  • Patent number: 7317094
    Abstract: The process of the invention comprises the implementation of axenic conditions, with use of a liquid single-phase culture medium. For obtaining the amastigote forms, this medium is buffered at a pH of 5.5 to 6.5 and has an osmolarity of at least 400 milliosmoles/kg of liquid, and in particular 400 to 550 milliosmoles/kg of liquid. For obtaining promastigote forms, this medium is buffered at a pH of 7 to 7.5 and has an osmolarity of at least 300 milliosmoles/kg of liquid. This process allows the adaptation and culture in vitro of different stages of tissular parasites, such as leishmanias and T. cruzi or also hematoprotozoa.

  • Patent number: 6458581
    Abstract: The present invention provides a method for carrying out in vitro the complete developmental sequence culture of tissular parasites, which includes culturing the parasites in a totally defined culture medium which is an axenic monophasic liquid culture medium, free of serum and free of serum-derived or cell-derived macromolecules, proteins and peptides. For obtaining amastigote forms, this medium is buffered at a pH of 5.5 to 6.5 and has an osmolarity of at least 400 milliosmoles/kg of liquid. For obtaining promastigote forms, the medium is buffered at a pH of 7 to 7.5 and has an osmolarity of at least 300 milliosmoles/kg liquid. Application to the in vitro culture of different stages of tissular parasites such as Leishmania, T. cruzi, and hamatoprotozoa is also provided.

  • Patent number: 6022537
    Abstract: Bacterial strains of genus Bacillus closely phenotypically related to genus Lactobacillus. The strains are moderately thermophilic, have amylolytic properties and/or are capable of producing L(+) lactate, and are useful for producing metabolites such as L(+) lactate.
