Mastitis is an inflammation of the mammary gland that affects dairy cattle worldwide causing economic losses. Coagulase-negative staphylococci (CNS) are the predominant cause of this type of infection. We have recently showed that coagulase-positive staphylococci could be misidentified. So, the aim ...

The reckless use of antibiotics for the treatment of bovine mastitis can increase bacterial resistance and harm the effectiveness of current treatments. Thus, new alternatives for mastitis treatment must be searched. Actinomycetes are capable to produce crude extracts with secondary active...
