BACKGROUND: Morganella morganii is a Gram-negative, opportunistic pathogen that can cause a variety of infections, including bloodstream infections, especially in those with compromised immune systems. It is often resistant to antibiotics, making it a difficult organism to treat. Limited studies have addressed M. morganii, but the organism is becoming increasingly recognized as a public health threat. More research is needed to understand the epidemiology and virulence factors of M. morganii in Saudi Arabia, as well as to develop effective treatment strategies.
METHODS: This retrospective study included all M. morganii bloodstream infections patients admitted to five tertiary care hospitals in Saudi Arabia between 2015 and 2022.
RESULTS: The study population included 75 patients (45 males and 30 females) between the age of 53-72 with a 54% ICU admission rate. The most comorbidities were hypertension followed by diabetes. The most common symptoms were fever, cough, shortness of breath, vomiting, and fatigue. The study also found that M. morganii was often resistant to multiple antibiotics, including ciprofloxacin, trimethoprim/sulfamethoxazole, gentamicin, amoxicillin, nitrofurantoin, and colistin. The most common treatment for M. morganii bacteremia was carbapenems, followed by aminoglycosides, ciprofloxacin, and colistin. Source control measures, such as surgery, line removal, drainage, and tissue removal, were also used in some cases. The study found that the in-hospital mortality rate for M. morganii bacteremia was 41%. The risk of mortality was increased in patients who were admitted to the ICU, who were older than 65 years, and who had Klebsiella pneumoniae co-infection.
CONCLUSION: M. morganii bacteremia is a serious infection that is often resistant to antibiotics. Elderly patients and patients with comorbidities are at increased risk of mortality. Source control measures and appropriate antibiotic therapy are important for improving outcomes.
