More than twenty isolates of the bacteriophage of Xanthomonas ory-zae from leaves and seeds of diseased rice plants and irrigation waterof diseased paddy fields were separated into two groups on basis of th-eir morphology and other properties.Phages of group XOP 1(repres-ented by isolate OP-3)produce large plaque about 3 mm in diame-ter.It is tadpole shaped with a polyhedral head of 65 nm in diameter,and a striated non-contractile tail of 140×18 nm in size.The latent pe-riod and raising period are respectively 40 and 30 minutes,and th-eir average burst size is about 35 plaque forming units(PFU)per cell.Phages of group XOP 1 are completely inactivated by heat treatment at58℃ for 10 minutes,and the unadsorbed free phages of this group areinactivated by ferric salts solution(10~(-4)M).Phages of group XOP 2,represerted by isolate OP-12,produce small plaque about 1 mm in dia-meter.It is also tadpole shaped,with polyhedral head of 70 nm in di-ameter,and a short contractile tail 90×20nm in size.The latent periodand raising period are 80 and 50 minutes respectively,and their averageburst size is about 8 plaque forming units per cell.Phages of groupXOP 2 are conpletly inactivated by heat treatment at 68℃ for 10 minutes.Serologically they are also different,experemented phages of groupXOP 1 and XOP 2 are specific to Xanthomonas oryzae,but phages of gro-up 2 is much broader in spectrum of its host than group XOP 1 judgingfrom their reaction to different isolates of Xanthomonas oryzae. 从感染白叶枯病的稻叶、种子和田水中先后分离到24株噬菌体,测定了它们在琼胶平板上形成噬菌斑的大小、血清学反应、热钝化温度、铁盐的钝化作用、寄主范围、一级生长曲线以及在电镜下观察它们的形态。根据测定结果,可将它们区分为两个类群。第一群称为XOP 1型,以OP—3为代表,其噬菌斑直径为3～5毫米,热钝化温度为58℃/10分钟,易为三价铁盐所钝化;寄主范围较窄;潜育期为40分钟,上升期30分钟,平均裂解量为35个。第二群称为XOP 2型,以OP—12为代表,噬菌斑小,热钝化温度68℃/10分钟,对三价铁盐不敏感,潜育期80分钟,上升期50分钟,平均裂解量为8个。它们都是蝌蚪形,但OP—3的尾部细长而不能收缩,OP—12的尾部短粗而能收缩。 This papei reports the effects of aciaci-nomycin B(ACM B) on multiplication and DNA polymerase activities of HSV-2.

When mice were administered once intraperitoneally with different dosages of Poriatin, both cell number and morphology of peritoneal macrophages changed significantly 4 days later, lysosomal enzyme content and release and pinocytic and phagocytic rate being increased concomitantly with increment of biosynthesis of protein and RNA. Por-iatin-elicited macrophages also showed changes in ectoenzyme activities and inhibition of cytopathic effect (CPE) and plaque-forming unit (PFU) induced by herpes simplex virus type 1 (HSV-l) on Vero cells. The above results indicate that Poriatin could activate mouse peritoneal macrophages in vivo. 给小鼠腹腔1次注射不同剂量的茯苓素后,小鼠腹腔巨噬细胞百分数、形态以及细胞膜酶活性发生明显改变,吞饮、吞噬功能和溶酶体酶含量及释放显著提高,并伴随RNA和蛋白质合成加快。茯苓素体内诱导的小鼠腹腔巨噬细胞在体外抗病毒作用加强.   << 更多相关文摘      相关查询 plaque forming plaque forming unit plaque forming cells plaque forming cell plaque forming test atherosclerosis plaque forming plaque-forming plaque forming cell (pfc) plaque-forming cells plaque forming inhibition experiment plaque-forming cell plaque-forming units
