Acinetobacter spp. as nosocomial pathogens: Epidemiology and resistance features

Area of Science:

• Infectious Diseases
• Microbiology
• Epidemiology

Background:

• The genus *Acinetobacter* is a significant cause of hospital-acquired (nosocomial) infections globally.
• Multidrug-resistant *Acinetobacter baumannii* is a growing clinical concern due to its association with severe outbreaks and high mortality rates.
• While *A. baumannii* is frequently implicated, other *Acinetobacter* species also contribute to nosocomial infections.

Purpose of the Study:

• To review the role of *Acinetobacter* species as nosocomial pathogens.
• To analyze the persistence, antimicrobial resistance patterns, and epidemiology of *Acinetobacter* spp. in healthcare settings.

Main Methods:

• Literature review of studies on *Acinetobacter* spp. as nosocomial pathogens.
• Analysis of data on antimicrobial resistance and epidemiological trends.
• Synthesis of information on the clinical significance and persistence of these bacteria.

Main Results:

• *Acinetobacter* species are established nosocomial pathogens with increasing clinical significance.
• Multidrug resistance is a prominent feature, particularly in *A. baumannii*, complicating treatment and control.
• Epidemiological data highlight the widespread prevalence and outbreak potential of these bacteria in hospitals.

Conclusions:

• *Acinetobacter* species, especially multidrug-resistant strains, represent a critical challenge in hospital infection control.
• Understanding their epidemiology and resistance mechanisms is crucial for managing nosocomial infections.
• Continued surveillance and research are necessary to combat the spread of *Acinetobacter* pathogens.
