Purpose: The purpose of this paper is to report the perceived impact of various health concerns on the academic performance of health sciences graduate students. Design/methodology/approach: The American College Health Association's National College Health Assessment (ACHA-NCHA), a 58-item anonymous survey, was distributed to all graduate health…

The issue of antimicrobial resistance in food animal agriculture was addressed by conducting clinical trials to assess alternatives to antimicrobials in dairy calf-raising and developing outreach to three different audiences. Current research was integrated into Extension programs for calf-raisers, animal science and veterinary students, and food…

Oregon State Univ. has offered FST 102 "Maraschino Cherry" as a 1-credit orientation course since 1994. The maraschino cherry serves as a vehicle from which faculty give their disciplinary perspective, for example, the chemistry of the maraschino cherry, processing unit operations, microbiology and food safety, food law, sensory…

The ability to appreciate the inter-connectedness of complex biological relationships can be difficult for many students. Graphical knowledge in the form of concept maps and flow charts are learning tools which can assist students to recognise the inter-connectivity. This report focuses on a trial which incorporates these two related visual…

The microbial growth curve is widely studied within microbiology classes and bacteria are usually the microbial model used. Here, we describe a novel laboratory protocol involving flow cytometry to assess the growth dynamics of the unicellular microalgae "Isochrysis galbana." The algal model represents an appropriate alternative to…

The focus of this Research Experience for Undergraduates (REU) project was on RNA secondary structure prediction by using a lattice walk approach. The lattice walk approach is a combinatorial and computational biology method used to enumerate possible secondary structures and predict RNA secondary structure from RNA sequences. The method uses…

Steven Kurtz, a professor of visual studies at the State University of New York, has been working with various bacteria as part of his counterculture exhibit artworks for nearly 20 years. Four years ago, federal agents raided his home in a bioterrorism investigation. The federal agents had been called to the house by local police officers…

The protein complement pathway comprises an important part of the innate immunity. The use of serum to demonstrate complement-mediated destruction across a series of bacterial dilutions allows an instructor to introduce a number of important biological concepts such as bacterial growth, activation cascades, and adaptive versus innate immunity.

In a climate of increased concern for the environment and its protection, teachers in disciplines as diverse as biology, microbiology, environmental studies, and environmental engineering may be seeking teaching materials and laboratory exercises that will enable them to introduce these new concepts into their classrooms and laboratories. The…

Oncogenic human papillomavirus (HPV) causes 99.7% of all cervical cancers. HPV Types 16 and 18 are responsible for approximately 77% of cases, and peak prevalence occurs in females younger than 25 years of age. The recent implementation of HPV vaccination provides females with the opportunity to prevent infection. School nurses are advocates of…

Natural selection is the mechanism of evolution caused by the environmental selection of organisms most fit to reproduce, sometimes explained as "survival of the fittest." An example of evolution by natural selection is the development of bacteria that are resistant to antimicrobial agents as a result of exposure to these agents. Triclosan, which…

It is an extraordinary challenge to offer an undergraduate laboratory course in virology that teaches hands-on, relevant molecular biology techniques using nonpathogenic models of human virus detection. To our knowledge, there exists no inexpensive kits or reagent sets that are appropriate for demonstrating real-time PCR (RT-PCR) in an…

The author discusses the importance of incorporating research into undergraduate curricula. Pedagogical approaches include faculty-directed research projects, off-campus internships, and research-oriented courses (R-courses). Examples of R-courses are reviewed, and an introductory microbiology course that teaches first year students "how to do…

As part of a multidisciplinary course that is cross-listed between five departments, we developed an undergraduate student laboratory experiment for culturing, isolating, and purifying the biopolymer, poly(3-hydroxybutyrate), PHB. This biopolyester accumulates in the cytoplasm of bacterial cells under specific growth conditions, and it has…

This paper describes a simple, rapid and low-cost technique for growing bacteria (or other microbes) in an environmental gradient, in order to determine the tolerance of the microbial population to varying concentrations of sodium chloride ions, and suggests how the evolutionary response of a microbial population to the selection pressure of the…
