The invention relates to isolated recombinant analogues of flavivirus E-protein fusion loops comprising at least one glycosylation site for an N-linked glycan that is not present in the natural flavivirus E-protein fusion loop sequence, wherein the at least one glycosylation site is an N-linked glycosylation sequon (Asn-X-Ser/Thr) and the Asn (N) residue of the sequon occupies any of positions 98-110 (SEQ ID NO: 1) (DRGWGNGCGLFGK) of the natural flavivirus E-protein fusion loop amino acid sequence, wherein X is any amino acid residue except proline and Ser/Thr denotes a serine or threonine residue.

The disclosure provides methods, biomarkers, and kits for determining the prognosis of Zika virus infection in relation to severity of symptoms resulting from effects of the Zika virus infection on bone metabolism, such as arthralgia, osteoporosis, and craniosynostosis. The disclosure further provides treatments for Zika virus infection, in particular for treating arthralgia, osteoporosis, and craniosynostosis.

The invention provides enrichment platform devices for size-based capture of particles in solution. The enrichment platform device is useful for label-free capture of any particle. The invention relates to enrichment platform devices using nanowires and vertically aligned carbon nanotubes. The invention provides methods for making the enrichment platform devices. The invention provides methods for using the enrichment platform devices for filtering particles, capturing particles, concentrating particles, and releasing viable particles.

The invention provides an agent for the treatment or prevention of viral infection in a subject. The agent is preferably a compound of Formula (I)

##STR00001##

wherein R.sup.1-R.sup.11, X, Y and Q are as defined herein. Also provided are pharmaceutical compositions and combinations comprising such agents. An in vitro method of evaluating the antiviral activity or potential antiviral activity of a compound against a virus is also provided.

The present invention provides a stable synthetic saccharide of Hib polyribosylribitol-phosphate (PRP) derivative and conjugate thereof. Said saccharide, said conjugate and pharmaceutical compositions thereof are hydrolysis-resistant, long-term stable and useful for the prevention and/or treatment of diseases associated with Haemophilus influenzae, and more specifically of diseases associated with Haemophilus influenzae type b, preferably diseases selected from meningitis, pneumonia, and epiglotitis. They have general formula (I): wherein A is formula (II) or formula (III); B is formula (IV); C is formula (V); D is formula (VI); E is formula (VII); F is formula (VIII) or formula (IX).

Disclosed herein are systems and methods for detecting and diagnosing flaviviral or alphaviral infections in subjects in need thereof. The systems and methods of the disclosure enable rapid testing of small volumes of biological sample with the ability to reliably distinguish between flavival and alphaviral infections and determine whether the viral infection is acute or chronic.

Described herein are single-domain antibodies that might serve as alternatives to conventional monoclonal antibodies for either the detection or treatment of Chikungunya Virus (CHIKV).

This disclosure provides antibodies and antigen-binding fragments that are derived from 3bgf and that can be administered to an individual that is infected or suspected of being infected with a virus. Antibodies and antigen-binding fragments herein can be capable of treating or curing the virus, and which may provide protection against the virus for up to several weeks. Antibodies and antigen-binding fragments herein can be used to diagnose a SARS CoV-2 infection.

This disclosure provides antibodies and antigen-binding fragments that are derived from 2dd8 and that can be administered to an individual that is infected or suspected of being infected with a virus. Antibodies and antigen-binding fragments herein can be capable of treating or curing the virus, and which may provide protection against the virus for up to several weeks. Antibodies and antigen-binding fragments herein can be used to diagnose a SARS CoV-2 infection.

This disclosure provides superhuman antibodies and antigen-binding fragments that can be administered to an individual that is infected or suspected of being infected with a virus. Superhuman antibodies and antigen-binding fragments provided herein can be capable of treating or curing the virus, and which may provide protection against the virus for up to at least several weeks. Superhuman antibodies and antigen-binding fragments provided herein can be used to diagnose a SARS Cov-2 infection.
