The present study describes pathologic and virologic findings in 15 sheep and 6 goats that died of natural peste des petits ruminants virus infection in Turkey. Pathologic findings included erosive-ulcerative stomatitis, fibrino-necrotic tracheitis, bronchointerstitial pneumonia, multifocal coagulation necroses in the liver, and severe lymphocytolysis in(More)
Neospora caninum, a protozoan parasite, has been considered as one of the most important etiological agents responsible for abortion in dairy cattle throughout the world since it was first identified in dogs in 1988. In this report, characteristics of neosporosis, detected in a dairy cow ranch having epidemic abortions as high as 18.4%, were described.(More)
Polioencephalomalacia (PEM) in ruminants has been recognized as a consequence of excess sulphur intake. The present study describes clinical, gross and histopathological findings of PEM following an abrupt change of diet in two ranches housing 2750 dairy and 2300 beef cattle. As a result of severe PEM, 256 cattle died or were slaughtered. Clinical findings(More)
The cerebellum is a steroidogenic organ that expresses steroidogenic enzymes and produces neurosteroids. Purkinje neurones appear to be the most active steroidogenic cells in the cerebellar cortex. These neurones express 3 beta-hydroxysteroid dehydrogenase (3 beta-HSD), P450 side-chain cleavage (P450scc), 17 alpha-hydroxylase/c17, 20lyase (P450c17), P450(More)
The prevalence and colonization sites of Helicobacter spp. in the stomachs of dogs, and their association with gastric pathology were investigated. Scraping cytology, culture, urease test and histology were used to detect helicobacters in the stomachs of necropsied dogs. Gastric Helicobacter spp. were detected in 103 (84.4%) of 122 dogs from 1 month to 14(More)
Concurrent infection with peste des petits ruminants virus (PPRV) and pestivirus was diagnosed in stillborn twin lambs. With the flock history, the findings of epidermal syncytial cells and necrotizing bronchitis/bronchiolitis prompted testing for PPRV infection, and PPRV antigen was detected by immunohistochemistry (IHC) in the skin, lungs, kidneys, rumen,(More)
The cerebella of eight dogs naturally infected with canine distemper virus (CDV) and two normal dogs were examined immunohistochemically for glial fibrillary acidic protein (GFAP) and 3beta-hydroxysteroid dehydrogenase (3beta-HSD). The clinical diagnosis of canine distemper was confirmed histopathologically and by the immunohistochemical demonstration of(More)
3β-Hydroxysteroid-dehydrogenase (3β-HSD) is an isoenzyme that catalyses an essential step in the synthesis of all classes of active steroid hormones. The presence of steroid hormones of the vertebrate type in invertebrates is acknowledged in addition to a group of steroid-like hormones called ecdysteroids that were present in arthropods and helminths. In(More)
The cerebella of 21 dogs with canine distemper virus (CDV) infection and four normal dogs were examined histopathologically and immunohistochemically. Cerebella of CDV-infected dogs showed nonsuppurative demyelinating encephalomyelitis, classified as acute, subacute or chronic. Immunolocalisation of CDV antigen also confirmed the infection. Tissues were(More)
The enzyme 3beta-hydroxysteroid dehydrogenase (3beta-HSD) is essential in the synthesis of all steroids by cleaving dehydroepiandrosterone to androstenedione. In the present study, 3beta-HSD immunoreactivity was investigated in the prostate of Akkaraman breed rams aged older than 3 years. Five normal and five hyperplastic ram prostates were processed for(More)
