Cryptosporidiosis in a tertiary care hospital.

BACKGROUND

Cryptosporidium, an important cause of diarrhoea, has been reported worldwide both in immunocompetent and immunocompromised individuals and has emerged as a serious public health problem. This study was undertaken to assess the present status of cryptosporidiosis in children and adults with diarrhoea who attended the Nehru Hospital, Chandigarh which is a tertiary care hospital.

METHODS

Routine stool examination was done using saline and iodine stained preparations for various parasites. Modified Ziehl-Neelsen and rapid safranin-methylene blue techniques were used to detect Cryptosporidium in 2000 stool samples (1645 adults, 355 children) from March to November 1998.

RESULTS

Of the 2000 samples, 205 (10.2%) were positive for various parasites. Five (1.4%) children were positive for Cryptosporidium and one child was positive for human immunodeficiency virus. In adults, Cryptosporidium was found in only one patient (0.06%). Giardia lamblia was the commonest parasite detected both in adults (4%) and children (15.2%).

CONCLUSION

The present study highlights the importance of Cryptosporidium as a cause of diarrhoea, especially in children. Thus, there is a need for specific staining techniques to detect Cryptosporidium in routine diagnostic laboratories.
