Haemoparasites in endemic and non-endemic passerine birds from central Mexico highlands

This study included 157 passerines representing 29 species from 17 families. Overall, 30.6% (48/157) of the birds were infected with blood parasites. Of those, Haemoproteus spp. were found in 14.0% (n=22), Leucocytozoon spp. 12.1% (n=19) and microfilariae 0.6% (n=1). Blood parasites were found in 71.4% (5/7) of endemic bird species and 45.4% (10/22) of non-endemic species. Medium to high parasitaemia (number of parasites/number erythrocytes) was observed in birds with infections of Haemoproteus spp. and Leucocytozoon spp. Co-infections 3.8% (n=6) were observed in two species of endemic birds. This study contributes to the knowledge of haemoparasites in endemic and non-endemic passerine birds from central Mexico highlands. Additional investigation on the molecular identification of haemosporidian parasites, pathogenicity and health status of these birds is necessary.Graphical abstractTriple infection: Haemoproteus spp. (), Leucocytozoon spp. (), and microfilaria (➤) parasites (A) of a Catharus occidentalis (B).
