Abstract

Avian hemoprotozoans can cause mild to severe clinical disease in pet birds. Avian hemosporidian parasites comprises Leucocytozoon, Hemoproteus and Plasmodium. They are single celled, intracellular parasites in which the fertilisation, formation of zygotes and asexual sporogony take place in a blood-sucking dipteran vector. Sexual gametogony and asexual merogony occur in avian host. Most of them have undergone extensive co-evolution with their natural hosts. Although these blood parasites are widely present, their distribution is based on both avian hosts and vectors. Blood parasites are distinguished based on developmental stage in host blood stream. Relapse of parasitic infection usually takes place during the breeding season of avian host, facilitating transfer of infection to offspring. Delayed reproduction, reduced clutch sizes, reduced parental working capacity while feeding nestlings and increased predation risk, especially during situations of stress that deteriorate the host condition are some of the effects of blood parasites on the host.
