acute cholecystitis and cholangitis caused by echinococcus granulosus.we report for the first time in the recent north american literature, the case of a patient with rupture of a hepatic hydatid cyst into the gallbladder, with subsequent obstruction of the cystic duct by a daughter cyst acting as a ball-valve and causing acute acalculous cholecystitis.19968677959
seroprevalence of seven zoonotic infections in nunavik, quebec (canada).in nunavik, common practices and food habits such as consumption of raw meat and untreated water place the inuit at risk for contracting zoonotic diseases. the aim of this study was to determine the seroprevalence of seven zoonotic infections among the permanent residents of nunavik. the study was conducted in the fall 2004 as part of the nunavik health survey. blood samples from adults aged 18-74ôçâyears (nôçâ=ôçâ917) were collected and analysed for the presence of antibodies against trichinell ...201121824376
the distribution of echinococcus granulosus in moose: evidence for parasite-induced vulnerability to predation by wolves?the role of parasites in influencing the trophic dynamics of hosts is becoming increasingly recognized in the ecological literature. echinococcus granulosus is a tapeworm that relies on the predator-prey relationship between the definitive host (wolf, canis lupus) and the intermediate host, (moose, alces alces) to complete its life cycle. heavy infection by e. granulosus may predispose moose to increased risk of predation by wolves. theory predicts that parasite-induced vulnerability to predatio ...200415232731
echinococcus granulosus (cestoda: taeniidae) infections in moose (alces alces) from southwestern quebec.investigation of the distribution of larval echinococcus granulosus in a moose population from southwestern quebec revealed a distinct and stable pattern of infection with a prevalence of 44% (n = 580). positive correlations between moose age and the intensity, mean cyst weight and biomass of the hydatid cysts suggested a process of continued parasite acquisition and cyst growth. the distribution of cyst sizes within individual moose provided circumstantial evidence of interaction between cysts, ...19873625899
seroprevalence of 10 zoonotic infections in 2 canadian cree communities.we evaluated the seroprevalence of 10 zoonotic agents among the general population (15 years old and over) of eastmain and wemindji, james bay, quebec, in 2007. overall seroprevalence rates were similar between the 2 communities. nearly half the individuals tested (n = 251; 146 women, 105 men) were seropositive (n = 115) for at least one zoonosis. the highest seroprevalence rates were for leptospira sp. (23%), francisella tularensis (17%), and the california serogroup viruses (jc and ssh viruses ...201121398073
seroprevalence of zoonoses in a cree community (canada).cree trappers and hunters are at risk for contracting infectious diseases conveyed by wildlife. we performed a study in a cree community (canada) to determine the seroprevalence of 8 zoonotic infections among hunters and trappers for evidence of exposure to trichinella sp., toxoplasma gondii, toxocara canis, echinococcus granulosus, leptospira sp., coxiella burnetii, francisella tularensis, and sin nombre virus. a total of 50 participants (28 women and 22 men) were included in this study. result ...200717878068
