Prevalence, serovars, phage types, and antibiotic susceptibilities of Salmonella strains isolated from animals in the United Arab Emirates from 1996 to 2009

Abstract

The aim of this study was to give some insights into the prevalence, serovars, phage types and antibiotic resistances of Salmonella from animal origin in the United Arab Emirates. Data on diagnostic samples from animals (n= 20871) examined for Salmonella between 1996 and 2009 were extracted from the databases of the Central Veterinary Research Laboratory in Dubai and from typed strains (n= 1052) from the Robert Koch Institute, Wernigerode Branch in Germany and analysed for general and animal specific trends. Salmonella were isolated from 1928 (9%) of the 20871 samples examined. Among the 1052 typed strains, most were from camels (n= 232), falcons (n= 166), bustards (n= 101) antelopes (n= 66) and horses (n= 63). The predominant serovars were S. Typhimurium (25%), S. Kentucky (8%), followed by S. Frintrop (7%) and S. Hindmarsh (5%). When analysed by animal species the most frequent serovars in camels were S. Frintrop (28%) and S. Hinmarsh (21%), in falcons S. Typhimurium (32%), in bustards S. Kentucky (19%), in antelopes S. Typhimurium (9%) 2 and in horses S. Typhimurium (17%) and S. Kentucky (16%). Resistance of all typed Salmonella strains (n= 1052) was most often seen to tetracycline (23%), streptomycin (22%), nalidixic acid (18%) and ampicillin (15%). These data show trends in the epidemiology of Salmonella in different animal species which can be used as a base for future prevention, control and therapy strategies.

Molecular epidemiology and antimicrobial resistance of Salmonella species from clinical specimens and food Items in Lebanon

“…Concerning animal related studies, a study carried out in Lebanon showed that S. Typhimurium, isolated from ten different animals, was the first and the second most common serotype of Salmonella to be isolated from chickens and cattle, respectively [21]. In United Arab Emirates, S. Typhimurium and S. Enteritidis were the first and fourth most frequently isolated serotypes from animals [22]. In line with this, our results showed that S. Typhimurium was the most frequently isolated serotype from food samples.…”

“…Concerning food related studies, a study done by Harakeh et al (2006) showed that Salmonella serovars from meat based fast foods exhibited a very high resistance to trimethoprimsulfamethoxazole and a moderate resistance to cefotaxime [29]. Similarly, a study done in the United Arab Emirates for a period of 14 years concerning antimicrobial susceptibilities of Salmonella serovars in animals revealed that the resistance to ampicillin and ciprofloxacin has been declining in contrast to trimethoprim-sulfamethoxazole to which the resistance has been rising [22]. Our study, on the contrary, showed that: Salmonella in food samples had the highest resistance to ampicillin followed by ciprofloxacin and all the isolates were susceptible to trimethoprimsulfamethoxazole.…”

Isolation and Antimicrobial Susceptibility of Salmonella Typhimurium and Salmonella Enteritidis in Fecal Samples from Animals

“…It is important to consider that some studies from around the world have reported ciprofloxacin resistant Salmonella [7], particularly in less frequent serovars [23]. Since this antibiotic is widely used in human salmonellosis it should be included in future epidemiological studies to monitor the development and spread of resistance to this antimicrobial in different countries and regions worldwide.…”

“…The indiscriminated use of these compounds makes difficult the treatment of bacterial infections in animals and humans [23].…”
