ABSTRACT
OBJECTIVE To investigate the evolution of drug-resistance of Staphylococcus aureus in children in Hubei tertiary level hospitals during four years and provide the evidence for clinically reasonable use of antibiotics.METHODS The summary data of drug sensitivity in clinical isolates of meticillin-resistant S.aureus(MRSA) and meticillin-sensitive S.aureus(MSSA) in children in Hubei tertiary level hospitals from 2004 to 2007 were investigated retrospectively and the results were analyzed statistically.RESULTS The tendency of infections with MRSA upgraded yearly during four years(5.7%→10.7%→40.8%→46.9%);the resistance rates of MRSA to various antibiotics were all higher than that of MSSA.The vancomycin-resistant S.aureus had not been detected.CONCLUSIONS The drug-resistance status of SA in Hubei is still very serious.We should adopt effective measurement to control the occurring and epidemic outbreak in combination with children physiological characteristic.
ABSTRACT
OBJECTIVE To investigate dynamically antibiotic resistance changing of Escherichia coli in Hubei province and provide the reference for clinical rational application of antibiotics.METHODS The WHONET4-5 software was used to analyze the antibiotic resistant rates of 2901 strains of E.coli isolated from all kinds of clinical specimen of children from 2003 to 2006 in the third grade hospitals of Hubei province.RESULTS Drug-resistance rate of E.coli in children group was lower than that in adult group.Except for 100.0% susceptibility to carbopenems such as imipenem and Meropenem,in the four years,drug-resistance of the other antibiotics showed ascending tendency.Ampicillin showed the highest drug-resistance rate(84%-90%).The lower(3%-25%) were amikacin,cefoxitin,ceftazidime,cefepime.CONCLUSIONS Antibiotic resistance of E.coli in children in Hubei province showed the ascending tendency.We should take effective measurement to control the spread and prevalence of the drug-resistant bacteria.
