Background: A rapid in-house TM4 mycobacteriophage-based assay, to identify multidrug resistance against various anti-tuberculosis drugs, using the fast-growing Mycobacterium smegmatis mc2 155 in a microtiter plate format was evaluated, based on phage viability assays. Methods: A variety of parameters were optimized before the study including the minimum incubation time for the drugs, phage and M. smegmatis mc2 155 to be in contact. An increase in phage numbers over 2 h was indicative that M. smegmatis mc2 155 is resistant to the drugs under investigation, however when phage numbers remained static, M. smegmatis mc2 155 found to …

Periodontal disease, also known as periodontitis, is a dental disease that is estimated to affect 2.4 billion people worldwide. This disease is characterized by chronic inflammation and bleeding of gums, as well as loss of tooth bone density. Currently, treatments for the disease include dental surgeries and various types of antibiotics, but few are targeted specifically at the Red Complex bacteria which are strongly associated with chronic periodontitis. The Red Complex consists of three bacteria: Tannerella forsythia, Porphyromonas gingivalis and Treponema denticola. Each of these bacteria, are anaerobic oral pathogens that reside in the subgingival pocket adjacent to …
Total Salivary Protein Concentration And Its Correlation To Dental Caries, Emyli Peralta
Total Salivary Protein Concentration And Its Correlation To Dental Caries, Emyli Peralta
Honors Undergraduate Theses
Introduction: According to the World Health Organization, dental cavities are the number one chronic disease in children. Saliva coats the teeth all day and can serve many functions to maintain and protect teeth. Saliva has many proteins that can be both detrimental and essential to the preservation of tooth enamel. The purpose of this study is to determine if a correlation exists between the total protein concentration in saliva and the prevalence of cavities in the mouth. We hypothesized that there would be a positive correlation with total salivary protein concentration and the prevalence of cavities in the participant. Methods: …
