Abstract
Dermatophilosis caused by dermatophilus congolensis, tick and lice and mites infestation, dermatomycosis affected a herd of 120 cattle obtained from different sources. Animals were bovine specie of various breeds including White Fulani, Gudali, Bunaji and their crosses, Male and Female; Aged from 2-10 years and weighing 250-500kg. Ticks were boophilus and amblyomma spp mainly, lice (lignognathus spp), mites (sarcoptes spp). Animals were kept to be slaughtered for food, observed body conditions made them unwholesome for human consumption. The major clinical lesions observed on the severely affected animals were extensive scabs and crust on the head, neck, dorsum, flanks, inguinal region and limbs involving above 20% of the herd; circumscribed thick grey-white crusts raised conspicuously above the skin around a central area of alopecia; general tick and lice infestation. Digestion of scabs with KOH revealed presence of mites which continually damages the skin so encourage proliferation of infectious organism. This case study portrait the general complaints of most cattle owners and traders. Contrary to the opinion of many authors for who tick infestation produce immune suppression of the host rather than mechanical and biological effect, the successful treatment with combination therapy using oxytetracycline long acting 20mg/kg deep IM and ivermectin 0.05mg/kg SC suggest there is a incumbent mechanical factor complicating the condition. Its removal brought about effective and prompt healing. Dermatomycosis (ring worm) was found to be self limiting, lesions progressively disappeared when dermatophilosis and ectoparasitic infestation was cared for.
Key Words: Dermatophilosis, ring worm, tick and lice infestation, cattle.
