abstract

background: salmonellosis is one of the most importantzoonotic diseases throughout the world. objectives: thepurpose of this study was to characterize a large collection ofsalmonella isolates from different poultry sources in iran.methods: a total of 123 salmonella isolates from differentpoultry sources were subjected to drug susceptibility test,hemolysin production, motility test, and plasmid profile (50isolates). results: seventy-one resistance patterns were foundto 29 antimicrobial agents among 123 salmonella isolates, inwhich 81% of isolates were resistant to more than oneantibacterial agent. the resistance patterns of 123 isolates to 10commonly used antibacterials in iranian poultry industry werealso quite variable and included 31 patterns. four differentplasmid patterns were found among 50 salmonellaisolates. fiftyfour percent of salmonella isolates harbored one or threeplasmids with approximate molecular size ranging from 2.3 to68 kb. no plasmid was detected in 46% of isolates. aband of 68kb size was detected in all isolates that harbored plasmid. allisolates were motile but no isolate showed hemolysinproduction. conclusions: the frequency of resistance toantibacterial agents among avian salmonella isolates is a majorpublic health concern.

Phenotypic and genotypic studies of extended spectrum beta-lactamase (ESBL) resistance among Salmonella isolates from poultry sources in Iran

BACKGROUND: Poultry and poultry products are among the major sources of Salmonella infections for humans. Increasing occurrence of antimicrobial resistance among Salmonellae has become a serious public health concern. The detection of extended spectrum b-lactamase (ESBL) producers among Salmonella spp. has increased in recent years. OBJECTIVES: The purpose of this study was to investigate the a...

Occurrence of multidrug-resistant Salmonella enterica serovar Enteritidis isolates from poultry in Iran

Salmonella enterica is recognized as one of the major food-borne pathogens with more than 2,500 serotypesworldwide. The present study addresses antimicrobial resistance of Salmonella enterica serovar Enteritidisisolates in Iran. A collection of 151 Salmonella spp. isolates collected from poultry were serotyped toidentify Salmonella Enteritidis. Sixty-one Salmonella Enteritidis were subsequently...

Molecular Characterization of Ampicillin Resistant Poultry Isolates of Salmonella Typhimurium

Multiple drug resistance and high genetic variation among the field isolates are one of the two major constrains in eradication and control of Salmonella Typhimurium from poultry. In the present study 51 isolates of Salmonella typhimurium which were isolated from eggs were analyzed for their responses against commonly used sixteen antibiotics. Genetic variation among these isolates was studied ...
