Bacillus cereus and related species. F A Drobniewski + Author Affiliations Bacillus cereus is a gram-positive aerobic or facultatively anaerobic spore-forming rod. It is a cause of food poisoning, which is frequently associated with the consumption of rice-based dishes. The organism produces an emetic or diarrheal syndrome induced by an emetic toxin and enterotoxin, respectively. Other toxins are produced during growth, including phospholipases, proteases, and hemolysins, one of which, cereolysin, is a thiol-activated hemolysin.

Bacterial Identification - General Principles Through the early part of the twentieth century, there appeared to be a general feeling that the same battery of observations and tests could be used to characterize and identify any kind of bacterium. But as different, "exotic" types of bacteria were discovered, it was found that they would tend not to grow in the standard test media nor even in the usual conditions of incubation. Obligate parasites and strict anaerobes were among the emerging groups of bacteria needing special methods for growth and characterization. By the 1930s, a standard descriptive chart was developed for uniformity in recording the characteristics of the "aerobic saprophytes" (which are equivalent to what we call the "commonly-found" or "easy-to-grow" chemoheterotrophs in our general courses today). Click here and here for both sides of the standard chart constructed in 1934. There is no medium (differential or otherwise) that can possibly support the growth of all of the different species of bacteria.

What follows in this section is just a brief summary of much material presented and discussed over 24 hours of intensive instruction and interaction, so it's not an easy read. Consider it rather a quick tour of the cc world - mainly as a guide for further thinking and an opening to the expanded materials on our web-sites - this,, and others - / We began with the basics of conventional and community money systems - that all we really need to know about money, we already know and we always did. We know what it does, what it is and where it's from. Therapy Fixes Color Blindness in Monkeys Monkeys once color-blind can now see the world in full color thanks to gene therapy. The results demonstrate the potential for such methods to eventually cure human vision disorders, from color blindness to possibly other conditions leading to full blindness. The primate patients, named Dalton and Sam, are two adult, male squirrel monkeys that were red-green color-blind since birth — a condition that similarly affects human males more than females. Five months after researchers injected human genes into the monkeys' eyes, the duo could see red as if they had always had this ability. Since human genes were used and the monkeys' eyes and brains are similar to ours, at least in terms of color vision, the researchers hope the same procedure could work in humans. "People who are color-blind feel that they are missing out," said study researcher Jay Neitz, a professor of ophthalmology at the University of Washington, Seattle.
