The present invention refers to peptides functionally related to Toll-like receptor 5 (TLR-5) ligand, having a sequence of amino acids ordered by means of the protein informational analysis techniques using the informational spectrum method with reference to the informational properties of flagellin. The sequence has in the informational spectrum the frequency of virtually the same value as the frequency characteristic determining the flagellin/TLR-5 interaction.

A composition for treatment of African Swine Fever in swine includes avian-sourced antibodies specific for an African Swine Fever Virus isolate. These antibodies are produced by avian animals immunized against the African Swine Fever Virus isolate and mixed with a protective/reactive matrix obtained from, isolated from, or derived from, non-hyperimmune colostrum.

Provided are novel methods for screening and testing for pathogens in food, water, and bodily fluids using methods that are faster to complete than conventional methods of culturing and plating that require lengthy times in properly equipped labs. The invention utilizes specific, rapid and sensitive optical detection to capture small concentrations of the target bacteria and render them amenable for detection with various specific synthesis binding agents approaches. The technique merges capture and detection steps with quantification unit suitable to provide results in a relatively shorter time current detection methods.
