| three cases of hemorrhagic colitis in west virginia due to escherichia coli o157:h7. | escherichia coli o157:h7 is an emerging cause of food-borne illness. this bacterial pathogen, most commonly transmitted by undercooked ground beef, causes hemorrhagic colitis. it has been associated with the hemolytic uremic syndrome and death, mostly in children and the elderly. this article describes three patients treated for sporadic cases of escherichia coli o157:h7-associated hemorrhagic colitis at charleston area medical center over a three-week period. | 1995 | 8533400 |

| a multistate outbreak of escherichia coli o157:h7 infections linked to alfalfa sprouts grown from contaminated seeds. | a multistate outbreak of escherichia coli o157:h7 infections occurred in the united states in june and july 1997. two concurrent outbreaks were investigated through independent case-control studies in michigan and virginia and by subtyping isolates with pulsed-field gel electrophoresis (pfge). isolates from 85 persons were indistinguishable by pfge. alfalfa sprouts were the only exposure associated with e. coli o157:h7 infection in both michigan and virginia. seeds used for sprouting were traced ... | 2001 | 11747724 |
| detection of salmonella strains and escherichia coli o157:h7 in feces of small ruminants and their isolation with various media. | salmonella strains and escherichia coli o157:h7 were detected in 17 and 5 small ruminants in virginia, respectively, of 287 tested. background microflora interfered with the fecal analysis. the combination of salmonella enzyme immunoassay (eia) detection and xylose-lysine-deoxycholate agar isolation was satisfactory. modifying enrichment to a 1:100 dilution enabled effective e. coli o157:h7 detection by eia and isolation by sorbitol-macconkey agar with cefixime-tellurite. | 2005 | 15812051 |
| comparison of the microbial quality of ground beef and ground beef patties from internet and local retail markets. | this study evaluated the microbial quality of ground beef and ground beef patties sold at local (virginia) and internet (u.s.) retail markets. a total of 152 ground beef products, consisting of locally purchased raw ground beef (lrg) and frozen beef patties (lfp) and internet-procured frozen ground beef (ifg) and frozen beef patties (ifp), were tested. results showed that lfp had significantly lower levels of aerobic mesophiles, psychrotrophs, and coliforms than lrg, ifg, and ifp. furthermore, i ... | 2009 | 19722408 |
