There is continuing interest in identifying Helicobacter pylori virulence factors that might predict the risk for symptomatic clinical outcomes. It has been proposed that iceA and cagA genes are such
The diversity of the cytotoxin-associated gene (cagA) of Helicobacter pylori was analyzed in 45 isolates obtained from nine countries. We examined variation in the 5′ end of the cagA open reading fram
Incomplete cagA = cagA and cag empty site were not detected.Incomplete vacA = either vacA s or vacA m regions were not detected (4/10 vacAs1 was detected & vacAm was missing, 2/10 vacAs2 detected and
