    ANTIBIOTIC SUSCEPTIBILITY PATTERN OF SALMONELLA SPP. ISOLATES FROM FAECAL DROPPINGS OF COMMERCIAL AND FREE-RANGE CHICKENS IN SAMARU, NIGERIA
    (Departmentof of Agricultural Science, 2016-03-04) HILDA, ENABO
    Antibiotic susceptibility patterns of Salmonella spp. from faecal droppings of commercial and free-range chickens were determined. Six Salmonella spp. isolates were recovered from 200 samples of faecal droppings from live commercial and free- range chickens on Salmonella-Shigella Agar. The isolates were confirmed using standard biochemical tests. Susceptibility of the isolates was carried out by Disc Diffusion test: chloramphenicol, ciprofloxacin, cloxacillin, cotrimoxazole, gentamicin, nalixidic acid, streptomycin, and tetracycline. This study revealed that 100% of isolates from commercial chickens were susceptible to chloramphenicol, ciprofloxacin, gentamicin, nalixidic acid, streptomycin and resistant to cloxacillin, cotrimoxazole and tetracycline. However, the isolate obtained exhibited multi-antibiotic resistance to cloxacillin and tetracycline. Hundred percent of the isolates from free-range chickens were susceptible to ciprofloxacin, cotrimoxazole, gentamicin, nalixidic acid and streptomycin while 75% were susceptible to chloramphenicol. However, 100% were resistant to cloxacillin and tetracycline and all the isolates were observed to exhibit multi-drug resistance. The study has established the presence of antibiotic susceptible, resistant and multi-drug resistant Salmonella spp. isolates in commercial and free-range chickens to antibiotics in Samaru, Zaria. Multi-antibiotic resistance was higher in free-range
