Abstract:
Morganella morganii is rarely isolated from nosocomial infections. However, postoperative infections due to Morganella spp. were documented in literature and eye involvements of the infections usually result in severe sequels. We present a severe case infection, which was caused by M. morganii subsp. morganii, firstly appearing as conjunctivitis and complicated by bacteremia. The infectious agent isolated from both conjunctival and consecutive blood cultures. Identification and antimicrobial susceptibility tests were performed with the Vitek 2(®) automated system. The isolate was resistant to cephalosporins and carbapenems and it had ability to produce extended spectrum beta-lactamases. Patient was successfully treated with intravenous ciprofloxacin according to susceptibility test results. This is the first report of M. morganii infection detected as a local infection then complicated by bacteremia.
Insights
This case report details a rare nosocomial infection caused by Morganella morganii, initially presenting as conjunctivitis and progressing to bacteremia. The bacteria showed resistance to common antibiotics, highlighting the need for vigilant diagnosis and treatment strategies.
Area of Science:
- Microbiology
- Infectious Diseases
- Ophthalmology
Background:
- Morganella morganii is infrequently implicated in nosocomial infections.
- Postoperative infections by Morganella species can lead to severe ocular sequelae.
Observation:
- A severe case of Morganella morganii subsp. morganii infection initially manifested as conjunctivitis.
- The infection subsequently complicated into bacteremia, with the pathogen isolated from both conjunctival and blood cultures.
Findings:
- The Morganella morganii isolate exhibited resistance to cephalosporins and carbapenems.
- Extended-spectrum beta-lactamase (ESBL) production was identified in the isolate.
- The patient was successfully treated with intravenous ciprofloxacin based on antimicrobial susceptibility testing.
Implications:
- This is the first documented case of M. morganii presenting as a localized infection that progressed to bacteremia.
- Highlights the potential for severe outcomes and the importance of early detection and appropriate antibiotic selection for M. morganii infections.
