Abstract: | From 1978 to 1983, 411 bird submissions consisting of 911 birds were received in our laboratory for diagnosis. Filariasis occurred in four submissions (0.97% of total) consisting of four birds (0.44% of total), and microfilariasis was diagnosed in 34 submissions (8.27% of total) consisting of 123 birds (13.5% of total). Adult filariae were found in the abdominal air sacs of two cockatoos and two red lories and identified as Cardiofilaria sp. Although filariasis and microfilariasis in birds are found world-wide, there seems to have been no report made previously in Indonesia. |
