| dc.description.abstract | During the present study, out of a total of 333 cases of bovine calves examined, 86 were found to exhibit gross lesions suggestive of chlamydial infection. Histopathologically, pneumonia and encephalitis was found in 60 (69.6 %) and 22 (25.6 ' A cases respectively. Chlamydia p_sittaci which was successfully isolated from a buffalo -calf reproduced the di sease when inoclzlated by a combination of intratracheal and intra-thecal routes into five buffalo -calves. The peculiar S i gla S in the infected buffalocalves included that of nervous disorder along with severe diarrhoea, and conjunctivitis. The high rise in temp..was associated with fall in haemoglobin content, leucccytosis and neutrophelia in the early stages. The major alterations in CSF included increase in total protein and progressive pleocytosis.Grossly, there was severe congestion and edema of the cerebrum and cerebellum along with typical consolidation of the antero-ventral lobes of the lung. In addition, excessive yellowiSh fluid with flakes of fibrin was present in the peritoneal cavity. Histopathological alterations in the lung included the presence of pen -bronchial and pen -vascular lymphocytic cuffing along with interstitial pneumonitis. The microscopic picture in the central nervous system was characterized by generalized vascular damage. There was proliferation of endothelial cells, pen -vascular lympnocytic cuffing along with focalnecrosis and gliosis. Nicroscopic changes in other organs have also been described. The detailed findings of the histoenzymic study in various body tissues have been described and discussed. The biochemical study was also carried out in various body tissues in addition to CSF and plasma. The acid -base analysis was carried out in venous blood and CSF of the infected buffalo -calves. While chlamydial organisms were demonstrated in various body tissues, by indirect FAT and Giemsa staining, they were also re -isolated from the infected buffalo -calves and were identified to be Chlamvdia psittaci. | |
