Abstract: The present disclosure belongs to the technical field of biological products for veterinary medicine, and specifically relates to a recombinant foot-and-mouth disease virus (FMDV) with a reduced immunosuppressive activity, a preparation method and use thereof, and a recombinant vaccine strain. According to the present disclosure, it is firstly discovered that FMDV 3B protein has an immunosuppressive function, and key sites for exerting the immunosuppressive function are found. A recombinant FMDV vaccine strain with a lost immunosuppressive function in FMDV 3B protein is constructed by introducing amino acid mutations into three repeated copies of FMDV 3B protein.

Abstract: The disclosure relates generally to the field of immune binding proteins and method for obtaining immune binding proteins from genomic or other sources. The disclosure also relates to anti-SARS-CoV-2 antibodies that have been obtained from subjects who became immune to this coronavirus, and to methods of using these anti-SARS-CoV-2 antibodies. Methods for neutralizing SARS-CoV-2 are disclosed, as well treatments for SARS-COV-2 using the anti-SARS-CoV-2 antibodies.

Abstract: Recombinant SARS-CoV2 vaccine compositions and methods are presented that have unexpected cross-reactivity against a variety of other coronaviruses, and particularly against SARS-CoV1, MERS-CoV, OC43-CoV, and HKU1-CoV in addition to significant reactivity against SARS-CoV2A. Moreover, the vaccine compositions presented herein also produced cross-reactive memory B cells as well as cross-reactive memory T cells with cross-reactivity spanning a relatively wide range of different coronaviruses.

Abstract: An immunogenic composition, a SARS-CoV-2 vaccine and a vector are introduced. The immunogenic composition has a recombinant protein having a sequence selected from the group consisting of SEQ ID NO: 1, SEQ ID NO: 2, SEQ ID NO: 3, SEQ ID NO: 4, and any polypeptide encoded by a polynucleotide which is at least 80% homologous with SEQ ID NO: 1-4, wherein the recombinant protein contains an IgG1 Fc protein fragment having a length of at least 6 amino acids; or a nucleic acid molecule encoding the recombinant protein. The SARS-CoV-2 vaccine has the above recombinant protein or the nucleic acid molecule encoding the above recombinant protein. The vector has the nucleic acid molecule encoding the above recombinant protein.

Abstract: Provided is a method and composition using ROS to increase the production of bacteriophage. According to the subject matter, a production amount of bacteriophage is increased several times in the presence of the sublethal concentration of ROS for host bacteria. Therefore, the method and composition of the subject matter can be useful for producing bacteriophage, which is used as an alternative to antibiotics that cause a serious resistance problem.

Abstract: In some aspects, the disclosure relates to compositions and methods for production of recombinant adeno-associated virus (rAAV) particles. The disclosure is based, in part, on isolated nucleic acids and systems that include only two vectors and are suitable for production of multiple different single gene viral vectors in a multiple small-scale campaign mode (e.g., 1013 to 1016 viral particles.

Abstract: The present disclosure is directed to antibodies binding to and neutralizing Chikungunya virus (CHIKV) and methods for use thereof.

Abstract: The present invention relates to a Myoviridae bacteriophage Aer-HYP-3 (Accession number: KCTC 13479BP) isolated from nature, which has the ability to kill Aeromonas hydrophila bacteria and has the genome represented by SEQ ID NO: 1, and to a method of preventing and treating a disease caused by Aeromonas hydrophila bacteria using a composition containing the same as an active ingredient.

Abstract: An antibacterial formulation having a mixture of bacteriophages with lytic activity against strains of Salmonella spp. and a pharmaceutically and veterinarily acceptable vehicle, pH stabilizer and/or excipients. This formulation is for the prevention and treatment of infectious diseases caused by Salmonella spp. and different serovars; use and method for preventing or treating infectious diseases caused by Salmonella spp. in farm animals by administering the antibacterial formulation to a non-human animal orally.

Abstract: The present application provides a bispecific antibody against rabies virus, and an application thereof. The bispecific antibody comprises two antigen-binding fragments binding to different epitopes of G protein of rabies virus, and has rabies virus neutralization activity.

Abstract: A vaccine candidate is herein described comprised by statistically significant DNA fragments related to Civet SARS, Bat Sars, and BtRs BetaCov, BtRI BetaCov, and Neoromicia resulting in three types of compositions: 1) a composition of statistically significant DNA fragments, 2) a composition of RNA transcripts corresponding to the statistically significant DNA fragments, and 3) a computational reduction composition wherein the DNA fragments are fully or partially subtracted from a base organism, resulting in a synthetic organism which has a high statistical likelihood of problematic functions being partially or fully removed.

Abstract: The present disclosure provides methods for the separation and quantification of empty and full viral capsids (e.g., AAV capsids) within a viral preparation, such as a viral pharmaceutical composition or drug product.
