Abstract
Outbreaks Caused by New Variants of<i>Vibrio cholerae</i>O1 El Tor, India
Highlights
Streptococcus suis meningitis: first case reported in Quebec
To the Editor: Vibrio cholerae O1, the causative agent of cholera, has 2 biotypes, which have traditionally been distinguished by phenotypic tests and by genetic differences in the major toxincoregulated pilus (TCP) gene, the tcpA allele of the TCP cluster (1), the rstR region of CTX phages (2), the type of cholera toxin (CT) produced, and the infection pattern of the disease they cause
CT, encoded by the ctxA and ctxB genes, is the principal toxin produced by V. cholerae O1 and O139
Summary
Streptococcus suis meningitis: first case reported in Quebec. Letters reporting cases, outbreaks, or original research should contain no more than 800 words and 10 references. To the Editor: Vibrio cholerae O1, the causative agent of cholera, has 2 biotypes (classical and El Tor), which have traditionally been distinguished by phenotypic tests and by genetic differences in the major toxincoregulated pilus (TCP) gene, the tcpA allele of the TCP cluster (1), the rstR region (regulatory region for phage lysogeny) of CTX phages (2), the type of cholera toxin (CT) produced, and the infection pattern of the disease they cause.
