Abstract:
The Yersiniae are a group of Gram-negative coccobacilli inhabiting a wide range of habitats. The genus harbors three recognized human pathogens: Y. enterocolitica and Y. pseudotuberculosis, which both cause gastrointestinal disease, and Y. pestis, the causative agent of plague. These three organisms have served as models for a number of aspects of infection biology, including adhesion, immune evasion, evolution of pathogenic traits, and retracing the course of ancient pandemics. The virulence of the pathogenic Yersiniae is heavily dependent on a number of adhesin molecules. Some of these, such as the Yersinia adhesin A and invasin of the enteropathogenic species, and the pH 6 antigen of Y. pestis, have been extensively studied. However, genomic sequencing has uncovered a host of other adhesins present in these organisms, the functions of which are only starting to be investigated. Here, we review the current state of knowledge on the adhesin molecules present in the Yersiniae, and their functions and putative roles in the infection process.
Insights
Yersinia bacteria use adhesin molecules for virulence. This review explores known and newly discovered adhesins in Yersinia species, detailing their roles in infection and disease.
Area of Science:
- Microbiology
- Infectious Diseases
- Molecular Biology
Background:
- Yersiniae are Gram-negative coccobacilli with three main human pathogens: Y. enterocolitica, Y. pseudotuberculosis, and Y. pestis.
- These bacteria are crucial models for studying infection biology, including immune evasion and the evolution of virulence factors.
- Pathogenic Yersiniae rely heavily on adhesin molecules for their virulence.
Purpose of the Study:
- To review the current knowledge of adhesin molecules in Yersiniae.
- To discuss the functions of these adhesins in the infection process.
- To highlight newly identified adhesins and their potential roles.
Main Methods:
- Literature review of existing research on Yersinia adhesins.
- Analysis of genomic data to identify novel adhesin candidates.
- Synthesis of functional data regarding adhesin roles in pathogenesis.
Main Results:
- Established adhesins like Yersinia adhesin A, invasin, and pH 6 antigen are well-characterized.
- Genomic studies reveal numerous other adhesins in Yersiniae whose functions are under investigation.
- Adhesins play critical roles in bacterial adhesion and colonization during infection.
Conclusions:
- Adhesins are essential virulence factors for pathogenic Yersiniae.
- Further research is needed to elucidate the functions of newly discovered adhesins.
- Understanding Yersinia adhesins can provide insights into treating plague and gastrointestinal infections.
