BACKGROUND Mercury is a persistent, biomagnifying contaminant that can cause negative effects on ecosystems. Marshes are often areas of relatively high mercury methylation and bioaccumulation. Nelson's Sparrows (Ammodramus nelsoni) use marsh habitats year-round and have been documented to exhibit tissue mercury concentrations that exceed negative effects thresholds. We sought to further charact...

background: the intraperitoneal injection is a common method for establishing the experimental animal model infected with parasites. the aim of this study was to investigate if the intraperitoneal injection was another route of trichinella spiralis infection. methods:  from june to july 2015, twenty balb/c mice were intraperitoneally injected with 300 t. spiralis muscle larvae in department of ...

Repeated outbreaks of trichinellosis caused by the consumption of Trichinella-infected walrus (Odobenus rosmarus) meat, which have sometimes led to serious morbidity, have stimulated Inuit communities in Nunavik (northern Quebec), Canada, to develop an innovative trichinellosis prevention program. The program involves preconsumption testing of meat samples from harvested walrus at a regional la...

The clinical diagnosis of trichinellosis can be difficult due to lack of pathognomonic signs or symptoms. In Korea, since the first report of human infection by Trichinella spiralis in 1997 following the consumption of raw badger meat, there have been occasional trichinellosis outbreaks. We describe an outbreak of 12 cases of trichinellosis in Korea and implicate raw wild boar meat as the culpr...

Trichinellosis is a re-emerging zoonosis and more clinical awareness is needed. In particular, the description of new Trichinella species such as T. papuae and T. murrelli and the occurrence of human cases caused by T pseudospiralis, until very recently thought to occur only in animals, requires changes in our handling of clinical trichinellosis, because existing knowledge is based mostly on ca...

A method was developed to isolate and test coproantibodies from mice infected with Trichinella or mice fed cholera toxin. It was rapid as results were obtained within 3 h, and it was applicable to a single faecal pellet. It reduced the number of experimental animals required 7-fold, and reduced variability, since samples were obtained from the same experimental animal over time. As it was nonin...

Trichinellosis is a worldwide zoonotic disease caused by a nematode Trichinella spiralis. We studied a case of Trichinella spiralis infection with severe eye involvement, febrile condition, generalised malaise and muscular weakness in a young female patient. Comprehensive ophthalmologic, infectologic, neurological and immunologic examinations including electro diagnostic tests and CT scan of th...

The current paper summarizes the findings on endogenous morphine isolated by HPLC and characterized by mass spectroscopy in Schistosoma mansoni, Dracunculus medinensis and Ascaris suum. Morphine-6-glucuronide (M6G) has also been found by HPLC and confirmed by mass spectroscopy in Dracunculus medinensis and Ascaris suum. In addition, a morphine like substance has been isolated from Trichinella s...
