was able to correlate a specific pathogen caused a specific disease. We use his postulates because‚ if followed‚ they provide accurate data. 2. In 1884‚ Hans Christian Gram described a method of staining bacterial cells while not staining surrounding animal tissues; however‚ he thought the staining method he developed was faulty because not all bacteria stained. In a letter to the editor of the journal in which Gram published his findings‚ write your response to Gram’s concern. 3. Compare

bacteria do not maintain the crystal violet dye used in the gram staining method because of their cell walls that are thin .most of the gram negative bacteria are usually harmful to the host. (Gram negative rod shape salmonella entrica) There are several tests and experiments that classified the genus of the unknown species‚ which known as gram staining method.

distinct edges. Part 4: Direct Staining: Slide One: There were two clusters that were fairly easy to recognize. All of the cells were cocci. Some of the cells were large while others were practically nonexistent. Slide Two: There were different layers of cells. The cells were rectangular in shape and varied in size. A nucleus was visible in each cell. Slide Three: This slide was a mixture of different shapes. Nothing was recognizable. Part 5: Indirect Staining: Chains of both cocci and

Lab 4 – The Cell Answer Key Procedure 4.3 Draw a picture of a single Elodea cell and label all visible structures. See the diagram in your lab manual. Without staining‚ the only structures that should have been clearly visible should have been the cell walls and the green chloroplasts. Is this cell prokaryotic or eukaryotic? ______Eukaryotic_______________________ What evidence do you have to support this claim? The presence of organelles (chloroplasts) and its large size.

Different liquids can to different things to your teeth‚ and the most frequent thing done to teeth is staining. The reason for this project is to test what different liquids stain the teeth the most‚ so that people can prevent their teeth standing by not drinking as much of certain liquids. The next most common type of tooth stain is from a persons

Del Mundo‚ Layah Basella rubra as a biological stain Experimental The alugbati extract turned out to be favorable stain for plant nuclei and organelles especially for Hydrilla verticillata and as substitute for crystal violet or safranin in Gram staining. The extract stained the bacteria red-orange and the plant nuclei‚ and the cytoplasm red and light pink‚ respectively. The study is limited to the ability of Basella rubra (alugbati) to be used as a biological stain 2011 Gel-O-Fury- Saavedra‚ Ralph

Corneal Ulcer (Introduction) The eye is one of the vital organs in a human being. As seen on figure 1‚ the eye is composed of many different parts and function. The cornea is a clear covering over the colored iris and the pupil of the eye. The function of cornea is to help focus light on the retina and protect the iris‚ lens‚ etc. so that the eye can see. The cornea is best to compare with a standard contact lens. Although‚ the function of a cornea is to protect from harmful microorganisms

become a Microbiologist. Microbiologists investigate the growth and characteristics of microscopic organisms such as bacteria‚ algae‚ or fungi. Medical microbiology is perhaps the most well-known because it deals with the roles that microbes have in human illness. Other types include veterinary microbiology‚ environmental microbiology‚ and food microbiology. All these deal with the way microbes or microorganisms affect animals‚ the environment‚ and the food supply. Parasites kill people every day and are
