Methods and compositions are provided for modulating expression of a target nucleic acid sequence within a non-E. coli cell. The method includes providing the cell with a guide RNA comprising a portion that is complementary to all or a portion of the target nucleic acid sequence, and providing the cell a Cas protein, wherein the guide RNA and the Cas protein co-localize at the target nucleic acid sequence and wherein the Cas protein modulate the expression of the target nucleic acid sequence.

In certain embodiments, the present invention provides a DNA nanostructure nanorobot comprising: a single stranded DNA scaffold strand of about 5,000 to 10,000 bases in length; a plurality of staple strands of DNA, wherein each staple strands are about 20 to 40 bases in length, wherein each staple strand has a unique sequence and is hybridized to a specific position on the DNA scaffold strand, wherein the plurality of staple strands hybridized to the DNA scaffold form a sheet having a top surface and a bottom surface; and one or more fastener strands of DNA, wherein the one or more fastener strands of DNA is capable of fastening the sheet into an origami structure.

Bacteriophage against Geobacillus are provided, and methods of making and using the bacteriophage also are provided.

The present invention relates to the field of structural biology. More specifically, the present invention relates to novel antigen-binding chimeric proteins, their uses and methods in three-dimensional structural analysis of macromolecules, such as X-ray crystallography and high-resolution Cryo-EM, and their use as a therapeutic, diagnostic, or imaging tool. Even more specifically, the invention relates to a fusion of a scaffold protein and an antigen-binding domain wherein the scaffold protein of said fusion interrupts the Immunoglobulin domain topology to form a rigid chimer.

Bacteriophage are provided, and methods of making and using the bacteriophage also are provided.

The present invention describes applications and methods to use (1) recombinant Xanthomonas phages (phiXfu, Xfv, Xfr, fXa, phiXca), and their variants to prevent and eradicate the Xanthomonas pathogens causing black rot, bacterial blight, bacterial leaf spot, bacterial blight of bean, sugarcane leaf scald, cassava bacterial blight, etc. (2) recombinant Xylella phages (fXy1, fXy2, fXy3, fXy4, fXy5, fXy6, fXy7, fXy8, fXy9, and fXy10) and their variants to prevent and eradicate Xylella fastidiosa, which causes olive quick decline syndrome (OQDS), Pierce's disease (grape), phoney peach disease, bacterial leaf scorch, oleander leaf scorch, citrus variegated chlorosis disease, and so on.

Provided are compositions and methods for treating, ameliorating and preventing infections, disorders and conditions in mammals, including genetically-predisposed and chronic disorders, where a microbial or bacterial flora is at least one causative or symptom-producing factor. Provided are compositions and methods used to treat, prevent or ameliorate an infection, for example, an infection in the gastrointestinal tract, or bowel. Provided are compositions and methods for treating, ameliorating and/or preventing a condition comprising an abnormal, disrupted or pathological mucosal surface or mucus-covered epithelium, or a condition caused, modified or effected by an abnormal, disrupted or pathological microbiotia, wherein optionally the infection or condition comprises a diarrhea, a colitis, obesity, diabetes, autism, a cystic fibrosis, a dysentery, a gastrointestinal infection, a gastrointestinal inflammation, a gastrointestinal dysbiosis, a gastrointestinal upset, a lung infection, a bacterial infection, a viral infection, a secondary infection, an inflammation, a mucus hypersecretion, or a dysbiosis.

A method for producing one or more hybrid bacteriophage host range determinant (HRD) sequences, which comprises: (1) identifying at least two DNA sequences, each encoding an HRD in a series of regions in the DNA sequence, wherein the HRDs are different from one another, (2) incorporating each region into a vector in which each region is flanked by a recognition site of a restriction enzyme capable of cutting DNA at a specific cleavage site outside of the recognition sequence, so that the cleavage site of the restriction enzyme is situated at the boundary of each region, wherein the cleavage site sequences of the regions from an individual series are different from one another and wherein the cleavage site sequences at the boundaries of corresponding regions from different series are the same; (3) treating the vectors with a restriction enzyme capable of cutting DNA at a specific cleavage site outside of the recognition sequence so as to generate a mixture of the regions; and (4) treating the mixture of the regions with a ligase to ligate them to form an array of DNA sequences encoding an array of hybrid HRDs.
