Isolation of Hemagglutinative Non-el Tor Cholera Vibrios.
During 1963, El Tor cholera spread through Thailand and Burma, and finally appeared in the Chittagong area of East Pakistan in November (Yen et al., East Pakistan MIed. J. 8:22, 1964). With disease caused by the El Tor vibrio within 80 km of areas under study by this laboratory, all vibrio isolates which agglutinated in cholera antisera were screened by the chicken erythrocyte agglutination tes...
متن کاملPreselection of hemolytic variants of el tor vibrios.
Historically, hemolytic activity in tube tests was regarded as the sine qua non in the differentiation of El Tor from classical cholera vibrios. However, in the recent outbreaks of cholera in Southeast Asia, many strains of agglutinable vibrios have been isolated which share a large number of properties ascribed to El Tor vibrios (and not the classical variety), but which lack hemolytic activit...
متن کاملUse of colistin-polymyxin B-cellobiose agar for isolation of Vibrio vulnificus from the environment.
Colistin-polymyxin B-cellobiose agar was employed for the isolation of Vibrio vulnificus from shellfish. Isolates were examined phenotypically and with a gene probe and monoclonal antibody specific for V. vulnificus. Results indicated that colistin-polymyxin B-cellobiose agar is superior to both sodium dodecyl sulfate-polymyxin B-sucrose agar and thiosulfate-citrate-bile salts-sucrose agar in i...
متن کاملEnhancement by sodium chloride of the selectivity of thiosulfate citrate bile salts sucrose agar for isolating Vibrio cholerae biotype El Tor.
In this study we utilized the salt-tolerant characteristics of vibrios to develop a more selective medium by addition of NaCl to thiosulfate citrate bile salts sucrose (TCBS) agar. The effect of adding salt to TCBS agar varied greatly among brands of TCBS agar and between lots of the same brand. The addition of salt at concentrations as high as 1.5% (2.5% total NaCl) caused the inhibition of gr...
متن کاملTransition of drug susceptibilities of Vibrio cholerae O1 in Lao People's Democratic Republic.
The changes of drug susceptibilities of Vibrio cholerae O1 isolated during the past 7 years (1993-1999) in Lao PDR were investigated. The most noteworthy finding was the appearance of polymyxin B sensitive El Tor vibrios. Until 1996, the susceptibilities were almost as expected and cholera disappeared in 1997. When a cholera outbreak resurfaced in 1998, the susceptibilities of isolated V. chole...
