Clostridium tetani is a bacteria which can be found in soil and faeces‚ and causes the disease Tetanus. [Human Illnesses]. Clostridium tetani bacteria reproduce by binary fission because they are a bacteria. [St Margaret’s College]. In binary fission‚ bacteria reproduce by splitting themselves in half on a regular basis. [St Margaret’s College]. In ideal conditions‚ the Clostridium tetani bacteria may reproduce by binary fission every 20 minutes. [St Margaret’s College]. To live and reproduce by

Since bacteria is evolving rapidly and resisting antibiotics due to the overuse of the medicine‚ reducing the need and use would help slow down the bacteria from evolving. There are many things that can be done to help slow down the resistance of antibiotics. If the trend of this resistance keeps growing antibiotics wont be

One significant difference is that prokaryotes are without a cell nucleus and eukaryotes are cells with a membrane bound nucleus Prokaryotic falls in two taxa characteristic of organism: domain archaea and domain bacteria; however prokaryotic itself is not a taxon. Prokaryotes does not have a membrane surrounding its genetic material (DNA) they make proteins simultaneously to read their genetic code. Eukaryotes have a membrane called a nuclear envelope surrounding

slow down the growth of bacteria. The Greek word anti means "against"‚ and the Greek word bios means "life" (bacteria are life forms). Antibiotics are used to treat infections caused by bacteria. Bacteria are microscopic organisms‚ some of which may cause illness. The word bacteria is the plural of bacterium. How do antibiotics work? Although there are a number of different types of antibiotic they all work in one of two ways: • A bactericidal antibiotic kills the bacteria. Penicillin is a bactericidal

Introduction The experiment conducted was based upon the known attributes of two different groups of bacteria‚ those that are gram positive‚ and those that are gram negative. Using a specific staining procedure‚ it is possible to differentiate the two types under a microscope The gram stain method of differentiation is possible because of differences in the cell membrane between the two categories of bacteria. Gram positive cells have an extra thick layer that is made of highly-crosslinked peptidoglycans

utilized for bacterial growth are referred to as nutrients. Many bacteria can be identified in the environment by inspection or using genetic techniques. The nutritional requirements of a bacterium such as E Coli are revealed by the cell’s elemental composition. These elements are found in the form of water‚ inorganic ions‚ small molecules and macromolecules which serve either a structural or functional role in the cells. Bacteria thrive by four things oxygen‚ food (nutrients)‚ warmth and time

overgrowth of normal bacteria in the vagina. In the past‚ the condition was called Gardnerella vaginitis‚ after the bacteria that was believed to have caused the condition. However‚ the newer name‚ Bacterial Vaginosis‚ reflects the fact that there are a number of species of bacteria that naturally live in the vaginal area and may grow to exceed it’s natural balance. The Gardnerella organism was found not to be the sole culprit causing the symptoms. When these multiple species of bacteria become imbalanced

The widespread use of antibiotics has consequently caused a widespread evolution of bacteria and viruses. As a result‚ new antibiotics are required to fight the now stronger and more dangerous versions of the same illnesses that‚ at one point‚ could have been
