摘要
鸡肺炎克雷伯氏菌可在２０～４５℃及ｐＨ５．５～１０范围内生长，最适生长温度为３７℃、最适ｐＨ值为７．０～７．６。在无盐条件下生长良好，最大能耐受８％ＮａＣｌ。该菌利用葡萄糖等产酸产气，利用构橡酸盐和尿素，Ｍ．Ｒ阴性．Ｖ－Ｐ阳性．不产生Ｈ＿２Ｓ和吲哚，不运动。对庆大霉素等药物敏感。小白鼠对本菌易感，家兔有抵抗力。
The biological characteristics of klebsiella pneumonia from chickens were described inthis paper.The experimental results show that the bacilli can grow at 20～45℃ and pH5.5～10.thesuitable temperaturc is 37℃ and the suitable pH is 7.0～7.6 for theirgrowth.The bacilli grow well on no salt media,and can endure 8%cent NaCl.Colonieson general agar are coloured grey white with fluorescence. and colonies on MacConkey’sor SS agar are coloured pink.There is no hemolysis on blood agar.Incubated at 37℃, thehacilli are often slightly oval in outline.and usually occur singly but sometimes in pairs surrounded by capsules,varying in size from 0.5～0.9 um in width and 0.8～1,6um inlength.and do not produce spores. After repeated stibculturing, there is a tendency forcapstiles to be lost and the bacilli become smaller. Incubated at 25℃ 40℃, there is atendency for their size to be smaller and some are similar to coccus, varying in size from 0.5～0.7um in width and 0.5～1.4 um in length. Incubated at 45℃, the bacilli and theircapstilcs change into thick and bigger ones, varying in size from 0. 66～1. 42 um in widthand 0.95～2.84 um in length.The bacilli produce acid and gas in sevcral carbohydrates.including glucose.lactose and so on. and hydrolyse sodium citrate and urea. and are methyl red negative and Voges Proskauer positive. and do not produce H_2S and indol.and are non motile, The bacilli are sensitive to some drugs such as Gentamycini sulfate and so on,Mice are sensitive to the bacilli ,while rabbits are not.
