Abstract

Salmonella is the major cause of foodborne diseases and a serious public health problem in the world, with an increasing concern for the emergence and spread of antimicrobial-resistant strains. Our study was conducted to assess the prevalence and antimicrobial resistance profiles of Salmonella isolates using standard bacteriological methods. The overall prevalence rate of 11.4% was recorded from the total analyzed food items of animal origin. Salmonella isolates were detected from 5.7% of minced meat, 1.4% of kofta, 1.4% of luncheon, and 2.8% of burger. All Salmonella species recovered were resistant to amoxicillin-clavulanic acid with 100% sensitivity to ciprofloxacin and meropenem. Findings on the multidrug-resistant (MDR) profile showed that a total of 6/8 (75%) of Salmonella Enteritidis were resistant to 3 or more antibiotics. Therefore, our findings provide the prevalence and drug resistance of Salmonella from foods of animal origin and contribute information to scientists as well as public health researchers to minimize the prevalent and resistant foodborne Salmonella species in Egypt.

Highlights

Salmonella is a gram-negative bacterium that belongs to the Enterobacteriaceae family (Boyle et al 2007)
Infections caused by Salmonella spp. in farm animals have been documented as the leading cause of considerable economic losses worldwide (Jajere 2019)
Serotyping of Salmonellae Isolates: Serotyping of eight Salmonella isolates was applied by slide agglutination test using specific polyvalent “O” I, II, III and “H” Salmonella sera. four different serotypes were identified among selected Salmonella isolates; S. typhimurium was predominated with a higher percentage (50%) followed by S. enteritidis (25%), S

Summary

Introduction

Salmonella is a gram-negative bacterium that belongs to the Enterobacteriaceae family (Boyle et al 2007). Salmonella spp. are the most important bacterial pathogens among other foodborne pathogens and are responsible for causing gastroenteritis in humans (Ahmed & Shimamoto 2014). Enterica includes more than 2600 serotypes and is capable of infecting animals and humans (Crump et al, 2015). Infections caused by Salmonella spp. in farm animals have been documented as the leading cause of considerable economic losses worldwide (Jajere 2019). Salmonellosis is responsible for a variety of clinical syndromes, including enteric fever, which is usually caused by typhoid or paratyphoid species, enterocolitis, bacteremia, and severe local infections (De LeBlanc et al, 2010).
