BACKGROUND As a waterborne pathogen, Cryptosporidium is one of the most common causes of gastroenteritis in human and hoofed livestock animals. This study aimed to investigate the distribution of Cryptosporidium spp. in human and livestock wastewaters in Iran, by the 18S rRNA sequence analysis. METHODS A total of 54 raw wastewater samples collected from three urban treatment plants and two sl...

BACKGROUND Cryptosporidium is an important cause of diarrhoeal disease in children and immunosuppressed persons. It is an opportunistic pathogen. A study was done to determine the frequency of Cryptosporidium in immunosuppressed persons. METHODS Fecal samples were collected from Jinnah Postgraduate Medical Centre Karachi during July to December 2003 and they consisted of three categories of p...

INTRODUCTION Cryptosporidium is an important cause of diarrhea in children and immune-compromised individuals. Recent advances in molecular diagnostics have led to the discovery of subtype families that are thought to be more commonly associated with diarrhea. We aimed to isolate and characterize Cryptosporidium spp among children with diarrhea in Jos, Nigeria. METHODS Stool samples were coll...

BACKGROUND Cryptosporidium hominis and C. parvum are usually considered to be the major pathogens responsible for human cryptosporidiosis. However, there have been few studies regarding the molecular epidemiology of Cryptosporidium in human infections in China. Here we investigated Cryptosporidium infection in patients with diarrhea, in Danyang Hospital of Jiangsu Province, China, at the genoty...

OBJECTIVE To search for the opportunistic and other pathogenic intestinal parasites in dialysis patients, and to compare the methods used for diagnosis. METHODS This is a randomized study, which recruited participants from the dialysis patients. The study was carried out in the Department of Microbiology, Research Hospital, School of Medicine in Kocaeli University, Kocaeli, Turkey between Jun...

nisProtozoa from the phylum apicomplexa a associated with significant animal losses both pet and production systems. These ganisms can infect a wide range of verteb hosts, although many are host specific. The complexans of greatest interest to exotic pet p titioners are Isospora spp, Eimeria spp., Toxoplasma gondii, and Cryptosporidium spp. Historically, thes organisms have been very difficult ...

The objective of this study was to determine the prevalence, species and subtypes of Cryptosporidium infecting yaks in the Qinghai Province of Northwestern China. The prevalence of Cryptosporidium spp. was detected by microscopy and nested-PCR. A total of 586 fecal samples were collected from yaks in 6 counties, of which 142 (24.2%) samples tested positive for Cryptosporidium. The small subunit...

Five genera of potentially zoonotic bacteria and parasites were detected in environmentally collected fecal samples from a remote indigenous community in Northern Saskatchewan, Canada. Organisms identified include Toxocara canis, Echniococcus granulosus, Giardia duodenalis, Cryptosporidium spp., and Campylobacter spp. The prevalence and intensity of Giardia spp. and Campylobacter spp. in fecal ...

Cryptosporidium macropodum n. sp is described. Oocysts of C. macropodum from the feces of kangaroos (Macropus spp.) are morphologically indistinguishable from other mammalian Cryptosporidium species, including C. parvum, C. hominis, C. suis, and C. canis. The oocysts are fully sporulated on excretion, lack sporocysts, and have an average width of 4.9 microm (4.5-6.0), a length of 5.4 microm (5....

INDIAN PEDIATRICS 1161 VOLUME 42__NOVEMBER 17, 2005 Nitazoxanide (NTZ) is a novel broadspectrum antiparasitic agent originally discovered in 1980s by J.F. Rossignol. Nitazoxanide is effective in broad range of parasitic and protozoal infections including Giardia lamblia, Entamoeba histolytica, Cryptosporidium spp., Ascaris lumbricoides, Hymenolepis nana and Taenia solium/saginata. In combinatio...
