Methods for detecting a mycobacterial infection in a patient are disclosed. These methods include the step of detecting lipoarabinomannan (LAM) and/or derivatives thereof in a biological sample from the patient. Methods for diagnosing disease, including nontuberculous mycobacterial infection (NTM), and kits for the described methods are also provided.

A TCR-like antibody or an antigen-binding fragment thereof, the antibody binding to and having specific and improved affinity to an MHC-I molecule, particularly a CMV pp65 peptide complex (CMVP495-503/HLA-A*02:01) presented by HLA-A*02 are disclosed. A nucleic acid for coding the TCR-like antibody or the antigen-binding fragment thereof; an expression vector containing the nucleic acid; a cell transformed to the expression vector; a method for producing same; a composition containing a T cell for expressing the antibody or the antigen-binding fragment thereof as a chimeric antigen receptor; uses of the composition in preventing or treating cancer or an infectious disease; uses of the composition in diagnosis; methods for preventing and/or treating cancer or infectious diseases; and methods for diagnosing are disclosed.

Disclosed herein is a recombinant antibody exhibiting binding affinity and/or neutralizing activity to porcine epidemic diarrhea virus (PEDV). According to some embodiments of the present disclosure, the PEDV is genotype 1 (G1) or genotype 2b (G2b) PEDV. Also disclosed herein are methods of diagnosing and treating PEDV infection by use of the present recombinant antibody.

The present disclosure provides a method of detecting the presence of a hypnozoite stage of Plasmodium vivax in a liver cell. In addition, the present disclosure provides compositions and methods of detecting the presence of a latent Plasmodium vivax infection in a subject and for treating the subject detected to be infected.

The present invention provides biomarkers allowing the diagnosis of symptomatic congenital cytomegalovirus (CMV) infection and in particular to differentiate between symptomatic and asymptomatic infected fetuses, methods of diagnosis of CMV using said biomarkers, diagnostic kits comprising thereof, and use of the kits and methods of diagnosing fetuses infected with a symptomatic congenital cytomegalovirus (CMV).

The present disclosure provides methods and compositions for determining whether a patient exhibiting acute gastroenteritis will benefit from treatment with therapeutic agents that inhibit Norovirus genogroup I (GI) or Norovirus genogroup II (GII). The methods disclosed herein are based on detecting Norovirus genogroup I (GI) and Norovirus genogroup II (GII) in a stool sample without extracting viral nucleic acids from a clinical specimen prior to performing real-time reverse transcription PCR. Kits for use in practicing the methods are also provided.

Provided herein are nucleic acid-cleaving catalytic nucleic acid probes, biosensors and lateral flow biosensor devices and methods and kits of using the probes, biosensors and lateral flow biosensor devices for detecting an analyte present on or generated from a microorganism in a test sample, including Helicobacter pylori and methods for determining whether a subject has a Helicobacter pylori infection.

The present disclosure provides compositions and methods for acidic compositions for use in optimizing the genital microbiome of a user or sexual partners of that user. The compositions may comprise a prebiotic oligosaccharide, a metal co-factor, and an essential oil comprising bornyl acetate. The compositions support the genital microbiota and are useful for, for example, hydrating, lubricating, cleaning, and/or decreasing irritation or inflammation of the urogenital and/or anogenital region of a subject, and/or enhancing the beneficial genital microbiota of a subject. Such compositions are useful before, during, and/or after sexual and/or reproductive activity. Furthermore, the compositions may have minimal or beneficial effect on gametes.

Monoclonal antibodies that specifically bind the F1 antigen of Yersinia pestis with high affinity are described. Use of the monoclonal antibodies for the detection of Y. pestis infection and the diagnosis of plague are also described. Immunoconjugates of the monoclonal antibodies and a radionuclide can also be used for the treatment of a Y. pestis infection.

The present invention relates inter alia to the treatment or prevention of influenza virus infection (including subtypes influenza A virus, influenza B virus, avian strain H5N1, A/H1N1, H3N2 and/or pandemic influenza) using compounds which inhibit the activity of p59-HCK and to a method of screening for a candidate drug substance intended to prevent or treat influenza virus infection in a subject, said method comprising identifying a test substance capable of inhibiting p59-HCK activity.
