Proteus spp.-taxonomy, clinical significance, and antibiotic resistance of a highly versatile pathogen

Area of Science:

• Microbiology
• Infectious Diseases
• Bacteriology

Background:

• Proteus species are common bacteria found in humans, animals, and the environment.
• Certain Proteus species, notably Proteus mirabilis, are significant pathogens causing urinary tract and bloodstream infections.
• These bacteria possess virulence factors like swarming motility and urease production, contributing to persistent and severe infections.

Purpose of the Study:

• To provide an updated overview of the taxonomy of Proteus species.
• To review the known virulence factors associated with Proteus infections.
• To summarize the current state of antibiotic resistance in Proteus isolates and its global health implications.

Main Methods:

• Literature review and synthesis of recent research findings.
• Analysis of taxonomic classifications and phylogenetic relationships.
• Compilation of data on virulence mechanisms and antimicrobial susceptibility patterns.

Main Results:

• Recent discoveries have expanded the known diversity of Proteus species.
• Established virulence factors contribute to the pathogenicity of Proteus.
• Increasing antibiotic resistance among Proteus isolates poses a significant public health challenge.

Conclusions:

• Proteus species represent a growing concern due to their pathogenicity and evolving antibiotic resistance.
• Continued research into Proteus taxonomy, virulence, and resistance is crucial for effective clinical management.
• Understanding these factors is essential for addressing the global health threat posed by Proteus infections.
