Abstract
Mastitis je najčešda i najskuplja bolest mliječnih krava. Procjenjuje se da od ukupnog broja muznih krava njih približno jedna tredina pati od infektivne upale vimena. U najvedem je broju slučajeva mastitis posljedica galaktogene penetracije patogenih bakterija u vime životinje. Najčešdi uzročnici mastitisa u mliječnih krava su: Staphylococcus aureus, Streptococcus agalactiae, Streptococcus dysgalactiae i Streptococcus uberis. Međutim, danas je uspjeh liječenja mastitisa antibioticima ograničen bududi da je vedina tih bakterijskih vrsta postala rezistentna na antibiotike. Stoga su bakteriocini bakterija mliječne kiseline koji imaju visoki antibakterijski potencijal prema brojnim patogenim bakterijama i pri tom ne stvaraju rezistentnost, postali predmetom intenzivnih istraživanja u prevenciji i liječenju mastitisa. Djelotvorni bakteriocini u prevenciji i liječenju mastitisa razni su oblici nizina, lakticina i aureocina. Bakteriocini djeluju brzo na osjetljive organizme staničnom lizom te na taj način sprječavaju da ne dođe do razvoja rezistencije kod patogena. Bakteriocini u liječenju mastitisa mogu djelovati samostalno ili u sinergiji s drugim bakteriocinima ili antibioticima.
Abstract (english)
Mastitis is the most common and most expensive disease in dairy farming. It is estimated that one third of dairy cows suffer from infectious udder inflammation. In most cases, mastitis is a consequence of penetration of galactogenic pathogenic bacteria into the udder of the animal. The most common causes of mastitis in dairy cows are: Staphylococcus aureus, Streptococcus agalactiae, Streptococcus dysgalactiae and Streptococcus uberis. However, it has been harder to treat mastitis due to the emergence of antibiotic resistance in pathogens. Therefore, lactic acid bacteriocins, which have high antibacterial potential against many pathogenic bacteria and do not create antibiotic resistance, have become the subject of intense research in the prevention and treatment of mastitis. The most effective bacteriocins in prevention and treatment of mastitis are various forms of nisin, lacticin and aureocin. Bacteriocins act rapidly on susceptible organisms by cell lysis and with this rapid action could ensure that resistance is less likely to develop by pathogens. Bacteriocins can act independently or in a synergy with other bacteriocins or antibiotics when used in the treatment of mastitis.
