Fasciolosis is one of the most important causes reduction in milk production, growth and fertility cattle considerable economic losses generated by liver seizures slaughterhouses. The objective this study was to determine occurrence livers seized Fasciola hepatica Lorenzo Gonzales bovine slaughterhouse Sagua la Grande municipality Villa Clara province, Cuba. A retrospective observational analys...

The goal of this study was to investigate the presence of bovine papillomavirus type 2 (BPV-2) genomic DNA using polymerase chain reaction (PCR) assays, in the urinary bladder of cattle with bovine enzootic hematuria (BEH), in the neoplastic and non-neoplastic lesions in Espírito Santo, Brazil. Thus, 46 bladders with gross BEH lesions were collected from adult cattle at slaughterhouses. The sam...

Systemic disease Lymphoma: A lymphoma was identified by histopathological examination of the sternal bone marrow of a 16 day old calf. The animal had exhibited bleeding from injection sites, and at postmortem examination widespread haemorrhages on internal organs were described by the practitioner. On the basis of the clinical and pathological findings bovine neonatal pancytopenia (BNP) was sus...

Bovine mastitis is a major disease affecting dairy cattle worldwide. The milk collected from cows with different type of inflammation, including mastitis, is characterized by an increased number of somatic cells (SCC), especially polymorphonuclear cells (PMN). It was proved that the antibacterial activity of PMN generates reactive oxygen species and nitric oxide-derived metabolites. The accumul...

Enzootic bovine leukosis (EBL) is a contagious lymphoproliferative disease whose etiological agent is a retrovirus, the bovine leukemia virus (BLV). EBL is a complex disease. So on after infection a strong humoral antibody response develops and persists for the animal 's entire life. Such BLV-infected cattle can remain asymptomatic virus carriers for many years. They can also at a given time de...

Bovine leukaemia virus (BLV) is a retrovirus that induces a chronic infection in cattle. Once infected, cattle remain virus carriers for life and start to show an antibody response within a few weeks after infection. Eradication and control of the disease are based on early diagnostics and segregation of the carriers. The choice of a diagnostic method depends on the eradication programme, money...

Avian leukosis virus induces tumors in chickens by integrating into the genome and altering expression of nearby genes. Thus, ALV can be used as an insertional mutagenesis tool to identify novel genes involved in tumorigenesis. Deep sequencing analysis of viral integration sites has identified CTDSPL and CTDSPL2 as common integration sites in ALV-induced B-cell lymphomas, suggesting a potential...
