Iron and Ferritin Levels in the Serum and Milk of Bovine Leukemia Virus-Infected Dairy Cows
Iron metabolism was examined in 15 bovine leukemia virus (BLV)-infected dairy cows (2.6-7.8 years old). BLV infection was detected by measuring serum antibody titer against BLV virus antigen (gp51). The anti-BLV antibody titers of the BLV-infected cows were significantly higher in serum than in milk; a single serum-positive animal lacked detectable anti-BLV antibodies in its milk. Iron and ferr...
متن کاملThe prevalence of bovine viral diarrhea virus in persistently infected cows in industrial dairy herds in suburb of Mashhad- Iran
Bovine Viral Diarrhea Virus (BVDV) is a Pestivirus of the Flaviviviridaefamily that infects cattle, and its widespread distribution can cause substantial economic losses worldwide. The aims of this study were: (1) to estimate the prevalence of animals persistently infected (PI) with BVDV in industrial dairy cattle herds in suburb of Mashhad- Iran; and (2) to compare the occurrence of persistent...
متن کاملVariation in the bovine FABP4 gene affects milk yield and milk protein content in dairy cows
Fatty acid binding proteins (FABPs) bind long-chain fatty acids and are involved in their intracellular transport. Of the known bovine FABP genes, FABP4 has been mapped to a region on chromosome 14 that contains quantitative trait loci for milk traits. This study investigated the association of FABP4 haplotypes with milk production traits in 719 Holstein-Friesian × Jersey cows. Polymerase chain...
متن کاملGlucocorticoid Receptors in Peripheral Blood Lymphocytes from Bovine Leukemia Virus-infected Cows with Persistent Lymphocytosis1
Bovine leukemia virus-infected cows with persistent lymphocytosis have an expanded population of B-lymphocytes in the peripheral blood that is sensitive to glucocorticoids in vitro and in vivo. We examined peripheral blood lymphocytes from cows with persistent lymphocytosis for the presence of specific glucocorticoid receptors. Steroid binding in intact cells was determined by a whole cell comp...
متن کاملGlucocorticoid effects on peripheral blood lymphocytes in cows infected with bovine leukemia virus.
We examined the effects of glucocorticoids on peripheral blood lymphocytes (PBL) in lymphoproliferative conditions associated with bovine leukemia virus (BLV): persistent lymphocytosis (PL) and lymphosarcoma cell leukemia (BLSL). The effects of hydrocortisone 21-sodium succinate (HSS) on spontaneous incorporation (SI) and mitogen-stimulated incorporation of radiolabeled-thymidine and the effect...
