| shiga toxin-producing escherichia coli isolates from cases of human disease show enhanced adherence to intestinal epithelial (henle 407) cells. | shiga toxin-producing escherichia coli (stec) strains are a diverse group of organisms which are known to cause diarrhea and hemorrhagic colitis in humans. we have recently described a large food-borne outbreak of stec disease caused by contaminated semidry fermented sausage (a. w. paton, r. ratcliff, r. m. doyle, j. seymour-murray, d. davos, j. a. lanser, and j. c. paton, j. clin. microbiol. 34:1622-1627, 1996). stec strains belonging to several o serotypes were isolated from the contaminated f ... | 1997 | 9284155 |
| dna tests in prolific sheep from eight countries provide new evidence on origin of the booroola (fecb) mutation. | recent discoveries that high prolificacy in sheep carrying the booroola gene (fecb) is the result of a mutation in the bmpib receptor and high prolificacy in inverdale sheep (fecx(i)) is the result of a mutation in the bmp15 oocyte-derived growth factor gene have allowed direct marker tests to be developed for fecb and fecx(i). these tests were carried out in seven strains of sheep (javanese, thoka, woodlands, olkuska, lacaune, belclare, and cambridge) in which inheritance patterns have suggeste ... | 2002 | 12021074 |
