Rita Bernstein On November 14‚ 2012‚ Rita Bernstein visited Bergen Community College to talk about Escherichia Coli O157:H7. Escherichia coli or better known as E.coli is a tube-shaped bacterium that is found in the stomachs of warm-blooded animals. O157:H7 is a member of the E.coli family‚ which produces shiga toxin‚ and are capable of producing bloody diarrhea. E.coli O157:H7 attacks red blood cells‚ it interrupts flow of oxygen‚ and it breaks down walls of vessels. E.coli can

Microorganisms are classified according to their structure. By means of flow charts‚ diagrams and tables explain the differences between Viruses‚ Bacteria‚ Cyanobacteria‚ Achaea and Fungi. Bacteria or bacterium are unicellular microorganisms. They are essentially only a few micrometres long and form of various shapes including the spheres‚ rods and spirals.

but the first reported case/illness was on October 12th‚ 2001. The causative agent of anthrax is Bacillus Anthracis (American Anthrax). Although the anthrax issue was unknown to many before 2001‚ the bioterrorism opened everyone’s eyes about how deadly anthrax can be. Bacillus anthracis is the bacterium that causes anthrax and bacillus anthracis is also the scientific name used by scientists. Bacillus anthracis is the aerobic (needs air)‚ spore forming bacteria that grows well in the body‚ especially

This is a gram positive bacteria which is found in soil and/or water where it can lie dormant until contact with host. Portal of entry can be from a cut‚ inhaled‚ ingested or a biological vector.

in Egypt. A German physician and bacteriologist‚ Robert Koch traveled with a group of German colleagues from Berlin to Alexandria‚ Egypt in August‚ 1883. Following necropsies‚ they found a bacillus in the intestinal mucosa in persons who died of cholera‚ but not of other diseases. He reasoned that the bacillus was related to the cholera process‚ but was not sure if it was causal or consequential. He stipulated that the time sequence could only be resolved by isolating the organism‚ growing it in

humans through bites (Forsyth). As people migrated it reached Haiti and then spread to America (Clark p. 65). The bubonic plague‚ too‚ was a spontaneous epidemic. The Black Death occurred because a bacillus was carried by fleas that fed off the blood of humans and transmitted the deadly bacillus in the process (Packer). It began in China and spread by migration throughout all of Europe and even America (Forsyth). Efforts to contain both diseases were entirely unsuccessful. AIDS is now an international
