Abstract
|
|
|
As the number of international travelers worldwide increases, the importation of travel-related endemic diseases to new geographic areas is an important public health issue. And as a result, to secure foreign pathogens and related information through international base agencies, an international cooperation project for food-borne and water-borne disease was carried out on Laos in Southeast Asian countries.
This report was to examine the characteristics of Salmonella spp. collected in Laos from 2017 to 2019. The number of Salmonella spp. collected in Laos was 342 strains, and the gender ratio was similar to 52.9% for men and 47.1% for women. The age range was 0-5 years old (45.3%), and individual occurrences (96.8%) seemed to account for the majority rather than group occurrences (3.2%). There were a total of 33 serotypes, and the major serotypes were S. I 4,[5],12:i:- 18.0%, S. Rissen 12.1%, S. Stanley 12.1%, and S. Typhimurium 8.9% in order. the resistance rate of collected Salmonella to ampicillin or tetracycline was confirmed at 5% higher than that of domestic Salmonella, but strains resistant to cefotaxime or ciprofloxacin were rare.
And all Salmonella serotypes were characterized by pulsed field gel electrophoresis (PFGE). PFGE patterns of major Salmonella spp. isolates were classified in more than ten patterns. It is expected that the results of this study, will help prevent the premature diffusion of foreign pathogens by securing Salmonella epidemic pathogens and related information in South-east Asia, Furthermore, based on the findings of this study, continuous monitoring of pathogens is highly recommended.
