The spread of carbapenemase genes, such as , in poses a public health threat. The aim of the study was to characterize the genome and plasmids sequences of an NDM-1-positive strain (IBCRE14), which was isolated in 2019 from a catheterized patient hospitalized in Italy. : Whole genome sequencing (WGS) of IBCRE14 was performed on extracted genomic DNA using Sequel I platform. Genome assembly was performed using "Microbial Assembly". Genomic analysis was conducted by uploading the contigs to ResFinder and PlasmidFinder databases from the Center for Genomic Epidemiology. IBCRE14 had a genome size of 4,018,329 bp and harboured genes coding for resistance to aminoglycosides (), phenicol (), tetracycline (), and trimethoprim (). A large plasmid (pIB_NDM_1) harboured antibiotic resistance genes against sulphonamide (), trimethoprim (), tetracycline (), rifampicin (), aminoglycosides (), and beta-lactams (, ). Furthermore, a small plasmid (pIB_COL3M) harboured a gene coding for quinolone resistance. The ability to conjugate and the presence of a composite antibiotic resistance island suggests that pIB_NDM_1 could both acquire more resistance genes and easily disseminate. To our knowledge, this is the first report on an untypable plasmid harbouring in in Italy.

Yersinia enterocolitica, a bacterial enteropathogen that produces a variety of clinical manifestations in humans, includes six biotypes (B), called 1A, 1B, 2, 3, 4 and 5 and about 70 serotypes. The biotypes exhibit diverse pathogenic potential; while 1B and 2-5 may show ability to produce clinical symptoms due to the presence of chromosomal and plasmid (pYV) virulence genes, B1A is supposed a non-pathogenic biotype since it lacks pYV plasmid. Therefore, although B1A strains cause diarrhea in humans, their pathogenic potential has not yet been extensively studied.

Agrobacterium-mediated gene transformation method is a vital molecular biology technique employed to develop transgenic plants. Plants are genetically engineered to develop disease-free varieties, knock out unsettling traits for crop improvement, or incorporate an antigenic protein to make the plant a green factory for edible vaccines. The method's robustness was validated through successful transformations, demonstrating its effectiveness as a standard approach for researchers working in plant biotechnology.

serovar Mbandaka, a prevalent foodborne pathogen, poses a threat to public health but remains poorly understood. We have determined the phylogenomic tree, genetic diversity, virulence, and antimicrobial resistance (AMR) profiles on a large genomic scale to elucidate the evolutionary dynamics within the Mbandaka pan-genome. The polyphyletic nature of this serovar is characterized by two distinct phylogenetic groups and inter-serovar recombination boundaries, that potentially arising from recombination events at the H2-antigen loci.

Urban water environments, including canals, harbours and estuaries are susceptible to contamination with antimicrobials and drug-resistant bacteria through domestic and industrial wastewater discharges and storm water overflows. There is potential for wildlife using these waters to acquire and transmit drug-resistant bacteria and antimicrobial resistance genes (ARGs) of clinical importance. This study aimed to assess clinically important drug-resistant bacteria in urban waterfowl, particularly mute swans.
