Experts recommend implementing parenteral (intravenous) treatment on acute cases like summer mastitis [15, 46], because intramammary or local administration might not be the adequate route, due to intense pus discharge and inflammatory reaction: Considering that in vitro assays can show a wide spectrum of susceptibility to different antimicrobial families [28, 44], will be appropriate to evaluate antibiotics with high bioavailability on mammary gland or milk as P, sulfonamides and macrolides like E or tylosin [15]; nevertheless, there are several reports of T pyogenes strains resistant to the them [11, 44, 46] so, the use of these antibiotics should be considered according to results of respective antimicrobial susceptibility tests.
