 This case study highlights the importance of accurate diagnosis of uncommon pathogens and targeted antibiotic therapy. Using genetic sequencing, it was determined that the patient had Klebsiella aerogenes, a nosocomial pathogen that is increasingly associated with drug resistance and virulence profiles. Despite initial treatment with intravenous seftriaxone, the patient did not respond. Subsequent administration of meropenem resulted in successful recovery. This case serves as a reminder of the need to identify and treat uncommon pathogens, such as Klebsiella aerogenes, in order to reduce morbidity and mortality rates.
