Some authors have reported a relationship between the 4G/4G homozygous genotype with insulin resistance and increased adipose tissue in Caucasian populations, where the 4G allele is considered the risk allele, since it has been associated with high PAI-1 levels due to the lack of a binding site for a transcriptional repressor gene (30).
Of the tested specimens, 34 isolates carried the tcpA gene, encoding the structural subunit of toxin-coregulated pilus, and the rstR gene, the repressor gene in the cholera toxin encoding (CTX) phage (3); these results may indicate that these strains belonged to the El Tor biotype.
