Abstract: Global warming and urbanization have brought wildlife and humans closer together.This study was conducted to survey potential risks of salmonellosis between wild birds and human.Bird fecal samples were collected from the wildlife medical center located on Nakdong Estuary Eco center in Busan, Korea (2022∼2023).In total, 9 Salmonella (S.) spp.(1.9%) belonged to 5 species from 467 samples by MALDI TOF MS identification and 2 serogroups and 6 serotypes were isolated.Serogroup B (78%) was the most common, followed by group C (22%).The major serotype was S. Typhimurium (44.4%:n=4), and S. Saintpaul, S. I,4,[5],12:i, S. Agona, S. Bareilly, and S. Infantis were isolated from 5 samples respectively (11.1%:n=1).There were summer visitors (56%:n=5), residents (33%:n=3), and only winter visitor (11%:n=1).Most cases appeared from May to September when mean temperature was above 20℃, except one case in January, winter.Antimicrobial susceptibility tests for 19 antibiotics were performed.The results revealed that all S. isolates were resistant to Cefalexin, Cefalotin, Amikacin and Gentamicin.The infected birds were considered to be asymptomatic carriers since most were rescued by collisions.The cases appeared to be similar climates to recent human salmonellosis.And isolated serogroups and serotypes were also similar to recent human salmonellosis in Korea.
