Somkiat Trongwongsa
A survey for the occurrence of Microfilaria in the blood of 40 elephants age ranged from 3-55 years (approximately). Two ml of blood obtained by venopuncture from the ear vein was carried out. Blood smears were examined for Microfilaria by Modified Knot Technique. Blood from 38 out of 40 elephants were positive. All blood positive elephants showed no signs of illness except one whose blood had Microfilaria over 30 per one slide which is considered heavy infestation. No adult worms were found within the heart chambers at necropsy of 6 elephants age ranging from 3-60 years.
