aspicularis tetraptera induced hematological parameters in infected and vaccinated mice

background: the present study deals with the effect of helminthic infection as nematode parasite like aspiculuris tetraptera on the haematological parameters of infected and vaccinated mice. methods: totally 15 mice were used. five mice were used for positive control, 5 mice used for nega­tive control and 5 mice used for experiment. the hematological parameters were studied viz. rbc, hb, and serum protein values. results: the mice carrying heavy infection showed decrease in the hb, rbc, and serum protein but in the vaccinated mice, all studied parameters were become on normal range. the level of immune response was assessed based on above studied hematological parameters in infected and vaccinated mice with aspiculuris tetraptera. conclusion: the increased value of rbc, hb and serum protein in infected and vaccinated mice compared to infected and non vaccinated suggested the involvement of blood parameters in immune response. this study also proves that somatic antigen of a. tetraptera was effective in imparting immunity in mice
