Isolation of Vibrio cholera El Tor Inaba From Lemna minor and Eichhornia crassipens Roots in Veracruz, Mexico

BACKGROUND During epidemic periods, the strain Vibrio cholera El Tor has been isolated from the aquatic macrophyte roots of Eichhornia crassipens and Lemna minor, suggesting that aquatic plants could be environmental reservoirs through either a non-specific association or a commensalism relationship. Therefore, it is important to understand V. cholera reservoirs in order to establish prevention...

Spread of cholera with newer clones of Vibrio cholerae O1 El Tor, serotype inaba, in India.

During 2004 and 2005, cholera was recorded in 15 states of India, with 7 outbreaks. The newly emerged Vibrio cholerae O1 Inaba had a different antibiogram and ribotype, different pulsotypes, and different mutations in the wbeT gene. Due to the absence of serogroup O139, the Inaba serotype may have acquired the potential to affect the population at large.

Emergence of Vibrio cholerae O1 biotype El Tor serotype Inaba causing outbreaks of cholera in Orissa, India.

A total of 431 rectal swabs, collected from acute diarrheal cases at a surveillance site and at different diarrheal outbreak areas of Orissa from May to October 2005, were bacteriologically analyzed. Out of 265 culture-positive samples, Vibrio cholerae O1 was isolated in 56 samples (20.8%), of which 37 were the Inaba serotype and 19 were the Ogawa. The antibiogram profile revealed that all the ...

Nontoxigenic Vibrio cholerae 01 serotype Inaba biotype El Tor associated with a cluster of cases of cholera in southern India.

Thirteen strains of Vibrio cholerae 01 belonging to the Inaba serotype El Tor biotype isolated from patients during an outbreak of cholera in the town of Warangal in southern India were found to be nontoxigenic (NT), since they did not produce cholera toxin or hybridize with DNA probes specific for cholera toxin, Zot, or Ace. The unheated and heated culture supernatants of the NT V. cholerae 01...

Technical considerations of cholera vaccines and some results of cholera - El-Tor mass immunization

Emergence of Vibrio cholerae O1 Biotype El Tor serotype Inaba in north India.

All cases of cholera that have occurred at our center in north India have been due to Vibrio cholerae O1 serotype Ogawa, including the outbreaks in 2002 and 2004. Here we report the emergence of V. cholerae O1 biotype El Tor serotype Inaba for the first time in this region since July 2004. Fifteen Inaba isolates were obtained from 32 patients suffering from cholera-like illness. The patients li...
