Afficher plus [+] Moins [-]Prevalence and antibiotic susceptibility of thermophilic Campylobacter isolated from freeranging ducks was determined in Morogoro Municipality, Tanzania. Ninety intestinal contents from ducks were screened for thermophilic Campylobacter using Skirrow’s protocol. Of the Campylobacter jejuni isolates, 50 were tested for sensitivity to 12 antibiotics. Overall prevalence of thermophilic Campylobacter was 80%. The prevalence of Campylobacter in adult ducks (91.3%) was significantly (p<0.05) higher than ducklings (68.2%). The isolation rate of C. jejuni (81.9%) was significantly (P<0.001) higher than C. coli (18.1%). All C. jejuni isolates were susceptible to streptomycin, nitrofurantoin and amikacin. Forty eight percent, 74% and 82% of isolates were resistant to cefuroxime sodium, tetracycline and ampicillin respectively. Between 20–50% of isolates were resistant to erythromycin, gentamicin, cloxacillin and amoxicillin. Norfloxacin and ciprofloxacin had lower C. jejuni resistance of 10% and 16% respectively. C. jejuni isolates from adult ducks showed significantly higher rates of resistance (p< 0.05) to most antibiotics than did duckling isolates.High prevalence of thermophilic Campylobacter in ducks could be of public health significance in Morogoro municipality. The observed multidrug resistance in this study poses a threat of transfer of antibiotic resistance to human pathogens because of the close contact between ducks and human.
