| a study of the bacterial and parasitic causes of acute diarrhoea in northern jordan. | the prevalence of bacterial and parasitic diarrhoeagenic agents in 200 patients suffering from acute diarrhoea and reporting to hospitals and health centres in northern jordan, and in controls was determined. one or more bacterial or parasitic enteropathogens was isolated from 79 patients (39.5%). prevalence rates for these pathogens was as follows: enterotoxigenic escherichia coli, 9%; enteropathogenic e. coli, 9%; salmonella spp. 7%; campylobacter spp, 5.5%; yersinia enterocolitica, 4.5%; shig ... | 1991 | 1800560 |
| structure of the rabbit phospholamban gene, cloning of the human cdna, and assignment of the gene to human chromosome 6. | we have isolated and characterized genomic dna clones encoding rabbit phospholamban. only a single gene for phospholamban was detected in the rabbit genome. the phospholamban gene of 13.2 kilobases contains only one 10.5-kilobase intron, which separates exonic sequences located in the 5'-untranslated region. two potential transcription initiation sites were mapped to 335 and 185 nucleotides upstream from the translation initiation site in the mrna or 239 and 89 nucleotides upstream from the exon ... | 1991 | 1828805 |
| iron uptake in plesiomonas shigelloides: cloning of the genes for the heme-iron uptake system. | the iron uptake systems of plesiomonas shigelloides strains were determined. siderophore production was not detected by chemical or biological assays, and the strains tested were unable to use enterobactin, aerobactin, or vibriobactin for growth in low-iron media. both hemin and hemoglobin supported full growth of the bacteria in media lacking other iron sources, but neither transferrin nor lactoferrin served as a source of iron. hemolysin was detected, and the production of hemolysin was iron r ... | 1991 | 1830293 |
| evidence that the asparagine 322 mutant of the lactose permease transports protons and lactose with a normal stoichiometry and accumulates lactose against a concentration gradient. | the single asparagine 322 mutant of the lactose permease was made by constructing a hybrid plasmid which contained the amino-terminal coding sequence from the wild-type permease gene and the carboxyl-terminal coding sequence from a previously characterized double mutant permease which contained an asparagine residue at position 322. since histidine at position 322 has been postulated to be critically involved with h+ transport and the active accumulation of sugars, the ability of the asn-322 mut ... | 1991 | 1849889 |
| aeromonas and plesiomonas as food- and waterborne pathogens. | aeromonas and plesiomonas have become increasingly recognized as human enteropathogens. plesiomonas shigelloides has mainly been recovered from various sea foods, whereas aeromonas sp. have also been cultured from pigs, broilers, eggs, milk and vegetables. aeromonas sp. also multiply rapidly at +4 degrees c which is a significant risk in food storage. aeromonas sp. have furthermore been recovered from fresh water sources, and some isolates are resistant to chlorination which makes it a further r ... | 1991 | 1854599 |
| multilocus genetic relationships between clinical and environmental aeromonas strains. | allelic variations in the chromosomal genome of 120 isolates of motile aeromonas (a. hydrophila, a. sobria and a. caviae) and eight reference strains with one plesiomonas shigelloides were assessed by analysis of electrophoretically demonstrable polymorphism in 16 genes encoding metabolic enzymes. the strains were collected from humans (n = 59) and from the aquatic environment (n = 61) in canton tessin, switzerland. clustering of the electrophoretic types (et) from a matrix of pairwise genetic d ... | 1991 | 1884994 |

| acidity and intestinal bacteria: an in-vitro assessment of the bactericidal activity of hydrochloric acid on intestinal pathogens. | the bactericidal activity of hydrochloric acid (hcl) on different intestinal bacteria was evaluated at various ph values and time intervals. the effect of hcl was highest at ph 2 and ph 3 on strains of campylobacter jejuni, aeromonas hydrophila, plesiomonas shigelloides, yersinia enterocolitica, salmonella spp. and shigella spp., producing complete killing after 60 min incubation. however, at higher ph values (ph 4 and above), these organisms not only survived but they also showed evidence of ra ... | 1990 | 2127996 |
| plasmid screening amongst aeromonas species and plesiomonas shigelloides isolated from subjects with diarrhoea in lagos, nigeria. | fifty-three aeromonas strains and 16 plesiomonas shigelloides isolated from subjects with diarrhoea in lagos were screened for the presence of plasmids. nine (17%) of the aeromonas strains and one (6.3%) of the p. shigelloides harboured one or more plasmids, ranging in size from 2.4 to 16.8 mda. as has been documented in other enteropathogens, the possibilities are that these plasmids code for some factors to enhance the virulence of their hosts. | 1990 | 2128001 |
