The majority (1590 local and 138 cross-bred) animals were found in mid-altitude while 724 local and 1004 crossbreed were found in high altitude representing Bahir Dar and Debre Berhan, respectively. Skin lesions were found in 2.4 % of animals examined out of which Dermatopholus congolensis was isolated from 22.6 (%). There was a higher prevalence (1.62%) in wet period than (0.46%) in dry period; (5.4 %) in cross-bred than (0.66) local breed cattle; (2.65) A. variegatum infested cattle than (0.44%) in A. variegatum none infested cattle, and (1.24%) in adult than (0.79 %) in young cattle with statistical significant (P< 0.05) difference between them in mid-altitude. There was also high prevalence (1.04%) in mid-altitude than (0.03%) in high altitude of the two seasons with a statistical significant (p < 0.05) difference, but a high prevalence (1.74%) in male than (0.77%) female with none statistical significant (p> 0.05) difference. According to the result obtained significantly associated risk factors with dermatophilosis have a high influencing contribution on the occurrence of the disease in the studied area (urban and periurban of Bahir Dar town).enDermatophilosisprevalencebovinerisk factorsThesis
