Abstract: In one aspect, the disclosure relates to compositions and methods for dispersing exiting Salmonella biofilms and inhibiting formation of Salmonella biofilms. In various aspects, the disclosed compositions can be used in methods of treating a persistent Salmonella infection, including an asymptomatic infection. Such infections can colonize a variety of tissues, including the gall-bladder. Also disclosed are methods of treating typhoid fever. Also disclosed are methods for mitigating or preventing secondary outbreaks of typhoid fever by treating asymptomatic subjects who had been symptomatic for typhoid fever at a previous time. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

Abstract: A freestanding micrometer and method for determining the diameter of a cylindrical body, including measuring variations in diameter along a longitudinal length thereof, such as a roll used in the production of metal and paper sheet products. The micrometer comprises a housing supported on a circumferential surface of the cylindrical body. A first sensing element is movably supported by the housing and adapted for sensing a first surface point of the cylindrical body laterally spaced apart from the housing and disposed in a cross-sectional plane of the cylindrical body. A second sensing element is mounted to the housing for contact with a second surface point of the cylindrical body disposed in the cross-sectional plane of the cylindrical body. The first and second surface points locate, respectively, a terminal and midpoint of a chord lying in the cross-section plane of the cylindrical body, from which the diameter of the cylindrical body is determined.
