A bioterrorism attack is the deliberate release of viruses, bacteria, or other germs agents used to cause illness or death in people, animals, or plants. These agents are typically […]

For a while scientists were intrigued and puzzled about bacterial behaviors in particular their ability to move towards the food. Studies were conducted on the Escherichia coli bacteria. They discovered the presence of chemical sensors at both ends of the bacterium. This bacteria can be clearly seen under a microscope.

One of the major reasons why scientists and researchers study the biochemical and physiological processes of the bacteria is the rise of antibiotic resistant strains of bacteria pathogenic to man. Different avenues are searched in farther understanding the bacterial cells. But despite the new advances in drugs, harmful bacteria continue to be tough. And it […]

The scientists at the Rockefeller University have visualized the three-dimensional DNA structure damaged by bacterial toxin. The molecular image of the toxin shows exactly how the toxin is put together at the molecular level and damages human DNA. This toxin molecular image is shown in the May 27 issue of the journal Nature. According to […]

This article discusses the use of Ciprofloxacin as a prophylactic therapy for pregnant women exposed to an acute infectious disease caused by a spore forming harmful bacterium called Bacillus anthracis. It is generally acquired following contact with anthrax infected animals or anthrax contaminated animal products. Anthrax infection can occur in three forms, cutaneous […]
