Title: Ward Distribution and Drug Resistance Analysis of Acinetobacter baumannii
Abstract: OBJECTIVE To investigate the ward distribution and resistance of Acinetobacter baumannii.METHODS Bacteria culture and identification were adopted by conventional method.Susceptibility was tested by Kirby-Bauer method.RESULTS A.baumannii was the most isolated from sputum in all specimens,which accounted for 60.7%,being the highest percentage.Next was from secretion,accounted for 15.7%.A.baumannii was mainly distributed at wards,especially at neurosurgery ward.Next were at respiratary department,ICU and orthopedics wards.The resistance of A.baumannii were serious.Muti-drug resistance was common.The lowest drug resistance rate was to imipenem(13.5%).For 13 antibacterial agents,the rates of drug resistances were higher than 50.0%.For gentamicin,amikacin,ciprofloxacin,chloramphenicol,sulfamethoxazole,and piperacillin,the rates of drug resistance were 56.2%,60.7%,53.9%,62.9%,62.9% and 57.3%,respectively.For second and third generation cephlosporins,and aztreonam,the drug resistance rates were 51.7% to 66.3%.For cefoxitin and ampicillin,the drug resistance rates were higher to 89.9% and 91.0%.CONCLUSIONS The resistance of A.baumannii causing nosocomial is serious.The reasonable use of antibacterial agents must based on the result of susceptiblity test.The disinfection should be strengthened for hospital environment and medical staff in order to control existance and spread of A.baumannii in hospital.
