Bacterial Morphology Demonica Britt Microbiology DL1 March 23‚ 2013 Abstract This lab was performed to identify and familiarize with a microscope while precisely observing various bacterial shapes and their arrangements in different types of specimens of bacteria. The microscope parts and capabilities were clearly identified and used successfully and the bacteria were clearly illustrated showing the bacterial shapes and arrangements with all the appropriate magnification being utilized.

Bacterial Smears Are Fixed before Staining to? Answer It is important to heat fix the bacterial smear before staining so as to‚ kill the bacteria‚ firmly adhere the smear on to the microscopic slide to prevent washing off during staining‚ and to allow the sample to readily take up the stain. Reference: www2.hendrix.edu What is the purpose of heat- fixing the smear? It helps the cells adhere to the slide so that they can be stained. The purpose of heat fixing is to kill the organisms without

· Taxonomy ○ Science of classification ○ Provides an orderly basis for the naming of organisms and for placing organisms into a category (taxon) ○ Makes use of and makes sense of the fundamental concepts of unity and diversity among living things ○ Basic principle is that members of higher-levels groups share fewer characteristics than those in lower-level groups * Escherichia coli - rod shape and have a Gram-negative cell wall * Even members of the same species display variations

culture. The unknown was identified using differential tests to determine its metabolic and morphology characteristics. Results from the differential tests indicated that unknown culture 5 is Staphylococcus aureus. Introduction: The purpose of this lab was to determine the identity of an unknown bacteria slant culture using a series of differential tests. The tests used to identify the unknown bacterial culture included: Gram stain‚ mannitol salt agar‚ coagulase tube test‚ and an antimicrobial

extreme environments. Bacteria is the more numerous type of prokaryotes. The group hypothesizes that the samples taken from different environments will all cultivate diverse morphology in fast growing rates in each environment. The aseptic technique was used to cultivate bacteria from different environments. The diversity of morphology and the growing rate of the bacteria was different in each environment. Introduction Prokaryotes are the oldest known life-forms‚ having existed for the last 3.5 billion

Microbiology Lab Quiz #2 Study Guide Exercise 9 -- The Gram Stain Compare and contrast simple and differential staining techniques. Simple Staining Simple staining is useful in determining the basic morphology of an organism. Simple staining involves only one reagent i.e. crystal violet‚ basic fuchsin‚ or methylene blue. Simple dyes used to stain bacteria have a positive charge cationic (+)‚ therefore‚ they are attracted to the bacteria that are usually negatively charged anionic (-) Depends

We traveled Cox’s Bazar two times on the year of 2008 and 2010.We went there by bus and stayed for a few days in the rest house of Bangladesh Power Development Board. We visited Teknaf‚ Saint Martin (it’s a rock beach)‚Himchori‚ Mohesh Khali Island‚ Enani beach‚ Dulahazra Safari Park etc. We went Chera Dip (Island) too by trawler from Saint Martin. It’s a coral beach. The corals can change their colors. There are lots of tiny blue fishes. The size of the chera dip is 1 to 1.5 square kilo metres.

coccoid forms. Bacterial morphology was determined by gram staining via light microscopy (Camera Digital DP 72-BX 51‚ Soft imaging system‚ Olympus‚ Japan). When coccoid forms of H. pylori isolates reached to more than 90%‚ bacteria went for other processing as well as evaluating their viability. The same approach was repeated for reference strain as control group with and without antibiotic. Coccoid form suspensions of H. pylori were centrifuged and washed by PBS. Then‚ bacterial sediments were stained
