Out of 1,278 animals clinically examined across 180 farms, 80 tested positive via PCR, resulting in a morbidity rate of 6.26% and a herd prevalence of 37.22%. The morbidity rates in the 19 districts surveyed ranged from 1.45% to 17.95%. Risk factor analysis revealed that unvaccinated animals had the highest incidence rate at 17.94% (P<0.05), with an OR of 5.52 (95%CI: 3.62–8.44). Additio...

To evaluate the probiotic potential of these isolates, various biochemical, morphological, and physiological tests were performed, followed by 16S rRNA gene sequencing to genotype the isolates. The tolerance of the isolates to pH, temperature, and bile salt, as well as their antimicrobial and adhesion ability, was evaluated. The results showed that the identified novel probiotic
