The survival of strains of Campylobacter jejuni and enteropathogenic and enterotoxigenic (LT) Escherichia coli was investigated in mahewu, a traditional fermented cereal gruel. The mahewu was inoculated with 10(6) to 10(7) colony forming units of the bacterial cells per ml of the cereal gruel. None of the strains of C. jejuni were detected 30 min after inoculation. All the strains of E. coli were detected after 24 h in mahewu but did not show any increase in numbers of surviving cells. The enterotoxigenic E. coli strains showed a more marked decrease in numbers than did enteropathogenic E. coli strains during the 24 h period after inoculation in the mahewu. This suggests that mahewu has some antimicrobial qualities and is unlikely to play a major role in the transmission of these 2 enteric pathogens.
对空肠弯曲菌以及肠致病性和产肠毒素性（LT）大肠杆菌菌株在传统发酵谷物粥“mahewu”中的存活情况进行了研究。每毫升谷物粥接种10⁶至10⁷个细菌细胞集落形成单位的这些菌株。接种后30分钟未检测到空肠弯曲菌菌株。所有大肠杆菌菌株在mahewu中24小时后被检测到，但存活细胞数量未显示出任何增加。在接种到mahewu后的24小时内，产肠毒素性大肠杆菌菌株数量的减少比肠致病性大肠杆菌菌株更明显。这表明mahewu具有一些抗菌特性，不太可能在这两种肠道病原体的传播中起主要作用。
