| studies on virulence of shigella flexneri. protective effect of outer membrane proteins. | groups of mice were immunized intraperitoneally with proteins isolated from outer membrane of virulent strain of shigella flexneri 3a and its avirulent variant. all the animals were found to survive challenge with ld100 of virulent sh. flexneri 3a. similar protective effect against challenge with sh. flexneri 3a gave also immunization of mice with outer membrane proteins isolated from sh. flexneri of other serotypes (2a, 4a, 6, and x) and from escherichia coli, hafnia alvei and shigella sonnei. | 1981 | 7025793 |
| comparison of two methods for same-day identification of enterobacteriaceae. | two commercial methods, api 20e (as modified for same-day enterobacterial identification) and micro-id, were evaluated for ability to provide useful same-day information of 368 clinically isolated enterobacteriaceae. organisms included escherichia coli (54), shigella (7), edwardsiella tarda (1), salmonella enteritidis (10), citrobacter (30), klebsiella (55), enterobacter (68), hafnia alvei (2), serratia (33), proteus (64), morganella morganii (24), providencia (18), and yersinia enterocolitica ( ... | 1982 | 7051807 |
| a case with severe diarrhoea and strongyloides stercoralis infection. | a case with severe diarrhoea and strongyloides stercoralis infection is described. further examination showed that the patient also had abnormal colonization of the duodenum with hafnia alvei and that this disappeared when the strongyloides infection was treated with mebendazole. symptoms such as abdominal pain, diarrhoea, "skin rash" and malabsorption in association with blood eosinophilia should arouse suspicion of strongyloidiasis. | 1981 | 7234512 |
| aerobic bacterial oral flora of garter snakes: development of normal flora and pathogenic potential for snakes and humans. | garter snakes that are used for scientific laboratory studies or kept as exotic pets often become ill and die early in captivity. they may also act as reservoirs of potential human pathogens or transmit infection to man. a total of 126 strains of aerobic and facultative bacteria, most potential human and snake pathogens, were isolated from 82 garter snake oropharyngeal cultures. coagulase-negative staphylococcus species were the most common species isolated. acinetobacter calcoaceticus var. anit ... | 1981 | 7240404 |
| activity of a new cephalosporin antibiotic, ro 13-9904 against dense populations of selected enterobacteria. | ro 13-9904 is a new cephalosporin antibiotic with a wide spectrum of activity similar to that of cefotaxime and some other newer beta-lactam compounds. in the present study, the response to ro 13-9904 of 13 strains of enterobacteria, selected on the basis of differential patterns of susceptibility to beta-lactam agents, was investigated. the new cephalosporin displayed high intrinsic activity against most of the enterobacteria tested, but a group of klebsiella and hafnia alvei strains was identi ... | 1981 | 7247361 |
| attributes of microbial associations of meat growing as xenic batch cultures in a meat juice at 4 degrees c. | strains of gram-positive (carnobacterium piscicola, leuconostoc mesenteroides subsp. mesenteroides, brochothrix thermosphacta) and gram-negative (pseudomonas fragi and hafnia alvei) bacteria isolated from minced lamb packaged under a modified atmosphere were cultivated in a meat (lamb) juice at 4 degrees c. carbohydrates were catabolised in the order glucose > glucose 6-phosphate during the development of the population. under an atmosphere enriched with carbon dioxide the gram-negative portion ... | 1995 | 7488524 |
| characterization of hafnia alvei by biochemical tests, random amplified polymorphic dna pcr, and partial sequencing of 16s rrna gene. | hafnia alvei strains which possess the attachment-effacement gene (eaea) may have clinical importance as new diarrhea-causing pathogens and should therefore be differentiated from other h. alvei strains. we characterized diarrheal h. alvei strains, which were positive in the pcr test for the eaea gene, using biochemical tests not routinely used for identification of members of the family enterobacteriaceae, and compared them with eaea-negative strains isolated from different clinical and nonclin ... | 1995 | 7494030 |
