Seroprevalence and Presumed Bovine Leukaemia Virus and Coxiella burnetii Coinfections in Three Dairy Cattle Herds From the Al Ain Region, United Arab Emirates. [PDF]

Vet Med Sci
ABSTRACT Background Bovine leukaemia virus (BLV) and Coxiella burnetii are important infectious pathogens of dairy cattle with potential implications for animal health, productivity and zoonotic transmission (in the case of C. burnetii). Because BLV may alter immune function, we hypothesize that infection with the virus could increase cattle ...

Stage-Dependent Transcriptional Reprogramming of B-Cell Receptor Signaling and Antigen Presentation During Bovine Leukemia Virus-Driven Lymphomagenesis. [PDF]

Anim Genet
ABSTRACT Bovine leukemia virus (BLV), an oncogenic deltaretrovirus, establishes lifelong infection in cattle and induces enzootic bovine leukosis in a subset of animals following prolonged latency. Despite extensive evidence of immune dysregulation, stage‐specific transcriptional reprogramming of B cells, the primary viral reservoir remains ...

Capture in the metabolic arena: co-selection of gamma and deltaretrovirus envelope glycoproteins and their receptors [PDF]

Retrovirology, 2009
Although all infectious and replication-competent retroviruses harbor an env gene, the origin of env remains unknown except for that of a few invertebrate retroviruses. It is generally admitted that infectious retroviruses have evolved from endogenous viral retrotransposons by insertion of an ''external'' gene that encodes for a fusion glycoprotein ...

Comparison of the Prevalence of Bovine Leukemia Virus (BLV) in Holstein and Angus Cattle Breeds From Shandong Province, China. [PDF]

Microbiol Immunol
ABSTRACT Bovine leukemia virus (BLV) is widespread globally and causes economic losses in the cattle industry. Shandong Province plays a significant role in China's livestock industry, with an increasing importance in food of Holstein and Angus cattle. However, BLV prevalence in Holstein and Angus breeds in Shandong Province remains unclear.
