Article Synopsis
- The bacterial pathogen, significant in both animals and humans, is linked to a variety of infections, highlighting the need to understand its genomic and metabolic features for effective control.
- Whole-genome sequencing and antimicrobial susceptibility testing were utilized to analyze 83 genomes from multiple animal hosts, revealing that the strains are not specific to hosts or body sites, indicating a broader infection potential.
- The study found conserved virulence genes and metabolic versatility in the pathogen, which may enhance its survival and competitiveness, raising concerns about its zoonotic potential and health impacts on humans and animals.
Liver abscesses, which occur in finishing cattle, are of significant economic concern to the feedlot industry. The causative agents include both subspecies ( and . ), (), and serotype Lubbock (S.

Methods: A virulence profiling-based approach was employed and six isolates were collected from various ecological zones of India.
This study aimed to determine whether the farm-level use of a Saccharomyces cerevisiae-based postbiotic was associated with Salmonella prevalence and concentration, serotype diversity, and antimicrobial resistance in the subiliac lymph nodes (LN) of cull dairy cows. In collaboration with two commercial processing plants in the Southwestern (SW) and Northeastern (NE) regions of the U.S.

- The study aimed to evaluate the impact of a direct-fed microbial (DFM) supplement on the presence and levels of E. coli O157:H7 in cattle feces across 20 feedlots in Nebraska, comparing those that used DFM to those that did not.
- A total of 1,320 fecal samples were collected over a 12-week period, revealing a mean within-pen prevalence of E. coli O157:H7 to be 13.5%, with higher prevalence rates noted in no-DFM pens during the peak sampling month.
- Key factors affecting fecal E. coli O157:H7 prevalence included the use of DFM, the month samples were taken, average pen body weight, and
