Ceftriaxone Resistant Salmonella enterica Serovar Kentucky as a Cause of Bacteremia and Gastroenteritis: A Case Report

Abstract

Salmonella enterica serovar Kentucky is an emerging human pathogen in developed countries and also a concern for public health in developing countries. Although genus Salmonella is usually susceptible to many antimicrobial agents, a recent increase in resistance has become a cause for concern. A case of ceftriaxone resistant Salmonella enterica serovar Kentucky causing bacteremia and acute gastroenteritis is reported in this paper. The Salmonella Kentucky isolate in this case was resistant to most classes of antibiotics. This is the first case report of Salmonella enterica serovar Kentucky resistant to ceftriaxone. Multidrug resistant patterns of Salmonella Kentucky are observed globally. Awareness of various nontyphoid Salmonella causing human infections is of utmost importance, because delayed identification, serotyping, and susceptibility testing may delay the administration of antibiotics leading to worsening outcomes.

“…Among them, ser. Kentucky has been considered a public health threat [52], as it has been identified as causing human pathologies, such as urinary tract infections or gastroenteritis [53,54]. This serovar has been isolated from a wide range of animals, ranging from pet reptiles (snakes, turtles, or lizards) [55] to poultry, dairy, cattle, or food [56], being an important source of human infections, directly through pets [55] or indirectly through food consumption [56].…”
