Scars form on the skin as part of the natural healing process of wounds in which the dermis is damaged. The dermis is the deeper layer of skin. When there are wounds on the surface layer or epidermis‚ scars usually do not form. There are two main types of scars‚ including hypertrophic or keloid scars that form because of an over production of collagen and atrophic scars that develop because of a loss of tissue. Acne scars are most often atrophic. When a pore in your skin becomes clogged with oil

A case report from May 24‚ 2001 involves a 62-year-old passenger who traveled by air on May 20‚ for a flight of greater than 8 hours in length. This passenger traveled from Sidney‚ Australia through Los Angeles International airport to JFK International Airport. This passenger began to feel ill and required assistance at the JKF airport. This passenger was hospitalized and diagnosed with meningococcal meningitis. From 1999 through 2001 the CDC received 21 reports of air-travel associated meningococcal

Common Causes of Infection Transmission What is Infection? Microbes can lead to an infection only if they have capacity to multiple. Our bodies get infections from pathogenic microorganisms that cannot observe by naked eye such as • Bacteria. These one-cell organisms are accountable for diseases‚ such as urinary tract infections. • Viruses. Is an acellular agent smaller than bacteria consisting mainly of genetic material‚ that can be active in a close environments ranging from the common cold

Microbiology in odontogenic infections Most odontogenic infections contain mixed aerobic and anaerobic bacteria. predominant bacterial species present in oral cavity are maunly Streptococcus ‚ Peptostreptococcus‚ Veillonella‚ Lactobacillus‚ and Actinomyces . 11‚12 The mixed aerobic-anaerobic composition of the bacteria involved in suppurative odontogenic infections is thought to be important in the pathogenesis of infection. if bacteria involved in mixed odontogenic infections are isolated in pure

To know the risk of adverse effects (AEs) in patients with Rheumatoid arthritis treated with tocilizumab‚ an IL-6 receptor antibody which is made by randomized controlled trials (RCTs). Method: A systematic literature search was conducted using the Cochrane library‚ PUBMED and EMBASE for all Randomized Control Trials (of the use of tocilizumab for Rhumatoid Arthritis treatment). Fixed effect meta-analyses were conducted to give the incidence of Adverse effects after treatment with and 8 mg/kg tocilizumab

Effects of Antiseptics and Disinfectants Purpose: The purpose of this lab is to discover substances that can slow the growth of‚ or kill‚ microorganisms. Hypothesis: The antiseptic that will prevent the growth of bacteria the most is iodine. The disinfectant that will prevent the growth of bacteria the most is bleach. Procedure: To begin the lab‚ turn the agar plate over and divide the plate into four quadrants and label the agar plate whether you

Listeriosis Although there are countless types of infectious diseases around the world‚ a great majority of them are preventable. Infectious diseases are disorders caused by organisms such as bacteria‚ viruses‚ fungi or parasites (Mayo Clinic‚ 2016). Listeria is not a commonly mentioned disease‚ however it has the potential to be deadly when not identified or serious symptoms are overlooked. This foodborne‚ infectious disease is caused by a gram stain-positive motile bacterium named Listeria

As Lyme disease progresses‚ it affects different body areas in varying degrees. The bacteria enter the body from the area where tick has bitten on the skin. As the bacteria spread in the skin‚ the infection causes an expanding rash that comes with "flu-like" symptoms. Later‚ it results in problems like joint pain‚ heart problems‚ and weak nervous system. Lyme Disease Diagnosis And Testing If done properly and performed with validated methods‚ then laboratory blood tests can prove to be quite

Gold is widely used in modern day medicine to treat disorders. This is because gold is very resistant to bacteria. Bacteria are microscopic single-celled organisms. Bacteria are prokaryotes‚ meaning the entire organism consists of a single cell with a simple internal structure. The DNA of a prokaryote is neatly packed in the nucleus. The bacterial DNA floats freely in a twisted threadlike mass called the nucleoid. Gold is unaffected by almost everything. The only materials that can affect gold are

In the experiment involving varying pH levels‚ E. faecalis‚ S. epidermidis‚ L. lactis‚ and L. casei were subjected to different pH levels and then were allowed to incubate in order to determine the minimum‚ maximum‚ and optimum pH levels for growth of specific bacterial species. It was found that lower pH levels between 2 and 4 inhibited or promoted little to no growth for E. faecalis‚ S. epidermidis‚ and L. casei. It is evident that these bacteria were resistant to alkaline environments‚ however
