Two pediatric cases of Salmonella Poona gastroenteritis with bacteremia in Japan

Kunio MURAKI1,3), Yoshiki KUSAMA2)

Salmonella Poona is a serotype non-typhoidal Salmonella (NTS). It has been isolated from various reptiles and tends to cause bacteremia more frequently than other NTS serotypes. This study reported two pediatric cases of bacteremia due to S. Poona. Case 1: a six-year-old girl presented persistent fever and diarrhea to this hospital. She had played in a river two days prior to clinical onset. S. Poona was isolated from her blood culture. After 14 days of ceftriaxone administration, she recovered without any complications. Case 2: a one-year-old boy was referred to this hospital with fever, diarrhea, and a positive blood culture of Salmonella species. Although he had no history of having direct contact with reptiles, the nursery he belonged to had turtles for pets. S. Poona was detected by blood culture. After seven days of ceftriaxone administration, and subsequently, seven days of oral amoxicillin administration, he recovered without any complications. Although NTS is thought to be caused by food poisoning from raw meat, S. Poona infection also occurs from contact with reptiles. Additionally, S. Poona tends to invade the blood stream more frequently than other NTS serotypes. It is important to increase public awareness that NTS infection may occur from being in contact with reptiles. Furthermore, it is crucial to obtain blood cultures when clinical symptoms are sustained, even for cases of gastroenteritis.
