Infecção pelos vírus da leucemia felina e da peritonite infecciosa felina em felídeo selvagem de vida livre e de cativeiro da região do Pantanal matogrossense

Abstract: O virus da leucemia felina (FeLV) e o virus da peritonite infecciosa felina (FIPV) tem sido descritos em animais selvagens de todo o mundo e sao causadores de enfermidades imunodepressoras que podem ser prejudicais a sobrevivencia desses animais. O trabalho teve por objetivo relatar a identificacao de FeLV e FIPV em felideos selvagens de cativeiro e de vida livre da regiao do pantanal matogrossense. Um felideo selvagem de vida livre ( Felis pardalis ) e 16 felideos selvagens de cativeiro ( Felis yagouarundi , F. colocolo , F. weindii , F. concolor , Panthera onca ) foram avaliados quanto a presenca de FeLV e FIPV atraves das tecnicas de imunofluorescencia indireta e direta, respectivamente. Dos animais avaliados, 11 foram positivos para FeLV e 12 foram positivos para FIPV, sendo que 9 dos animais eram positivos para um ou ambos virus, 2 so para FeLV, 3 so para FIPV e 2 negativos. Os resultados sugerem que FeLV e FIPV podem estar disseminados pelos felideos selvagens e que a exposicao desses animais a importantes agentes patogenicos oriundos de animais domesticos, representa, associada a degradacao do habitat natural, um risco a preservacao da vida selvagem e a saude humana.

Mfg. teat integrated with sealing ring for baby bottles

Abstract: This procedure makes a teat from a soft plastic, which is connected to a ring of rigid plastic, for fastening to baby's bottle, the parts being injection moulded together. In the novel process, following injection of either ring or teat, a core is retracted, forming a cavity, either within the ring or outside the teat, in the region of the interconnection. The cavity is then filled appropriately, to form the corresponding part, completing the unit and the interconnection, by injection. Pref. the fastening ring is injected, then the core is retracted, forming a cavity inside it. The teat is then injected from within, connecting it to the fastening ring. The core moulding the ring disc interconnection section is retracted, the teat is filled in the cavity formed within the fastening section, by injection. Having injected the ring with an internal thread, the core is rotated back out of it. In an alternative, the teat is first injected then the core is retracted, forming a cavity outside the teat. The cavity is filled to form the ring, which is injected from outside, connecting it to the teat. The core forming the sealing section of the teat is retracted and the fastening ring is then injected-on. The work of injection may be shared by two tools, first injecting a part, transporting it, optionally on the core, to the second tool for completion, whilst a further fist part is being injected, in a continuous cycle.
