Effective treatment of Streptococcus uberis clinical mastitis to minimize the use of antibiotics.

摘要: Antibiotic regimens (intramammary antibiotic, penicillin-based parenteral treatment) and intramuscular oxytocin were tested for effectiveness against experimental infection by Streptococcus uberis with the following results from 54 animals: a) no treatment led to deterioration of infected quarters, requiring intervention within 48 h cow health; b) aggressive intramammary antibiotic at every milking achieved 70% clinical cure in 3 d 100% 6 d; overall bacteriological was 80%; c) alone used about 14 times as much 18% 91% d) combination treatments 61% 72%; e) labeled rates (1x 27% but treatment; 64%; f) use failed achieve improvement an increase severity mastitis; g) combining unsuccessful: 0% cures d, 10% significantly poorer than alone. Extended periods or antibiotics resulted positive inhibitory tests milk individual quarters up 8 after treatment. Aggressive most effective fastest clinically bacteriologically using least antibiotic.
