Abstract

Between January to October 1991, were studied 148 samples of feces corresponding to the same number of children with acute diarrhea. In 41 (27.7%) samples, were found macroscopic or microscopic blood. At least one associated bacterial pathogen capable to produce bloody diarrhea was isolated from 22 (53.7%) of these samples. Were isolated five (12.2%) Salmonella strains, all of them were S. enteritidis; nine (22.0%) Shigella: seven S. flexneri, one S. boydii, and other one S. sonnei; two (4.9%) enteroinvasive Escherichia coli strains, and six (14.6%) Campylobacter jejuni strains. A single associated invasive bacterial pathogen was isolated in 13 (31.7%) children. Mixed culture were found in nine children: five (12.2%) children had invasive pathogens association, and four (9.8%) children had invasive and no invasive pathogens association.

摘要

1991年1月至10月期间，对148份粪便样本进行了研究，这些样本来自相同数量的急性腹泻儿童。在41份（27.7%）样本中发现了肉眼可见或显微镜下可见的血液。从这些样本中的22份（53.7%）中分离出至少一种能够引起血性腹泻的相关细菌病原体。分离出5株（12.2%）沙门氏菌菌株，均为肠炎沙门氏菌；9株（22.0%）志贺氏菌：7株福氏志贺氏菌、1株鲍氏志贺氏菌和1株宋内志贺氏菌；2株（4.9%）肠侵袭性大肠杆菌菌株，以及6株（14.6%）空肠弯曲菌菌株。13名（31.7%）儿童中分离出单一相关侵袭性细菌病原体。在9名儿童中发现混合培养：5名（12.2%）儿童有侵袭性病原体关联，4名（9.8%）儿童有侵袭性和非侵袭性病原体关联。
