Dans les frottis sanguins colores au Giemsa d’un singe Cercocebus albigena capture en Republique Centrafricaine, trois especes d’hematozoaires ont ete identifiees : Plasmodium gonderi Rodhain et Van Den Berghe, 1936 (nouvel hote et nouvelle localisation geographique), Plasmodium petersi n. sp. et Plasmodium georgesi n. sp.. P. petersi se caracterise par la presence frequente chez les jeunes trophozoites de deux ou trois vacuoles coiffees d’un gros noyau ovalaire, par la morphologie des schizontes presque murs contenant de 12 a 18 noyaux arrondis, homogenes et assez gros, et possedant un cytoplasme bleu clair formant souvent une aureole tres pâle autour de certains noyaux, par la formation d’un pigment en aiguilles noires et par l’apparition tardive de granulations globulaires tres fines, grisâtres, de meme taille et relativement peu nombreuses, dans une hematie augmentee de volume, a bords nets et de teinte normale. P. georgesi n. sp. se caracterise par l’allongement en arc de cercle du noyau de ses trophozoites, par la grande taille et l’aspect polygonal des noyaux des jeunes schizontes immatures (contenant de 2 a 8 noyaux), par le nombre de noyaux des schizontes presque murs (22 a 26), par l’augmentation de volume importante des hematies parasitees qui prennent souvent une forme polygonale, par l’apparition relativement tardive de nombreuses granulations globulaires de tailles irregulieres, devenant de plus en plus violettes et intenses au fur et a mesure que le parasite murit, et par la formation tardive d’un pigment punctiforme jaunâtre.

It is necessary to distinguish the three main evolutionary lines which presently constitute the Trichostrongyloidea. We propose to raise the following taxa of Strongylida as presented in the CIH keys (1974). Ancylostomatina for Diaphanocephaloidea and Ancylostomatoidea. Strongylina for Strongyloidea. Trichostrongylina for Trichostrongyloidea. Metastrongylina for Metastrongyloidea. The Trichostronglyina suborder includes three superfamilies: Trichostrongyloidea, Molineoidea superfam. nov. and Heligmosomoidea superfam. nov.
有必要区分目前构成毛线虫纲的三条主要进化路线。我们建议在1974年的CIH数据库中增加以下Strongylida分类群。双头总科和钩虫总科的钩虫。圆线虫是圆线虫纲的缩写。毛圆菌属为毛圆菌纲。Metastrongylina为Metastrongyloidea。毛线虫亚目包括三个超科:毛线虫总科、毛线虫总科。11 .和Heligmosomoidea superam。11月。

Plasmodium berghei: the use of discontinuous urografin density gradients for the separation of exoerythrocytic malaria parasites. 柏氏疟原虫:使用不连续尿涂素密度梯度分离红细胞外疟原虫。

Urografin was used in the lower cushion of discontinuous density gradient systems, for the separation of human hepatoma cells (Hep G2) infected with exoerythrocytic P. berghei forms from uninfected cells. The hepatoma cells exhibited a rather heterogeneous density distribution, masking the possible density differences between infected and uninfected cells and hindering the efficient separation of both cell types. Purely osmotic damage caused by Urografin on human erythrocytes and hepatoma cells is very limited. On the other hand, the direct toxic effects on P. falciparum blood stages and on P. berghei exoerythrocytic stages are very pronounced. The growth of the former forms is partially inhibited after a pretreatment, but remains acceptable if the contact with Urografin is relatively short. It is almost completely blocked during permanent incubation. The latter forms are killed after 1 hour of contact with Urografin.

在不连续密度梯度系统的下垫层中使用尿路蛋白,用于从未感染的细胞中分离感染外红细胞伯氏假体的人肝癌细胞(Hep G2)。肝癌细胞表现出相当不均匀的密度分布,掩盖了感染细胞和未感染细胞之间可能的密度差异,阻碍了两种细胞类型的有效分离。尿素对人红细胞和肝癌细胞的纯渗透性损伤是非常有限的。另一方面,对恶性疟原虫血液阶段和伯氏疟原虫红细胞阶段的直接毒性作用是非常明显的。前一种形式的生长在预处理后被部分抑制,但如果与Urografin接触相对较短,仍然是可以接受的。在永久孵育期间,它几乎完全被阻断。后一种形式在接触Urografin 1小时后被杀死。

