And, among the antagonistic isolates 9 isolates were observed to inhibit the growth of Fusarium oxysporium, a causal agent of banana wilt, and the inhibition rates were from 80% to 100%. According to the fundamental biological characteristics, the 9 endophytic bacteria belong to the genera, Acinetobacter, Bacillus, Brevibacterium, Alcatigenes and Burkholderia. The tests showed that the hyphae of pathogen had different degrees of tumefaction and rupture.

Objective This study was to detect the human papillomavirus and herpes simplex virus genotypes in biopsy specimens of cervical carcinoma and genital verruca by PCR-endonuclease cleavage.

近年来随着分子生物学技术在肿瘤病原病因学研究中应用，发现单纯疱疹病毒-2型和人乳头瘤病毒是引起妇女生殖器疣和诱发宫颈癌的重要病原之一［1～4］。

In addition to air some of the Central Plains and some micro-organisms (non-pathogenic micro-organisms saprophytic, Bacillus, is Achromobacter, as well as a small number of Streptococcus actinomycetes, yeast and fungi, and so on), there may be from a human body More pathogenic micro-organisms such as Mycobacterium tuberculosis, diphtheria bacteria, Streptococcus, Staphylococcus aureus, meningococcal, influenza virus, measles virus, etc.

除大气中原有的一些微生物（非致病性的腐生微生物、芽胞杆菌属、无色杆菌属、细球菌属以及一些放线菌、酵母菌和真菌等）外，也可能存在来自人体的某些病原微生物（如结核杆菌、白喉杆菌、溶血性链球菌、金黄色葡萄球菌、脑膜炎球菌、感冒病毒、麻疹病毒等）成为空气传播疾病的病原。

Theoptimal conditions were as follows: amidulin 1.25%,CaCO_3 0.05%, yeast0.6%,NaC1 0.7%,KH2PO4 0.3%. The stability of antagonistic substance produced by Q6 was studied. Theactivity of the inhibitive substance was influenced when time and temperaturewaxing. In 100℃for 30 minutes,the inhibitive zone diminished distinctly, but thesubstance still had inhibitive effect on the pathgen. In pH 3.0～above 9.5 forovernight or treated by Proteinase K, the inhibitive zone is not changed.

对其拮抗物质进行了温度、酸碱度和酶三个方面的稳定性试验，当温度达到55℃以上时，随着温度和时间的变大，抑菌圈逐渐变小，但直到100℃，30min时，对病原菌的生长仍有抑制作用；pH3.0～9.5以上静置过夜后，拮抗物质对病原指示菌产生的抑菌圈几乎没有发生变化；经过蛋白酶K处理后，拮抗物质对病原指示菌产生的抑菌圈不变。

The comparison of sequences showed that the determined sequence was most similar to those in GenBank (AF016546)(similarity level, 97.9%), Phylogenetic analysis indicated that the resulting sequence was more similar to those of Mycoplasma spp.(homo!ogy level, about 70%), but was farther from Anaplasma spp.( homology level, about 50%).

系统发育分析表明，所测序列与支原体属病原代表种的序列接近，同源性约为70%，而与无浆体科病原代表种的序列相差较远，同源性约为50%。

However, the area is less studied than other areas of endophyteresearch world wide. Therefore, a series of experiments were carried out in laboratory,glasshouse and field to compare the responses of endophyte infected plants andendophyte free plants of perennial ryegrass varieties to 10 fungal pathogensisolated from turf type ryegrass in Lanzhou. The pathogens used in the experimentswere Alternaria alternata、Bipolaris sorokiniana、Fusarium avenaceum、Curvularialunata、Ascochyta leptospora、Fusarium acuminatum、Fusarium chlamydosporum、Fusarium oxysporum、Fusarium solani and Gliocladium roseum. In addition, someprotective enzymes activity and alkaloids contents of E+ and E- plants were measuredand LpsA gene of the common strain - Lp19 and mutant strain -AR1 of Neotyphodiumlolii were sequenced to identify their ...

本研究在初步明确兰州市坪用黑麦草内生真菌及其病原真菌多样性的基础上，在实验室、温室和田间开展了系列研究，比较了带内生真菌和不带内生真菌的黑麦草在离体和整株条件下对细交链孢、离蠕孢、燕麦镰孢、新月弯孢、小孢壳二孢、锐顶镰孢、厚垣镰孢、尖镰孢、腐皮镰孢和粉红粘帚霉等10种病原真菌的抗病性，测定了E+和E-植株数种保护酶活性及其生物碱含量的变化。

On co-culture plates this strain showed high suppression effect on 21 fungal pathogens involved in oomycetes, ascomycetes, basidiomycetes and deuteromycetes.

与病原真菌对峙培养的结果表明，该菌株能对供试的卵菌、子囊菌、担子菌和半知菌的21个植物病原真菌均有很好的抑制作用。

The five major pathogenic fungi of three fruits rot diseases are : Dothiorella gregaria,Colletotrichum gloeosporioides,Trichothecium roseum,Macrophoma kawatsukai and Coniothyrium olivaceum. Ameng which Coniothyrium olivaceum is a new jujube pathgenic fungus.

从苹果、板栗、枣的病果上，分离到5 种病原真菌，其中Coniothyrium olivaceum 为枣果新病原－测定了6 种寄主上的Dothiorella gregaria 形态、酯酶同功酶及菌丝融合力，认为是一复合种，可区分为3 个专化型。
