The clinical, parasitological and pathological findings in a group of six donkeys naturally infected with D arnfieldi larvae are described. One animal had to be sacrificed at an early date because it developed pneumonia. The remaining five were unthrifty, showed mild clinical respiratory signs and had heavy strongyle infections. They had varying numbers of adult worms in the airways of the lungs and eggs were found coiled up in the smaller bronchi where they had apparently lead to an obstruction to airflow in that segment. The most striking gross pathological changes were circular discrete areas of over-inflation surrounding such bronchi. Histologically the infected bronchi exhibited a marked bronchiolitis with goblet cell hyperplasia and a mainly lymphoid inflammatory infiltrate. These areas also showed a localised bronchiolitus and overinflated alveolar tissue although true emphysema was not present. It is postulated that the parasite is well-adapted to its host and is able to survive for long periods within the lung without causing a debilitating amount of damage to the host. The immunological aspects of the infection are discussed briefly.

An outbreak of acute severe pneumonia which affected six to 14-week-old single-suckled calves, resulted in 45/77 requiring treatment. The examination of paired sera from all affected calves revealed that neither an adenovirus, non infectious bovine rhinotracheitis virus nor parainfluenza 3 virus was involved. The acute exudative interstitial pneumonia found at post mortem was typical of pneumonic pasteurellosis.

Both porcine cytomegalovirus (PCMV) and Bordetella bronchiseptica produced rhinitis and pneumonia when inoculated intranasally into young gnotobiotic pigs. With PCMV the nasal lesions were confirmed to the lamina propria, while Bordetella produced atrophy of the turbinate bones and hyperplasia and degeneration of the nasal epithelium. Some exacerbation of the lesions was observed in the nasal mucosa of pigs given both agents, but the degree of bone atrophy was not increased.

A detailed study of a population of dogs with kennel cough was undertaken. Twenty-seven (77 per cent) of a total of 35 dogs had pathological evidence of respiratory disease in the form of tracheobronchitis with, in some animals, exudative pneumonia. A variety of viral and bacterial agents were isolated from the respiratory tract of diseased dogs but Bordetella bronchiseptica and canine parainfluenza virus SV-5 appeared to be the most significant organisms recovered.

In 47 of 50 outbreaks of respiratory disease in indoor calves which had never been to grass there was clinical evidence of pneumonia in all animals examined. Calf housing was in most cases considered unsatisfactory. Virus activity was detected in 70 per cent of outbreaks investigated within a few days post onset of respiratory signs. Parainfluenza (PI) 3 and respiratory syncitial virus (RSV) were the viruses most frequently involved. In the majority of outbreaks Mycoplasma species and Pasteurella multocida were present in the upper respiratory tract of affected calves.

In four outbreaks of indoor calf pneumonia, dyspnoea was a prominent clinical finding. At necropsy it was associated with pneumonia involving the cranial lobes of the lung and severe pulmonary emphysema. Histological examination of lung tissue revealed bronchiolitis and alveolitis with alveolar epithelial cell hyperplasia and multinucleate syncytium formation. Intraalveolar haemorrhage, intra-alveolar oedema and hyaline membrane formation were also noted. In all cases parainfluenza type 3 (PI3) virus was isolated from the lungs. In each of the four outbreaks there was evidence of PI3 virus and respiratory syncitial virus (RSV) infection.

Thirteen colostrum deprived calves were inoculated with a low passage field strain of parainfluenza type III (PI 3) virus. Virus was administered by the intranasal route and the calves were experimentally infected twice daily for four consecutive days. Clinical signs of respiratory disease were noted and pneumonia was present in 12 animals at necropsy. PI 3 virus was isolated from the lung lesions and no other respiratory pathogens could be demonstrated. The pneumonic lesions grossly, histologically and in their distribution resembled those encountered in naturally occurring outbreaks of indoor calf pneumonia.

A new method for quantitative detection of antibodies to Mycoplasma suipneumoniae in pigs' sera has been developed by the application of an enzyme-linked immunosorbent assay (ELISA). The results show that the ELISA is specific and highly sensitive. In experimentally infected pigs antibodies could be detected several weeks before the clinical manifestation of enzootic pneumonia.

An isolate of Chlamydia psittaci from ovine pneumonia produced extensive pneumonia in red deer after endobronchial inoculation. Associated clinical signs lasting for several days included pyrexia, inappetance, increased pulse and respiration rate, and physical distress after handling, but no coughing or upper respiratory symptoms. Histologically, an acute exudative reaction was present after two days, and an early proliferative response after seven days. Both the clinical and pathological responses were more marked than those usually associated with chlamydial pneumonia in other large animals after endobronchial infection. A small survey for chlamydial antibody in wild red deer was negative.

In a control scheme for enzootic-pneumonia-free herds, 43 herds developed enzootic pneumonia, as judged by non-specific clinical and pathological criteria over 10 years. Material for cultural examination was obtained from 32 of these outbreaks, and Mycoplasma suipneumoniae was identified in 28 of them. The four failures occurred before 1971 at a time when the cultural techniques were clearly inferior. Since 1971 M suipneumoniae has been isolated from all the 17 outbreaks sampled for this purpose. Two of the outbreaks from which M suipneumoniae was not recovered, and three further outbreaks, were closely connected with outbreaks from which M suipneumoniae had been isolated (to make 33 out of 35). The remaining eight outbreaks (in which isolations of M suipneumoniae were not attempted) were clinically and pathologically consistent with the pattern of the others. Hence, there is reason to believe that during this period the outbreaks of respiratory disease simulating enzootic pneumonia in the control scheme have probably all been associated with the presence of M suipneumoniae.
