Gram Characteristics of Bacteria Introduction Bacteria are interesting little critters in that they are not easily visualized without some sort of stain. In classical methodology‚ two different kinds of stains have been used to identify bacteria: acidic and basic dyes. Acidic dyes are so called because they consist of a salt that has a cation that transfers no color‚ but the anion portion is colored and does give off color. Basic dyes consist of an anion that does not give off any color and a cation

Microbiology report Gram stain Objectives: The aim of this experiment was to be able to stain bacteria correctly and be able to see it under the light microscope. In 1883 Hans Christian Gram discovered an important staining method that is used extensively today. The stain is called the Gram Stain. This experiment was done in order to differentiate microbes into two basic groups: Gram positive microbes and Gram negative microbes. The purpose of this experiment was to learn the gram staining method and to

MICROBIOLOGY SECTION The microbiology section aims at studying yu ailments and diseases from the isolation of suspected causative organisms. The processes involved in the isolation of these organisms include; culturing‚ staining‚ microscopy and sensitivity tests. Samples collected for examination include; stool‚ blood‚ sputum‚ urine‚ vaginal swab‚ wound swab and wound biopsy. Bacterial Culturing and sensitivity Cultures are carried out to isolate suspected organisms from a sample. There are different

contaminated dirt by running it through a series of identification techniques. Some of these techniques were simple staining‚ gram staining‚ and isolation techniques. The hypothesis of this experiment was that the bacterium is of the bacillus family due to the rod shape. Due to multiple complications with the PCR‚ a new hypothesis couldn’t be formulated. Methods: In this experiment‚ a 1 gram sample of contaminated dirt was taken and mixed with 100 mL of sterile water then shaken. After allowing the sediment