[In vitro study of leishmanicidal agents with drug carriers]. [药物载体利什曼尼杀灭剂体外研究]。

Antileishmanial chemotherapy is hampered by the location of parasites within lysosomal vacuoles of the macrophages which restricts the bioavailability of many potential antileishmanial compounds. In this study, the effectiveness of pentamidine targeted to the infected cells by a linkage to a colloidal drug carrier, methacrylate polymer nanoparticles was explored. In the same way, polyisoalkylcyanoacrylate nanospheres which have, in vitro, trypanolytic properties were also tested. The study was performed in an in vitro model using Leishmania major amastigote stages within the U 937 human monohistiocytic cell line. The antileishmanial activities of unloaded or pentamidine-loaded nanoparticles were compared to those of the free drugs. The 50% effective concentration of targeted pentamidine was 0.10 microgram/ml, while it was up to 2.7 micrograms/ml with the free drug after a 24-hour incubation time. The pentamidine-bound nanoparticles proved to be 25 times more active than the free drug. Unloaded polyisoalkylcyanoacrylate nanoparticles destroyed intracellular amastigote stages (50% EC = 15 micrograms/ml) but at a level close to the cytotoxic concentration.

抗利什曼化疗受到巨噬细胞溶酶体空泡内寄生虫位置的阻碍,这限制了许多潜在的抗利什曼化合物的生物利用度。在这项研究中,研究了喷他脒通过连接胶体药物载体甲基丙烯酸酯聚合物纳米颗粒靶向感染细胞的有效性。以同样的方式,还测试了具有体外锥虫降解性能的聚异烷基氰基丙烯酸酯纳米球。该研究是在体外模型中进行的,使用的是u937人单组织细胞系中的利什曼原虫主要无鞭毛体阶段。将空载或载喷他脒纳米颗粒与游离药物的抗利什曼原虫活性进行了比较。靶喷他脒的50%有效浓度为0.10微克/毫升,而游离药物在24小时的孵育时间后,其50%有效浓度高达2.7微克/毫升。与喷他脒结合的纳米颗粒被证明比游离药物的活性高25倍。未加载的聚异烷基氰基丙烯酸酯纳米颗粒破坏了细胞内的无尾石阶段(50% EC = 15微克/毫升),但其水平接近细胞毒性浓度。

Several small mammals were trapped in the Arrabida region (Portugal) and checked for the presence of trypanosomes which were found in 33 of the 197 (11.1 %) Mus spretus and in 9 of the 29 (31 %) Crocidura russula observed. To our knowledge, this was the first time that trypanosomes were isolated from these mammals species. In the liver of one dead C. russula was observed different parasite forms. The studies of infectivity to experimental rodents, analyses of the DNA buoyant density and the isoenzymatic profils, show that trypanosomes isolates from M. spretus were identical to Trypanosoma musculi isolates from Mus musculus. However the isolates from C. russula , although related to the isolates from murine rodents, were clearely separated from these and close to Trypanosoma microti . These findings may allow further studies on the detection of their vectors and on the study of trypanosome reproduction.
在葡萄牙阿拉比达地区捕获了几种小型哺乳动物,并检查了197只小野鼠中的33只(11.1%)和29只长尾鼠中的9只(31%)是否存在锥虫。据我们所知,这是首次从这些哺乳动物物种中分离出锥虫。在1例死亡的赤孢梭菌肝脏中观察到不同形式的寄生虫。对实验啮齿类动物的传染性研究、DNA浮力密度分析和同工酶谱分析表明,从spretus分离的锥虫与从小家鼠分离的肌肉锥虫完全相同。虽然与鼠类分离株有亲缘关系,但与小锥虫有明显的分离关系。这些发现可以进一步研究其媒介的检测和锥虫繁殖的研究。

Rearing conditions of sandflies (Phlebotomus argentipes) has been improved. Bloodfed females were initially maintained at 21-23° C for 5-7 days before allowing them to oviposit at 26-28° C and a proportion of flies were directly allowed to oviposit at 26-28° C just after feeding to see their oviposition survival and subsequently the refeeding rate. It was found that when the flies were maintained following the former method gave better results. It is proposed to keep the bloodfed sandflies at a temperature lower than its suitable feeding temperature for a period longer than its oogenesis period and then to bring back the flies at slightly higher temperature, required for oviposition to get better result in oviposition survival and subsequently multiple feeding activity.
白蛉(阿根廷白蛉)的饲养条件得到改善。将吸血雌蝇在21-23℃条件下维持5-7天,然后在26-28℃条件下产卵,部分蝇在摄食后直接在26-28℃条件下产卵,观察其产卵存活率和再摄食率。结果表明,采用前一种方法饲养蝇类效果较好。建议将吸血白蛉置于低于适宜取食温度的环境中,保持一段较其产卵期较长的时间,然后在稍高于产卵所需温度的环境中返回,以获得较好的产卵存活率和多次取食活动。
