Distribution and drug sensitivity of pathogens in 133 children with suppurative otitis media / 国际检验医学杂志

ABSTRACT

Objective To guide proper clinical medication through analysing the main pathogen and the drug resistant situation of suppurative otitis media of the local children .Methods Making the bacterial culture and antibiotic susceptibility tests with the ear secretion collected randomly of 133 children with suppurative otitis media .Results Among the 133 cases ,110 pathogenic germs were separated totally ,as the detectable rate was 98 .23% ,and Among them ,56 streptococcus pneumoniae ,26 staphylococcus au‐reus (3 multi‐drug resistant to oxacillin) ,11 streptococcus pyogenes ,4 Haemophilus influenza and 13 others .Streptococcus pneu‐moniae was susceptible of ceftriaxoneo ,cefotaxime ,chloramphenicol ,levofloxacin ,quinupristin/dalfopristin and vancomycin ,while was resistant to clindamycin ,tetracycline ,sulfamethoxazole and erythromycin .11 .54% of the total detectable rate of MRSA in Staphylococcus aureus ,produce to β‐ lactamase detection rate was 84 .61% .Streptococcus pyogenes had a high resistance rate to erythrocin ,while a low rate to the other antimicrobial .Conclusion The main pathogen of the local children suppurative otitis media are Streptococcus pneumonia ,Staphylococcus aureus and Streptococcus pyogenes .The clinicians should use antibiotics reasonably according to the antimicrobial susceptibility results .
