etiology and epidemiology of diarrheal diseases in the united states.accurate data on the frequency of acute diarrheal illness and the distribution of pathogens are not available for several reasons, including the facts that only a small fraction of cases come to the attention of physicians and that available diagnostic tests establish an etiology in only about half of these. in a survey of three groups of patients in a community (upper-middle class and lower class outpatients and hospitalized infants), a possible cause was found in fewer than 20 percent of outpa ...19853893118
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 ...19836354085
gram-negative enteric bacillary meningitis: a twenty-one-year experience.we reviewed our experience with gram-negative enteric bacillary meningitis in neonates and infants from 1969 through 1989. ninety-eight patients were identified. their ages were from 1 day to 2 years with a median of 10 days. in 25 patients (26%), predisposing factors were identified, the most common of which were neural tube defects and urinary tract anomalies. the causative agents were escherichia coli (53%), klebsiella-enterobacter species (16%), citrobacter diversus (9%), salmonella species ...19938419603
antimicrobial susceptibilities of aeromonas spp. isolated from environmental sources.aeromonas spp. are ubiquitous aquatic bacteria that cause serious infections in both poikilothermic and endothermic animals, including humans. clinical isolates have shown an increasing incidence of antibiotic and antimicrobial drug resistance since the widespread use of antibiotics began. a total of 282 aeromonas pure cultures were isolated from both urban and rural playa lakes in the vicinity of lubbock, texas, and several rivers in west texas and new mexico. of these, at least 104 were subseq ...200616950901
outbreaks of human enteric adenovirus types 40 and 41 in houston day care centers.human enteric adenovirus (ead) types 40 and 41 cause diarrhea in young children, but little is known about their association with outbreaks of diarrhea in the child care setting. this study evaluated ead as a cause of outbreaks of diarrhea among infants and toddlers in day care centers.19921313095
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.19947973920

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 ...19873584426
