Salmonella is an organism typically associated with gastrointestinal disease after exposure to contaminated food. Reptiles are also known reservoirs of Salmonella. Infrequently, Salmonella can cause extraintestinal infections and, rarely, infections involving the neck. Here, we report a case of cervical lymphadenitis in a boy caused by Salmonella enterica subsp diarizonae (Serogroup IIIb), an isolate associated with pet snakes, after direct exposure to a snake at an educational event at his school. Although evaluation of this child’s immune system was normal, it may be important to consider specific primary immunodeficiencies in children with invasive Salmonella infections caused by rare serotypes.
This is the first report of Salmonella cervical lymphadenitis in an immunocompetent pediatric patient with a known direct reptile contact. Primary immunodeficiencies, which can predispose children to invasive Salmonella infections, are reviewed. The child’s exposure to the reptile was at a school-sponsored educational exhibit raising the public health question of whether requirements should exist to inform visitors to similar educational experiences about the potential risk for reptile-transmitted Salmonella disease.
