    • The invention discloses a method for producing a single bacterial strain culture of Histomonas meleagridis (H. meleagridis), the method being characterised by the following steps:
      (a) providing a xenic culture of H. meleagridis comprising H. meleagridis cells with a wild type bacterial flora,
      (b) treating the xenic culture with a mixture of antibiotics thereby killing the wild type bacterial flora,
      (c) centrifuging and washing the H. meleagridis cells,
      (d) controlling effectiveness of step (b),
      (e) resuspending the washed H. meleagridis cells,
      (f) adding one or more single bacterial strain(s) to the resuspended H. meleagridis cells, and
      (g) culturing the one or more single bacterial strain(s) with the resuspended H. meleagridis cells so as to obtain a single bacterial strain culture of H. meleagridis.
      The invention further discloses a vaccine formulation consisting of a Histomonas component consisting of an attenuated culture of Histomonas meleagridis, a bacterial component consisting of one or more cultures of a single bacterial strain, and pharmaceutically acceptable non-biological formulation compounds.
    • 本发明公开了一种用于生产嗜热Histomagasis(H. meleagridis)的单一细菌菌种培养物的方法,该方法的特征在于以下步骤:(a)提供包含具有野生型的幽门螺杆菌细胞的黑曲霉的黑色素培养物 细菌菌群,(b)用抗生素混合物处理xenic培养物,从而杀死野生型细菌菌群,(c)离心和洗涤幽门螺杆菌细胞,(d)控制步骤(b)的有效性,(e)重悬 (f)将一种或多种单一细菌菌株加入重悬的嗜酸性粒细胞中,和(g)用重悬的幽门螺杆菌细胞培养一种或多种单个细菌菌株 从而获得H. meleagridis的单一菌株培养物。 本发明还公开了一种由Histomonas组分组成的疫苗制剂,由Histomonas meleagridis的减毒培养物组成,由单一细菌菌株的一种或多种培养物组成的细菌组分和药学上可接受的非生物制剂化合物组成。
