The present disclosure provides a biological control method for ciliate disease, and belongs to the technical field of biological control. The biological control method includes the following step: adding Chaenea vorax into an aquaculture pond to control the ciliate disease; and the Chaenea vorax includes Chaenea vorax PJ13002. According to the present disclosure, the Chaenea vorax PJ13002, a predatory protozoan, is introduced to recover a microbial food chain existing in nature in an aquaculture system and achieve biological control of the ciliate disease. Meanwhile, the Chaenea vorax PJ13002 can be directly ingested by aquaculture animals without causing diseases, so that a more stable aquaculture system can be formed, losses are avoided, costs are reduced, and economic benefits are increased. The method provides a new thought for controlling the ciliate disease and has an excellent popularization and application prospect.

The present invention relates to an oil of microorganisms rich in docosahexaenoic acid (DHA, C22:6n3), comprising more than 60% of DHA relative to the total mass of fat and to the use thereof for human or animal feed, in particular for feeding infants, children, or pregnant or lactating women.

The present invention relates to a vaccine composition comprising a host cell belonging to the genus Leishmania, wherein the host cell comprises a polynucleotide coding for at least one protein of a virus belonging to the family Coronaviridae. Furthermore, the invention relates to the medical and veterinary use of the vaccine composition and to a process for preparing the vaccine composition.

The present disclosure relates to compositions and methods for inducing encystment of and/or stabilising ciliate cells. In particular, the present disclosure relates to polymers and polymeric solutions, including hydrocolloids, which may be used to induce encystment of trophont ciliate cells to form encysted ciliate cells and/or stabilise encysted cells. The present disclosure also relates to methods of infecting and/or colonising molluscs with the compositions and ciliates described herein.

The present invention relates to recombinant cells and microorganisms of the phylum Labyrinthulomycota and their use in heterologous protein production. Novel promoter, terminator, and signal sequences for efficient production and, optionally, secretion of polypeptides from recombinant host cells and microorganisms are also encompassed by the present invention.

A method of using a strain of ciliated protozoan for promoting effect on germination and growth of plant seeds is provided. The ciliated protozoan is a Colpoda species JH2-5-4, with preservation number of China Center for Type Culture Collection (CCTCC) NO. C202229. A method of screening and selecting a highly efficient and active strain suitable for use as a microbial fertilizer in plant cultivation is provided. The selected ciliated protozoan strain shortens the germination time of plant seeds, promotes plant growth, and improves seedling survival rate.

The present invention describes methods of identifying high-risk populations or individuals who have positive serology for T.gondii. These methods include obtaining a biological sample from a subject; determining the level of T.gondii cyst antigen antibody in the biological sample; and characterizing the biological sample in at least one of three categories.

Described herein are compositions and methods of producing glycosylated proteins in vitro and in vivo. The methods include using host cells to produce glycosylated proteins. Also described herein are glycosylated proteins produced using such methods and uses thereof.

The present invention is directed to isolated microorganisms as well as strains and mutants thereof, biomasses, microbial oils, compositions, and cultures; methods of producing the microbial oils, biomasses, and mutants; and methods of using the isolated microorganisms, biomasses, and microbial oils.

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.
