Abstract
Village weavers (Ploceus cucullatus) are ubiquitous passerine birds found in Nigeria. Researches on avianhaemoparasites in domestic and wild birds in Nigeria have been receiving considerable attention over theyears. In recent studies, the commonly reported haemoparasites include Haemoproteus sp, Plasmodium sp.,Leucocytozoon, Hepatozoon and nematode microfilariae. These haemoparasites have been associated withseveral pathologic changes and diseases in affected birds. However, there is dearth of information on theprevalence of haemoparasites associated with village weaver in Nigeria. This present study evaluated theprevalence of haemoparasites in village weavers birds found in Ibadan, Nigeria and the associatedhaematological changes. 30 weaver birds were captured from the suburb of Ibadan, Oyo State, Nigeria. Thebuffy coat smears of the birds were made to ascertain the prevalence of haemoparasites using lightmicroscopy to determine the morphological characteristics of the haemoparasites observed. Themorphological characteristics of the haemoparasites observed were consistent with Haemoproteus spp.,Leucocytozoon spp., Plasmodium spp., and microfilariae. Out of the total number of the village weaverssampled, 22 (73.33%) had one or more haemoparasites. Haemoproteus spp was observed in 19 (63.33%)birds, microfilariae was seen in 10 (33.33%) while 7 (23.33%) had Leucocytozoon spp with Plasmodium spp.in 5 (16.67%), being the least prevalent in this study. The co-i
nfection with different haemoparasites wassignificant (p<0.05) which indicated an increased relative risk of a superimposed haemoparasite infection inalready infected birds. The erythrocyte parameters and indices (PCV, RBC, MCV, MCH and MCHC) wereslightly higher in the uninfected weaver birds than in the haemoparasite infected population.
