in this study one lymph node from cow with viral lymphosarcoma and one lymph node from healthy cow were analyzed by three different methods for protein extraction, include simple homogenizing in pbs, sonication and phenol extraction. tumor antigen detection relies on immunoprecipitation followed by sds-page. in this experiment streptococcus pyogenes was used for purification of immune compl...
H 0 fir e k B. , Mar taG ran' t 0 v , : Demonstration of Antibody to Bovine Leukosis Virus by the ELISA Test. Acta vet. Bma, 57, 1988: 133-146. The ELISA test and the iDlDunodiffusion test were compared for their suitability to detect antibody to bovine leukosis virus (BVL) in milk of dairy cows. Sensitivity of the immunodiffusion test in the determination of BLV antibodies in milk proved to be...
Deltaretroviruses such as human T-lymphotropic virus type 1 (HTLV-1) and bovine leukemia virus (BLV) induce a persistent infection that remains generally asymptomatic but can also lead to leukemia or lymphoma. These viruses replicate by infecting new lymphocytes (i.e. the infectious cycle) or via clonal expansion of the infected cells (mitotic cycle). The relative importance of these two cycles...
RAPD analyses have been used to determine the genetic diversity and the population structure of the endangered Blanca Cacereña bovine breed. Genetic variability was evaluated on the basis of 1048 loci produced by 71 primers. RAPD produced a number of polymorphic loci (30.44%), and it has been proved to be a useful method for evaluating polymorphisms in this breed. The dendrograms based on simil...
Blood samples were collected from healthy and mastitic cattle and buffaloes. Platelet Count, Prothrombin time, Activated Partial Thromboplastin Time and Fibrinogen Degraddation Products were estimated. There was no signi cant difference between healthy and affected animals.
