Antimicrobial drug susceptibility of Staphylococcus aureus from subclinical bovine mastitis in Italy / P. Moroni, G. Pisoni, M. Antonini, R. Villa, P. Boettcher, S. Carli. - In: JOURNAL OF DAIRY SCIENCE. - ISSN 0022-0302. - 89:8(2006), pp. 2973-2976. [10.3168/jds.S0022-0302(06)72569-3]
Abstract:
The antimicrobial susceptibility of 68 Staphylococcus aureus isolates collected during 2004 from milk of cows affected by subclinical mastitis was examined. The antimicrobial agents tested were the β-lactams, penicillin G, amoxicillin, ampicillin, cloxacillin, amoxicillin + clavulanate, cephalonium, and cefoperazone; and other drugs including lincomycin, oxytetracycline, doxycycline, and kanamycin. Minimum inhibitory concentrations recorded show that only certain β-lactamase-resistant penicillins (specifically cloxacillin) or penicillin combinations (amoxicillin + clavulanate) were consistently effective against Staph. aureus, whereas the other β-lactam derivatives and drugs from other pharmacological groups were either moderately effective or ineffective. Thus, β-lactamase-resistant penicillins are to be considered the antimicrobial agents of choice for treatment of bovine mastitis resulting from infection by Staph. aureus.
