[Some aspects of nitrogen metabolism in the liver tissue of chicks infected once and 3 times with a large dose of Eimeria tenella oocysts].

Studies of the contents of total, albuminous and residual nitrogen in the liver tissue of chickens at a single and 3-fold infection with 100 000 oocysts of E. tenella were undertaken. It was established that a single infection of 20-, 40- and 60-day old chickens is accompanied by a decrease in the contents of total and albuminous and an increase in the residual nitrogen. Their level is restored as a rule by the 20-th day after infection. In 40-day old chickens by the 20-th day after the 2-nd and 3-d infections, in contrast to non-immunized chickens the level of total and albuminous nitrogen increases. Residual nitrogen concentration remains in the standard ranges.
