Detection of some antibiotic resistant genes within Salmonella serovars isolated from broiler chickens

الملخص EN

This study aimed to examine the sensitivity of different antibiotics against 10 Salmonella serovars isolated previously from broiler farms.

After that, all resistant serovas were detected genetically for the presence of qnrA, blaTEM, tetA (A) and aadB resistant genes.

Two S.

Typhimurium, one S.

Kentucky, one S.

Newport, one S.

Tamale, one S.

Enteritidis, one S.

Molade, one S.

Takoradi, one S.

Virchow and one S.

Inganda were examined sensitivity against different antibiotics by disc diffusion method.

The resistant serovars to quinolones, β lactams, gentamycin and doxycyclin were confirmed genetically.

The results showed that emerging of multidrug resistant strains to common antibiotics in the poultry field required newly discovered herbal compounds for control the disease and prevent the resistant phenomena.
