Resumen
Human transformation of natural habitats facilitates pathogen transmission between
domestic and wild species. The guigna (Leopardus guigna), a small felid found in Chile,
has experienced habitat loss and an increased probability of contact with domestic
cats. Here, we describe the interspecific transmission of feline leukemia virus (FeLV)
and feline immunodeficiency virus (FIV) between domestic cats and guignas and assess
its correlation with human landscape perturbation. Blood and tissue samples
from 102 free-ranging guignas and 262 domestic cats were collected and analyzed
by PCR and sequencing. Guigna and domestic cat FeLV and FIV prevalence were very
similar. Phylogenetic analysis showed guigna FeLV and FIV sequences are positioned
within worldwide domestic cat virus clades with high nucleotide similarity. Guigna
FeLV infection was significantly associated with fragmented landscapes with resident
domestic cats. There was little evidence of clinical signs of disease in guignas. Our
results contribute to the understanding of the implications of landscape perturbation
and emerging diseases.
