Observations on Sudanese camel nasal myiasis caused by the larvae of Cephalopina titillator.

Forty-four camels slaughtered at Nyala abattoir, western Sudan, were examined for infection with the larvae of Cephalopina titillator. The infection rate was found to be 100 p. 100. The parasitic burden ranged between 8-243 per animal. They were recovered throughout the year. The first stage larvae were noticed from December to May, indicating the breeding season of the fly. The larvae were found to cause visible pathological lesions on the nasopharynx. These were also demonstrated histopathologically. Bacteriological examinations revealed the presence of Pasteurella haemolytica and Klebsiella ozaenae as possible causes of pneumonia, and Corynebacterium species which could possibly cause pyogenic infections locally. Organisms from the camel environment like Bacillus and Proteus species were also isolated.
