| Abstract | ||
| Hydatiosis is a widespread chronic zoonotic parasitic disease caused by helminthic larval stage of tapeworm Echinococcus granulosus.. In last year's many methods are used to activate and modulate the response of immune system of the host in order to evade the invasion of the parasite. The present investigation was aimed to find out the effect of attenuated protoscolices on the viability of lymphocytes which play very important role in the immune response against many parasites and the reflect of this attenuation on hydatid cyst protoscolices infectivity in vivo. Four groups of white male BALB/c mice were experimentally infected with helium-neon laser attenuated protoscolices that exposed to helium –neon laser for (10,30,50,100) minutes respectively. The results showed increase in lymphocyte viability (p<0.01), especially among mice that exposed to laser for 50 minutes (77.00±1.42) in comparison to control group(50.66±3.23),this increase in lymphocyte viability causes statistically (p<0.01) decrease in protoscolices infectivity (both cyst numbers and diameters)in comparison with positive control group which cause decrease in lymphocyte viability. | ||
