A survey was carried out to characterise the bacterial and mycoplasma flora of a closed colony of marmosets, Callithrix jacchus. Bordetella bronchiseptica and Staphylococcus aureus were the only potential bacterial pathogens isolated from the colony; Candida albicans was also identified. S aureus and C albicans were the only organisms which were associated with macroscopic lesions or overt disease. Post mortem examination of the animals proved only reliable method of establishing the presence of some bacterial species in the colony, eg, B bronchiseptica and of obtaining a reliable estimate of the incidence of the various organisms within the colony. The marmosets were all infected with ureaplasmas in the upper respiratory tract. Mycoplasma salivarium was isolated from this site in several animals. There was no evidence to indicate that cross-infection had occurred between the animal technicians and the marmosets, except in one possible case of candidiasis.

The occurrence of diarrhoea in calves was monitored during the first three weeks of life. Calves fed amounts of colostrum sufficient to produce serum Ig levels in excess of 30 mg per ml did not develop diarrhoea, whereas calves fed less colostrum did. Rotaviruses and mycoplasma-like particles were observed in the faeces of calves with and without diarrhoea. The epidemiology of rotavirus infection in calves is discussed.

Extensive pneumonic lesions were present in 42 out of 43 calves obtained for post mortem examination from 34 outbreaks of respiratory disease in Northern Ireland. Bronchiolitis and alveolitis with necrosis of bronchiolar mucosa which progressed to bronchiolitis obliterans and peribronchiolar fibrosis were prominent histopathological features in the lungs of calves obtained live. The majority of calves which died within the first two months of these outbreaks had severe exudative bronchopneumonia with marked vascular damage and necrosis of pulmonary parenchyma. Pasteurella spp, Mycoplasma spp and P13 virus were the organisms most frequently recovered from the pneumonic lungs.

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.

An inactivated virus vaccine containing strains of parainfluenza type 3 (PI3), bovine adenovirus type 3, reovirus type 1, bovine virus diarrhoea (BVD) and infectious bovine rhinotracheitis (IBR) viruses was tested in a group of 58 calves reared in a semi-intensive management system. Following vaccination, 1/30, 14/30 and 17/30, showed significant rises in antibody titre to reovirus type 1, adenovirus type 3 and IBR respectively. None of the animals showed significant serological response to PI 3 and BVD. In the control group, 2/28, 1/28, 6/28 and 3/28 developed antibody responses to reovirus type 1, BVD, adenovirus type 3 and IBR respectively. Microbiological examination revealed the presence of a wide variety of commensal bacteria and Mycoplasma bovirhinis in both groups. Analysis of the records of clinical examinations indicated that the respiratory tract infections occurred among the calves at between 50 and 80 days after arrival at the farm, and that there was no significant difference between the test and the control groups. A number of animals had maternal antibodies to the various components of the vaccine present before the trial commenced and these antibodies appeared to interfere with the subsequent serological response to the antigen challenge. The vaccination schedule recommended by the manufacturer does not entirely circumvent this problem.

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.

The results of an enzyme-linked immunosorbent assay (ELISA) For the detection of antibody against Mycoplasma mycoides subsp mycoides are presented. Antibody was detected in the sera of cattle at least 19 months after recovery from an infection and at least 23 months after vaccination. Almost half the sera of some animals in an area of Nigera where contagious bovine pleuropneumonia is enzootic contained antibody. Antibody was rarely detected when the same sera were examined by other established serological tests, emphasising the sensitivity of the ELISA.

An infectious keratoconjunctivitis occurring in goats in the Sudan is described. Experimental transmission using infective ocular discharges resulted in a conjunctivitis in young kids and a severe keratoconjunctivitis in an adult goat. A pleomorphic organism which resembled Rickettsia spp was found in conjunctival smears from naturally and experimentally infected animals. Neither Mycoplasma nor Chlamydia spp were isolated in microbiological cultures.

The results of a serological and cultural study of experimental and field cases of contagious caprine pleuropneumonia were consistent with an aetiological role for mycoplasma strain F38. This mycoplasma was isolated from 57 acute cases in 46 outbreaks of CCPP and from 87 experimental contact cases. Clinical data from experimental contact cases were assessed for comparison with field cases.

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.
