【摘要】 <正> 绿脓假单胞菌(Pseudomonas aeruginosa)又称绿脓杆菌(Bact.pyocyaneum),最早由Gessard(1882)分离。Kaupp和Dearstyne(1926)首先从禽类分离到此菌。随后Biddle和cover(1959)又从CRD和“气囊病”的鸡的上呼吸道内,亦分离出该病原体。Stafseth等(1940)曾报道了各种年龄的禽类,都有绿脓假单胞感染的发生。鸡、火鸡和雉为常见的宿主。该菌可成为哺乳类、禽类及爬虫类的致病病因。1983年11月,我们从武汉市郊“华实”养鸡场调查、诊断中发现,该场来航星杂288蛋鸡群发生绿脓假单胞菌感染,并分离出病原体。鉴于蛋鸡发病及其所产生的病理演变更多还原

【Abstract】 One ot the first reports of psuedomonas aeruginosa infetion of laying hens in Hubei province was made by xu xiu—dong et al in 1983.ps. aeruginosa have been isolated from respiratory tracts (laryngotracheal mucus), liver, spleen, kidney and blood of laying hens(starcross—288).Iosses in infected flocks range 21.7%.ps. aeruginosa is a motile gram—negative, rod—shaped bacterium. It occurs singly or in short chains, strains produce round or ovoid, moist, smooth, fimbriate colonies.Fluorescent pigments are produced by strains, catalase, positive and aerobic, can ferment glucose with the production of acid. and control B. athracis growth in broth.Inoculated guinea—pigs, rabbits and mice die of septicemia.Affected chickens are depressed andmay have very high fevers—over 43℃. Diarrhea is common.Hemorrhages are frequently seen on the surface of the visceral organs. Enteritis hemorrhagic and extensive airsacculitis occur, ovaries and oviducts are commonly affected.更多还原
