Abstract:
Objective To investigate the distribution and antibiotic resistance characteristics of pathogen in mastitis patients and to provide important foundation for clinical rational antibiotic use .Methods The bacterial isolates from 114 mastitis specimens were collected .Identification and antimicrobial susceptibility testing were carried out .Results A total of 67 strains were isolated from clinical specimen ,in which Staphylococcus aureus[50 .7% (34/67)] and Staphylococcus epidermidis[44 .8% (30/67)] were themostcommonisolate,also Escherichiacoli[1.49% (1/67)],Klebsiellapneumoniae[1.49% (1/67)]andAcinetobactercalcoace-ticus[1 .49% (1/67)] were isolated .The rates of methicillin-resistant Staphylococcus aureus(MRSA) and methicillin-resistance to coagulase-negative Staphylococci(MRCNS) were 8 .8% and 46 .7% ,respectively .The sensitive rates of minocycline ,vancomycin , teicoplanin ,furadantin to MRSA strains were 100 .0% .The sensitive rates of vancomycin ,teicoplanin ,levofloxacin ,furadantin and oxacillin to methicillin-sensitive Staphylococcus aureus(MSSA) were 100 .0% .The sensitive rates of minocycline ,rifampin ,furadan-tin ,vancomycin ,teicoplanin and oxacillin to methicillin-sensitive to coagulase-negative Staphylococci(MSCNS) were 100 .0% .The sensitive rates of vancomycin ,teicoplanin ,minocycline and furadantin to MRCNS were 100 .0% .The resistance rates of penicillin to MRSA ,MSSA ,MSCNS ,MRCNS were 100 .0% .Conclusion Staphylococcus is the main pathogen of mastitis patients .Penicillin is not a first selective drug for acute mastitis .
