A total of 849 calves, 278 controls, 335 vaccinated intranasally with IBR-PI3/TS and 236 vaccinated intranasally with IBR-PI3/PTC were studied in a field trial of preimmunization. All calves were vaccinated in Saskatchewan at least three weeks prior to shipment to feedlots. Four hundred and twenty six calves were not sold within eight weeks of vaccination; however, seven of these died within four weeks of vaccination. Treatment rates varied from 1.0% to 5.2%. There was no significant effect of vaccination on treatment rates. Similarly, there was no significant effect of vaccination in the 74 calves sold to feedlots in Saskatchewan. Three hundred and forty nine calves were sold to feedlots in Ontario. Two of these died from fibrinous pneumonia. Treatment rates varied from 1.7% to 33.3% in different feedlots, but there was no significant effect of vaccination on treatment rates. Therefore, preimmunization is unlikely to significantly reduce the overall treatment rate in calves entering feedlots.

The results of three field trials of a live, cold-adapted, parainfluenza virus type 3 vaccine supported the hypothesis that infection with this virus initiates some ovine pneumonias. The serological response following vaccination was poor and only 22-44% of vaccinates developed a serum antibody response by two weeks after vaccination. Nevertheless, the prevalence of pneumonia was lower in vaccinated lambs in all three trials at the time that natural infection with PI3 was detected in the non-vaccinated lambs hut the differences were significant in only one trial. In some of the trials the number of deaths and the number of carcases downgraded or condemned because of severe pleural lesions were also lower and growth rates were higher in vaccinated lambs. The vaccine was specific for PI3; thus there was little effect on the prevalence of pneumonias occurring at other times in the absence of new PI3 infections. Nevertheless, this is the first direct evidence that any virus has a role in naturally occurring ovine pneumonias and the first indication that the prevalence of the naturally occurring disease may be reduced by vaccination.

The camel disease terminology of pastoralists in northern Kenya differentiates between two respiratory disease complexes of camels. Participatory epidemiology data were collected in 2011 in three camel keeping communities (Gabra, Garri, and Somali) and analysed to assess the validity of this differentiation. Further queries assessed recurrence of the disease in the same animal, most affected age group, relative frequency of occurrence, morbidity rates, mortality rates and response to antibiotic treatment. Based on matrix scoring the cardinal symptom nasal discharge was significantly correlated with Respiratory Disease Complex 1 (RDC1; Somali Hergeb, Gabra & Garri Furri) while cough was correlated with Respiratory Disease Complex 2 (RDC2; Somali Dhuguta, Gabra Qufa, Garri Dhugud). RDC1 appears to occur regularly every year and does not respond to antibiotic treatments while outbreaks of RDC2 are only observed at intervals of several years and treated cases do generally respond to antibiotics. While RDC1 is more severe in calves, RDC 2 is mostly associated with respiratory disease in adults. Elements of this differentiation appear to be in agreement with other authors who differentiate between camel influenza (PI3 virus) and bacterial camel pneumonia, respectively.

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.
