Abstract
|
|
|
Salmonella is a common pathogen causing water- and foodborne diseases worldwide. This pathogen typically spreads
through contaminated water and food. Infection outbreaks are typified by main symptoms including diarrhea, fever, chills,
and vomiting. We analyzed the prevalence and characteristics of Salmonella strains isolated from the Enteric Pathogens
Active Surveillance Network (Enter-Net) from 2019 to 2021. A total of 1,872 Salmonella strains were isolated from domestic
residents (1,789 strains) and returning travelers (83 strains) in Korea using Enter-Net. The identified Salmonella strains showed 100 serotypes, the most common being Salmonella Enteritidis 379 (20.2%), Salmonella Typhimurium 357 (19.1%), and Salmonella I 4,[5],12:i:- 301 (16.1%), most of which were caused by Salmonella Enteritidis and Salmonella Typhimurium. The imported strains were isolated from patients with diarrhea who returned from the Philippines, Vietnam, China, Thailand, and Indonesia. Indentified serotypes, such as Salmonella Newport, Salmonella Anatum, Salmonella Stanley and Salmonella Derby, of imported strains showed a higher isolation rate than serotypes of domestic strains. Three serotypes, Salmonella Amagar, Salmonella Duesseldorf, and Salmonella Kottbus, have never been isolated in Korea. The results of monthly isolation rate showed that the risk of Salmonella infection increases from March to October, and it is necessary to prevent and manage food poisoning outbreaks, with particular focus in warmer seasons. This study aimed to provide information on the distribution of the prevalent Salmonella serotypes isolated from patients with diarrhea over the past 3 years through the national pathogen monitoring system, for addressing and preventing outbreaks of infectious diseases.
