Echinococcosis and hydatidosis is a parasitic zoonotic disease of human and animals. This disease has created public health and environment problems in all urban areas of Nepal. Based on the three year study (1993-1995) it has been revealed that the epidemiological cycle (indigenous) of Echinococcus granulosus parasite is dog-pig-dog cycle and human acquire infection accidentally through infect...

Background: Cryptosporidium is a protozoan parasite with worldwide distribution mainly affecting children and HIV infected individuals with low CD4 counts. The infection is self limiting in immunocompetent hosts but can be severe and persist in the immunocompromised and malnourished individuals. The aim of this study was to estimate the prevalence of Cryptosporidium infection in faeces among im...

Human dicrocoeliosis is reported sporadically in various parts of the world. We report a case in a 21-year-old male, who had right upper abdominal pain, weight loss, and chronic relapsing watery diarrhea three to four times daily for four weeks. The patient had abdominal tenderness to palpation in the right upper quadrant. Alkaline phosphatase, alanine aminotransferase, and serum immunoglobulin...

C. philippinensis is a parasite of the small intestine that causes a severe enteropathy and at times death in cases of delayed diagnosis or inappropriate treatment. This study aims to detect the molecular prevalence of C. philippinensis among diarrheic patients at Beni-Suef, Egypt. Stool samples were collected from 121 diarrheic patients and subjected to copro-parasitological examination and co...

A multiplex real-time PCR assay for the detection and quantification of Schistosoma mansoni and S. haematobium DNA in faecal samples was developed and evaluated as an alternative diagnostic method to study the epidemiology of schistosomiasis. Primers and probes targeting the cytochrome c oxidase gene were designed for species-specific amplification and were combined with an internal control. Us...

BACKGROUND AND PURPOSE Cryptosporidium is a protozoan parasite that reproduces within the epithelial cells of several organs of vertebrate hosts. The manifestation of the disease is either self-limiting acute diarrhea in immunocompetent patients, or fatal chronic diarrhea in immunocompromised patients. Common clinical symptoms include watery diarrhea, abdominal pain, and weight loss. METHODS ...

Eleitamoeba histolytica is now known to consist of two genetically distinct yet morphologically identical species, the invasive pa・rasite, retaining the name Entamoeba histolvtica Schaudinn, 1903, separating it from the noninvasive parasite, Entamoeba disPar Brumpt, 1925 [1]. In view of.this recent development in amebiasis research, there is a great need to reassess preyiously reported prevalen...

Two cases of unsuspected Strongyloides stercoralis infection were elucidated by the displacement of bacterial colonies on primary plating media. Observation of primary plates inoculated for the diagnosis of bacterial pneumonia or gastroenteritis revealed that normal flora colonies had been moved and were aligned in a pathway, or track. This unusual colony alignment prompted us to request a stoo...

Introduction: Blastocystis hominis is a parasite found in the stools of human as well as in the stools of other animals and recently its pathogenic potential has been increasingly recognized. Irritable Bowel Syndrome (IBS) is a digestive system’s disorder which is featured by change in bowel habits, abdominal pains and other symptoms similar to Blastocystis hominis infection. There is lit...
