The invention is directed to a culture medium for Haematococcus that contains combustion gases like carbon dioxide, carbon monoxide, and oxides of nitrogen or sulfur and which fixes the carbon, nitrogen or sulfur in these combustion gases into biomass and to methods providing superior biomass yields using this culture medium to culture select species of Haematococcus such as Haematococcus sp. KAU-01.

The present invention relates to the field of antigen binding proteins and the use of such antigen binding proteins in an assay. More particularly, it relates to antigen binding proteins which bind to an epitope of Protein E and antigen binding proteins which bind to an epitope of PilA. The present invention also relates to assays (particularly in vitro assays) for assessing binding to Protein E and/or PilA and the potency of vaccines containing Protein E and/or PilA. In particular the invention relates to in vitro relative potency assays used in the release of a vaccine to the public.

The present invention provides a real-time PCR method that allows in a single step the simultaneous detection of etiological agents of bacterial meningitis, more specifically, Neisseria meningitidis, Streptococcus pneumoniae and Haemophilus influenzae. For this, primers were used to amplify particular regions of the genomes of said bacteria. The presence of bacteria in a sample is indicated by the presence of amplicon, which is detected by means of detection methods appropriate to the PCR methodology employed.

Gram-negative bacterial strains are generated by inactivating at least one LytM catalytic domain-containing protein, such as NT013, NT017 and NT022 of non typeable H influenzae. The vesicles from these strains are useful for vaccination.

NTHI protein antigens have been identified and found to be conserved across several Haemophilus influenzae pathogenic strains. They have been isolated, cloned from a reference strain and tested for immunogenicity. Methods for immunization and vaccines derived thereof are also disclosed.

Provided herein are methods, compositions, and systems for treating dental caries and a periodontal disease based on microbiome modulation through oral microbiome transplant (OMT). The original oral microbial composition was obtained from the dental plaque of healthy donors, and then modulated by growing a biofilm in vitro in a growth medium. The modulated oral microbial composition has a different microbial diversity than the original oral microbial composition. In the modulated oral microbial compositions, the abundance of some bacterial species changes, some new bacterial species are present, and some original bacterial species are no longer present. The modulated oral microbial composition is transplanted to the recipient's oral cavities through OMT to treat dental caries or a periodontal disease.
