BACKGROUND Human cystic echinococcosis (CE) and alveolar echinococcosis (AE) are highly endemic in Tibetan communities of Sichuan Province. Previous research in the region indicated that domestic dog was the major source of human infection, and observations indicated that domestic dog could have more access to intermediate hosts of Echinococcus spp.: both domestic livestock (CE) viscera and sma...

BACKGROUND Taenia solium infections are mostly endemic in less developed countries where poor hygiene conditions and free-range pig management favor their transmission. Knowledge on patterns of infections in both human and pig is crucial to design effective control strategies. The aim of this study was to assess the prevalence, risk factors and spatial distribution of taeniasis in a rural area ...

Preservation of Cryptosporidium oocysts in faecal specimens containing 75% ethanol is suitable for subsequent morphometric and molecular analysis. No significant morphologic alteration occurred after storage at ambient temperatures, ranging from 22 to 38 degrees C, for more than 2 years. After washing, sugar floatation and DNA extraction, a nested polymerase chain reaction targeting the small s...

Scarabaeinae are sensitive to structural habitat changes caused by disturbance. We compared copronecrophagous beetle (Scarabaeinae) community structure in three differently managed zones within an agroeco-system of the northern Yucatan Peninsula, Mexico. We placed dung and carrion traps once a month from June 2004 through May 2005. The beetle community included 17 species from the genera Cantho...

BACKGROUND We aimed to evaluate different copro-preservation conditions along the duration of one month for a better outcome of molecular diagnosis of Cryptosporidium species. METHODS Ten samples out of 380 fresh stool samples collected from patients with diarrhea proved positive after direct examination, concentration, staining and confirmed by immunochromatographic test. The study was condu...

The study was conducted to know the copro-prevalence of hookworm infection in relation to various risk factors in the pet dogs from in and around Ludhiana. Total 250 dog faecal samples were examined by flotation and Mc Master egg counting technique for qualitative and quantitative evaluation, respectively. The prevalence of hookworms was correlated with meteorological data, age, sex and breed. ...

OBJECTIVE To determine molecular prevalence of Cryptosporidium in a cohort of Egyptian children and compare three diagnostic tests. METHODS Stool samples from children with diarrhea (n=150) and from apparently healthy children (n=100) were examined for Cryptosporidium using microscopy, enzyme linked immuosorbant assay (ELISA) and nested polymerase chain reaction (nPCR). RESULTS nPCR detecte...
