The objective of this study was to analyze the changes in the microbiota of milk products during fermentation and storage. Two kinds of Yoghurt, one Kefir, and one Acidophilus milk were observed during the fermentation process and storage using 16S rDNA amplicon sequencing. Cow's, goat's, raw and pasteurized milk were also examined.

Of particular interest are antibiotics that have large consumption rates in both veterinary and human medicine, such as the tetracyclines and macrolide-lincosamide-streptogramin (MLS) group of antibiotics. A high load of these agents increases the risk of transmission of resistant bacteria and/or resistance determinants to humans, leading to a subsequent therapeutic failure.

- The global increase in fruit and vegetable consumption has sparked research into the presence of nontuberculous mycobacteria (NTM) in these foods, as NTM can impact human health.
- Researchers analyzed 178 samples of ready-to-eat, raw, and frozen fruits and vegetables, discovering that almost all contained Mycobacterium species, with some rare isolates present, including *Mycobacterium shigaense* in lettuce, marking its first detection outside of human patients.
- Although most NTM are nonpathogenic, their presence in fruits and vegetables may pose a health risk, especially for vulnerable populations like the immunocompromised, children, and the elderly.
The aim of this study was to determine possible differences in the faecal microbiota of dairy cows infected with Mycobacterium avium subsp. paratuberculosis (Johne's disease) in comparison with noninfected cows from the same herds. Faecal samples from cows in 4 herds were tested for M.

Samples from five rivers around the city of Brno were obtained during four seasons and analysed using 454 pyrosequencing of the 16S rRNA gene. The core composition of bacterial communities consisted of Actinobacteria, Bacteroidetes, Proteobacteria, Firmicutes, Fusobacteria, TM7 and others.
