Our method for information retrieval uses Robertson's 2-poisson model which is one type of probablistic approach. This method achieved a comparatively high score in TREC. In the NTCIR contest, we designed systems that could be used for adhoc retrieval and cross-lingual task. This paper explains the systems. key words 2-poisson model, adhoc retrieval, cross lingual retrieval G °±ê+HKsÞð ·Ù À U ...

BACKGROUND The rate of infection with Clostridium difficile colitis and its associated mortality have been increasing in the last decade. The molecular epidemiology of C. difficile in Israel has not been studied. OBJECTIVES To screen for the existence of the 027 and 078 ribotypes and determine the longitudinal molecular epidemiology of the circulating clinical C. difficile isolates in a large...

BACKGROUND Clostridium difficile is an important bacterial pathogen of humans and a variety of animal species. Birds, especially migratory passerine species, can play a role in the spread of many pathogens, including Clostridium difficile. Barn Swallows (Hirundo rustica) nest in close proximity to human habitats and their biology is closely associated with cattle farming. Therefore, we hypothes...

There has been an increase in community-associated Clostridium difficile infections with biosolids derived from wastewater treatment being identified as one potential source. The current study evaluated the efficacy of thermophilic digestion in decreasing levels of C. difficile ribotype 078 associated with sewage sludge. Five isolates of C. difficile 078 were introduced (final density of 5 log ...
