Antibiotic resistance patterns, characteristics of virulence and resistance genes and genotypic analysis of Salmonella serotypes recovered from different sources
چکیده انگلیسی مقاله
The present study evaluated the
Salmonella
isolates obtained from various origins in Iran.
Salmonella
strains previously recovered and stored in the veterinary microbiology laboratory were serotyped and subjected to antibiotic susceptibility test, detection of the virulence and resistance genes by polymerase chain reaction (PCR), and genotyping by enterobacterial repetitive intergenic consensus-polymerase chain reaction (ERIC-PCR). All
Salmonella
isolates showed resistance to erythromycin and the most resistance rates were detected for trimethoprim (86.66%), ampicillin (75.00%), and sulfamethoxazole-trimethoprim (63.33%), respectively. In total, 86.33% of the isolates were known as multi-drug resistant and none of the isolates showed resistance to cefepime, nalidixic acid, imipenem, ceftriaxone, and polymyxin B. The virulence genes,
invA
,
sdiA
, and
hilA
besides the
tetA
resistance gene were identified in all 60
Salmonella
strains. The most prevalent resistance genes were respectively
tetC
(70.00%),
sul2
(58.33%), and
ereA
(55.00%). Statistical analysis revealed a significant difference between
Salmonella
serotypes associated with the
sul1
resistance gene. In ERIC-PCR analysis, 14 distinct clusters were obtained. Statistically, there were significant relationships between the source and ERIC’s genomic pattern and between the serotype of
Salmonella
isolates and genotypic pattern of ERIC. According to the results,
Salmonella
serotypes from non-human sources had considerable resistance to different antibiotics and carried significant virulence determinants and resistance genes. In addition, ERIC-PCR showed relevant results in discriminating
Salmonella
serotypes from other sources.
