Intestinal parasites detection among haemodialysis-patients in Sohag University Hospitals

Patients undergoing haemodialysis are considered to be immunocompromised, i.e. more susceptible to opportunistic organisms including parasites. Faecal samples were collected from 50 randomly picked patients subjected to haemodialysis in the renal dialysis unit of Sohag University Hospital. Each sample was cultured on a modified agar plate, subjected to formol-ether and sucrose sugar concentration methods then modified Zeil-Neelsen [MZN] acid-fast staining technique. Parasites were found in 94%, of the specimens, 84% were found to acquire mixed infection. Detected helminths included: Strongyloides stercoralis [24%], Enterobius vermiculaus [4%] and Anleylostoma duodenale [2%], while protozoa included: Entamoeba histolytica [56%], Entamoeba coli [58%], Entamoeba hartmani [2%], Giardia lamblia [58%], lodamoeba buetschlii [20%], Isospora belli [4%], Chilomastix mesnili [2%], Cryptosporidium parvum. [48%], Cyclospora cayetanensis [12%] Microsporidia [2%]. Comparison between the used diagnostic methods revealed that modified agar culture plate was significantly, better [P=0.004] in diagnosing S. stercoralis, while MZN stain was statistically better in diagnosing C. parvum [P-0.009], and distinguishing Cyclospora cayetanensis and Microsporidia

Psychoda albipennis maggots [Diptera: psychodidae] as a cause of urinary myiasis in an upper Egyptian male, the second World case

A case of urinary myiasis with the manifestations of urinary tract discharge, frequency and burning micturation in a 21 years old Upper Egyptian male was described. Eleven larvae of the Psychodid fly [Psychoda albipennis] were recovered from his urine. The maggots were diagnosed, described and photographed. Psychoda albipennis maggots as a cause of urinary myiasis is here to be the second recorded case in the world
