Evaluation of garlic plant and indinavir® drug efficacy in the treatment of cryptosporidiosis in experimentally immumosuppressed rats

Abstract EN

The present study evaluated the efficacy of garlic plant and Indinavir® on cryptosporidiosis in experimentally immunosuppressed infected rats.

One hundred forty five Wister rats aging 3 weeks were divided into five groups : GI : normal control, GII : Indinavir treated control, GIII : immunosuppressed infected, GIV : immunosuppressed infected and treated with garlic and GV : immunosuppressed infected and treated with Indinavir.

All were subjected to clinical, parasitological and histopathological examination at different days post infection (P.I).

The results showed that in GIII, all rats had diarrhea, loss of appetite, weakness and limited movement, with 51.4 % death rate.

In both treated groups, some rats regained activities, with death rate of 33.3 % (GV) and non GIV.

There was significant decrease in the number of excreted oocysts at 5th and 10th day post treatment (P.T.) in treated groups.

One week P.T., in GIV, the number of excreted oocysts had continued in decreasing while in GV, it was insignificantly increased.

No cure rate was detected in both treated groups as oocysts still excreted till the end of experiment.

The histopathological changes improved in treated groups in spite of the presence of some parasites on the epithelial surfaces of ileum.
