Title

DETERMINATION OF ANTIBIOTIC RESISTANCE AND IDENTIFICATION OF TETRACYCLINE (TET) RESISTANCE GENES IN SALMONELLA ENTERITIDIS STRAINS ISOLATED FROM FOOD SOURCES

Pages

  64-69

Abstract

 Background and Aims: Salmonellosis is an important disease among human animals and which is caused by different serovars ofSalmonella enterica. Serovars enteritidis and typhimuriumare the most prevalent serovars among human and animals which are the causes of foodborne infections. This study aimed to detect the antibiotic resistance pattern inSalmonella strains isolated from red meat as well as the molecular identification of TETRACYCLINE RESISTANCE GENES.Materials and Methods: In this study, 230 red meat samples were collected during 2015 from slaughterhouses, distribution centers and industrial processing plants around Tehran and were examined using culture and biochemical tests for the presence ofSalmonella isolates.Serotyping was performed using O and H antisera. Antimicrobial susceptibility testing was done for all the strains. Detection the tetracycline resistance gene was performed using Multiplex PCR and specific primers for thetetA, tetB, tetC and tet D genes.Results and Conclusions: A total of 60 Salmonella samples were isolated and identified.The serotyping results showed that all of the 60 samples belonged to group D and serovar enteritidis. The highest resistance was against amoxicillin and the lowest resistance against gentamicin. Twenty five percent of the samples showed phenotypical resistance to tetracycline, among which 60% had thetet genes, 7 isolates (46.6%) having the tetA gene, one isolate having thetetB and one isolate possessing the tetC gene. This study showed the prevalence of Salmonellaisolates in red meat samples and and the presence of TETRACYCLINE RESISTANCE GENES among these isolates.
