| clinical and biochemical significance of toxin production by aeromonas hydrophila. | production of cytotoxin and enterotoxin by aeromonas strains obtained from stools of 50 children in mexico and texas and from blood of 9 children with sepsis was determined. results were correlated with clinical features of infected children as well as with biochemical traits of aeromonas strains. cytotoxin was produced by 40 of 42 aeromonas strains (95%) isolated from stools of children with diarrhea, by all 8 isolates from stools of well children, and by all 9 isolates from children with sepsi ... | 1987 | 3584426 |

| incidence of bacterial enteropathogens in foods from mexico. | we examined food consumption patterns of u.s. students temporarily living in guadalajara, mexico. consumption of foods prepared in mexican homes was associated with an increased risk of acquisition of diarrhea. foods from commercial sources and private mexican homes in guadalajara were subsequently examined for contamination with coliforms, fecal coliforms, and bacterial enteropathogens. for comparison, selected restaurant foods were obtained in houston, tex. food obtained from mexican homes sho ... | 1983 | 6354085 |
| bacterial populations in the groundwater on the us-mexico border in el paso county, texas. | in el paso county, texas, 73 domestic wells were sampled using a variety of selective media to determine the extent of bacterial contamination of the groundwater on the us side of the united states-mexico border. thirteen wells were contaminated by fecal coliforms, whereas other wells contained a variety of bacterial genera including some potential pathogens that normally would not be detected by standard methods of water testing. | 1994 | 7973920 |
