A longitudinal study was designed in five dairy cattle farms to assess the within-farm dynamics of ESBL-/AmpC-/carbapenemase-producing and their resistance profiles, along with the genes conferring the resistance phenotypes. Twelve samplings were performed over a period of 16 months, collecting rectal feces from apparently healthy animals in three age groups (calves, heifers, and lactating cows) that were subjected to selective isolation in cefotaxime-containing media. Minimum inhibitory concentrations were determined by broth microdilution for 197 cefotaxime-resistant (1-3 isolates per age group and sampling date), and 41 of them were selected for long-read whole-genome sequencing.

We report here the draft genome sequence of an extended-spectrum β-lactamase (ESBL)-producing species isolated from rectal feces collected from beef cattle in northern Spain. Analysis of the draft genome identified the strain as a member of the newly described species .

ESBL-/AmpC-producing was isolated in 32.9% of dairy cattle herds, 9.

- Paratuberculosis, caused by Mycobacterium avium subsp. paratuberculosis (MAP), is a chronic infection affecting ruminants and is linked to diseases like Crohn's in humans.
- This study evaluated the performance of three methods—culturing, quantitative PCR (qPCR), and a peptide-mediated magnetic separation (PMS) phage-based assay—for detecting MAP in various milk types, like raw and powdered.
- Results showed that qPCR (94% sensitivity) and culture (83% sensitivity) were more effective than the PMS-phage method (40% sensitivity), indicating that qPCR and culture are the best options for MAP detection in dairy products.
Mycobacteria include obligate and opportunistic pathogens that cause significant human and animal disease. The burden of tuberculosis has been largely reduced in developed territories but remains a huge problem worldwide. The significance of nontuberculous mycobacteria is growing considerably, especially in developed regions with higher life expectancy and more therapy-related immunosuppressed individuals.
