| OCA15. Annotation of the output with contextual information concerning the description of creative process and the content of the research/artistic/other activity, etc. | The text deals with the issue of mastitis in dairy farms with a special focus on the detection of virulence factors in staphylococci. The authors analyze the position of Staphylococcus aureus and other coagulase-negative staphylococci (NAS) as the main causative agents of intramammary infections, which cause significant economic losses and reduce milk quality. The work describes in detail the key molecular mechanisms of pathogenicity, especially the ability to form biofilm and adhesion properties, including toxin production. At the same time, it points to the growing problem of antimicrobial resistance, including the occurrence of methicillin-resistant strains (MRSA) with the mecA gene, which poses a serious risk to both animal and public health. |

| OCA16. Annotation of the output in English | Mastitis is still a major challenge that affects milk quality. The study is aimed to examine the health of the mammary gland and identify the udder pathogens and virulence factors that caused mastitis in 960 dairy cows and 940 ewes, respectively. We found that Staphylococci and streptococci are the most common causes of mastitis in those dairy animals. Coagulase-negative staphylococci (CoNS), along with the main udder pathogens such as S. aureus, S. uberis, and S. agalactiae, are a major concern for dairy animals. The majority of the virulence factors (production of hemolysis, gelatinase, biofilm, ability to hydrolyze DNA, and antibiotic resistance) were found in S. chromogens, S. warneri, and S. xylosus isolates from clinical and chronic cases of mastitis. S. aureus and CoNS strains tested by disk diffusion showed 77.0 and 44.2% resistance to one or more antimicrobial classes in mastitic milk samples from dairy cows and ewes, respectively. The presence of a methicillin-resistant gene mecA poses serious complications for treatment and indicates a health risk to milk consumers due to the resistance to β-lactam-antibiotics in two isolates of S. aureus and two species of CoNS isolated from cows’ mastitic milk samples. |
