Isospora I think

 

[sanket_dalwadi]

its cryptosporidium parvum which is acid fast organism causing self limiting watery diarrhea in IC pts. also resistant to chlorination

But isospora is also acid fast and causes diarrhea in HIV patients

The correct answer

It's funny how they play with us with words. Elliptical is a round shape with the stretched horizontal axis while oval is a round shape with elongated vertical axis. Isospora has elliptical shaped eggs. You can try TMP/SMX for treatment. Cryptosporidium has oval eggs. No treatment is successful. The correct answer is A
