Description

Bovine Imunodeficiency Virus (BIV) is a Lentivirus (non-oncogenic) which causes a persistent viral infection in cattle worldwide. It was first isolated in 1969 from a cow with a wasting syndrome.

Pathogenesis

The mechanism of transfer is not well knonw,but the following posibilites are being researched :

Transplacental
Transmammary
Vertical transfer through infected Semenn (e.g. Artificial inseminatio)

Clinical Signs

Bovine immunodeficiency Virus is not associated with a specific disease in cattle but has been associated with the folowing signs:

Decreased milk yield
clinical immunodeficiency
encephalitis
bovine paraplegic syndrome
skin infections
emaciation

Diagnosis

Western Blot
PCR

Treatment and Control

The Incidence of Bovine immunodeficiency virus appears to be low (1%) although can reach >15 % in some herds
