Clostridium Difficile Clostridium difficile also known as C-diff in the medical world or C. difficile in the science world is a bacterium that infects the colon of humans. C-diff belongs to the bacteria Domain. Bacteria are unicellular organisms that contain Peptidoglycan in their cell walls. C-diff is a member of the phylum Firmicutes which means it has a Gram-positive stain and a low guanine and cytosine content. C-diff is also classified as a clostridia meaning it has a lack of aerobic respiration

graph must be constructed for each different environment‚ and the generation time of the bacteria in each environment must be calculated. The optimal environment for V. natriegens was found to be the BHI with 250 mM of NaCl. Introduction: The type environment that bacteria live in is essential to their growth. In order to establish what environment for V. natriegens is optimal‚ the generation time of the bacteria under several different environments‚ must be obtained. The type of system used for this

This study intends to examine: The bacteria population of samples obtained from several site across south east coast of England. Identify species of Gram Negative (-) & (+) of each sample. identify any faecal coliform bacteria which might suggest water contamination. These indicator organisms are used for indication of water contaminant by human and other warm-blooded animals

Most of their food drifts down from the surface‚ such as the dead algae that eventually sink.” This article was important to me because it saying that there are a number of bacteria found in the call home that biologists are still studying today. They predict that there might have living organisms on mars or on one of Jupiter’s moon. They stated that if there is it won’t walk on two legs or be able to talk. Living long beneath

Materials: 1-Tube containing unknown bacteria‚ crystal violet‚ iodine‚ decolorizing agent‚ Safranin‚ Bunsen burner‚ sheep blood agar plate‚ TSA plate‚ and bacitracin antibiotic disks. Procedures 1: 1.) Obtain a tube with an unknown bacteria and materials necessary to prepare a gram-stain. 2.) First place 5-8 loops of the bacteria onto the slide in a circular area and heat fix the bacteria to the slide. 3.) Place 3-5 drops‚ or enough to cover the bacteria‚ of crystal violet stain onto

Antibiotics are medications that either kill bacteria or prevent them from spreading. They work only against bacteria‚ not the viruses that cause the majority of sore throats‚ colds‚ sinus infections‚ and bronchitis. Most of the infectious diseases are caused by bacteria. Antibiotics transformed medicine. There are two segments of antibiotics‚ early history and modern history. Antibiotics can be defined as a medicine (such as penicillin or its derivatives) that inhibits the growth of

diseases are caused by agents such as bacteria‚ parasites‚ protozoa‚ fungus and virus. Bacteria exist on every surface including in the air and below sea level. Most bacteria are harmless but others are harmful to our body and can do bad to your health and internal organs‚ kidneys and the heart. Bacteria can invade into the body via the mouth‚ sexual organs‚ nose‚ eyes or any cuts which need to be cleaned and dressed. Bacteria can enter the body if food is full of bacteria or it isn’t cooked properly‚ this
