Bacteria are unicellular microorganisms in each residence on Earth. Almost all have cell walls composed of peptidoglycan and reproduce by dividing (clone cells). Although many of these microbes are harmless or beneficial to humans and other pathogenic organisms that cause infectious diseases. A. The form of individual bacteria. 2. Are there bacteria in specific groups. 3. morphology of the colonies (the appearance of "colony", a group of millions of bacteria that have arisen from a single cell parents). ~ Sticks (pl. bacilli) = bacilliform

~ coca (coca Square sounds like COX-eye) = spherical

~ spiryly (pl. spirilla) = spiral

= ~ vibrios short, slightly curved bacillus, bacteria

sometimes occur in groups rather than individually, and form one cell affects the cell measures which they form, as bacterial cells share. Bacilli divided along one axis, and sometimes dealt with in pairs or chains. Since they only split along one axis, you will not find bacteria in clusters, such as formed by Staphylococcal bacteria. Koki divided into one or several planes, producing cells in

size, shape and arrangement of cells is often the first clues to identify the bacteria. However, since there are many "doubles" and other methods of microscopy, what should purchase strattera be used to determine the genus and species of organism. Bacterial populations are growing very rapidly when they are supplied with nutrients and environmental conditions, allowing them to flourish. With this growth, different types of bacteria sometimes produce colonies that are distinctive appearance. Some colonies may be painted, some round, others irregular. Characteristics of colony (shape, size, color, etc.) are called "morphology of the colonies." Colony morphology way scientists can identify bacteria. There are several basic characteristics of the morphology of the colonies, which are usually measured. A. Form - What is the basic form of the colony? For example, circular, filamentous, etc. 2. Height - What form of cross-section of the colony? To verify this, turn the Petri dish at the end. 3. Margin - What form of increased land of the colony? 4. Surface - What surface colonies appear? For example, smooth, shiny, rough, dull (as opposed to shiny), wrinkled (wrinkled), etc. 5. Opacity - Is the colony transparent (clear), are opaque, translucent (almost clear, but distorted vision looking through frosted glass), iridescent (changing color in reflected light), etc. 6. Hromohenez (pigmentation) - for example, white, buff, red, purple, etc. Bauman, R. (2005) Microbiology. Pearson Banjamin Cummings. Park Talaro, K. (2008) framework in the field of microbiology.
