中文摘要 | 等孢球蟲(lsospora lacazei Labbe)的囊孢時期(oocyst)隨寄主糞便排出後,如果環境適宜,內部即分裂而產生兩個孢子(spore)這一過程叫做孢子形成(sporulation),這時為其感染時期,本研究以數種理化因子處理等孢球蟲(lsosoralacazei),隨寄主糞便排出之囊包(occyst),觀察此等因子是否能阻遏其孢子形成(sporulation),甚至殺死囊孢(oocyst),藉以設法減少此種球蟲的感染。 研究結果,等孢球蟲(lsospora lacazei)的孢囊,對10%和15%氯化鈉溶液(sodium chloride solution),1%和2%福摩林(formalin)以及氫游子(pH 1 或 13)均具抵抗力;但水、稀濃度氯化鈉溶液(0.85%)以及較濃的福摩林(% formalin)均可阻遏其孢子形成(sporulation);5℃以下的低溫,40℃以上的高溫以及乾燥均可殺死囊孢;氧氣缺少時,可阻遏孢子形成,但不能殺死囊孢,故當氧氣恢復時,內部又迅速形成孢子。 |
英文摘要 | The effects of sodium chloride solution, formalin, pH, moderately low and high temperatures, drying and lack of oxygen, on the viability and ability of Isospora lacazei oocyst to sporulate were investigated. It was found that the ooeysts from the bengalee (Uroloncha domestica) are considerably resistant to various concentrations of sodium chloride solution, but the very dilute solution of sodium chloride (0.85%) and water are poor media for oocyst sporulation. Oocyst sporulation occurs normally in both 1% and 2% formalin, but is prevented by 5% formalin. As shown by tests in extreme pH values of 1 and 13. it appears that hydrogen ion has no effect on the oocyst sporulation. Temperatures as low as 4° to 5°C and as high as 40°C are lethal to the oocysts. The oocysts are severely distorted by drying. Lack of oxygen inhibits the oocyst sporulation temporarily, upon airing, oocysts sporulate rapidly again. |
