从６１５例老年感染患者的临床标本中分离出４属１２种１９４株非发酵菌，其中假单胞菌株占２／３，绿脓杆菌和不动杆菌为主要病菌。７３．２％的非发酵菌从老年人呼吸道分离，其诱发的感染例数占老年人呼吸道感染者的第２位；泌尿系也分离出非发酵菌，占老年人该系统细菌感染的第４位。药敏分析显示，非发酵菌分离株对丁胺卡那霉素、妥布霉素、复达欣基本敏感，可为首选用药，而对头孢类抗生素耐药株较多。
Four strains of 12 non-fermentative strains isolated from clinical samples of 615 elderly patients were infected, of which Pseudomonas strains accounted for 2/3, Pseudomonas aeruginosa and Acinetobacter were the main pathogens. 73.2% of non-fermented bacteria isolated from the respiratory tract of the elderly, the number of cases of induced infection accounted for the elderly respiratory tract infection in the first two; urinary system also isolated non-fermentative bacteria, accounting for the elderly bacterial infections in the system 4 Bit. Drug susceptibility analysis showed that the non-fermenting bacteria isolates of amikacin, tobramycin, Fu Daxin sensitive, may be the preferred drug, and more resistant to cephalosporin antibiotics.
