BACKGROUND
Although the pathogenesis of is well-defined, the origin and transmission of the bacterium have remained largely unknown. The water transmission hypothesis suggested that water acts as a carrier in oral-fecal transmission, especially in high-prevalence areas. We aimed to evaluate the possible contamination of tap water with infective in Kermanshah, Iran from Sep-Oct 2020.
METHODS
Tap water samples were collected from varieties of probable high-alert regions and the viability of were achieved using culture and real-time PCR techniques ( gene expression).
RESULTS
Out of 50 tap water samples, 3 were positive for before enrichment and 6 were positive after enrichment by RT qPCR, while colonies of two samples were observed on brucella agar plates.
CONCLUSION
The results of positive samples demonstrated the probable presence of viable in tap water samples, showing that tap water distribution systems could be a potential route for transmission.
背景
尽管[细菌名称]的发病机制已明确，但该细菌的起源和传播在很大程度上仍不清楚。水传播假说表明，水在粪口传播中充当载体，尤其是在高流行地区。我们旨在评估2020年9月至10月伊朗克尔曼沙赫市自来水可能被感染性[细菌名称]污染的情况。
方法
从各种可能的高警戒区域采集自来水样本，并使用培养和实时PCR技术（[细菌名称]基因表达）检测[细菌名称]的生存能力。
结果
在50份自来水样本中，富集前3份样本经RT qPCR检测[细菌名称]呈阳性，富集后6份样本呈阳性，同时在布鲁氏菌琼脂平板上观察到两份样本有[细菌名称]菌落。
结论
阳性样本结果表明自来水中可能存在有生存能力的[细菌名称]，这表明自来水分配系统可能是[细菌名称]传播的一个潜在途径。
