The purpose of the present invention is to provide a specific antibody applicable to immunochromatographic detection of Mycoplasma pneumoniae infections, and a detection reagent using the same, among others. Provided are a Mycoplasma pneumoniae detection reagent and kit that include a specific antibody against the P30 protein of Mycoplasma pneumoniae, and an immunochromatographic test device.

A new non-HIV vaccine antigen from Mycoplasma sp. permease capable of inducing a mucosal neutralizing protective antibody response against HIV infection, a neutralizing antibody directed to said antigen, and a method for the identification of new antigens from the mucosal microbiota for the development of vaccines against pathogens.

[Problem]

An object of the present invention is to provide a detection marker that can simply and rapidly detect Mycoplasma pneumoniae, which is a pathogen of mycoplasma pneumonia, at a high sensitivity, a specific antibody against the marker, and also an immunological detection method and a kit containing the antibody.

[Solution]

Infection with Mycoplasma pneumoniae can be rapidly and specifically diagnosed by producing an antibody specifically reactive to P30 protein of Mycoplasma pneumoniae and performing an immunological assay using the P30 protein as a detection marker. The present invention enables easy and rapid detection of Mycoplasma pneumoniae and diagnosis of infection with the bacteria at a hospital or the like without need of specialized instruments or skilled techniques.

Provided herein are compositions and methods for detection of detection and treatment of Mycoplasma haemofelis and Mycoplasma haemocanis.

The present invention encompasses methods and compositions for Ureaplasma infection prevention and/or treatment. In specific cases, the invention concerns vaccines for Ureaplasma, including DNA vaccines. In certain embodiments, the invention regards vaccines directed towards the multiple-banded antigen(s) of Ureaplasma.

Disclosed is a novel method of detecting a test subject by an immunoassay, in which low sensitivity due to using a monoclonal antibody is improved in spite of using a monoclonal antibody in the immunoassay. The method of detecting a test subject is a method of detecting a test subject having two or more kinds of antigens which enable detection of said test subject, which method is performed by an immunoassay such as a sandwich method, using a monoclonal antibody or an antigen-binding fragment thereof which recognizes the two or more kinds of antigens.

In certain embodiments, the invention regards vaccines directed towards the multiple-banded antigen(s) of Ureaplasma.

Provided herein methods of alleviating the symptoms of multiple myeloma in a patient or subject in need thereof, methods of treating multiple myeloma in a patient or subject, and methods of preventing development of multiple myeloma in a patient at risk thereof, such as a patient with monoclonal gammopathy of undetermined significance (MGUS), which methods include administering an agent effective to treat a Mycoplasma infection. The invention also relates to a new class of antigen, MG281 protein {also referenced as Protein M), that binds to various immunoglobulins with high affinity, and their uses in purifying immunoglobulins. The invention additionally relates to using MG281 protein and analog or derivative molecules for treating autoimmune diseases. Further provided are antigens and antibodies for use in the disclosed methods, and the identification of molecules that bind to MG281 protein.

Antibodies that detect M. hyopneumoniae, methods of making those antibodies, and methods of using those antibodies including, for example, in a diagnostic immunoassay, are described. Such a diagnostic assay may be used in pen-side testing for detection of M. hyopneumoniae.
