Salmonella bacteria arefacultative anaerobesthat are capable of fermenting glucose, mannitol, and sorbotol. The tray was kept undisturbed till the gel had solidified. The signs and symptoms of enteric fever are: Microscopic examination of Gram staining smear shows Gram-negative bacilli arranged mainly in single. The presumptive Salmonella spp colonies were subjected to gram staining and catalase tests. The route of infection is the fecal-oral route via food or water contaminated with faeces or urine of previously infected persons or animals (Orji et al., 2004). The genus Salmonella can be divided into two species ( S. enterica and S. bongori ), based on their phenotypic profile. After cooling for about 3 min, ethidium bromide (Biogene, USA) was added to the agarose solution to a final concentration of 0.5µg/ml. (2011), Vuthy et al. Perales, I and  Audicana, A. . (1998) respectively, were almost similar to the prevalence (34%) by cultural in the present study. (2016), Cheong et al. Taking into consideration of all issues of poultry industry, the present study was undertaken to study the prevalence of Salmonella spp in poultry products. Colonies on specific media are specific to Salmonella, all biochemical test are also specific, but serum gives me a negative reaction. All of the important human pathogen salmonellae belong to the subspecies. Salmonella ChromoSelect Agar is a selective medium used for simultaneous detection of Escherichia coli and Salmonella from food and water. Enteric fever is a generalized acute infection characterized by cyclic course, definitive temperature curve, general intoxication, bacteremia and affection of the lymphatic apparatus of the small intestine through which the infection implants itself in the host upon entrance of the causative agent into the gastrointestinal tract. Agarose gel (1.5%) was prepared by boiling agarose in an appropriate volume of 1X  TAE buffer. Cultural Characteristics of Shigella: They are aerobes and facultative anaerobes, grow best at 37°, pH 7.4 on ordinary media.

Keywords : Egg Shells and Cloacal Swabs Prevalence Poultry Meat Salmonella spp. The poultry farming in India has been seen as a lucrative business and has emerged as one of the major sources of the much-desired animal protein over the years. A link between the prevalence of Salmonella spp infection in poultry and human cases of Salmonellosis was identified in a risk assessment conducted by the Food and Agriculture organisation of the United Nations and the World Health Organisation (WHO, 2007). Blood, urine, stool, bone marrow, and aspirated duodenal fluid are suitable specimens for diagnosis of typhoid fever. More recent molecular studies have demonstrated that the genus Salmonella contains only two species that can be subdivided into seven subspecies. (2012), Murugkar et al. Moon, A. H. (2011). The efficiency of cultural method compared to PCR assay was 90.2%. (1994).Occurrence of, Jorgensen,F., Bailey,R., Williams,S., Henderson,P., Wareing,D.R.A., Bolton,F. Salmonella’s ability to change its phenotype and genotype in response to environmental changes make it almost impossible to eradicate from the food chain. High prevalence of 66.0%, 60.0%, 57.0%, 53.3%, 52.2%, 49.3%, 49%, 42.3% and 40% was reported by Jerngklinchan et al.

Salmonella cells experience gradual changes which is wh… (2019), Moon (2011), Kaushik et al. Eg: – Selenite F Broth – for the isolation of Salmonella, Shigella. (2012). Consequently, molecular typing techniques have been widely used to establish relatedness between Salmonella strains ( Deng et al., 2015 ; Foley et al., 2006 ; Taşkale Karatuğ et al., 2018 ; Tang et al., 2019 ). (2007), Suresh  et al. It can be extracted from the bacterial cell by treatment with phenol or alcohol. Prevalence of virulence and antimicrobial resistance genes in. When a culture of Salmonella was transferred to higher temperatures (60 C), it took 60 minutes to maximize heat resistance. Laboratory Protocol.“Isolation of, Zishiri, O.T., Mkhize, N and Mukaratirwa, S. (2016). Also, the last few decades have witnessed the emergence of highly virulent Salmonella spp, due to its extra-animal environmental strongholds causing greater morbidity and mortality in humans. Other media are differential and slightly selective, i.e., in addition to lactose and a pH indicator, they contain an inhibitor for nonenterics (e.g., MacConkey agar and eosin-met… The range of temperature for growth is 15‐41°C and the optimum pH for growth is 6.8. Vi‐antigen is a virulent (Vi for virulence) for mice. Non-typhoidal Salmonella spp is the most common form, responsible for the food borne salmonellosis and is carried by both humans and animals. The global burden of nontyphoidal. Grow on a general purpose or basal medium. Grow on a general purpose or basal medium. In the present study out of 50 cloacal swab samples 13(26.0%) and 14(28%) were positive by cultural and PCR respectively. Furthermore, they can carry fimbria. Some species exist in animals without causing disease symptoms; others can result in any of a wide range of mild to serious infections termed salmonellosis in humans. Humans become infected most frequently through contaminated water or food. respectively were custom synthesized by Xcelris labs limited are given in Table 1. It is aerobic and facultatively anaerobic. For serological test (Widal test) H suspension is prepared by addition of formalin to young motile broth culture. Some strains of E. coli are non-motile.

Type III secretion systems (bacterial proteins): Two separate type III secretion systems of bacterial proteins mediate the initial invasion of Salmonella into the mucosa of small intestine Other factors. J Korean Med Sci, 22,773-778. Within the subspecies, enterica, there are three serotypes; Paratyphi A, B, and C. These serotype… Salmonella infection (salmonellosis) is a common bacterial disease that affects the intestinal tract. Salmonellae produce non‐lactose fermenting pale colored colonies, which have the black center on DCA due to H2S production. The signs and symptoms of enteric fever are, Mental clouding of consciousness (typhus means cloud). Rothrock, M.J., Ingram, K.D., Gamble,J., Guard,J., Cicconi Hogan,K.M., Hinton,A and Hiett, K.L.(2015). (1999) respectively on the egg surface. DOI- http://dx.doi.org/10.5455/ijlr.20191011100139.
