摘要

本研究旨在进行大肠杆菌(E. coli)的表型和基因型鉴定,特别是从牛粪便中分离的VTEC菌株。本研究采用从奶牛和肉牛粪便标本和粪便基肥中分离得到的大肠杆菌25株。对大肠杆菌VTEC菌株进行表型和基因型鉴定。结果表明,新鲜粪便标本中检出VTEC菌株的比例为20%,粪便基肥样品中未检出VTEC菌株。在VTEC菌株中,VT1基因检出率为16%,VT2基因检出率为12%,两者检出率均为8%。肾盂肾炎相关pilli (pap)基因、S纤缘粘连(sfa)基因和纤缘粘连(afa)基因的检出率分别为60%、80%和80%。

DETEKSI GEN PENYANDI ADHESIN PADA VEROCYTOTOXIGENIC Escherichia coli (VTEC) ISOLAT SAPI (Detection of Gene Encoding Adhesin of Verocytotoxigenic Escherichia coli (VTEC) Isolated from Cattles)
This study was aimed to perform phenotypic and genothypic characterization of Escherichia coli (E. coli), particularly VTEC strain isolated from cattle faeces. In this study, 25 E.coli isolated from faeces specimens and faeces base fertilizer of dairy and beef cattles were used. Examination were carried out using phenotypic and genothypic characterization which is specified for E coli VTEC strain. The result showed that 20 % samples of fresh faeces specimens were detected as VTEC strains and none of isolate was detected from faeces base fertilizer samples. From VTEC strains, could detect 16 % VT1 gene, 12 % VT2 genes and 8% of both. Detection on gene pyelonephritis-associated pilli (pap), S fimbrial adhesion (sfa), and afimbrial adhesion (afa) were found about 60%, 80% and 80%, respectively.
