when performed starting from an enrichment broth than directly from the sample. (1982a, 1982b) suggested that all serotypes of Salmonella probably belonged to one DNA-hybridization group within which seven subgroups were identified. Salmonella london 3. The former contains 6 subspecies that are also classified in serovars according to the antigenic specificity. Results from multilocus enzyme electrophoresis (MLEE) studies supported that this observation, and the elevation of S. enterica subsp. Phylum Proteobacteria, Class Gammaproteobacteria, Order Enterobacteriales, Family Enterobacteriaceae, Genus Salmonella. Some Salmonella produce a surface polysaccharide and one example is Salmonella typhi, where the Vi antigen is very important in its identification. Among the lymphoid tissue components, macrophages are most influenced during the bacterial systemic invasion by Salmonella because the bacteria can survive and multiply in the macrophages after phagocytosis. enterica. While they are capable of using oxygen for respiration, they can also survive through anaerobic respiration by fermenting organic compounds. When Salmonella causes systemic infections, such as septicemia, effective antimicrobials are essential for treatment. ScienceDirect ® is a registered trademark of Elsevier B.V.

To investigate the relative contributions of homologous recombination to the genomic diversity of S. enterica subspecies, we compiled a total of 926 representative genomes downloaded from EnteroBase (see Table S1 in the supplemental material) (12, 25).We also included S. bongori because we hypothesized that recombination also occurs between … Fumonisin also suppresses the T cell-mediated immunity against ETEC infections; the hosts as carriers are then prone to longer bacterial shedding out, posing high risk in the bacterial reservoir (Devriendt et al., 2009). Nucleotide (GenBank) : AY116911 Salmonella bongori strain ATCC 43975 internal transcribed spacer 1, complete sequence. In fresh pig meat, 0.9% of tested samples were found positive for Salmonella and, in the case of fresh bovine meat, 0.2% of sampling units were positive. All strains of Salmonella have been placed in two species, Salmonella enterica and Salmonella bongori, dividing 2000 or so serovars into five subspecies or groups, mostly described under S. enterica, the major species (Le Minor and Popoff, 1987). Members of the other five subspecies (II–VI), found in the natural environment, are primarily parasites of cold-blooded animals. Destro, V.B. Since DON exposure is closely linked to intestinal barrier disruption, it can increase the bacterial translocation and toxin production by C. perfringens (Antonissen et al., 2014). enterica salamae arizonae diarizonae houtenae indica. Owing to the clinical importance of some of these serovars, the current nomenclature accepts the omission of the species in their nomination. However, these DNA–DNA hybridization studies suggested that DNA subgroup V (S. enterica subsp. NAME: Salmonella enterica spp. Figure 2. enterica (subspecies I), S. enterica subsp. Salmonella serovars are predominately pathogenic Enterobacteriaceae that are thought to have diverged from a common ancestor with Escherichia coli ∼100 million years ago .The genus Salmonella currently comprises two species; S. bongori and S. enterica, with S. enterica being comprised of 6 subspecies enterica, salamae, arizonae, diarizonae, houtenae and indica, , , , . Generally, minimum numbers living cells for gastroenteritis range between 105 and 106/g for Salmonella. Salmonella bongori is a pathogenic bacterium belonging to the genus Salmonella, and was earlier known as Salmonella subspecies V or S. enterica subsp. When Salmonella causes systemic infection, such as septicemia, effective antimicrobials are essential for treatment. Salmonella enterica is divided into six subspecies with approximately 2500 serovars. Although a low concentration (1–100 ng/mL, in vitro) of T-2 toxin enhances S. typhimurium invasion into the cells, higher doses of the toxin attenuate the bacterial colonization (Verbrugghe et al., 2012). For instance, Typhi and Paratyphi serovars exclusively infect human beings; S. Abortusequi causes abortion in horses; S. Abortusovis and S. Montevideo cause abortion in sheep; S. Dublin causes septicemia and abortion in cattle and abortion in sheep; and S. Gallinarum causes fowl typhoid (Tsolis et al., 1999b). There exists a great diversity in this genus, since we are dealing with an old pathogen that probably evolved from reptiles and adapted to mammals about two hundred million years ago. Introduction. With the introduction of more modern taxonomic techniques, Le Minor et al. [2] After decades of controversy in Salmonella nomenclature, it gained the species status in 2005. 1 left, electron microscopic depiction of a Salmonella cell with flagella, fimbria and pili; the line represents one-thousandth of a millimetre).The flagella arranged around the outer shell make lively movements possible. indica (VI). Taken together, exposure to some oncogenic mycotoxins causes failure of the host’s clearance of enterovirulent E. coli, allowing persistent bacterial colonization and pathogenic events, such as hemolytic uremic syndrome and renal failure. This group includes Salmonella enteritidis and Salmonella typhimurium. Salmonella is a member of the family Enterobacteriaceae. Mortality is usually low, and less than 1% of reported Salmonella cases have been fatal. Originally S. bongori was considered to be a subspecies within the genus Salmonella. Salmonella enterica is divided into six subspecies with approximately 2500 serovars. Salmonella enterica is subdivided into the subspecies enterica, salamae, arizonae, diarizonae, houtenae, and indica. Paratyphoid S. enterica produces typhlitis in young birds with dissemination toward the spleen, lungs, liver, spleen, and kidneys (Gast, 2013). The main risk for introduction of Salmonella infection in a farm is linked to the purchasing of asymptomatic shedders; consequently all the new cattle introduced in the farm should be isolated for 3 weeks and tested with a bacteriological culture. Salmonella paratyphi 4. Chronically affected birds show anemia and focal necrosis in the liver (Figure 2), heart, intestines, and pancreas (Lister et al., 2008). Figure 2. Salmonellosis is usually characterized by the acute onset of fever, abdominal pain, nausea, diarrhea, and sometimes vomiting after an incubation period of 12–36 h. Symptoms are often mild and most infections are self-limiting, lasting for a few days. Classification of Salmonella are facultative anaerobic Gram-negative bacilli, motile and non-lactose fermenter [ 8 ] Salmonella-specific.
