| [endocellular pathogenic bacteria in the monogenean euzetrema knoepffleri]. | intracellular bacteria (rickettsia) are found in the monogenean euzetrema knoepffleri, vesicular endoparasite of the amphibian euproctus montanus (urodela). in some conditions, they cause cytoplasmic damage in the host tissues, which demonstrates their pathogenicity. these bacteria are present during all the stages of the life-cycle of e. knoepffleri. their transmission from one generation to the next occurs through the gametes. | 1975 | 816501 |
| [the eyespots of the oncomiracidium of euzetrema knoepffleri (monogenea): ultrastructure and evolution during the life-cycle (author's transl)]. | euzetrema knoepffleri (monogenea, monopisthocotylea) is a parasite of the urinary bladder of euproctus montanus (amphibia, urodela). the eyespots of the oncomiracidium of e. knoepffleri are rhabdomeric; each anterior pigmented cell has one rhabdomere, each posterior pigmented cell has two rhabdomeres. this pattern is quite similar to that of the eyespot of another monopisthocotylea, entobdella soleae but the lack of cristalline lens in e. knoepffleri appears as a new feature of the monopisthocot ... | 1975 | 1146380 |
| a geographic mosaic of evolutionary lineages within the insular endemic newt euproctus montanus. | islands are hotspots of biodiversity, with a disproportionately high fraction of endemic lineages, often of ancient origin. nevertheless, intra-island phylogeographies are surprisingly scarce, leading to a scanty knowledge about the microevolutionary processes induced on island populations by plio-pleistocene climatic oscillations, and the manner in which these processes contributed to shape their current genetic diversity. we investigated the phylogeography, historical demography and species di ... | 2013 | 23163335 |
| the karyotypes of the corsican and sardinian mountain salamanders, euproctus montanus and e. platycephalus (urodela: salamandridae). | the chromosomes of euproctus montanus and e. platycephalus were studied by means of the c-banding method and the as-sat technique which are useful for identifying the single pairs of the complement and for recognizing nucleolar organizer regions. according to the morpho-structural characteristics shown by the specific karyotypes, it has been possible to draw some cytotaxonomic deductions concerning the karyological evolution within the insular group. | 1978 | 700007 |
