A sample of stool was sent for AFB. We stained it with modified Z-N staining using 5% acetic acid as de-colorizing agent. We didn't found AFB but oocyst of cryptosporidium ( green arrow) found along with good number of candida. In case of chronic diarrhoea, most of the patients are being treated with different antibiotics without any obvious indication. So, Candida ( red arrow) overgrowth is very common, which may be missed in the diagnosis. In Bangladesh reporting on cryptosporidium infection is very rare.
