The most common Helicobacter pylori genotype among 37 U.S. children was cagA positive, vacA s1m1, and oipA "on" (n = 17, 45.9%), followed by cagA negative, vacA s2m2, and oipA "off" (n = 8, 21.6%), similar to the pattern in adults. cagA positivity was more common in blacks than in whites (i.e., 100% versus 56.5%, P = 0.032).
在美国 37 名儿童中,最常见的幽门螺杆菌基因型为 cagA 阳性、vacA s1m1 和 oipA“开启”(n = 17,45.9%),其次为 cagA 阴性、vacA s2m2 和 oipA“关闭”(n = 8,21.6%),与成人模式相似。cagA 阳性在黑人中比在白人中更为常见(即 100%比 56.5%,P = 0.032)。
