Pathology of pulmonary acariasis in Baboons (Papio sp.).

Pulmonary acariasis is one of the important and more frequently observed spontaneously occurring diseases in African baboons (Papio sp.). It has been found more frequently in baboons in their native habitat than in those in captivity. Prevalence also varies with the sites of captivity. Histopathologic changes occurring in the lungs due to infection with Pneumonyssus santos diasi and P. mossambicensis are described.
