Clostridium difficile also known as C. diff Microbiology ITT-Tech College Clostridium difficile grows without oxygen and in normal temperature of 98.6 that is why the body makes a perfect host. C.difficile exists in two states-the vegetative (growth) state or the spore state. In the vegetative state the bacterium is able to use nutrients to grow and divide. When conditions become unfavorable‚ C.difficile is able to enter a dormant state and form a highly resistant spore. When conditions become

MRSA By definition methicillin-resistant staphylococcus aureus (MRSA) is a bacterial infection that is highly resistant to antibiotics. Staphylococcus aureus is a strain of bacteria that is normally found on the skin or in the nasal passage way of about one third of the population. MRSA is the staphylococcus aureus bacteria that do not respond to antibiotics. MRSA needs a portal of entry in order to be infectious. This portal can be a sore‚ cut‚ breathing tube‚ or catheter. MRSA can present itself

MRSA is the term is used to describe a number of strains of the bacteria‚ Staphylococcus aureus‚ that are resistant to a number of antibiotics‚ including methicillin‚ though you are probably still wondering what is Staphylococcus aureus? | Staphylococcus Aureus is a group of bacteria that live on the surface of people’s skin and inside the nose. It is normally harmless:

Staphylococcus Aureus Clinicals Lesson 1.1 Ms. Marino Chelsea Trussell October 8‚ 2013 Staphylococcus Aureus [staf-uh-luh-kok-uh-s]‚ commonly known as Staph is an infection that can damage the skin and tissue of the body by either an Abscess or Cellulitis. It is also known as the most important bacteria’s that cause disease in people. Staph was first found in the 1800’s in Aberdeen‚ United Kingdom‚ by the surgeon Sir Alexander Ogston. He found the bacteria in pus from a surgical Abscess

mitosis and meiosis. 2) Differentiate gram-positive and gram-negative bacteria. a) A gram positive bacteria remains colored with gram staining even after washing with alcohol or acetone‚ whereas gram negative bacteria does not retain the stain when washed with alcohol or acetone. A gram positive bacteria outer membrane is absent and gram negative bacteria outer membrane is present. A gram positive bacteria’s peptidoglycan layer is 20-80 nm thick‚ whereas a gram negative bacteria’s cell peptidoglycan

plates were moved to a 4℃ environment to be stored until they were Gram stained using the process outlined in Friedman’s lab handout (Friedman 2017). Liquid cultures were made (from the streak plates stored) every seven days on the day before Gram staining. Observations of the milk samples‚ including pH‚ odor‚ and color‚ were recorded daily. The liquid cultures and plates were Gram stained every seven days. Observations of the Gram stained samples made under the microscope were

helped saved the lives of millions. Antibiotics are powerful medicines that fight bacterial infections. Used properly‚ antibiotics save lives. However as antibiotic resistance increases‚ the rise of super bugs such as Methicillin Resistant Staphylococcus aureus becomes more apparent. That is why it is important to carefully follow the instructions given to you when prescribed antibiotics. The feature of this article will be antibiotics as well as Antibiotic resistance.

Antibacterial action of the irrigants against Enterococcus faecalis in the root canal The overall percentage reduction of E. faecalis inside the root canal after biomechanical procedures was presented in table1. All the irrigants significantly reduced bacteria in comparison with positive control group (P< 0.01). The average reduction of bacteria in the presence of E.galbie did not have any significant difference with 2.5% NaOCl‚ CHX 2%‚ CHX 0.2% and M.communis L. (P > 0.05). The average reduction

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
