ABSTRACT
Dermatophilosis is an infectious disease of domestic and wild animals, and to a certain extent man. This paper presents a naturally acquired infection of cattle with Dermatophilus specie in an institutional farm in Zaria, Nigeria. The infection which occurred in a herd of 67 cattle involved 10.4% (7/67) showing crust lesions. Crust samples were taken from each of the seven infected animals and cultured on blood agar for the isolation of Dermatophilus specie. The isolates obtained were subjected to biochemical test and also antibiotic sensitivity test. All the seven isolates were found positive with Gram stain and β-hemolysis. They did not produce gas with sucrose, mannitol and maltose but were positive with catalase and urease, and negative for indole. The isolates were sensitive to Amikacin (80%), Ciprofloxaxacin (80%), Doxycyline (60%), Ceftriaxone(60%), Chloramphenicol (40%) and Colistin sulphate (20%).In conclusion all the seven infected cattle were confirmed positive for Dermatophilus congolensis and were found to be highly sensitive to Amikacin and Ciprofloxacin. It is hereby recommended that the infected cattle should be treated with Amikacin or Ciprofloxacin. Regular ectoparasite control should be carried during raining season in the farm.
