ABSTRACT
Objective To review the status of diagnosis and treatment for invasive fungal pulmonary infections(IFPI)in Lishui Central Hospital.Methods The clinical data of 79 patients with IFPI were retrospectively analyzed.Results The diagnostic status could be classified ills follows:6 eases had confirmed diagnosis,30 had clinical diagnosis,35 had suspected diagnosis and 8 misdiagnosed.The treatments were all effeetive in 6 COnfirmed cases;in 30 clinically diagnosed cases,6 were eriective.21 were inefiective and 3 died;in 35 suspected cases.3 were effective.25 were iHefieetive and 7 cflses did not receive antifungal treatment.Aspergillus and Cryptococcus pulmonary infections were predominant in confirmed cases.and the antifungal treatment lasted for 3 to 6 months.Conclusion Diagnosis and treatment for IFPI need to be improved.
ABSTRACT
OBJECTIVE To detect genes sul1 and sul2 in Stenotrophomonas maltophilia,and their relationship to drug resistance to trimethoprim-sulfamethoxazole(SXT).METHODS K-B was carried out to detect the drug resistance to SXT of S.maltophilia;minimal inhibitory concentration(MIC) was measured with micro broth dilution method.Genes sul1 and sul2 were amplified by PCR.RESULTS Eight isolates(7.8%) showed resistance to trimethoprim-sulfamethoxazole,sul1 Was positive in four isolates in which one contained sul2 also.Four isolates showed high MIC to SXT.CONCLUSIONS Genes sul1 and sul2 of S.maltophilia are associated with the high drug resistance to SXT.
