Molly M. Leeper Trends in Toxin Profiles of Human Shiga Toxin-Producing Escherchia coli (STEC) O157 Strains, United States, 1996-2008 (Under the direction of Dr. Karen Gieseker, faculty member) Shiga toxin-producing E. coli (STEC) cause diarrhea, hemorrhagic colitis, and hemolytic uremic syndrome (HUS). All STEC produce one or both of two Shiga toxins, Stx1 and Stx2. STEC strains that produce S...

urinary tract infection (uti) is a neonatal life threatening infection which is usually treated with ampicillin plus an aminoglycoside or a third-generation cephalosporin. recently, growing number of escherchia coli species resistant to ampicillin and aminoglycosides have raised concerns regarding the necessity to change the empirical therapy. this motivates us to determine neonatal uti clinica...

background: the current study aimed to determine the effect and properties of surface-modified copper doped cu:zno nps on killing curves of bacterial pathogens. m ethods:   preparation  of   in  situ   surface-modified  copper  doped  zno nanoparticles (cu:zno nps) was done according to standard procedure.assay for antimicrobial activity of cu:zno nps against bacterial pathogens was carried out...

A Water Exclosure Treatment System (WETS) is developed and installed to minimize the occurrence of beach closures due to algae and Escherchia coli (E. coli) in an inland lake. WETS consists of an "exclosure" sub-system with a five-sided polypropylene, barrier that excludes offshore lake contaminated water from the swimming area. Inside the exclosure, water is pumped to a portable filtration-ult...

Novel therapeutic agents discovery have become crucial because humankind is experiencing issues regarding health and the environment. The present study focusing on thrombolytic agents, which are therapeutics for cardiovascular diseases, eco-friendly, safe can be used in comparison to synthetic that associated with some side effects their production not environment friendly. main objective of re...

Antibacterial properties and chemical characterization of the essential oils from summer savory (Satureja hortensis) extracted by microwave-assisted hydrodistillation (MAHD) were compared with those of the essential oils extracted using the traditional hydrodistillation (HD) method. While MAHD at 660 W required half as much time as HD needed, similar antibacterial efficacies were found from the...
