“…The result of antimicrobial susceptibility testing in this study revealed that all Salmonella serotypes were 100% resistant to ampicillin, 90.6% to tetracycline, and 71.9% to streptomycin (Table 2). These results were not unusual as increasing resistance of non-typhoidal Salmonella to ampicillin, tetracycline, cotrimoxazole and chloramphenicol have been reported in many parts of the world such as the Netherland (Kivi et al, 2005), Singapore (Ling et al, 2002), Finland (Takkinen et al, Kenya (Kariuki et al, 2006b) and Nigeria (Akinyemi et al, 2007). Drug abuse, over the counter sales of antibiotics, use of antibiotics as growth promoter in animal and prophylaxis use of sulphamethoxazole-pyrimethamine for plasmodiasis were some factors linked to the increasing resistance to these antibiotics (Kariuki et al, 2006b).…”
