[Identification and antibiotic susceptibility of Aeromonas spp. in a University Hospital in the city of Buenos Aires].

Aeromonas spp. are opportunistic pathogens that cause both intra- and extraintestinal infections. The objective of this work was the phenotypic and genotypic characterization of a collection of Aeromonas strains, in addition to determining their sensitivity to different antimicrobials.

Insights into AMA205's Unprecedented Antibiotic Resistance.

The rise of antibiotic-resistant bacteria in clinical settings has become a significant global concern. Among these bacteria, stands out due to its remarkable ability to acquire resistance genes and persist in hospital environments, leading to some of the most challenging infections. Horizontal gene transfer (HGT) plays a crucial role in the evolution of this pathogen.

Xanthomonas citri pv. eucalyptorum strain 4866-2_S43 (formerly X. axonopodis pv. eucalyptorum): the causal agent of bacterial leaf blight on eucalypts recovered in Argentina.

We report the draft genome assembly of strain 4866-2_S43 isolated from a eucalyptus lesion in Argentina and what until recently was caused by pv. (). The genome size is 5 188 607 bp, with a G+C content of 64.

Hetero-antagonism of avibactam and sulbactam with cefiderocol in carbapenem-resistant spp.

Cefiderocol, a siderophore-cephalosporine conjugate antibiotic, shows promise as a therapeutic option for carbapenem-resistant (CR) infections. While resistance has already been reported in , combination therapies with avibactam or sulbactam reduce MICs of cefiderocol, extending its efficacy. However, careful consideration is necessary when using these combinations.

Carbapenem-resistant Acinetobacter baumannii (CRAB): metabolic adaptation and transcriptional response to human urine (HU).

Carbapenem-resistant Acinetobacter baumannii (CRAB) is a major human pathogen and a research priority for developing new antimicrobial agents. CRAB is a causative agent of a variety of infections in different body sites. One of the manifestations is catheter-associated urinary tract infection, which exposes the bacteria to the host's urine, creating a particular environment.
