The present invention relates to (1) an enzyme-linked immunosorbent assay (ELISA) for detection in milk of antibodies of any isotype which are specific for Staphylococcus aureus proteins in molecular weights ranging from 14,000 to 26,000 daltons, (2) a process for production and purification of the proteins, (3) a method of performing the ELISA utilizing the proteins (4) use of the ELISA for detection of intramammary infection by S. aureus, (5) preparation of monoclonal and polyclonal antibodies against the selected fractions, (6) use of such antibodies of purification of infection specfic antigens, and (7) use of the antibodies in an ELISA for antibodies produced in an individual in response to infection by S. aureus.

Diagnostic test for staphylococcal mastitis

The present invention relates to (1) an enzyme-linked immunosorbent assay (ELISA) for detection in milk of antibodies of any isotype which are specific for Staphylococcus aureus proteins in molecular weights ranging from 18,000 to 26,000 daltons, (2) a process for production and purification of said proteins, (3) a method of performing said ELISA utilizing said proteins and (4) use of said ELISA for detection of intramammary infection by S. aureus.

Diagnostic test for Staphylococcal mastitis in cattle

An apparatus and method is described which enables one to determine the amount of chamber pressure produced by a cartridge in any firearm chambered for said cartridge. A plastic material of uniform size, consistency, and shape is attached to the outside of the cartridge case with translucent adhesive tape - the total thickness of the plastic material and tape being such that chambering of the cartridge is not significantly inhibited. During firing the pressure inside the cartridge case causes the plastic material to spread between the cartridge case and the tape as both are forced against the rigid surface of the chamber wall. The width of the plastic material is measured and is proportional to the amount of pressure generated during firing of the cartridge. The actual pressure in pounds per square inch is determined from a standard curve that relates the width of the plastic material to pounds per square inch.
