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.

The present disclosure provides polypeptides and polypeptide-nucleic acid conjugates comprising portions of epitopes, and methods of using target molecule binding components, such as aptamers, to present template sequences, where the target molecule binding components bind to target molecules unique to specific cellular targets, for the purpose of templated assembly of the epitopes for recognition molecules.

The present disclosure provides anti-Salmonella antibodies or antibody fragments such as camelid single domain antibodies (VHHs), along with associated nucleic acids, host cells and phages. Methods of reducing the presence of Salmonella in an animal or an animal environment, methods and formulations for treating Salmonella infection, and methods of detecting Salmonella are also described.

The present disclosure relates to camel id antibodies that inhibit growth, and colonization of Salmonella serovars. The present disclosure also relates to a modified Lactobacillus as a delivery vehicle for controlling Salmonella in a host organism.

Described herein are methods and antibodies useful for reducing, eliminating, or preventing infection with a bacterial population in domestic animals or humans. Also described herein are antigens useful for targeting by heavy chain antibodies and V.sub.HH fragments for reducing a bacterial population in domestic animals or humans.

The present invention features compositions comprising an anti-amyloid antibody and methods of treating microbial infection and treating or preventing microbial biofilms using the composition.

Intact, bacterially-derived minicells can safely introduce therapeutically effective amounts of plasmid-free functional nucleic acid to target mammalian cells. To this end, functional nucleic acid can be packaged into intact minicells directly, without resort to expression constructs, the expression machinery of the host cell, harsh chemicals or electroporation.

Intact bacterially derived minicells containing functional nucleic acids or plasmids encoding functional nucleic acids can reduce, in targeted mammalian cells, drug resistance, apoptosis resistance, and neoplasticity, respectively. Methodology that employs minicells to deliver functional nucleic acids, targeting the transcripts of proteins that contribute to drug resistance or apoptosis resistance, inter alia, can be combined with chemotherapy to increase the effectiveness of the chemotherapy.
