Salmonella Hessarek Gastroenteritis with Bacteremia: A Case Report and Literature Review.

ABSTRACT

Salmonella enterica subspecies enterica serotype Hessarek (Salmonella Hessarek) is considered a serovar with high host specificity and is an uncommon cause of disease in humans; no cases of S. Hessarek bacteremia have been reported in humans to date. On 16 July 2019, a young male presented abdominal pain, vomit, diarrhea, and fever up to 41 °C, a few hours after a kebab meal containing goat meat; he went to the Emergency Room, where a Film Array® GI Panel (BioFire, Biomerieux Company, Marcy-L´Étoile, France) was performed on his feces and results were positive for Salmonella. The culture of the feces was negative, but the blood culture was positive for Salmonella spp., which was identified as Salmonella Hessarek by seroagglutination assays. The patient was treated with ceftriaxone 2 g intravenously qd for 8 days; he was discharged in good general conditions, and ciprofloxacin 500 mg per os bid for 7 more days was prescribed, after exclusion of endocarditis and of clinical signs of complicated bacteremia. This case of Salmonella Hessarek gastroenteritis with bacteremia is probably the first case of bloodstream human infection due to this agent ever described. Further studies are needed to ascertain the global burden of S. Hessarek disease in humans.
