Sažetak

Mastitis je jedna od najvažnijih bolesti na farmama mlečnih krava i predstavlja jedan od najčešćih povoda primene antibiotika. Ciljevi ovog istraživanja bili su: istražiti učestalost i trendove kliničkog mastitisa krava na velikoj komercijalnoj farmi, opisati kliničke karakteristike i odrediti infektivne uzročnike u određenom broju uzoraka mleka, kao i njihovu antimikrobnu rezistenciju. U našem istraživanju smo koristili evidenciju farme o kliničkom mastitisu za period 2016. i 2017. Godina. U istraživanju su korišćeni rezultati redovnog testiranja broja somatskih ćelija u mleku iz 2017. godine. Uzorci mleka od svih krava kod kojih je ustanovljen klinički mastitis tokom novembra i decembra 2017. godine su mikrobiološki ispitani i određena je antimikrobna rezistencija dobijenih bakterijskih izolata. Ustanovili smo da je broj krava sa kliničkim mastitisom iznosio 205 (47,7%) u 2017. godini, a broj krava sa kliničkim mastitisom u 2016. godini bio je 165 (38,4%). Pojava kliničkog mastitisa bila je veća u 2017. godini po mesecima i ukupno u odnosu na 2016. godinu. U 2017. godini ponovljeni slučajevi kliničkog mastitisa su iznosili 45,4% (93/205). U 2016 godini ponovljeni slučajevi kliničkog matitisa su iznosili 29,7% (49/165). Prosečno trajanje kliničkog mastitisa u 2016. godini bilo je 3 dana, a u 2017. godini 4,5 dana (broj dana u kontinuitetu u evidenciji). Broj somatskih ćelija u mleku kod više od polovine testiranih životinja u februaru i julu 2017. godine bio je veći od 200.000 SC/ml (testirano 236 odnosno 169 krava). Od 23 uzorka mleka, 20 je imalo bakteriološki rast. U 9 uzoraka ustanovljena je S.aureus, u 6 streptococcus spp., u 4 koagulaza negativne stafilokoke i u jednom E.coli. Kod svih bakterijskih izolata najraširenija je rezistencija na lincomycin-spectinomycin (100%) gentamicin (92%), koje slede cefquinome (65%), linkomycin (53%) i erythromycin (47%). Izolati S.aureus su bili rezistentni na najveći broj ispitanih antibiotika.
