Data Set Used
In this study, food samples were intentionally contaminated with Escherichia coli O157:H7, and then DNA was isolated by using four commercial kits. The isolated DNA samples were compared by using real-time PCR detection of the Shiga toxin genes. The four kits tested worked similarly.
OBJECTIVES To examine susceptibilities of Bacillus anthracis and related species to 24 antimicrobials using and concurrently comparing two methods. METHODS Twenty-four antimicrobials were tested against 95 isolates of the Bacillus cereus group including 18 B. anthracis, 42 B. cereus, 5 Bacillus mycoides, 5 Bacillus mycoides/pseudomycoides, 6 Bacillus… (More)
To prove linkage between an environmental sample and an anthrax case, there must be isolates obtained from both that can be compared. Although Bacillus anthracis is easily isolated from powder samples, isolating it from soil is difficult because of the high bacterial count in it. Formulations of PLET were prepared, inoculated with B. anthracis, B. cereus… (More)
In this report we describe a new family of N-thiolated beta-lactams that have antibacterial activity against methicillin-resistant Staphylococcus aureus (MRSA). The compounds show unprecedented structure-activity features and an unusual mode of action for a beta-lactam antibiotic.
In order to cause the disease anthrax, Bacillus anthracis requires two plasmids, pX01 and pX02, which carry toxin and capsule genes, respectively, that are used as genetic targets in the laboratory detection of the bacterium. Clinical, forensic, and environmental samples that test positive by PCR protocols established by the Centers for Disease Control and… (More)
Pulsed-field gel electrophoresis (PFGE) is currently the gold standard for methicillin-resistant Staphylococcus aureus (MRSA) typing but only one enzyme, SmaI, is currently used for restriction digest. We report the use of virtual digestion to identify enzymes for S. aureus PFGE. Two enzymes (EagI and SacII) were identified and successfully used to… (More)
The genus Salmonella is composed of more than 2,400 serotypes, many of which cause enteric diseases in humans and animals. Several Salmonella serotypes are multidrug resistant, and there is evidence of the clonal spread of these strains from animals to humans. Salmonella enterica serotype Newport is one of the serotypes that increasingly present a… (More)
Since mid-March 2014, the frequency with which cases of Middle East respiratory syndrome coronavirus (MERS-CoV) infection have been reported has increased, with the majority of recent cases reported from Saudi Arabia and United Arab Emirates (UAE). In addition, the frequency with which travel-associated MERS cases have been reported and the number of… (More)
AIMS To (i) compare the limits of detection of Bacillus anthracis spores in three soils (one Florida, one Texas, and one a commercial Garden product) by PCR using DNA extracted with five commercial extraction kits and (ii) examine if removing organic acids or adding an enrichment step utilizing a growth medium will improve the detection limits.
