A paramyxovirus related to parainfluenza 2 (PI2) virus was recovered from the lungs of two dead Ottoman vipers from a zoological collection. Snakes of other species in the collection were unaffected. Histologic examination of the vipers' lungs revealed interstitial pneumonia, and degeneration and hyperplasia of bronchial and atrial epithelia. Scattered vacuoles, some of which contain eosinophilic inclusion bodies, were seen in the cytoplasm of several cells of affected epithelial tissues. The virus recovered from pulmonary tissues of the snakes replicated optimally at 30 C in a variety of cell cultures and hemagglutinated chicken erythrocytes. Viral hemagglutination was inhibited by PI2 virus antiserum, but not by antisera to PI1, PI3, respiratory syncytial, and canine distemper viruses. Indirect immunofluorescence with PI2 antiserum specifically stained inclusions in the epithelial cells of respiratory tissues and infected cell cultures.

This study determined the of involvement of PPR, PI3, and RS viruses in the pathology of caprine pneumonia across Nigeria. 150 goats were selected randomly. PI3 and RSV monoclonal antibodies and PPR polyclonal antibody were used for the immunolocalization of the antigens. Histologically, 61 of the goats had broncho-interstitial pneumonia, 25 had interstitial pneumonia, 42 had bronchopneumonia, 12 had bronchiolitis, and 10 were normal. PPR, PI3, and RS viral antigens were demonstrated in: intact and desquamated bronchial, bronchiolar epithelial cells, macrophages, leukocytes, pneumocytes, and giant cells. 23% of the caprine lungs had positive immuno-staining to PI3 viral antigen, 10% were positive for RSV antigen while 34% were positive for PPR viral antigen. 8% showed immunostaining for the two and or three respiratory viral antigens in the goats. PI3 and RSV antigens were more in the young goats, red sokoto breed and during the dry season. This is the first report of immunohistochemical detection of PPR, PI3 and RS viral antigens in caprine lungs in Nigeria. These findings underscore the importance of PI3 and RSV viruses in the control of caprine pneumonia in Nigeria.

There was a dearth of information on pathology and causal agents of bovine pneumonia in West Africa. This cross-sectional study conducted at four major metropolitan abattoirs in Nigeria and Ghana was to evaluate the pathology and to immunohistochemically demonstrates viral and bacterial pathogens of bovine pneumonia in West Africa. Out of the 20,605 cattle lungs examined at post-mortem using standard inspection procedures, 136 samples grossly showed pneumonic lesions and 99 randomly selected lung samples were fixed in 10% neutral buffered formalin for histopathological and immunohistochemical examination. The overall prevalence of pneumonia was 0.66%, with 0.72% prevalence in Ibadan, Nigeria and 9.68% prevalence in Ghana. Age and breed were observed to be among the predisposing factors to pneumonia in cattle. Histologically, bronchopneumonia (0.65%), broncho-interstitial pneumonia (0.13%), and interstitial pneumonia (0.08%) were the prominent type of pneumonias observed. Immunohistochemically, 0.8% was positive for bovine PI-3, 0.9% for bovine RSV, 1.0% for Mannheimia haemolytica (MH), and 0.6% for Pasteurella multocida (PM). There were a few interactions of pathogens: PI3 and MH (0.01%), RSV and MH (0.01%), PM and MH (0.02%). This was the first study that immunohistochemically demonstrated bacterial and viral antigens in naturally occurring pneumonia in cattle in Nigeria and Ghana.
