Carbapenem-resistant Acinetobacter baumannii (CRAB) are emerging worldwide. In South America, clinical isolates presenting such a phenotype usually do not belong to the globally distributed international clone 2 (IC2). The majority of these also resistant multiple other antimicrobials and often designated extremely drug-resistant (XDR). aim this study was characterize resistance mechanisms presented by 18 carbapenem-resistant A. from five different Brazilian hospitals. Species identification...
Abstract Objectives To characterize a novel acquired MBL, BIM-1, in Pseudomonas #2 (subgroup P. guariconensis) strain isolated from the Aurá river located Brazilian Amazon hydrographic basin. Methods WGS using an Illumina® MiSeq System was used to genome of sp. IEC33019 strain. Southern blotting/hybridization assays were performed confirm location MBL-encoding gene, blaBIM-1 (Belém Imipenemase). Antimicrobial susceptibility testing, cloning, and biochemical phenotypic characterization...
ABSTRACT This retrospective study aimed to investigate the impact of emergence new variants and epidemiological scenario on hospitalization rates unvaccinated children (0–12 years) in Brazil. The included 1614 admitted a hospital between March 2020 December 2022 but 101 (6.3%) them testing positive for COVID‐19 via RT‐PCR. frequency cases increased from 7.5% 9.3% with Omicron variant. Children over 5 years old comorbidities accounted most (69% [70/101]). Sickle cell anemia was frequent...
Since its first report, the class A Brazilian Klebsiella carbapenemase (BKC) has been detected only among Enterobacterales isolates from hospitals. In this study, we characterized a multidrug-resistant Pseudomonas juntendi clinical isolate and identified 43.3-kb plasmid carrying blaBKC-1 1 integron (In1996) containing arr-2, qnrVC1, dfrA21, aac(6')-Ib' gene cassettes. Our results confirm ability of putida group to acquire antimicrobial resistance determinants further act as reservoirs.

Staphylococcus epidermidis (SEPI) é um agente comensal oportunista predominante na pele com habilidade de formar biofilme, porém comumente associado às Infecções Musculoesqueléticas (IME) ou sem implantes. Neste estudo, buscou-se identificar marcadores fenotípicos e genotípicos que diferenciem as formas patogênicas causadoras IME das comensais da pele. Um total 43 isolados SEPI, provenientes IMEs (n=28) swabs pessoas saudáveis (n=15) foram estudados. O perfil fenotípico foi avaliado por...
O vírus pandêmico SARS-CoV-2 evoluiu e variantes de preocupação (VOC) foram substituindo as anteriores até que uma nova VOC denominada Ômicron disseminou-se rapidamente suplantou a Delta circulava pelo país desde maio 2021. Em São Paulo, onda casos determinou grande impacto no primeiro trimestre 2022, gerando milhares infecções além internações óbitos. Descrever características dos pacientes hospitalizados durante da variante complexo do Hospital Paulo (HSP)–UNIFESP. Foram avaliados dados...
Na última década, a emergência de Pseudomonas do grupo putida (PPG) vêm recebendo um maior destaque por conta sua capacidade causar infecções nosocomiais e plasticidade genética, sendo capazes adquirir elementos genéticos móveis (EGM) contendo genes resistência aos antibióticos. Neste estudo investigamos o resistoma contexto genético espécies distintas isolados clínicos pertencentes PPG relevância no cenário brasileiro atual. Um total 12 resistentes carbapenêmicos foram recuperados uma...
