Prevalence and Antimicrobial Resistance ofSalmonellaIsolated from Animal-Origin Food Items in Gondar, Ethiopia

Abstract

Salmonella has been found to be 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. A cross-sectional study was conducted between February 2014 and December 2015 on food items of animal origin to assess the prevalence and antimicrobial resistance profiles of Salmonella isolates using standard bacteriological methods. The overall prevalence rate of 5.5% was recorded from the total analyzed food items of animal origin. Salmonella isolates were detected from 12% of raw meat, 8% of minced meat, 2.9% of burger samples, 18% of raw eggs, and 6% of raw milk. Furthermore, antimicrobial susceptibility test identified 47.6% resistant Salmonella isolates, 28.6% intermediately sensitive isolates, and 23.8% susceptible isolates. Among Salmonella isolates tested, 42.6%, 28.6%, and 14.3% were found to be relatively resistant to tetracycline, sulfamethoxazole-trimethoprim, and ampicillin, respectively, while 9.5%–19% were intermediately resistant to tetracycline, amoxicillin, ampicillin, cephalothin, and nitrofurantoin. 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 Ethiopia.

Carriage and antimicrobial resistance of non-typhoidal <i>Salmonella</i> in cattle slaughtered in Ambo municipality abattoir, West Shewa zone, Oromia, Ethiopia - a point prevalence survey

“…The multi-drug resistance (MDR) (35.3%) observed in the current study was higher than the previous MDR reported from Ethiopia ranging from 4% to 28.5% (Molla et al, 2004;Sibhat et al, 2009;Zewdu and Cornelius, 2009;Alemu and Zewde, 2012;Garedew et al, 2015;Ejo et al, 2016). The current MDR is lower than the finding of Addis et al (2011) The observed MDR in this study might be of great concern in the management of salmonellosis particularly in resource poor settings where new drugs are either absent or unaffordable.…”

“…In the current study, of the total NTS isolates, 35.3% (6/17) were found to be resistant to three or more antimicrobials. This is higher compared to some previous studies in Ethiopia (Alemu and Zewde, 2012;Ejo et al, 2016). Eguale et al (2016) reported that isolates of NTS from cattle feces were resistant to antimicrobials including streptomycin, nitrofurantoin, and ciprofloxacin.…”

“…This disease is common among children and old people. Most species of Salmonella are potential pathogens for humans and many of animals [3,4]. This species are placed in the gut of inflammatory diarrhea and food poisoning are considered [5].…”

“…The species are common in older children and adults. The bacteria have settled in the digestive system of vertebrates, including mammals, birds and fish and depending on the species, conditions and multiple factors of the host, can cause diseases with different symptoms and complications [3,[6][7][8]. Salmonella belongs to Entereobacteriaceae family and consists of 2200 species and more than 90% of species are human pathogens and other are animal pathogens, including typhi, typhimurium, enteritidis, Aynfantys species, etc.…”

“…This is one of the most common bacteria transferred from animals to humans which has a variety of host species. It is also considered as one of the most important factors in diseases transmitted via food and one of the major public health problem around the world [3]. Therefore, early detection of diseases caused by these bacteria is extremely important [9,10].…”
