The present invention includes a liquid sanitization device including one or more light emitting diodes (LED) that emit electro-magnetic radiation primarily at two or more distinct wavelengths. These wavelengths should be less than about 300 nm, preferably between about 210 to about 300 nm. The radiation from the light emitting diode or diodes kills or interacts with the DNA or RNA of pathogenic organisms in the liquid to prevent the organisms from reproducing or harming desirable organisms.

The present invention is a centralized system for the automated monitoring and reporting of compliance to infection prevention policies. It is focused on the proactive reduction (elimination) of pathogenic organisms causing infection within the facility by enforcing best practices for infection prevention.

The inventions of the present disclosure are directed to processes designed to recover water used in certain aspects of the processing of poultry, treat the recovered water to remove solids, fats, oils and greases, animal proteins and pathogenic organisms and to reuse the treated water for poultry processing operations. The processes described herein reduce bacteria and microorganisms associated with the poultry and reuse water. The present disclosure can be employed with an approach that includes unexpected positive results of reacting ozone and chlorine with water being treated for reuse to generate hypochlorous acid and / or other effective biocides. Ozone reacts with fats, oils, and greases, dissolved in the reuse water, to produce specific surface-active agents and surfactants which reduce the surface tension of the water which it is dissolved. The combination of these surface-active agents and surfactants and the biocides cause an extraordinary release and destruction of bacteria from the poultry carcass as well as the reuse water.

Disclosed are oligonucleotide amplification primers and detection probes specific for the amplification and detection of pathogenic organisms, including for example, specific Influenza A H1N1 viral isolates. Also disclosed is a biological organism identification kit including the disclosed nucleic acid probes and primers, as well as thermal cycling reagents that is both portable and durable, and may also be self-contained for remote, or in-field analysis and identification of particular influenza isolates from a variety of biological specimen types.

This invention is directed to processes designed to recover water used in certain aspects of the processing of poultry, treat the recovered water to remove solids, fats, oils and greases, animal proteins and pathogenic organisms and to reuse the treated water for poultry processing operations. Although the reuse points will vary from plant to plant depending upon specific water consumption volumes, type of processing operations conducted by the facility and regulatory requirements and approvals, there are a number of reuse points which are preferred based upon treated water quality requirements, material balances relating to the capacity to recover process streams and the consumption volumes at the identified reuse points, and source waters that have been shown to have the least total contaminant loading.

Non-hemolytic cytolytic agents selected from peptides, complexes of bundled peptides, mixtures of peptides or random peptide copolymers have a selective cytolytic activity manifested in that they have a cytolytic activity on pathogenic cells, being cells which are non-naturally occurring within the body consisting of microbial pathogenic organisms and malignant cells; and are non-hemolytic, having no cytolytic effect on red blood cells. The peptides may be cyclic derivatives of natural peptides such as pardaxin and mellitin and fragments thereof in which L-amino acid residues are replaced by corresponding D-amino acid residues, or are diastereomers of linear peptides composed of varying ratios of at least one positively charged amino acid and at least one hydrophobic amino acid, and in which at least one of the amino acid residues is a D-amino acid. Pharmaceutical compositions comprising the non-hemolytic cytolytic agents can be used for the treatment of several diseases caused by pathogens including antibacterial, fungal, viral, mycoplasma and protozoan infections and for the treatment of cancer.

Lipophilic conjugates comprise a peptide coupled to a fatty acid The peptide comprises at least two positively charged amino acid residues; the peptide after conjugation to the fatty acid possessing antibacterial, antifungal, and / or anticancer activity higher than prior to conjugation. The lipophilic conjugates are suitable for treatment of infections caused by pathogenic organisms such as bacteria and fungi. The lipophilic conjugates are also suitable for sanitation, as disinfectants, or for food preservation.

The present invention provides methods and compositions that enable the experimental determination as to whether any gene in the genome of a diploid pathogenic organism is essential, and whether it is required for virulence or pathogenicity. The methods involve the construction of genetic mutants in which one allele of a specific gene is inactivated while the other allele of the gene is placed under conditional expression. The identification of essential genes and those genes critical to the development of virulent infections, provides a basis for the development of screens for new drugs against such pathogenic organisms. The present invention further provides Candida albicans genes that are demonstrated to be essential and are potential targets for drug screening. The nucleotide sequence of the target genes can be used for various drug discovery purposes, such as expression of the recombinant protein, hybridization assay and construction of nucleic acid arrays. The uses of proteins encoded by the essential genes, and genetically engineered cells comprising modified alleles of essential genes in various screening methods are also encompassed by the invention.

The invention discloses a mustard essential oil fresh preserver and an application thereof in refreshing fruits and vegetables. The main active component of the mustard essential oil fresh preserver is mustard essential oil containing over 99% of allylisothiocyanate, and the mustard essential oil fresh preserver is mainly applied to a solid sustained release tablet and packaging bags made of plastic aluminum film paper. The solid sustained release tablet consists of 5%-10% of the mustard essential oil, 80%-85% of beta- cyclodextrin and 5%-10% of stearic acid. The preparation method comprises the following steps of: firstly, fully mixing and stirring the mustard essential oil and the alpha (beta)-cyclodextrin according to the proportion in a seal container, adding the stearic acid, mixing and stirring, directly packaging in the paper bags, sealing the opening in time, filling in the plastic bags, sealing by vacuumizing, or after using a tablet machine to make tablets, filling in the plastic film bags and sealing the opening, finally storing at dark places. The fresh preserver can slowly release the mustard essential oil, can be used combining with fruit and vegetable plastic film package, and is suitable for storing, conveying and refreshing various fruits and vegetables of apples, pears, grapes, jujubes, oranges, mangos, cherries, bananas, potatoes, onions, garlic and the like, thereby effectively restraining the growth of pathogenic organisms after picking up the fruits and the vegetables in the process of storing and refreshing and prolonging the refreshing time and the distance of the market circulation.
