Methods to edit genes by administering a chimeric nuclease to a cell or organism without the use of a viral vector.

Disclosed is a method for identifying methicillin-resistant Staphylococcus aureus through detection a mass signal at m/z of 6580-6600 in the MALDI-TOF mass spectrum. Also disclosed is a novel peptide biomarker, which consists of SEQ NO ID:5 and the use thereof for detection and/or identification of methicillin-resistant Staphylococcus aureus.

Improved methods are provided for preparing synthetic microorganisms, recombinant microorganisms, live biotherapeutic products (rLBPs), and compositions thereof The synthetic microorganisms exhibit functional stability over at least 500 generations and are useful for treatment, prevention, and/or prevention of recurrence of microbial infections.

Disclosed are SaCas9 protein variants, constructs encoding such variants, compositions comprising such variants and constructs, and methods of using the variants, constructs, and compositions. In some forms, the disclosed variants comprise the mutation Y239H and do not comprise the mutation R245A. Also disclosed are constructs encoding any of the disclosed variants for expression of the variant in a host of interest. Also disclosed are methods of editing a sequence of interest.

Live biotherapeutic compositions and methods are provided for treatment, prevention, or prevention of recurrence of skin and soft tissue infections, such as mastitis and/or intramammary infections, for example, in cows, goats, sows, and sheep. Methods include decolonizing and durably replacing with a live biotherapeutic composition comprising a synthetic microorganism that may safely and durably replace an undesirable microorganism under dermal, mucosal, or intramammary conditions.

An affinity support having improved binding capacity for target proteins. An immunoglobulin-binding protein including a mutant immunoglobulin-binding domain, an affinity support including a solid-phase support and the immunoglobulin-binding protein immobilized thereto. The mutant immunoglobulin-binding domain consists of an amino acid sequence having at least 85% identity with an amino acid sequence of any of SEQ ID NOs: 1 to 12.

The present invention relates to a vaccine composition comprising a Staphylococcus aureus attenuated enterotoxin protein and cytotoxin protein, and more particularly to a Staphylococcus aureus enterotoxin protein, a Staphylococcus aureus cytotoxin protein, a vaccine composition for prevention of bovine mastitis, comprising the Staphylococcus aureus enterotoxin protein and Staphylococcus aureus cytotoxin protein and a method for preventing bovine mastitis comprising administering the vaccine composition to a bovine. The Staphylococcus aureus enterotoxin protein, the Staphylococcus aureus cytotoxin protein according to the present invention, and the vaccine composition comprising the proteins as an antigen can be used so that even vaccines comprising several antigens rather than all kinds of antigens show the excellent effects of prevention and treatment of bovine mastitis against all kinds of Staphylococcus aureus enterotoxin and cytotoxin having high incidence in Korea, thereby being more economically used for industrial purposes. Further, the vaccine composition for prevention of bovine mastitis, comprising the Staphylococcus aureus enterotoxin protein and Staphylococcus aureus cytotoxin protein according to the present invention has an excellent safety and bovine mastitis prevention and treatment effect even in the high CFU Staphylococcus aureus challenge test so that the composition can be variously utilized in Staphylococcus aureus vaccine and prevention related fields in future.

The present invention relates to a primer set for detecting food poisoning bacteria by using a next-generation sequencing method and a method for detecting food poisoning bacteria by using the primer set. Specifically, with the primer set in accordance with the present invention, 16 kinds of food poisoning bacteria can be detected at one time, for a shorter time, and with high accuracy, and the primer set can be useful for simultaneous detection of food poisoning bacteria.
