Assessing cross-species transmission of hemoplasmas at the wild-domestic felid interface in Chile using genetic and landscape variables analysis.

摘要: The co-occurrence of domestic cats (Felis silvestris catus) and wild felids in rural landscapes can facilitate pathogen transmission. However, the relatively-isolated regions southern South America there have been no comprehensive studies to assess disease transmission risks between forest-dwelling such as guigna (Leopardus guigna). We evaluated hemoplasma infection possibility guignas by comparing spatial phylogenetic patterns prevalence. Blood/spleen samples were collected from 102 262 co-occurring across entire distribution range Chile. Hemoplasma was assessed direct sequencing 16S RNA gene. Infection with hemoplasmas common geographically widespread different bioclimatic areas for both species. most feline Mycoplasma species Candidatus M. haemominutum (CMhm) (15.7% guigna; 10.3% cat) haemofelis (Mhf) (9.8% guigna, 6.1% cat). A previously undescribed sp. sequence found two one cat. Continuous forest-landscapes associated higher hemoplasma-prevalence guignas. Shared nucleotide types rare, suggesting that cross-species may occur, but is probably uncommon. Ectoparasites, which linked transmission, not on infrequent cats. Our results suggest pathways vary among and, contrary our predictions, did appear be main driver these human-dominated landscapes.
