The emergence of antibiotic resistance among pathogenic microorganisms is a major issue for global public health, as it results in acute or chronic infections, debilitating diseases, and mortality. Of particular concern is the rapid and common spread of carbapenem resistance in healthcare settings. Carbapenems are a class of critical antibiotics reserved for treatment against multidrug-resistant microorganisms, and resistance to this antibiotic may result in limited treatment against infections. In addition to in clinical facilities, carbapenem resistance has also been identified in aquatic niches, including marine environments. Various carbapenem-resistant genes (CRGs) have been detected in different marine settings, with the majority of the genes incorporated in mobile genetic elements, i.e., transposons or plasmids, which may contribute to efficient genetic transfer. This review highlights the potential of the marine environment as a reservoir for carbapenem resistance and provides a general overview of CRG transmission among marine microbes.

To characterize the genomic features of a community-acquired Acinetobacter baumannii strain, co-carrying tet(X6) and bla genes, but was susceptible to tigecycline and carbapenems. The tet(X6) and bla genes were found on a 149,518 bp non-conjugative plasmid. The bla gene was silent, due to the presence of an intact ISAba3-like element upstream, which rendered the strain susceptible to carbapenems.

Carbapenem-resistant Acinetobacter baumannii (CRAb) is an urgent bacterial threat to public health, with only a few treatment options and a > 50% fatality rate. Although several resistance mechanisms are understood, it is still impossible to predict which mutations are most likely to occur. Here, we demonstrate that independent samples of Ab, exposed to different carbapenems with escalating concentrations, show concentration- and carbapenem-dependent trends in β-lactamase-isoform expression.

Gastrointestinal carriage of antimicrobial-resistant bacteria, especially carbapenemase-producing Enterobacterales (CPE), presents a critical public health threat globally. However, in many resource-constrained countries, epidemiological data on CPE is limited. Here, we assessed gastrointestinal carriage and associated factors of CPE among inpatient and outpatient children (≤ 5 years).

Klebsiella pneumoniae (KP) is a common opportunistic pathogen that emerged as a new critical threat to human health, due to its hypervirulence and widespread resistance against many antibiotics, including carbapenems. Alternative intervention strategies such as vaccines are not available. Cell-surface lipopolysaccharides (LPS) and capsular polysaccharides (CPS) are attractive targets for vaccine development.
