Phenotypic and Genomic Characterization of ESBL- and AmpC-β-Lactamase-Producing Isolates from Imported Healthy Reptiles.

Background/objectives: Reptiles are known reservoirs for members of the . We investigated antimicrobial resistance (AMR) patterns, the diversity of extended-spectrum-/AmpC-β-lactamases (ESBL/AmpC) genes and the genomic organization of the ESBL/AmpC producers.

Methods: A total of 92 shipments with 184 feces, skin, and urinate samples of live healthy reptiles were obtained during border inspections at Europe's most important airport for animal trade and screened for AMR bacteria by culture, antimicrobial susceptibility testing, and whole genome sequencing (WGS) of selected isolates.

Presence of Methicillin-Resistant Staphylococci and Carbapenemase-Positive Isolates on Surfaces in German Dog Daycare Facilities and Correlation with Cleaning Practices.

Many bacteria, including methicillin-resistant staphylococci and opportunistic pathogens such as (.) species, in particular members of the - () complex, are known to survive in environmental settings. This increases the risk of bacterial spreading and transmission to animals and humans, especially in institutions with a high animal population density.

Repeated Occurrence of Mobile Colistin Resistance Gene-Carrying Plasmids in Pathogenic from German Pig Farms.

The global spread of plasmid-mediated mobile colistin resistance () genes threatens the vital role of colistin as a drug of last resort. We investigated whether the recurrent occurrence of specific pathotypes and plasmids in individual pig farms resulted from the continued presence or repeated reintroduction of distinct strains. isolates ( = 154) obtained from three pig farms with at least four consecutive years of detection positive for virulence-associated genes (VAGs) predicting an intestinal pathogenic pathotype via polymerase chain reaction were analyzed.

Heartworm and seal louse: Trends in prevalence, characterisation of impact and transmission pathways in a unique parasite assembly on seals in the North and Baltic Sea.

The ectoparasitic seal louse, infects harbour () and grey seals () in the North and Baltic Sea. The endoparasitic heartworm parasitizes the right heart and blood vessels of harbour seals. The complete lifecycle of the heartworm is not entirely understood although the seal louse is assumed to serve as vector for its transmission.

Genotypic Characterization of Uropathogenic from Companion Animals: Predominance of ST372 in Dogs and Human-Related ST73 in Cats.

Extraintestinal pathogenic (ExPEC) account for over 80% and 60% of bacterial urinary tract infections (UTIs) in humans and animals, respectively. As shared uropathogenic (UPEC) strains have been previously reported among humans and pets, our study aimed to characterize lineages among UTI isolates from dogs and cats and to assess their overlaps with human UPEC lineages. We analysed 315 non-duplicate isolates from the UT of dogs (198) and cats (117) collected in central Germany in 2019 and 2020 utilizing whole genome sequencing and in silico methods.
