The present disclosure provides mutant parasites, in particular protozoan parasites comprising a mutation of the trehalose-6-phosphate synthase/6-phosphate phosphatase (TPS/TPP)-like gene of Toxoplasma gondii (herein referred to as Toxoplasma) or a homologue thereof as well as vaccines comprising same.

A fermenter can have at least one hollow fluid conduit disposed at least partially within a vessel. An external circumference of the hollow fluid conduit and an interior circumference of the vessel can define a downward flow path through which a multi-phase mixture including a liquid media and compressed gas substrate bubbles flows. An interior circumference of the hollow fluid conduit can defined an upward flow path which is in fluid communication with the downward flow path. The multi-phase liquid can flow through the upward flow path and exit the fermenter. Cooling may be provided in the hollow fluid conduit or the vessel. One or more backpressor generators can be used to maintain a backpressure on the fermenter. One or more fluid movers can be used to variously create an induced and/or forced flow in the downward and upward flow paths.

A strain of ciliated protozoan is provided, which has an obvious promoting effect on germination and growth of plant seeds. The ciliated protozoan is Colpoda sp. JH2-5-4, with preservation number of CCTCC NO.C202229. After collecting over 2,000 Colpoda strains from soils across China, the present invention has screened and selected a highly efficient and active strain suitable for use as a microbial fertilizer in plant cultivation. The selected ciliated protozoan can significantly shorten the germination time of plant seeds and improve seedling survival rate.

A bag assembly for use with a heat exchanger includes a flexible bag having of one or more sheets of polymeric material, the bag having a first end that bounds a first compartment and an opposing second end that bounds a second compartment, a support structure being disposed between the first compartment and the second compartment so that the first compartment is separated and isolated from the second compartment. A first inlet port, a first outlet port, and a first drain port are coupled with the flexible bag so as to communicate with the first compartment. A second inlet port, a second outlet port, and a second drain port are coupled with the flexible bag so as to communicate with the second compartment.

The invention refers to a process for the production of a continuous cell line of simile embryo stem cells, such as Amblyomma sculptum (Acari: Ixodidae), known as line IBU/ASE-16 (access number with CNCM: 1-5000) and its uses. More specifically, the invention refers to a process for the production of the line IBU/ASE-16 and their use for obtaining extracts for the production of vaccines and candidate recombinant proteins for biopharmaceuticals and acaricides, production of diagnostic kits for the detection of antigens and/or antibodies for animal and human use, obtaining clones for use in genotyping and use as a substrate for the isolation and culture of pathogens.

The present invention relates to new protein compositions, methods for producing said protein compositions, pharmaceutical compositions comprising said protein compositions and methods for treating infections caused by Neospora caninum. In particular, the present invention relates to a protein composition comprising the proteins specified in Table A in an amount of at least about 2 times (fold change) higher than the same protein present in the whole tachyzoite, as calculated by quantitative label-free liquid chromatography-tandem mass spectrometry (LC-MS/MS).

Improved labyrinthulomycetes strains that produce microbial oils having increased docosahexaenoic acid (DHA) content are disclosed. The strains have increased productivity with respect to a wild type strain. Also provided are microbial oil compositions having increased DHA content. Methods of improving strains for the production of lipid, such as DHA, are also included.
