referred to as the microbiome and accounts for nearly 2% of our total body weight. Trillions of bacteria and other microorganisms are thriving on our skin, genital areas, mouth, and especially intestines. (Ackerman, 2012) It is estimated that there are more than one thousand species that make up this community living in the digestive system alone. When we think of microbes in the body, we tend to think of bacteria that causes disease or germs that make us sick. Biologist, Sarkis K. Mazmanian believes we

Rinsing and gargling with salt water can clear bacteria as well as food particles and debris on which the bacteria feed on. Put one teaspoon of salt in lukewarm water and swirl the mixture until the salt dissolves completely. Gargling with this mixture will also help you keep a healthy mouth. 3. Brush with Baking Soda Baking soda contains hydrogen peroxide which neutralized the acid present in your mouth. Acids make for a favourable environment for bacteria growth in your mouth. Simply wet you toothbrush

chronic, recurrent and device-related infections; therefore treatment of biofilm infections has become an important focus in modern medicine. * Biofilms microcolonies of one or more species of bacteria or fungi typically growing adherent to a biotic or abiotic surface * It forms to allow bacteria to maintain themselves in a niche of their choosing rather than being washed away by the shear force of running water in the natural environment or the movement of body fluids and mucins in the body

BIO 1020 – Fall 2012 Laboratory 1: Bacteria and Protists pp. 1-29 You will be required to identify all of these organisms by kingdom and phylum/division (phylum = animal, division = plant). If a genus name (italics) is given on this handout, you will be responsible for that as well. You must know all of the structures and terminology listed below. Due to the ever-changing nature of biology, the nomenclature used in lab may differ from that used in lecture. A labeled drawing and short written

Transformation is the process of transferring genetic material between microbial cells (Tu 2008). Bacterial cells need to be in a state of competency prior to transformation (Isite 2013). Some bacteria naturally achieve this stage when nutrients and oxygen are low (Isite 2013). In the laboratory, bacteria were artificially induced with calcium chloride to be competent for transformation (Isite 2013). The bacterial cell membrane is permeable to chloride ions, but not to calcium ions (Isite 2013).

Even past mistakes teach no lesson to the FDA and to make things worse the capability of inspectors to recognize a bacteria during an inspection every 10 years is not prevent but pacification for bacteria to continue killing. After realizing that these deaths and

prokaryotic vs Eukaryotic Prokaryotes are generally known as bacteria. They are grouped into two domains Archea and bacteria. Prokaryotic cells are much smaller than eukaryotic ones and their organelles are not membrane bound. The ribosomes in prokaryotic cells are much smaller than in eukaryotic . The genetic material in prokaryotes is one single, ring-shaped chromosome with no nuclear membrane. Most prokaryotes have cell wall made mostly by peptidogylcans. Cell division is through binary

Staphylococcus comes from the Greek and the meaning of the word means a bunch of grapes. That’s what a staphylococcus bacteria looks like under a microscope. It could also be found under the nose and on the skin all over the body. The pathogen does not cause diseases but it could cause damage to the skin and the body. While having the grape like bumps on the skin then it could cause an infection because the bumps will start to leak out puss. Sometimes they will even cause the person to have boils

the growth and reproduction of bacteria. Bacteria reproduce by a process known as “binary fission.” Each cell of bacteria grows to its maximum size and then divides in the middle to form two new cells of bacteria. “The time required for this growth will take place amount to about 15 to 30 minutes. In only 8 hours, one bacteria cell can multiply to more than 3 billion cells in size, but more importantly, we aren't dealing with just one cell, there are many bacteria cells. Unclean hands alone can

of multi drug resistant strain shigella sonnei from its ancestor E. Coli and predecessor S. Flexneri and its spread to Vietnam Introduction Shigella is a genus of Gram-negative, facultative anaerobic, nonspore-forming, nonmotile, rod-shaped bacteria. The genus is named after Kiyoshi Shiga, who first discovered it in 1897. The causative agent of human shigellosis, Shigella causes disease in primates, and is the only naturally found in humans and apes. Shigella is one of the leading bacterial
