“…Among the serovars isolated, S. typhimurium was the most common serovar followed by Salmonella oslo. Similar findings are being reported by studies in Italy by Frasson et al [25]and in Africa by Karuiki et al [26]of S. typhimurium being the most frequent serovar causing non-typhoidal salmonellosis. This is in contraindication to studies reported elsewhere in the country.…”

Objective: Non-typhoidal salmonellosis is one of the leading zoonosis in the world caused by non-typhoidal Salmonella (NTS). Invasive infections with NTS serovars occurs due to the presence of virulence genes like invA along with the immunosuppressive conditions of the patient. The study was conducted to isolate and identify the NTS serovars and their antimicrobial resistance profile from patients with diarrhea and also to detect the virulence marker -invA gene among these NTS serovars.Methods: A prospective cross-sectional study was conducted from January 2015 to December 2016 at the Enteric Diseases Division, Kasturba Medical College, Manipal. 1218 fecal specimens were collected from patients with diarrhea and before antibiotic treatment. NTS serovars were identified, serotyped and then screened for the presence of invA virulence gene.Results: A total of 33 (2.7%) NTS was isolated. Salmonella typhimurium (33.34%) was predominant followed by Salmonella oslo (30.3%). Out of 33 NTS, invA was positive for 28 isolates (84.8%) of which 25 (89.3%) patients were febrile which was statistically significant (p=0.000). Conclusion:Non-typhoidal salmonellosis is an emerging global infection among immunocompromised patients. Our study showed an association between the invA gene and febrile illness among the patients suffering. Thus, this study highlights the importance of invA as a significant marker for bloodstream invasion.

Aims: To determine the prevalence and current sensitivity status of Salmonella enterica serovar typhimurium. Typhimurium to commercial antibiotics in cheese at the Southern Western part of Nigeria. Study Design: Experimental design. Place and Duration of Study: Cheese samples were bought from nomad cheese vendors across various suburbs in three major districts (Akure, Ikare and Owo) of Ondo state. Methodology: A total of two hundred and sixty (260) cheese samples were vended from various suburbs across the aforementioned senatorial districts of Ondo State. Isolation of Salmonella enterica serovar typhimurium. Typhimurium from cheese samples were carried out on Salmonella-shigella (S.S) and were identified biochemically through standard microbiological techniques. The identified strains were subjected to ten (10) conventional antibiotics for their sensitivity patterns. Results: The distribution patterns of the S. enterica serovar typhimurium. Typhimurium isolated were 9(47.4%), 8(42.10%) and 2(10.5%) in Ikare, Akure, and Owo respectively. The degree of resistance of the Salmonella enterica serovar typhimurium. Typhimurium to the various antibiotics used was 6.3% to Chloramphenicol (30 µg); 6.3% to Ofloxacin (10 µg); 6.3% of Sparfloxacin (10 µg); 12.5% to Streptomycin (30 µg); 18.8% to Sceptrin; 18.8% to Ciprofloxacin (10 µg); 25% to Gentamycin (10 µg); 31.3% to Amoxicillin (30 µg); 37.5% to Pefloxacin (10 µg) and 56.3% to Augmentin (30 µg). Conclusion: Cheese creates a favourable environment for a variety of microorganisms and can be important source of foodborne pathogens.
