Severe diarrhoea due to Cystoisospora belli in renal transplant patient on Immunosuppressive drugs.

Cystoisospora belli , formerly known as Isospora belli, protozoal parasite endemic to many regions of the world including the Caribbean, Central and South America, Africa, and South-East Asia. It is frequently encountered in patients with acquired immunodeficiency syndrome (AIDS) and is considered to be an AIDS-defining illness. Chronic severe watery diarrhoea due to C. belli has also been reported in other immunodeficiency states. C. belli infection in immunosuppressed patients has rarely been described. We describe severe diarrhoea due to C. belli in a human immunodeficiency virus-negative renal transplant recipient on immunosuppressive drugs. Oocysts of C. belli were detected in direct smear preparation of the diarrheic stool sample of the patient. The patient responded to combination treatment with Bactrim-double-strength (trimethoprim-sulfamethoxazole) and Nitazoxanide.

Detection of bacterial growth in blood components using oxygen consumption as a surrogate marker in a tertiary oncology setup.

Microbiological contamination of blood and blood products is a well-recognised transfusion risk. This study was performed in the blood bank of our oncology centre, with an objective to detect bacterial contamination in our blood products using oxygen consumption as a surrogate marker [Pall Enhanced Bacterial Detection System (eBDS)]. Results revealed that the percentages of failed units were 1.16% for random donor platelets (RDP), 0.81% for single donor platelets (SDP) and 2.94% for packed red blood cells (PRBCs), of which one RDP and one SDP grew coagulase-negative staphylococcus, while one PRBC culture grew Gram-positive bacilli.

Human babesiosis--a case report.

Babesiosis is an emerging, tick-transmitted, zoonotic disease caused by hematotropic parasites of the genus Babesia. Most cases of Babesial infections in humans have been acquired in temperate regions of the United States, Europe, France and England. A few cases of Babesiosis have been described in other parts of the world, including China, Taiwan, Egypt, South Africa, and Mexico.1,2 We report the first case of human Babesiosis, in a normosplenic, previously healthy individual from India.

Early diagnosis of filarial pleural effusion.

This paper describes a case of pleural effusion due to filariasis. Microfilaria of Wucheraria bancrofti were detected in the pleural fluid on cytological examination. Treatment with diethylcarbamazine cleared the pleural effusion.
