Abstract

Nowadays, mastitis is one of the biggest problems in breeding dairy cattle. Treatment of this disease with conventional antibiotics is ineffective because many pathogens are resistant. Researchers have therefore been forced to look for new solutions, and metal nanoparticles (NPs) have been found to ...

Abstract

The aim of this paper is to describe a novel subpopulation of Staphylococcus haemolyticus isolated from intramammary gland infections (IMI) in cattle. In total, eight isolates originating from milk samples from two unrelated dairy farms were examined phenotypically (using the ID 32 STAPH system)...

Abstract

Staphylococci are the main etiological agents of bovine mastitis. Bacteriocins and nanoparticles have emerged as promising alternatives for the future development of antimicrobial agents. This study evaluated the activity of the bacteriocin nisin and bicelles of the synthetic cationic lipid...

Abstract

Subclinical mastitis, generally caused by Staphylococcus aureus, has a global economic impact all over the world. Hence, it needs to be resolved on higher priority which may be attained via. selection of mastitis resistant animals or inclusion of mastitis resistant trait into herd apart from...

Abstract

Superantigens (SAgs) represent a diverse family of bacterial toxins that induce Vβ-specific T cell proliferation associated with an array of important diseases in humans and animals, including mastitis of dairy cows. However, an understanding of the diversity and distribution of SAg genes among...

Abstract

The objectives of this study were to (1) correlate pre-partum teat skin colonization with non-aureus staphylococcal (NAS) intramammary infection (IMI) in early lactation, and (2) evaluate infection dynamics of subclinical NAS IMI in goats during lactation in a small ruminant lentivirus-infected...

Abstract

The present study investigated the effects of N-acetylcysteine (NAC) on β-lactam antibacterial activity against 20 methicillin-resistant Staphylococcus aureus (MRSA) isolates from bovine mastitis. Minimum inhibitory concentrations (MIC) were determined by the E-test method. The presence of 10 mM...

Abstract

Staphylococcus is the most commonly isolated genus from animals with intramammary infections, and mastitis is the most prevalent disease that affects dairy cows in many countries. These pathogens can live in biofilms, a self-produced matrix, which allow them evade the innate immune system and the...

Abstract

Bacteriocins have been suggested as an alternative to conventional antibiotics for the prevention and treatment of mastitis infections. Predominant bacteria associated with bovine mastitis (n=276 isolates) were evaluated for their susceptibility to bovicin HC5, a ruminal bacteriocin produced by ...
