Acinetobacter baumannii causes life-threatening infections that are becoming difficult to treat due to increasing rates of multi-drug resistance (MDR) among clinical isolates. This has led the World Health Organization and the CDC to categorize MDR A. baumannii as a top priority for the research and development of new antibiotics.

- Acinetobacter baumannii is a highly resistant pathogen causing challenging infections, leveraging a “persist and resist” strategy to survive harsh environments.
- A specific operon involved in degrading phenylacetic acid (PAA) plays a crucial role in how this bacterium responds to antibiotics and can influence its virulence and resistance.
- Disruption of PAA degradation increases A. baumannii's susceptibility to antibiotics and reduces its ability to cause infections, suggesting that targeting this pathway could lead to new treatments.
DNA replication is fundamental for life, yet a detailed understanding of bacterial DNA replication is limited outside the organisms Escherichia coli and Bacillus subtilis. Many bacteria, including mycobacteria, encode no identified homologs of helicase loaders or regulators of the initiator protein DnaA, despite these factors being essential for DNA replication in E. coli and B.

The paradigm chaperonin, EcGroEL, and its cochaperonin, EcGroES, assist in the folding of proteins via an ATP-dependent mechanism. In addition to the presence of and homologs, paralogs are found in many bacteria, including pathogens, and have evolved poorly understood species-specific functions.

The primary Chlamydia species associated with human disease are C.
