A group of pandemic strains of Vibrio parahaemolyticus has recently appeared in Asia and North America. We demonstrate that a filamentous phage is specifically associated with the pandemic V. parahaemolyticus strains. An open reading frame unique to the phage is a useful genetic marker to identify these strains.
To study the association of multidrug-resistant enteroaggregative Escherichia coli with persistent diarrhea in Kenyan children, stool specimens were obtained from 862 outpatients under 5 years of age from July 1991 to June 1993. E. coli O44 was identified as the sole bacterial pathogen in four patients experiencing at least 14 days of fever, vomiting, and… (More)
— In this paper, we propose a blind frame-by-frame dereverberation using correlation coefficients considering peri-odicity of voiced speech. In the proposed method, the reference signal is derived by reducing speech periodicity from recovered signal of previous frame. The reference signal is used in order to estimate the impulse response in each frame. The… (More)
