Under a high magnification of 15549x, this colorized scanning electron micrograph (SEM) depicted some of the ultrastructural details seen in the cell wall configuration of a number of Gram-positive Mycobacterium tuberculosis bacteria. As an obligate aerobic organism M. tuberculosis can only surv... Read More
New research suggests that people who are exposed to low levels of sunlight coupled with a history of having a common virus known as mononucleosis may be at greater odds of developing multiple sclerosis (MS) than those without the virus. The research is published in the April 19, 2011, print iss... Read More
Researchers have found that a strain of tuberculosis (TB) responsible for devastating some isolated Aboriginal populations in Canada was first introduced to these communities by French Canadian fur traders between 1710 and 1870. Read More
A potential vaccine against bacteria that cause serious gastric disorders including stomach cancer may be a step closer following a pioneering study by a University of Guelph chemist.
In the first published study of its kind, a team led by Prof. Mario Monteiro, Department of Chemistry, found... Read More
Advances in sequencing technology have inundated scientists with genomics data but left them with a drought of corresponding phenotypes. To address this problem, first author Robert Nichols of the University of California, San Francisco, and his colleagues built a database of E. coli phenotypes ... Read More

B. anthracis Colony Characteristics: A. Consistency sticky (tenacious). When teased with loop, colony will stand up like beaten egg white.
During the last 4 billion years, ancient enzymes have adapted from a much hotter, more acidic environment to the cooler global one that exists today.
The enzymes, known as thioredoxin were chemically stable at temperatures up to 32 degrees Celsius (58 degrees Fahrenheit) higher than their moder... Read More
For the first time, scientists have made star-shaped, biodegradable polymers that can self-assemble into hollow, nanofiber spheres, and when the spheres are injected with cells into wounds, these spheres biodegrade, but the cells live on to form new tissue.
Developing this nanofiber sphere as... Read More
Formate, the salt of formic acid, is an important product of metabolism in bacteria and in contrast to human metabolism a preliminary stage of the gas carbon dioxide, which is released in the combustion of sugar. Enterobacteriaceae, a large family of bacteria including the intestinal bacterium E... Read More
