The effect of age on the susceptibility of pigs to M.hyopneumoniae was evaluated in this study. Two experiments were carried out. In both experiments, exposure of experimental pigs was provided by contact with M.hyopneumoniae-inoculated pigs. Exposure time was 27 and 20 days, respectively, in Experiments A and B. Pigs were 3, 6 and 12 weeks of age at the start of Experiment A and 3 and 11 weeks of age in Experiment B. The three age groups of pigs from Experiment A werehoused by age in three units until necropsy 6 weeks after exposure began. Pigs from experiment B were kept isolated from each other in smidley hog houses until 7 weeks after exposure began when they were euthanized. Sentinel pigs were housed in houses between those of contact-exposed pigs in ord er to detect aerosol infection. No differences were observed between age groups of pigs in occurrence and severity of MPS lesions or in detection of M.hyopneumoniae in lung tissue. These observations suggest that pigs from 3 to 12 weeks in age are equally susceptible to MPS. a Good association was found between isolation of M.hyopneumoniae, immunofluorescence test results and presence of macroscopic and microscopic lesions of MPS. In spite of this fact, the lack of complete agreement between these factors indicates that for definitive diagnosis a battery of test is needed. Direct and indirect immunofluorecence tests were equally efficient for detection of antigen in cryostat lung sections. Indirect immunofluorescence appeared to be more appropriate for .......
