HISTOPATHOLOGICAL EXAMINATIONS OF KIDNEYS IN PIGS AFFECTED BY CLASSICAL SWINE FEVER

摘要

Most of the previous histopathological examinations in cases of CSF described the changes in various parenchymal organs. Some of the findings were very typical, such as meningoencephalitis non-purulent, the haemorrhagic infarcts in spleen, etc. The kidney's pathology in CSF was not sufficiently studied. The aim of the present work is to study the histopathological changes in etiologically proven cases of spontaneous CSF. A total of 122 pigs were examined: 96 with spontaneous CSF and 26 healthy controls. The animals were divided into 4 groups: A - with fast acute form of CSF; B - with subacute and chromic form; C - asymptomatic form and D - healthy seronegative group. The organs were fixed in 10% formaldehyde and stained by several methods: hematoxylin-eosin, tolnidinblok, PAS (McManus); Conori silver impregnation; Van Gieson for differentiation of colagen.
