EFFECT OF RADIATION ON VIABILITY AND INFECTIVITY OF NEMATODIRUS SP. EGGS
Abstract
In this study, effects of different levels of gamma irradiation on the hatching ability of Nematodirus sp. Eggs and infectivity of irradiated larvae in Angora goats were investigated. Nematodirus sp. Eggs were exposed to radiation doses ranging from 1 to 300 Gy. It was fonud that there was no significant differences with respect to hatching ability between the control and irradiated groups of eggs in low doses such as 1, 5,10 and 20 Gy when larval development in eggs were examined. The results show that there is an inverse relatonship between the gamma radiation dose used and the hatching ability of eggs after the dose of 30 Gy. The more the radiation dose level, the lesser the hatching was observed and there was no hatchings after the dose of 225 Gy. Moreover, degenerative changes in the developments and multiplications of blastomrs relating to increases of radiation doses were observed. The differences between the control group and irradiated groups (starting from 30 Gy) were found to be statistically significant (P<0.05). Twelve Angora goats were infected with each receiving 500 Nematodirus sp. Larvae irradiated with doses of 0, 30, 50 and 100 Gy. All animals were sacrificed and worm counts were performed 28 days after infection. It was determined that there were decreases in the egg and worm counts and delayed egg sheddings with the increases of irradiation doses and no worms were obtained at a dose of 100 Gy. Also, the survival of more females than males in the collected parasites was found.
