Description
Cristobal Castillo-Aliaga and colleagues published a 2026 study of feline leukemia virus in the guigna, a small wild cat of Chile and Argentina. The virus is common in pet cats and can spill into wild cats, with harsh effects. The team asked where guigna infections come from.
They sequenced the virus envelope gene from samples taken from five free-ranging guignas. The viruses were closest to strains found in Chilean pet cats, which points to spread from pets. Yet one distinct group, found only in guignas, suggests the virus also passes from guigna to guigna. All guigna samples formed a Chile-only branch apart from world strains of the main type.
