Nosocomial Alcaligenes xylosoxidans Infection / 中华医院感染学杂志

ABSTRACT

OBJECTIVE To investigate the clinical distribution and resistance of Alcaligenes xylosoxidans,discussing risk factors of nosocomial infection and measures of prevention and treatment.METHODS We retrospectively analyzed 1323 isolated strains of Al.xylosoxidans in our hospital from Sep 2004 to Aug 2006.RESULTS For specimen from which Al.xylosoxidans was examined,sputum accounted for 99.85%,being the highest percentage.Al.xylosoxidans was especially distributed at respiratory ward(46.94%) and intensive care unit(ICU) ward(12.77%).Then was cardiovascular ward,endocrinology ward and hematology ward.The antibiotic drugs which had the high drug-resistance rate(i.e.more than 98%) were aminoglycoside(amikacin and gentamicin),quinolone(ciprofloxacin) and cefepime.But the drug-resistance rate to carbapenems,?-lactam/?-lactamase inhibitor combinations and the third generation cepholosporins(cefoperazone and ceftazidime) was less than 5%.CONCLUSIONS It is important for clinic to strengthen the disinfection for hospital environment and to use antibiotic drugs reasonably in order to control colonization and spread of Al.xylosoxidans in hospital.
