Ochrobactrum anthropi: An emerging pathogen causing meningitis with sepsis in a neurotrauma patient
1JPNA Trauma Centre, All India Institute of Medical Sciences, New Delhi, India. neha.rstg@gmail.com.
Abstract:
Ochrobactrum anthropi is an unusual emerging pathogen especially in the hospital environment. Most of the reported cases are nosocomially acquired infections in patients with various indwelling and invasive medical devices, such as central venous catheters and drainage tubes. We report a case of nosocomially transmitted invasive catheter related septicaemia with meningitis due to O. anthropi, in an elderly immunocompetent male with a head trauma admitted to a level -1 trauma centre. This report describes clinical and microbiological characteristics of rare pathogen and also highlights the importance of rapid identification, susceptibility testing of such opportunistic pathogens in trauma settings and its unique antibiotic susceptibility profiles. This requires prompt treatment with timely intervention, and appropriate antimicrobial therapy, alongside adherence to strict infection control practices.
Insights
Ochrobactrum anthropi, an emerging pathogen, caused severe catheter-related bloodstream infections and meningitis in an elderly trauma patient. Rapid identification and tailored antimicrobial therapy are crucial for managing these rare nosocomial infections.
Area of Science:
- Infectious Diseases
- Medical Microbiology
- Clinical Case Study
Background:
- Ochrobactrum anthropi is an emerging opportunistic pathogen frequently associated with nosocomial infections.
- Infections are often linked to indwelling and invasive medical devices, particularly in hospital settings.
Purpose of the Study:
- To report a rare case of nosocomially transmitted invasive catheter-related bloodstream infection and meningitis caused by O. anthropi.
- To highlight the clinical and microbiological characteristics of this pathogen in a trauma setting.
- To emphasize the importance of rapid diagnostics and susceptibility testing for effective treatment.
Main Methods:
- Case report of an elderly immunocompetent male with head trauma admitted to a level-1 trauma center.
- Clinical data collection and microbiological analysis of Ochrobactrum anthropi.
- Review of antibiotic susceptibility profiles and treatment interventions.
Main Results:
- The patient developed invasive catheter-related septicaemia with meningitis due to O. anthropi.
- The pathogen exhibited unique antibiotic susceptibility profiles requiring specific antimicrobial therapy.
- Successful management involved prompt identification, susceptibility testing, and targeted treatment.
Conclusions:
- Ochrobactrum anthropi poses a significant risk for severe nosocomial infections, especially in immunocompromised individuals or those with invasive devices.
- Rapid identification and susceptibility testing are critical for effective management of O. anthropi infections in trauma patients.
- Strict infection control practices are essential to prevent the transmission of such opportunistic pathogens in healthcare settings.

HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.
