Merogony of Toxoplasma gondii (Apicomplexa: Coccidia) and its effect on the mortality and histopathology in the house mouse Mus musculus.
Merogonic stages of Toxoplasma gondii, their effects on the mortality and histopathological changes in the orally-inoculated male house mice Mus musculus with low and high doses (LD&HD) of T. gondii sporulated oocysts was investigated. The mortality percentage in LD group was 16%, 20%, 28% and 72%, while that in HD group was 36%, 56%, 72% and 100% in the 1st-4th week, respectively. Meanwhile, the maximum mortality percentage of the control group reached 6%. The histopathological changes induced by the parasite in different organs such as kidneys, liver, brain, spleen, heart, lungs and testes were discussed.
