(Submitter supplied) A major reservoir for spread of the emerging pathogen Acinetobacter baumannii is hopsital surfaces, where bacteria persist in a desiccated state. To identify gene products influencing desiccation survival, a transposon sequencing (Tn-seq) screen was performed. Using this approach, we identified genes both positively and negatively impacting the desiccation tolerance of A. baumannii.

(Submitter supplied) Acinetobacter baumannii causes high mortality in ventilator-associated pneumonia patients and antibiotic treatment is compromised in multi-drug resistant strains resistant to beta-lactams, carbapenems, cephalosporins, polymyxins and tetracyclines. Among COVID-19 patients receiving ventilator support, multi-drug resistant A. baumannii secondary infection is associated with a two-fold increase in mortality. more...

(Submitter supplied) Pathogenic bacteria encounter a variety of stressful host environments during infection. Their responses to meet these challenges protect them from deadly damages and aid in adaption to harmful environments. Bacterial products critical for this protection are therefore interesting as suitable targets for new antimicrobials. To shed light on the complex array of molecular pathways involved in bacterial stress responses we challenged 32 diverse human pathogenic bacteria to 11 infection related stress conditions and catalogued their transcriptomes. more...

(Submitter supplied) Tigecycline, a protein translation inhibitor, is a treatment of last resort for infections caused by the opportunistic multidrug resistant human pathogen Acinetobacter baumannii. However, strains resistant to tigecycline were reported not long after its clinical introduction. Translation inhibitor antibiotics perturb ribosome function and induce the reduction of (p)ppGpp, an alarmone involved in the stringent response that negatively modulates ribosome production. more...

(Submitter supplied) Analysis of the effect of human pleural fluid on the transcriptome of Acinetobacter baumanii A118 Acinetobacter baumannii (Ab) is one of the most treacherous pathogens among those causing hospital-acquired pneumonia (HAP). A. baumannii possesses an adaptable physiology, seen not only in its antibiotic resistance and virulence phenotypes, but also in its metabolic versatility. In this study, we observed that A. more...

(Submitter supplied) Calprotectin (CP) inhibits bacterial viability through extracellular chelation of transition metals. However, how CP influences general metabolism remains largely unexplored. We show here that CP restricts bioavailable Zn and Fe to the pathogen Acinetobacter baumannii, inducing an extensive multi-metal perturbation of cellular physiology. Detailed here are the RNA sequencing files of WT A. baumannii ATCC 17978 grown plus or minus recombinant human calprotectin. more...

(Submitter supplied) Acinetobacter baumannii is a Gram-negative opportunistic pathogen that causes multiple infections, including pneumonia, bacteremia, and wound infections. Due to multiple intrinsic and acquired drug-resistance mechanisms, A. baumannii isolates are commonly multi-drug resistant and infections are notoriously difficult to treat. Therefore, it is important to identify mechanisms used by A. baumannii to survive stresses encountered during infection as a means of identifying new drug targets. more...
