AI Article Synopsis
Article Abstract
Introduction: In this study, we report a clonal dissemination of carbapenem resistant Acinetobacter baumannii isolates due to the acquisition of blaOXA-23 in a regional hospital located in Brazilian Amazon Region.
Methods: The isolates were identified by MALDI-TOF and the carbapenemase-encoding genes were detected by multiplex-PCR. The genetic similarity was investigated by pulsed-field gel electrophoresis (PFGE).
Results: Only 10 (55.6%) isolates harbored the gene bla OXA-23. PFGE analysis revealed that these isolates belong to a single clone.
Conclusions: This dissemination strategy indicates the need for surveillance, adoption of control procedures defined in guidelines, and the careful administration of antimicrobials should be reinforced.

is a widely distributed nosocomial pathogen that causes various acute and chronic infections, particularly in immunocompromised patients. In this study, the activities of the K9-specific virulent phage AM24 and phage-encoded depolymerase DepAPK09 were assessed using in vivo mouse sepsis and burn skin infection models. In the mouse sepsis model, in the case of prevention or early treatment, a single K9-specific phage or recombinant depolymerase injection was able to protect 100% of the mice after parenteral infection with a lethal dose of of the K9-type, with complete eradication of the pathogen.

species are major pathogens responsible for hospital-acquired infections. This study aimed to compare the clinical characteristics, outcomes, and antimicrobial resistance between (AB) and non- (NBA) species. In this retrospective cohort study, we analyzed data from adult patients (aged 18 or older) with bacteremia treated at two tertiary hospitals from July 2020 to November 2023.

Microorganisms, including pathogens that cause skin, respiratory, and urinary tract infections, are widespread in our environment. Despite routine cleaning with bleach and disinfectants, the transmission of pathogens still occurs, leading to potential infectious diseases. This study aimed to determine the antibacterial effect of two coating formulas against common environmental pathogens like , , , , sp.

: Bacterial superinfections are common complications during viral infections, but the impact of multidrug-resistant (MDR) pathogens in critically ill patients affected by coronavirus disease 2019 (COVID-19) is still debated. : This is an observational, monocentric, and prospective study designed to investigate the incidence, risk factors, and outcomes of MDR bacterial superinfections in COVID-19 patients admitted to the intensive care unit (ICU). : A high incidence of superinfections (66%, 159/241) was observed: ventilator-associated pneumonia (VAP) (65%, 104/159) and bloodstream infection (BSI, 32%, 51/159) were the most common.

Antibiotic resistance is on the WHO's top 10 list of global public health threats due to its rapid emergence and spread but also because of the high morbidity and mortality associated with it. Amongst the main species driving this phenomenon is , a member of the ESKAPE group of medical assistance-associated infections causing species famous for its extensively drug-resistant phenotypes. Our findings note a 91.
