Background: Avian malaria parasites (Plasmodium spp.) and related haemosporidians (Haemosporida) are responsible for diseases which can be severe and even lethal in avian hosts. These parasites cause not only blood pathology, but also damage various organs due to extensive exo-erythrocytic development all over the body, which is not the case during Plasmodium infections in mammals. However, exo-erythrocytic development (tissue merogony or schizogony) remains the most poorly investigated part of life cycle in all groups of wildlife haemosporidian parasites. In spite of remarkable progress in studies of genetic diversity, ecology and evolutionary biology of avian haemosporidians during the past 20 years, there is not much progress in understanding patterns of exo-erythrocytic development in these parasites. The purpose of this review is to overview the main information on exo-erythrocytic development of avian Plasmodium species and related haemosporidian parasites as a baseline for assisting academic and veterinary medicine researchers in morphological identification of these parasites using tissue stages, and to define future research priorities in this field of avian malariology. Methods:The data were considered from peer-reviewed articles and histological material that was accessed in zoological collections in museums of Australia, Europe and the USA. Articles describing tissue stages of avian haemosporidians were included from 1908 to the present. Histological preparations of various organs infected with the exo-erythrocytic stages of different haemosporidian parasites were examined. Results:In all, 229 published articles were included in this review. Exo-erythrocytic stages of avian Plasmodium, Fallisia, Haemoproteus, Leucocytozoon, and Akiba species were analysed, compared and illustrated. Morphological characters of tissue stages that can be used for diagnostic purposes were specified. Conclusion:Recent molecular studies combined with histological research show that avian haemosporidians are more virulent than formerly believed. The exo-erythrocytic stages can cause severe disease, especially in non-adapted avian hosts, suggesting the existence of a group of underestimated malignant infections. The development of a given haemosporidian strain can be markedly different in different avian hosts, resulting in significantly different virulence. A methodology combining the traditional histology techniques with molecular diagnostic tools is essential to speed research in this field of avian malariology.

Malaria parasites and packed cell volume offree range poultry was conducted on one hundred free range chickens collected from three communities in Abeokuta (Osiele, Lafenwa and Kuto). The results revealed that out of the 100 free range chickens examined, 13(13%) were infected with avian malaria parasite. Hematological parameter i.e. packed cell volume (PCV) revealed that chicken with PCV range 16-20 were 33.33% positive for malaria parasite. Others between PCV ranges 21 – 25 were 33.3%, while those between PCV ranges of 26 – 30 were 16.66% and those with PCV range of 31 – 35 were 16.67%.Chi-square analysis showed a significant difference between packed cell volume and malaria parasite(p<0.05). However, no significant difference was observed between sex and malaria parasite(p>0.05). The presence of avian malaria parasites in the study area could be of some epidemiological implications since the infected poultry could act as reservoir for malaria parasites.
