Protozoan diseases of pet birds
|
Haemoproteus
-
It is the largest and most commonly encountered blood parasite group, containing nearly 200 species and varieties. Manly transmitted by hippoboscid flies.
-
Haemoproteus rarely been incriminated as the causal agent of mortality in avian population.
Plasmodium
-
The canary appears to be highly vulnerable to most malarias under experimental condition. P. gallinaceus, P. lophurae and P. relictum are more virulent.
-
The clinical signs include listless and anorexia, bird will stop preening and other normal behavioural activities.
-
Anemia, edema of the eyelids, emaciation, and sudden death are frequently seen.
-
Necropsies frequently reveal serous hemorrhage and hepato and splenomegaly.
-
Control is best achieved by elimination of mosquito vectors.
-
Avian malarias such as P. gallinaceum tend to respond to treatments with antimalarial drugs like chloroquine 5mg/kg body weight and proguanil at 7.5mg/kg body weight.
-
However the same drug with other avian malaria species have little or no effect.
