This document relates to conjugates of a biologically active molecule or a derivative thereof and functionalized (e.g., mono- or bi-functional) polymers (e.g., polyethylene glycol and related polymers) as well as methods and materials for making and using such conjugates.

The present invention relates to assays, kits and oligonucleotides for the detection of Pseudomonas aeruginosa for a fast, sensitive and reliable detection of Pseudomonas aeruginosa in a species- and serotype-specific manner. In particular, the present invention provides an assay for the serotype-specific detection of Pseudomonas aeruginosa, a kit for the serotype-specific detection of Pseudomonas aeruginosa, as well as oligonucleotides useful in such assay or kit. The present invention further relates to the use of Pseudomonas aeruginosa serotype specific antibodies for serotype specific treatment of Pseudomonas aeruginosa infection in a patient detected for said specific Pseudomonas aeruginosa serotype with such an assay or kit.

The present invention provides methods, compositions and articles of manufacture useful for the prophylactic and therapeutic amelioration and treatment of gram-positive bacteria, including Streptococcus and Staphylococcus, and related conditions. The invention provides compositions and methods incorporating and utilizing Streptococcus suis derived bacteriophage lysins, particularly PlySs2 and/or PlySs1 lytic enzymes and variants thereof, including truncations thereof. Methods for treatment of humans are provided.

The present invention relates to a polypeptide comprising a Gram negative endolysin and a peptide selected from the group consisting of an antimicrobial peptide, an amphipathic peptide, a cationic peptide, a sushi peptide or a defensin, wherein the endolysin in turn is selected from the group consisting of SEQ ID NO:1, SEQ ID NO:2, SEQ ID NO:3, SEQ ID NO:4, SEQ ID NO:5, SEQ ID NO:6, SEQ ID NO:7, SEQ ID NO:8, SEQ ID NO:9 and sequences having at least 80% sequence identity with SEQ ID NO:1, SEQ ID NO:2, SEQ ID NOG, SEQ ID NO:4, SEQ ID NOG, SEQ ID NO:6, SEQ ID NO:7, SEQ ID NO:8 and/or SEQ ID NO:9. The present invention relates also to corresponding nucleic acids, vectors, bacteriophages, host cells, compositions and kits. The present inventions also relates to the use of said polypeptides, nucleic acids, vectors, bacteriophages, host cells, compositions and kits in methods for treatment of the human or animal body by surgery or therapy or in diagnostic methods practiced on the human or animal body. The polypeptides, nucleic acids, vectors, bacteriophages, host cells, compositions and kits according to the invention may also be used as an antimicrobial in, e.g., food or feed, in cosmetics, or as disinfecting agent.

Provided are animal feed or animal feed additives comprising one or more polypeptides having lysozyme activity. Provided are polypeptides having lysozyme activity, polynucleotides encoding the polypeptides nucleic acid constructs, vectors, and host cells comprising the polynucleotides as well as methods of producing and using the polypeptides.

The present invention relates to a composition and/or an animal feed comprising polypeptides having muramidase activity and essential oils and uses thereof.

Provided herein are a vector, a genetically modified bacterium including the vector, methods of making the bacterium, methods of using the bacterium, and kits including the bacterium. The vector includes a coding region encoding at least one antimicrobial peptide, and the antimicrobial peptide includes at least one lysin.

Provided are: an economically superior protein crystallization method capable of efficiently finding conditions for crystallization by using a small amount of protein; and a crystallization device used for the method. According to the present invention, a transparent sealed container 1 is filled with a solution of protein, a part of the transparent sealed container 1 being formed of a semipermeable membrane 2 with a molecular weight cut-off that inhibits passage of the protein while allowing passage of a precipitant, and then, a precipitant solution with changed concentration and/or pH of the precipitant is continuously supplied to the semipermeable membrane 2, to crystallize the protein with the precipitant that infiltrates from the semipermeable membrane 2 into the sealed container 1.

The present invention relates to a composition and/or an animal feed comprising polypeptides having muramidase activity and polypeptides having protease activity and uses thereof.

The application relates to antimicrobial agents against Gram-negative bacteria, in particular to fusion proteins composed of an enzyme having the activity of degrading the cell wall of Gram-negative bacteria and a peptide stretch fused to the enzyme at the N- or C-terminus, as well as pharmaceutical compositions comprising the same. Moreover, it relates to nucleic acid molecules encoding such a fusion protein, vectors comprising said nucleic acid molecules and host cells comprising either said nucleic acid molecules or said vectors. In addition, it relates to such a fusion protein for use as a medicament, in particular for the treatment or prevention of Gram-negative bacterial infections, as diagnostic means or as cosmetic substance. The application also relates to the treatment or prevention of Gram-negative bacterial contamination of foodstuff, of food processing equipment, of food processing plants, of surfaces coming into contact with foodstuff, of medical devices, of surfaces in hospitals and surgeries.
