Infection with gonorrhea also increases the risk of becoming infected with HIV (human immunodeficiency virus, the virus that causes AIDS). In 2000, 358,995 cases of gonorrhea were reported to the U.S. Centers for Disease Control and Prevention (CDC). In the United States, approximately 75 percent of all reported cases of gonorrhea is found in younger persons aged 15 to 29 years. The highest rates of infection are usually found in 15- to 19-year old women and 20- to 24-year-old men. Health economists estimate that the annual cost of gonorrhea and its complications is close to $1.1 billion. The disease can spread into the uterus and Fallopian tubes, resulting in pelvic inflammatory disease (PID). PID affects more than 1 million women in the United States every year and can cause infertility in as many as 10 percent of infected women and tubal (ectopic) pregnancy. Colonies of Arthrobacter have a greenish metallic center on mineral salts pyridone broth incubated at 20°C. This genus is distinctive because of its unusual habit of 'snapping division' in which the outer cell wall ruptures at a joint (hence its name). Microbiologists refer to the type of cell division in which rods break into cocci as reversion. Under the microscope, these dividing cells appear as chevrons ('V' shapes). Other notable characteristics are that it can use pyridone as its sole carbon source, and that its cocci are resistant to desiccation and starvation. Corynebacterium diphtheriae is a pathogenic bacterium that causes diphtheria. Also called the Klebs-Löffler bacillus, because it was discovered in 1884 by German bacteriologists Edwin Klebs (1934-1912) and Friedrich Löffel (1852-1915).

Does a bacterium’s cell wall, shape, way of moving, and environment really matter? Yes! The more we know about bacteria, the more we are able to figure out how to make microbes work for us or stop dangerous ones from causing serious harm. And, for those of us who like to ponder more philosophical questions like the origins of the Earth, there may be some clues there as well. Slime molds were once considered fungi, but unlike fungi, they can move, and their cell membranes are made of different stuff. Slime molds are made up of individual cells that form an aggregate mass. In their visible, aggregate states, they look like blobs, gooey or foamy masses, spilled jelly, or even dog vomit. They may be bright orange, red, yellow, brown, black, blue, or white. These large masses act like giant amoebas, creeping slowly along and engulfing food particles along the way.
