The study was intended to analyse the burden of Clostridium difficile (C. difficile) and associated intestinal pathogens from children with diarrhoea who were hospitalized in a tertiary care teaching hospital of South India.
Stool samples from 138 children with diarrhoea belonging to the age group 0-14 years were analysed by semi quantitative culture, latex agglutination and enzyme immunoassay for C. difficile. The associated intestinal pathogens were also detected from the specimens by standard procedures.
Stool samples of 138 children were tested during the period; 21 (15.22%) samples were culture positive for C. difficile and the isolates were confirmed by biochemical reactions. 9(6.52%) were positive by latex agglutination. EIA for C. difficile toxins A and B was done on all the stool specimens and 15 were found to be positive (10.87 %). According to the reference standard method employed in our study, 4 toxigenic C. difficile isolates (2.90%) were obtained from 138 specimens. Among the other intestinal pathogens, Escherichia coli predominated (22.46%). Rota virus was detected in 7.27% stool samples of children under the age of five years.
The study shows the prevalence of C. difficile in hospitalized children in our locality which highlights the importance of judicious use of antibiotics and strict infection control measures.
本研究旨在分析在印度南部一家三级护理教学医院住院的腹泻儿童中艰难梭菌及相关肠道病原体的负担情况。
对138名年龄在0至14岁的腹泻儿童的粪便样本进行艰难梭菌的半定量培养、乳胶凝集试验和酶免疫测定分析。还通过标准程序从标本中检测相关肠道病原体。
在此期间对138名儿童的粪便样本进行了检测;21份(15.22%)样本艰难梭菌培养呈阳性,分离株通过生化反应得以确认。9份(6.52%)乳胶凝集试验呈阳性。对所有粪便标本进行了艰难梭菌毒素A和B的酶免疫测定,发现15份呈阳性(10.87%)。根据我们研究中采用的参考标准方法,从138份标本中获得了4株产毒艰难梭菌分离株(2.90%)。在其他肠道病原体中,大肠杆菌占主导(22.46%)。在5岁以下儿童的7.27%粪便样本中检测到轮状病毒。
该研究表明了我们当地住院儿童中艰难梭菌的流行情况,这突出了合理使用抗生素和严格感染控制措施的重要性。
