自１９７８～１９９４年收治的脱硝产碱菌木糖氧化亚种感染１４例。发病前７８．５％（１１／１４）有原发病及诱因，院内感染７１．４％（１０／１４）。１４例中呼吸道感染５例，尿路感染３例，败血症、脑膜炎及腹膜炎各２例。本组病死率４２．８％（６／１４）。临床表现无特异性。诊断的确立有赖于实验室的细菌培养。该菌对氨基糖甙类、青霉素及氨苄青霉素等耐药，对氧哌嗪青霉素、复方新诺明等敏感。
From 1978 to 1994, the denitrification of Alcaligenes Xylose oxidized subspecies infection in 14 cases. 78.5% (11/14) had the primary disease and the predisposition before onset, and 71.4% (10/14) had nosocomial infection. Among the 14 cases, 5 were respiratory infections, 3 were urinary tract infections, and 2 were sepsis, meningitis and peritonitis. The case fatality rate of 42.8% (6/14). No specific clinical manifestations. The establishment of the diagnosis depends on laboratory bacterial culture. The bacteria on aminoglycosides, penicillin and ampicillin resistance, such as piperacillin, cotrimoxazole and other sensitive.
