Antibiotic Sensitivity Patterns Of Hospital-Acquired And Community-Acquired Methicillin Resistant Staphylococcus Aureus, Iyad Kaddora
Antibiotic Sensitivity Patterns Of Hospital-Acquired And Community-Acquired Methicillin Resistant Staphylococcus Aureus, Iyad Kaddora
Theses, Dissertations and Capstones
Staphylococcus aureus is one of the most dangerous human pathogens. An intensive effort to control resistant staphylococci, especially methicillin resistant Staphylococcus aureus (MRSA), is vital as it is the most common cause of hospitalacquired infections. During the one year study period, a total of 35 MRSA isolates were collected. Fifteen isolates were identified as hospital-acquired (HA) infections, and 20 isolates were determined to be community acquired (CA). All 15 (100%) HA-MRSA strains were resistant to clindamycin and to erythromycin. Thirteen isolates (87%) were resistant to ciprofloxacin and levofloxacin, and 12 (80%) were resistant to moxifloxacin. Of the 20 CA-MRSA isolates, …
Investigation Of Environmental Microorganisms Associated With The Intrinsic Microbial Contamination Of An Alcohol-Free Mouthwash, Michelle D. Trickett
Investigation Of Environmental Microorganisms Associated With The Intrinsic Microbial Contamination Of An Alcohol-Free Mouthwash, Michelle D. Trickett
Theses, Dissertations and Capstones
The United States Pharmacopoeia (USP) Microbial Limits Test and Preservative Effectiveness Test were validated and completed on an alcohol-free mouthwash using standard USP recommended microorganisms and selected organisms isolated from the manufacturing environment. The microbial limits test using environmental isolates was found equivalent to the USP Microbial Limits Test currently used for release of the product. The preservative effectiveness test was performed to determine the efficacy of the parabens system against environmental isolates compared to those recommended in the USP test. In both tests Pseudomonas aeruginosa isolates exhibited resistance to the preservative system. All other isolates failed to grow after …
Antibiotic Resistant And Coliform Bacteria In The Ohio River; 2002 To 2004, Lisa Marie Smith
Antibiotic Resistant And Coliform Bacteria In The Ohio River; 2002 To 2004, Lisa Marie Smith
Theses, Dissertations and Capstones
During 2002 and 2003 samples, collected every five miles along the Ohio River, were analyzed for total cultivable bacteria, ciprofloxacin resistant bacteria, erythromycin resistant bacteria, tetracycline resistant bacteria, and fecal coliforms. During 2004 samples were analyzed for total cultivable bacteria, ciprofloxacin resistant bacteria, sulfamethizole resistant bacteria, tetracycline resistant bacteria, Virginiamycin resistant bacteria, total coliforms, and Escherichia coli. The objectives of this study were to systematically collect data on fecal coliforms, E. coli, and antibiotic resistant bacteria in the Ohio River and its major tributaries; to determine if antibiotic resistance populations are correlated to each other or to coliforms; and …
