Laboratory Exercises In Microbiology: Discovering The Unseen World Through Hands-On Investigation, Joan Petersen, Susan Mclaughlin

Open Educational Resources

The exercises in this laboratory manual are designed to engage students in hand-on activities that reinforce their understanding of the microbial world. Topics covered include: staining and microscopy, metabolic testing, physical and chemical control of microorganisms, and immunology. The target audience is primarily students preparing for a career in the health sciences, however many of the topics would be appropriate for a general microbiology course as well.

An Analysis Of Fecal Coliform Bacteria As A Water Quality Indicator, Janet Heyl Vail

Dissertations

The focus of this study is to assess the efficacy of fecal coliform bacteria as a microbiological water quality indicator. The scientific and educational context of fecal coliform bacteria is explored through analysis of large sets of water quality data, focused field monitoring projects, and review of commonly used resources for school-based and volunteer water-related studies. Analyzed data sets include long term sampling (10 years), multiple sites, daily samples, storm event samples, and other parameters monitored in parallel with bacteria. Special attention is given to data sets from Kent County, Michigan. A background reference site in Michigan unimpacted by humans …

The Role Of Ampk In Viral Infection, Theresa Moser

Publicly Accessible Penn Dissertations

Host factors are crucial in determining the outcome of viral infection. As obligate intracellular pathogens, viruses are highly dependent on numerous cellular proteins and processes, and also must evade multiple antiviral defense mechanisms. Since viral pathogens represent a significant threat both to human health and agriculture, a better understanding of these interactions could facilitate the treatment of viral infections and provide novel targets for therapeutics. In particular, Poxviruses include medically important human pathogens yet little is known about the specific cellular factors essential for their replication. To identify genes essential for vaccinia infection, I used high-throughput RNA interference to screen …

Identification Of Bacterial Species Using Colony Pcr, Kaiti Walker

Honors Theses

My research consisted of two separate parts, both involving the PCR methods. In part one I was trying to identify bacteria isolated from a chicken coop. In part two I was trying to identify bacteria isolated from the bluff. In both parts, I used a technique called colony PCR. This concept uses a single colony of bacteria to complete the PCR reaction. One pipet tip from a single colony is selected from the plate and mixed into a tube containing ultrapure water. A small amount of this bacterial mixture is then added into the PCR reaction. In the first part …

Microbiology: A Laboratory Experience, Holly Ahern

Milne Open Textbooks

As a group of organisms that are too small to see and best known for being agents of disease and death, microbes are not always appreciated for the numerous supportive and positive contributions they make to the living world. Designed to support a course in microbiology, Microbiology: A Laboratory Experience permits a glimpse into both the good and the bad in the microscopic world. The laboratory experiences are designed to engage and support student interest in microbiology as a topic, field of study, and career.

This text provides a series of laboratory exercises compatible with a one-semester undergraduate microbiology or …

A World Review Of Fungi, Yeasts, And Slime Molds In Caves, Karen J. Vanderwolf, David Malloch, Donald F. Mcalpine, Graham J. Forbes

International Journal of Speleology

We provide a review of fungi, yeasts, and slime molds that have been found in natural solution caves and mines worldwide. Such habitats provide frequent roost sites for bats, and in eastern North America the environmental conditions that support white-nose syndrome, a lethal fungal disease currently devastating bat populations. A list of 1029 species of fungi, slime moulds, and yeasts in 518 genera have been documented from caves and mines worldwide in 225 articles. Ascomycota dominate the cave environment. Most research has been conducted in temperate climates, especially in Europe. A mean of 17.9±24.4SD fungal species are reported per study. …

Contribution Of Probiotics Streptococcus Salivarius Strains K12 And M18 To Oral Health In Humans: A Review, Turner A. Stowik

Honors Scholar Theses

The overgrowth and disequilibrium of pathogenic microorganism species both native and non-native to the oral cavity can manifest into a variety of different oral diseases, pathologies, and afflictions in humans, including dental caries, gingivitis, pharyngitis, halitosis, and oral candidiasis. Two bacterial strains with clinically-significant probiotic applications in curtailing the pathogenic bacterial growth involved in these conditions are Streptococcus salivarius strain K12 and Streptococcus salivarius strain M18. To summarize the most up-to-date in vitro, in vivo, and clinical research findings, administration of these S. salivarius strains typically in the form of probiotic lozenges results in colonization, reduction in inflammatory measures, …

A Multidisciplinary Approach To Food Safety Evaluation: Hummus Spoilage And Microbial Analysis Of Kitchen Surfaces In Residential Child Care Institutions (Rcci) In Massachusetts, U.S.A., Elsina E. Hagan

Masters Theses 1911 - February 2014

Food borne illnesses continues to be a public health challenge in the United States (U.S.); an estimated 9.4 million incident cases occurred in 2011. In view of this challenge we conducted two food safety studies; 1) related to product formulation (hummus spoilage challenge study) and 2) evaluating the microbial safety of domestic kitchen surfaces in Residential Child Care Institutions (RCCI pilot study).

Hummus is of Mediterranean origin but is currently eaten globally. This challenge study evaluates a variety of industrial hummus formulations (four in total, differing in pH and/or addition of a preservative (natamycin). Two batches were setup: batch 1; …

An Analysis Of Bacterial Contamination Of Chicken Eggs And Antimicrobial Resistance, Holly Spitzer

All College Thesis Program, 2016-2019

Chicken eggs are a major component of American diets, with an average yearly consumption of approximately 250 eggs per person (American Humane Society). While highly nutritious, eggs are also one of the leading causes of food poisoning and food borne illness in the United States. Eggs may become contaminated by a number of different types of bacteria during production, including Salmonella, a group of bacteria that, according to the CDC, causes more than 1.2 million cases of food borne illness in the United States every year. In an effort to decrease the frequency of bacterial contamination, many food producers …
