Abstract

OSTERTAGIA CIRCUMCINCTA is a major cause of ovine parasitic gastritis in temprate regions and the most frequent species affecting abomasum of small ruminants in Iran. These nematodes cause serious losses world-wide by imparing weight gain and wool production. Having a donor animal is essential for various studies. An OSTERTAGIA CIRCUMCINCTA donor was produced by transplanting of adult forms of this worm into abomasum of the lamb (9 months of age) through a surgically established cannula. Ten thousands infective larvae (L3) from the lamb’s faecal culture were given to another worm–free lamb of six months age through a STOMACH TUBE. Few eggs of O.circumcintca appeared in the cannulated lamb’s faeces, after 5 days of transplanting. The number of eggs per gram of faeces (EPG) increased in the following days. The average number of EPG reached up to 30± 14 per day. Very scanty number of eggs appeared, then, after 19-21 days of post-infection. However the number of eggs increased gradually, so that its daily average number of EPG reached up to 100±99 during 60 days of post–infection. Average number of eggs developmented to infective larvae (L3) was 35.1 percent. Although the number of eggs, laid by worms transplanted in cannulated lamb, was less than that of worms, grown from L3 in the abomasum, the abomasal CANNULATION method seems more preferable due to some advantages such as defined number of worms transplanted into abomasums, rapid access to the eggs and their culture and less loss of worm larvae during passing through the digestive tract.
