Drug resistance of Salmonella spp. isolated from pigeon eggs

Brief Communication


Avian Salmonellae infections cause not only clinical disease in poultry but are also recognized as a source of food-borne disease transmission to humans. Domestic pigeons usually live in urban and rural areas in close proximity to human residential areas. Although their role in transmission of different infectious organisms is important from public health point of view, there are few reports available on Salmonella infections and their resistance to antibiotics in pigeon. In order to study pigeon egg contamination to the Salmonella spp. and the drug resistance pattern of the isolated organisms, pigeon egg shells were cleaned and disinfected with 96% ethanol. The contents of each egg was emptied into a sterile petri dish and incubated at 37°C for 24 h. Isolates were finally confirmed by PCR, using specific primers targeting the invA gene sequences from Salmonella spp. The results of this study showed that 5.7% of pigeon eggs had Salmonella spp. contamination. Disk diffusion test on Muller–Hinton agar was used to determine the sensitivity to antibacterial agents. Study of resistance to antimicrobial agents of isolated Salmonella spp. among the ten antibiotics showed a high frequency of sensitivity to ciprofloxacin, norfloxacin, gentamycin, and chloramphenicol (100%), and a high level of resistance to tetracycline (50%) was observed.
