  3. Merogony / Objectivos do ADDAV Os principais objectivos de este projecto de investigação foram: Desenvolvimento de métodos de diagnóstico e vacinas, para espécies altamente patogénicas de Theileria sp. que afectam pequenosruminantes na China.

  4. Zona endémica de Theileria sp. na RP China • Geographic distribution of Theileria sp. (China) in the northwest part of the People’s Republic of China. Endemic area surrounded in black.

  5. Tarefas do IBET no ADDAV Developed tasks: • Participation in the infection process and in serum/blood • collection • Infected blood characterisation by PCR • and Reverse line blot (RLB) technique. • Merozoites isolation and purification studies as well as • identification of potential antigens. • Antigens characterisation by mass spectrometry • Establishment of In vitro cultivation of • Theileria sp. (China) merozoites • in erythrocytes

  6. Treino de pessoal • Coolaboração na preparação do “Workshopin Biochemical & Molecular Biology Techniques” para estudantes Chineses. • Lanzhou - 12-26 June 2002 • Joana Miranda (PhD Student) tem realizado numerosas visitas ao Lanzhou Veterinary Research Institute – Lanzhou, República Popular da China, onde desenvolveu trabalho experimental relativo a parasita Theileria sp., sob a supervisão do Prof. Yin Hong), nomeadamente para recolha de amostras de soro e sangue ovino, isolamento de merozoites, purificação de RNA e produção de cDNA, e desenvolvimento e validação de teste de ELISA • Junho 2002 e Abril-Maio 2005
