Comparative genomic analysis of four multidrug resistant strains of Acinetobacter baumannii from the country of Georgia

ConclusionCirculating MDR A. baumannii exhibit genetic heterogeneity with variations in the structure and content of genomic A. baumannii resistance islands and encode multiple putative ARGs. This report represents the first clonal subtype information and genomic characterization of MDR A. baumannii in the country of Georgia and may inform future epidemiological investigations.

ConclusionAntimicrobial activity of minocycline was dramatically reduced in the presence of serum, which corroborated with our atypical serum protein binding findings. If validated, these results implied dose escalation might not the best approach to improve the clinical efficacy of minocycline for bacteremia. Future investigations will focus on the specificity and mechanism(s) of minocycline protein binding.

ConclusionsImportantly, A. baumannii with colistin heteroresistance phenotype was common. This could be a great concern, since that colistin is often used as a last-resort drug for treatment of A. baumannii infections, highlighting the care is necessary with colistin monotherapy. In addition, more effective strategy and surveillance are required to confine and prevent the inter- and/or intra-hospital dissemination of A. baumannii between our therapeutic centers.

AbstractPurpose of ReviewAcinetobacter baumannii (AB) is an infamous nosocomial pathogen with a seemingly limitless capacity for antimicrobial resistance, leading to few treatment options and poor clinical outcomes. The debatably low pathogenicity and virulence of AB are juxtaposed by its exceptionally high rate of infection-related mortality, likely due to delays in time to effective antimicrobial therapy secondary to its predilection for resistance to first-line agents. Recent studies of AB and its infections have led to a burgeoning understanding of this critical microbial threat and provided clinicians with new ammunit...

Conclusion: Gram-negative organisms, predominantly Acinetobacter, Citrobacter, and Pseudomonas spp, were prevalent on the hands of HCWs who access the cardiac ICU irrespective of the staff category. Antimicrobial resistance was high, with multidrug resistance and carbapenem resistance common among Citrobacter spp and Acinetobacter spp, respectively. Resistance to cefepime and ciprofloxacin was low. PMID: 31687206 [PubMed]

ConclusionsResults of the present study show that antimicrobial resistance in CNSAB isolates from burn wound infections in monitored hospitals in Iran is multifactorial, and also findings of the study suggested that local antibiotic prescription policies should be regularly reviewed, and efficient infection control measures should be observed. Therefore, further strengthening of surveillance of antimicrobial resistance is urgently needed in these regions.

Semin Respir Crit Care Med 2019; 40: 454-464 DOI: 10.1055/s-0039-1693160Antibiotic resistance is recognized as a key determinant of outcome in patients with serious infections influencing empiric antibiotic practices especially for critically ill patients. Within the intensive care unit (ICU), nosocomial infections and increasingly community-onset infections are caused by multidrug-resistant bacteria. Escalating rates of antibiotic resistance adds substantially to the morbidity, mortality, and cost related to infections treated in the ICU. Both gram-positive organisms, such as methicillin-resistant Staphylococcus aureus an...
