It reported for the first time the change between niche breadth and niche overlap of the three kinds of parasite, which are Acanthocephala, Digenea and Capillaria in the digest tube of Monopterus albus , and the relation with the intensity of infection correlation.

摘 要：为探明寄生虫对黄鳝的危害，对黄鳝消化道内三大类寄生虫棘头虫门、复殖吸虫纲和毛细线虫属的生态位宽度和生态位重叠随季节的变化及其与寄生虫感染强度的关系进行了研究。

The benthic meiofauna was quantitatively investigated from 19 stations in the sea areas of the First-phase Project of Yangshan Deepwater Port in November, 2005 and ten meiofauna groups, including nematodan, copepodan, polychaetan, bivalvian, ostracodan, amphipodan, tanaidacean,cumacean, gastropodan and foraminiferan, were recorded.

2005年11月对洋山深水港一期工程海域19个站位的小型底栖动物进行了调查，共获得10个主要类群，包括线虫、桡足类、多毛类、双壳类、介形类、端足类、异足类、涟虫、腹足类和有孔虫。

Methods The target cDNA was amplified by PCR and PCR products were indigested by restriction enzyme Nco Ⅰ and Hind Ⅲ. Then the indigested products were recombined into pET-BBH and pET-BBH was expressed in E. coli BL21 (DE3) by IPTG inducing. Next, the expressed proteins were identified by SDS-PAGE, western blot and enzyme activity test. Finally, fluorescence quantitative PCR was used to test its expression quantity in different worm stages.

PCR扩增GAMMA-BBH cDNA基因，产物经NcoⅠ和HindⅢ限制性内切酶酶切后连接至原核表达载体重组为pET-BBH，在BL21(DE3)中用IPTG诱导表达，SDS-PAGE、Western blot和酶活性测定鉴定表达产物，用荧光定量PCR方法检测广州管圆线虫不同虫龄GAMMA-BBH的表达量。

Over a one-year period,1 600 snails and 415 crabs were collected and examined for larval trematodes, 11.8﹪ of snails were infected with one of 8 species dominated by M.eroliae(9.9﹪), and 80﹪ of crabs harbored M.eroliae metacercariae.

调查期超过一年，在检查的1 600只螺和415只蟹中，11.8﹪的螺感染了8种马蹄属线虫中的一种，且以滨鹬马蹄吸虫的感染占优势(9.9﹪螺感染)；80﹪的蟹感染滨鹬马蹄吸虫囊蚴。

The results showed that the free-living marine nematodes were the dominant group the percentage of which in the total number of meiofauna ranging betwean 76.1%~96.3%. The abundance of meiofauna in old mangrove district was the least and in bare beach where waste water flows was the most. There were a total of 37 putative species in the samples. The total number of recorded species was the lowest in the new mangrove district, and highest in the old mangrove district. The species diversity indexes, species evenness indexes and richness indexes in old mangrove district were all higher than those in new mangrove district. The dominant species and feeding types were different in three types of habitats.

结果表明：海洋线虫是凤林红树林中小型底栖动物中的绝对优势类群，占到小型底栖动物的76.1%~96.3%；从丰度来看，旧区白骨壤林中小型底栖动物的数量较少，有污水流过的光滩数量较大；4个断面共鉴定出海洋线虫37种，其中新区秋茄林中的生物多样性指数较低，旧区白骨壤林中群落具有较高的物种多样性；从出现的物种来看，新区秋茄林、旧区白骨壤林和光滩上出现的优势种和摄食功能群的类型各不相同。

By suspending cell culture from the callus of P. thugbergii and by fluorescent observation, a new method, which is easy and sensitive to observe cell activity and to test the phytotoxicity of various bacteria, was used. This method can be utilized to study the bacterial toxins. Cultured filtrates of some strains of the nematode-carrying bacteria were bioassayed for their toxicity to suspending cultured cells from P. thugbergii callus. Strong toxic effects were observed by the filtrates of Pseudomonas spp., P. fluorescence, and Sphingomonas spp., these bacteria species are coincide with those in the early stage of pine wilt disease.

本试验使用了黑松愈伤组织的细胞悬浮培养方法，用荧光方法观察各种细菌对植物细胞的毒性测定，这种方法具对细胞的活性观察容易、灵敏度高等特点，证明可用于细菌的毒素研究；对松材线虫携带的细菌的部分菌株，用其培养滤液对黑松愈伤组织的悬浮培养细胞的生物测定初步证明，松材线虫携带的细菌中以假单胞菌、荧光假单胞菌和少动鞘氨醇单胞菌的滤液对黑松细胞具有较强的毒性，这与松树发病早期出现的细菌种类相一致。
