Abstract

This study compared the ambient air survival of two clinical strains of Mycobacterium tuberculosis that had caused significantly different numbers of cases in the same population. No difference in the survival ability between the two strains was found. However, a significant difference was observed in colony morphology between the two strains. These findings provide new insight into potential microbial determinants for the occurrence of large clusters of tuberculosis cases in a population.

摘要

本研究比较了在同一人群中引发病例数显著不同的两株临床结核分枝杆菌在环境空气中的存活情况。未发现两株菌在存活能力上存在差异。然而，观察到两株菌在菌落形态上存在显著差异。这些发现为人群中大量结核病例聚集发生的潜在微生物决定因素提供了新的见解。
