As a result of the detection of the pinewood nematode Bursaphelenchus xylophilus in Portugal, and its subsequent spread to Spain, intense surveys were conducted to screen for the presence of Bursaphelenchus species in Romania. Herein, we report recent surveys of insects potentially vectoring Bursaphelenchus species collected using trap trees or pheromone‐baited traps placed in the forest. Trap felled spruce trees (Picea abies) and pheromone‐baited traps were installed in six different counties in Romania (Bra?ov, Sibiu, Suceava, Hunedoara, Timi? and Dâmbovi?a). Ten different species of insects distributed among Curculionidae and Cerambycidae were obtained. Nematodes were extracted from insects and observed to validate the presence of Bursaphelenchus specimens. One female identified as Monochamus sutor was the only specimen carrying nematodes in the genus Bursaphelenchus. Nematodes were identified as B. mucronatus based on morphological and molecular features. This is the first detection and report of natural spread of B. mucronatus in Romania. The absence of B. xylophilus was confirmed in the areas of Romania surveyed in this work. 相似文献

Inflammatory processes were provoked in 35 rats by subcutaneous implantation of sterile cotton-wool pads and treated five days by means of various antiphlogistic substances. The action of sodium salicylate (administered alone or in conjunction with gamma-globulin or with glucose) proved similar to that of prednisolone which was given as control substance. Human gamma-globulin exhibited neither anti-inflammatory nor pro-inflammatory effects. Experiments with twelve rabbits revealed that the pyretogenic potential of sodium nucleinate, one per cent (0.01 g/kg body weight) was stronger than that of animal charcoal or peptone. Yet, the two latter substances may be used, as well. The antipyretic effect of sodium salicylate was not as intensive but just as reliable as that of aminophenazone, when both preparations were applied to rabbits with induced fever. Concomitant administration of glucose is recommended to prevent development of undesired side-effects, such as giddiness or ataxia. 相似文献
