An outbreak of acute gastroenteritis hospitalized 99 (12%) of 835 U. S. Army trainees at Fort Bliss, El Paso, Texas, from August 27 to September 1, 1998. Reverse transcriptase polymerase chain reaction tests for Norwalk-like virus were positive for genogroup 2. Gastroenteritis was associated with one post dining facility and with soft drinks.
Small, round-structured viruses (SRSVs) detected from nonbacterial gastroenteritis outbreaks in Tokyo and Saitama Prefecture, Japan, during the period from 1977 to 1988 were tentatively classified into nine antigenic patterns from SRSV-1 (S-1) to SRSV-9 (S-9) by cross-immune electron microscopy (IEM). S-1 and S-2 appeared pattern specific, while S-3 to S-9, distinguishable from each other in th...
We report on recent advances in the study of critical points of the “black hole effective potential” VBH (usually named attractors) of N = 2, d = 4 supergravity coupled to nV Abelian vector multiplets, in an asymptotically flat extremal black hole background described by 2nV + 2 dyonic charges and (complex) scalar fields which are coordinates of an nV -dimensional Special Kähler manifold.
Noroviruses, an important cause of acute gastroenteritis in humans, recognize the histo-blood group antigens (HBGAs) as host susceptible factors in a strain-specific manner. The crystal structures of the HBGA-binding interfaces of two A/B/H-binding noroviruses, the prototype Norwalk virus (GI.1) and a predominant GII.4 strain (VA387), have been elucidated. In this study we determined the crysta...
Viral pollution in shellfish has been analyzed simultaneously across a wide range of geographical regions, with emphasis on the concomitant variations in physicochemical characteristics and social features. The methods for sample treatment and for the detection of human enteric viruses were optimized by the participating laboratories. The second part of this study involves the selection of a pr...
Cliver, D. O. 1988. Virus transmission via foods. Food Technol. 42:241-248. Viruses have emerged as causes of foodborne disease, according to data compiled by the Centers for Disease Control and Prevention. During 198387 in the United States, Norwalk virus was the fifth leading cause of foodborne disease among outbreak-associated illnesses; hepatitis A virus was the sixth; and other viruses ...
