| isolation of medically significant vibrio species from riverine sources in south east queensland. | vibrio and vibrio-like bacteria were isolated from water, sediments, plants and faeces from eight riverine sites in south east queensland, australia, using filtrations, enrichments and selective growth on thiosulphate-citrate-bile salts-sucrose (tcbs) and simidu agars. isolates (402 in toto) were classified by numerical analysis of phenotypic characteristics and comparison with fifteen reference cultures. of the isolates 41 (10.2%) were identified as vibrio cholerae, 33 (8.2%) as v. fluvialis an ... | 1989 | 2607994 |
| investigation of cholera acquired from the riverine environment in queensland. | since february 1977, five patients with cholera apparently acquired the infection from the riverine environment in queensland. a total of 13 rivers have now yielded at least one isolate of vibrio cholerae 01 biovar el tor. investigations indicate that the organism, including toxigenic strains, can survive and multiply in the riverine environment. no human or animal reservoirs and no ecological niches were identified and no route of importation or dissemination of the organism was discovered. the ... | 1986 | 3587092 |
| the queensland cholera incident of 1977. 2. the epidemiological investigation. | in 1977 the first case of cholera known to be contracted in australia during the seventh pandemic occurred in southeastern queensland. toxigenic isolates of vibrio cholerae, biotype eltor, serotype inaba, phage-type 2, were obtained from the index case, a companion of the patient, the reticulated water supply of their place of residence, and a stretch of the neighbouring river that was being used to supplement fully treated water piped from brisbane. treatment of the auxiliary supply consisted s ... | 1980 | 6969139 |
| detection of heat-stable enterotoxin genes among australian vibrio cholerae o1 strains. | dna probes derived from the heat-stable enterotoxin gene of vibrio cholerae non-o1 (stn), and the cholera toxin gene (ctx), were used to screen 199 strains of v. cholerae o1, which were isolated within australia from 1977-1986. 13 environmental strains isolated from the riverine environment in southeast queensland in 1980 and 1981, hybridized with the stn and ctx dna probes. the concentrated supernatant of 6 of these strains elicited fluid accumulation in the infant mouse assay both before and a ... | 1995 | 7737472 |
| vibrio cholerae non-o1 facial cellulitis in a north queensland, australian child. | vibrio cholerae is an uncommon cause of cellulitis in australia. most reported cases worldwide have involved marine or brackish water contact. a recognized risk factor for acquiring this infection is chronic liver disease secondary to hepatitis b. we describe a case of extensive facial cellulitis caused by vibrio cholerae non-o1, non-0139, in an 11-year-old indigenous girl from north queensland, australia, who was hepatitis b surface antigen-negative. treatment consisted of extensive debridement ... | 2001 | 11368121 |
| distribution of 19 major virulence genes in legionella pneumophila serogroup 1 isolates from patients and water in queensland, australia. | the distribution of 19 major virulence genes and the presence of plasmids were surveyed in 141 legionella pneumophila serogroup (sg) 1 isolates from patients and water in queensland, australia. the results showed that 16 of the virulence genes examined were present in all isolates, suggesting that they are life-essential genes for isolates in the environment and host cells. the 65 kb pathogenicity island identified originally in strain philadelphia-1(t) was detected more frequently in isolates f ... | 2006 | 16849718 |
