The pathology of nasopharyngeal myiasis in Saudi Arabian camels (Camelus dromedarius).
Thirty-two out of thirty-five camels examined at Jeddah and Riyadh slaughter houses were infected with the camel nasal bot Cephalopina titillator. The larvae occurred mainly in the nasopharynx and, occasionally, degenerated larvae were found embedded between the turbinated bones. In the pharynx, the pathological changes included the formation of lymphoid nodules, with central abscesses, at the sites of larval attachment, and a combination of inflammatory, degenerative and reparative processes in other parts of the pharyngeal wall. The nasal cavity was congested and filled with mucus in which some larvae were entangled.
