Abstract
P. larvae larvae, the causal agent of American foul brood disease (AFB), was characterized and isolated from larvae with clinical symptoms and asymptomatic adults of honeybees obtained from Uruguayan apiaries. The susceptibility of P. larvae larvae isolates to oxytetracycline hydrochloride (OTC) was also investigated. All examined isolates from larvae and adult honeybees were Gram positive rods and spores were observed after 10 days in culture. All isolates were susceptible to OTC at 5 micro g, and the minimum inhibitory concentration was <2.5 micro g/ml.
