Antimicrobial resistance (AMR) is a world-wide public health threat that projected to lead 10 million annual deaths globally by 2050. The AMR issue has led the development of action plans combat AMR, including improved antimicrobial stewardship, new antimicrobials, and advanced monitoring. National Resistance Monitoring System (NARMS) United States (U.S) Food Drug Administration along with U.S. Centers for Disease Control Department Agriculture monitored resistant bacteria in retail meats,...
Developing effective and sensitive detection methods for antimicrobial resistant Salmonella enterica from surface water is a goal of the National Antimicrobial Resistance Monitoring System (NARMS). There are no specified recovery S. in waters U.S. A multi-laboratory evaluation four - bulk enrichment (BW), vertical Modified Moore Swab (VMMS), modified Standard Method 9260.B2 (SM), dead-end ultrafiltration (DEUF) was undertaken to recover water. In Phase 1, one-liter volumes were collected...
Immunomagnetic separation used with culture based methods has been a useful technique in the detection of pathogens. However, previous studies have not answered many necessary questions for real world applications. The objective this study was to assess efficacy different immunomagnetic (IMS) bead types recovery correct serogroup from mixture big six non‐O157 Shiga toxin‐producing Escherichia coli strains. To determine impact matrices on recovery, samples sterile phosphate buffered saline...
In the field, foodborne pathogens such as enterohemorrhagic Escherichia coli (EHEC) are capable of surviving on produce over time, yet little is known about how these adapt to this environment. To assess impact pre-harvest environmental conditions EHEC survival, we quantified survival romaine lettuce under two relative humidity (75% and 45%) seasonal (March June). Greenhouse-grown was spray-inoculated with placed in a growth chamber, mimicking typical for June March Salinas Valley,...

Traditional short-gate pulse-Doppler devices rely on hardware gating to measure a blood vessel's velocity profile. In the same spirit as software radio, advanced digital signal processor (DSP) technologies suggest an alternative traditional methods. By way of computer simulation, this paper explores viability software-gated technique for measuring Simulations utilize particle model that is then mixed, filtered, and sampled. Spectral analysis provides profile information. Preliminary results...
