A total of 201 wild geckos from the region of Mekong Delta, Vietnam were collected to determine the viable number and survival period of Salmonella in their feces. Of the 101 samples examined, 24 (23.8%) were Salmonella positive. These 24 geckos excreted Salmonella in their feces in a range of 1 to 8.6 log CFU/g with a mean of 4.5 ± 3.2 log CFU/g. Among the Salmonella serovars, Salmonella Weltevreden was the most predominant serovar (37.5%). Moreover, Salmonella could survive for 6 weeks in gecko feces at room temperature in Vietnam. These results indicate that the wild gecko seems to play an important role as a reservoir for Salmonella and a source of Salmonella infection in humans in Southeast Asian countries.
总共收集了201只来自越南湄公河三角洲地区的野生壁虎，以确定沙门氏菌在其粪便中的存活数量和存活期。在检测的101个样本中，24个（23.8%）沙门氏菌呈阳性。这24只壁虎粪便中排出的沙门氏菌数量在1至8.6 log CFU/g之间，平均为4.5±3.2 log CFU/g。在沙门氏菌血清型中，韦尔特弗里德沙门氏菌是最主要的血清型（37.5%）。此外，在越南室温条件下，沙门氏菌可在壁虎粪便中存活6周。这些结果表明，野生壁虎似乎作为沙门氏菌的宿主以及东南亚国家人类沙门氏菌感染源发挥着重要作用。
