Flashcards

Lumpy Skin Disease (LSD)

An acute, infectious, but non-contagious disease of cattle causing skin nodules and other symptoms.

Capripoxvirus

The virus that causes lumpy skin disease in cattle.

Cow-Buffalo pox (CBP)

A contagious viral disease of cattle, buffalo, and humans, causing pox lesions on the skin.

Orthopoxvirus

The genus of viruses that includes cowpox and buffalopox.

Economic impact of LSD/CBP

Both diseases lead to losses in animal productivity, milk production, and secondary mastitis. LSD also damages hides and reduces draft ability.

LSD/SGP Virus Susceptibility

Cattle (especially calves) and buffalo are susceptible to LSD & SGP viruses. Wild animals might be affected, too, but less severely. Humans are rarely affected, acting as a zoonotic reservoir.

Transmission of LSD/SGP

LSD/SGP is transmitted mechanically (insects), directly (contact), indirectly (contaminated equipment), through introduction of infected animals, and via infected milk.

Source of LSD/SGP Infection

LSD/SGP viruses can be found in skin lesions/crusts (live up to 40 days), nasal/lacrimal secretions, semen, milk of infected animals, fluids and scabs.

LSD/SGP Viral Differentiating

LSD and SGP viruses can't be distinguished with standard blood tests, but the gene GPCR (G-Protein Coupled Chemokine Receptor) can be detected by PCR.
