The present invention provides a binding assay that employs an activatable dormant bacteriophage carrying a reporter gene to qualitatively or quantitatively detect the presence of a substance of interest in a sample. Also provided is a simple culture device that is designed for manufacture and use in areas of limited resources. The device is useful for cell culture in such environments with limited resources because cells grow in paper just as they do in a culture dish.

Provided herein are, inter alia, biosensors and electrochemical cells comprising electronically conductive polymers and viral particles; diagnostic kits; and methods of detecting compounds in samples.

A phage dispensing system comprises a user interface, a phage treatment computing system, a phage laboratory, and a phage dispensing apparatus, including a dispensing kiosk. The user interface allows a treating physician to request testing of a patient sample by the phage laboratory to identify a phage mixture treatment. The phage computing system arranges shipping of the sample and provision of the identified phage mixture treatment to a dispensing apparatus located near the patient. The dispensing apparatus has a stock of phage vials which are used to prepare and dispense doses of the identified phage mixture treatment.

Methods involve feeding livestock animals, such as young poultry or calves, a feed product comprising a bacteriophage composition. The bacteriophage composition is configured to preserve the feed product and may exhibit lytic activity specific to one or more species of pathogenic bacteria, such as Salmonella, Escherichia, Campylobacter and/or Clostridium, which may be contaminating the feed product. The bacteriophage composition can remain in an inactive form until ingested by the animals, for example by including a protective outer coating, which may be comprised of digestible fat.

The present invention is directed to isolated bacteriophages having specificity and lytic activity against strains of Shigella species, methods of using the bacteriophages, progeny and derivatives derived therefrom, to control the growth of Shigella species in various settings (e.g., food safety, sanitation, modulating microbiome, prebiotics, probiotics).

Provided herein are methods for preventing or treating diseases, said methods comprising (i) inhibiting entry of bacteriophages and/or component(s) thereof into microbiota, bodily fluid(s) or tissue(s) of the mammals and/or (ii) inactivating or modifying bacteriophages and/or component(s) thereof present in microbiota, bodily fluid(s) or tissues of the mammals and/or (iii) inactivating or modifying bacteriophages and/or component(s) thereof in one or more of food, drinking water, water for washing, water for air humidification, air, or habitat object of the mammals.

Provided is a novel bacteriophage CJ23 (KCCM11365P). In addition, the present invention relates to an antibacterial composition including the bacteriophage CJ23 (KCCM11365P) as an active ingredient. Further, provided is a method of preventing and/or treating infectious diseases by avian pathogenic Escherichia coli(APEC) in birds using the bacteriophage CJ23(KCCM11365P) or the antibacterial composition containing the bacteriophage CJ23(KCCM11365P) as an active ingredient.

Disclosed herein are devices, methods, and systems for rapid detection of microorganisms using a recombinant bacteriophage. The specificity of recombinant bacteriophages for binding microorganisms allows targeted and highly specific detection of a microorganism of interest.

The present invention relates to a bacteriophage composition comprising one or more (suitably two or more, or three) bacteriophages selected from Sa87, J-Sa36, Sa83, J-Sa37, or mutants thereof, use of the same for medical or non-medical applications, kits, bandage, and wound dressing comprising the same.

Disclosed herein are methods and systems for rapid detection of microorganisms in a sample. A genetically modified bacteriophage is also disclosed which comprises an indicator gene in the late gene region. The specificity of the bacteriophage, such as Salmonella-specific bacteriophage, allows detection of a specific microorganism, such as Salmonella spp. and an indicator signal may be amplified to optimize assay sensitivity.
