Musa MS, Hamid ME., Prevalence of dermatophilosis in sedentary and nomadic cattle in Sudan, Onl J Vet Res., 26 (2):148-156, 2022. Bovine dermatophilosis (streptothricosis) is a severe skin infection of ruminants in the tropics caused by Dermatophilus congolensis. We report prevalence in sedentary and nomadic herds in 9409 cattle in Darfur, Sudan. Clinical, bacteriological and tick infestation data was compared with history from stockowners, incidence and mortality. We found overall prevalence of 4.1% and mortality 1.1% but was higher (P < 0.02) in sedentary cattle (7.82%) compared with nomadic ones (3.04%). We associate this with heavy persistent tick infestation in sedentary cattle. Adult females were found to be more (P < 0.05) susceptible (3.7%) than adult males (2.14%) or calves (2.04%).
