Screening of blood parasites in local and migratory wild birds of Israel
| Resumo: | ABSTRACT - Between March and April 2018, a parasitological survey was performed on wild birds admitted at the Israeli Wildlife Hospital, in Ramat Gan, Israel. Ninety-one birds belonging to ten different families and twenty-three different species were analyzed. The prevalence rate of positive samples for at least one parasitic genus was 48.4% and, more specifically, 36.3% for Plasmodium spp., 29.7% for Leucocytozoon spp., 26.4% for Haemoproteus spp., and 13.2% for Aegyptianella sp. The family Accipitridae had the highest prevalence for overall parasitism (76%), as well as for each genus. All host-parasite relationships found, except for the ones regarding Aegyptianella sp. and some of the ones concerning Leucocytozoon spp. and Plasmodium spp., were already described in the literature. As far as the author is concerned, this is the first report of Aegyptianella-like organisms in Buteo buteo, Buteo buteo vulpinus, Falco tinnunculus and Milvus migrans species, as well as of a Leucocytozoon sp. infection in Falco biarmicus and Larus armenicus, and a Plasmodium sp. infection in Pernis apivorus and Larus armenicus. This study assessed the possible relationship between the presence/absence of these parasites and relevant clinical and hematological parameters. Significant differences (p<0.05) were found between the age groups, packed cell volume status, presence/absence of weakness, eosinophil count, lymphocyte count and total solids according to the presence/absence of some of the parasites, as well as overall blood parasitism. This research contributed for a broader knowledge of Israeli wildlife parasite fauna and a better understanding of the importance that these parasites have in terms of ecology and conservation of the birds studied; |
