ABSTRACT
Abstract: Pigeon lice are insects that feed on feathers of these birds; their life cycle includes egg, nymph and adult and they may cause dermatoses in humans. Four persons of the same family, living in an urban area, presented with widespread intensely pruritic erythematous papules. A great number of lice were seen in their house, which moved from a nest of pigeons located on the condenser of the air-conditioning to the dormitory of one of the patients. Even in urban environments, dermatitis caused by parasites of birds is a possibility in cases of acute prurigo simplex. Pigeon lice are possible etiological agents of this kind of skin eruption, although they are often neglected, even by dermatologists.

In this study, five goats naturally infested with Sarcoptes scabiei, Psoroptes ovis and Bovicola caprae were treated with a combination of ivermectin and clorsulon. A subcutaneous injection in a dose of 1 ml/50 kg live weight was given. This provided dose levels of 200 ug ivermectin and 2 mg clorsulon. Four goats were cured from the three ectoparasites within one to two weeks. The last elder goat which was anemic and naturally infected with Trichostrongylus colubriformis was still infested with the two scab mites but was free from B. caprae. A postal dose of 0.5 ml/50 kg live weight was given one week later. This goat was cured within a week, but still passed some T. colubriformis eggs. The results of this study were presented and discussed

Out of 304 goats, 218 were infested with three species of lice [Bovicola caprae, Linognathus africanus and L. stenopsis]. Infestation with more than one species of lice was also seen. The highly infested season was winter and the least one was spring. The highly infested body site was hip and the least infested one was britch. The economic loss of goats infested with lice was discussed
