Detection of crenosoma spp., angiostrongylus vasorum and aelurostrongylus abstrusus in gastropods in Eastern Austria

Canine and feline cardiorespiratory parasites are of utmost relevance in veterinary medicine. Key epizootiological information on major pet metastrongyloids, i.e., Angiostrongylus vasorum and Crenosoma vulpis infecting dogs, and Aelurostrongylus abstrusus and Troglostrongylus brevior infecting cats, is missing from Austria. This study investigated their occurrence in 1320 gastropods collected in the Austrian provinces of Styria, Burgenland, Lower Austria, and in metropolitan Vienna. Metastrongyloid larvae were microscopically detected in 25 samples, and sequence analysis confirmed the presence of metastrongyloids in nine samples, i.e., A. vasorum in one slug (Arion vulgaris) (0.07%), C. vulpis in five slugs (one Limax maximus and four A. vulgaris) (0.4%), A. abstrusus in two A. vulgaris (0.17%), and the hedgehog lungworm Crenosoma striatum was detected in one A. vulgaris. The present study confirms the enzooticity of major cardiorespiratory nematodes in Austria and that canine and feline populations are at risk of infection

A pipeline for the creation of progressively rendered web 3D scenes

We present an end-to-end pipeline for the export of 3D scenes from content creaton tools to a real-tme rendering engine in an embeddable web-page, including a novel system for compression/decompression of textured polygonal meshes. We show that the compression/decompression outperforms the best state-of-the-art non-progressive alternatve, especially as bandwidth increases, showing that web-specifc techniques should consider the whole user pipeline. Our pipeline also includes progressivity, which is paramount for a good interactve user experience, and permits full user interacton with lower resoluton versions of the 3D scenes, while progressively higher resoluton data is downloaded. Finally, we discuss how our method may be used in the future to facilitate the transfer of animated meshes
