查询词典 pathogenicity

Avian influenza virus was isolated from the caecal tonsil, faeces, and kidney of the domestic ducks. The isolated virus was identified as a highly pathogenic H5N1, with a haemagglutinin proteolytic cleavage site deduced amino acid sequence of ... QREKRKKR/GLFGAIAG ...

Six different deletion and insertion mutants of BBSV-X were constructed and these were inoculated to Chenopodium amaranticolor. The preliminary results show that the sat-RNA could enhance symptom of BBSV-X and its insertion mutants on Chenopodium amaranticolor, but the pathogenicity of the CP deletion mutants was reduced.

构建了BBSV-X基因组6个缺失和插入突变体，将它们的体外转录物单独或与sat-RNA一起混合接种苋色藜，初步实验结果表明，sat-RNA能增强全长BBSV-X基因组及含全长基因组的突变体对苋色藜所致的症状，但减轻CP缺失突变体的致病性。

Clostridial enteritis of pigs with different ages was identified from4 farms by the bacteriology, determination of the toxin and its pathogenicity as w ell as clinical signs.

对4个规模化猪场不同日龄发病猪进行了病原学、力及毒素测定，并结合临床综合诊断确定为猪魏氏梭菌病。

In the mortality studies, 8 isolates infected more than 80% of the grubs, another 65 isolates infected more than 50% of the grubs and the rest of the isolates had a low level of pathogenicity with 107 conidia/mL concentration.

於致死试验中，有8个分离株感染了超过80%的蛴螬，另有65个分离株感染了超过50%的蛴螬，而其余浓度为10^7 conidia/mL的分离株致病力低。

The above results can summarize the function of STK1: insignificant effect on mycelium development and growth but related to the pigment accumulation in hypha; key factor regulating the conidial development; related to the HT-toxin activity and pathogenicity.

结论推测，STK1基因对玉米大斑病菌菌丝的生长发育没有影响，但可能与菌丝中色素等物质的积累有关，并调控病菌分生孢子的发育、HT-毒素的活性和致病性。

NY1 was also strongly pathogenic to the weeds C. virgata and Digitaria sanguinalis but had light or no pathogenicity to most crops.

菌株NY1对马唐和虎尾草也有很强致病性，但对于大多数供试栽培植物致病性很弱或无致病性。

The dimorphic transition of yeast and hyphal forms is one of most determinants in Candida albicans for its pathogenicity. This transition is regulated by several signal transduction pathways.

白念珠菌的形态转换是其致病性最重要的决定因素之一，这种形态变化受各种外界信号和细胞内信号转导途径的调控。

Barnyard grass, Echinochloa crus-galli, is one of the notorious weeds worldwide. To explore the potential of Alternaria augustiovoidea strain AAEC05-3 as mycoherbicide to control barnyard grass, the effect of inoculum potential and spray volume on the pathogenicity of strain AAEC05-3 to barnyard grass and host specificity of strain were studied using pot experiment.
