Bacteria Essay

Many bacterias are present without us realizing it. Bacteria that are present and ready to reproduce can cause problems in our daily lives at any rate. Mascara users are at risk from contaminants that may exist within their mascara wands or tube of mascara. Without proper care, bacterias will grow within the walls of the tube and cause many issues to users in the long run due to reapplying the product on a daily basis. “That mascara wand can do more than just make your lashes longer; it can…

biochemical tests are a good way to identify unknown bacteria from a sample. It is basically a similar to a trial and error method, but rather than using trial and error a person would be using positive and negative results. Using biochemical tests will help a person identify certain characteristics of the unknown bacteria through a series of chemical tests. Of course more than one biochemical tests must be used in order to ascertain which specific bacteria that a person may have. 2. Biochemical…

of endodontic treatment is to eradicate bacteria from the root canal and prevent reinfection9 (the effectiveness of various Alexanda almyroudi) Endodontic treatment includes the cleansing of pulp tissue and bacteria from infected root canals. This is performed mechanically by files and supported by irrigation with antibacterial and tissue dissolving solutions Mechanical instrumentation reduces the bacteria population but effective elimination of the bacteria is achieved when mechanical…

Yersinia petis, which better known as the plague, is caused by a gram-negative and rod-shaped coccobacillus bacteria. (Gram-negative meaning the bacteria does not contain the crystal violet stain involved in the gram staining test or process). The bacterium is also considered to be partially anaerobic, meaning it can function with oxygen but can also switch to a fermentation without oxygen. Yersinia petis function and survive through the lives and cycle of rodents and fleas, because of this,…

for ten days. The antibiotics depleted the bacteria that kept Clostridium difficile under control, which caused her to get a debilitating infection. She first got diarrhea and then went into shock. Her intestines swelled up and she had to get surgery to give room to her swollen and blood-deprived organs. The bacterium that caused her infection was Clostridium difficile. The bacteria already lived in her colon, but it was kept under control by other bacteria in the colon. C. difficile gets…

Cystic Fibrosis About 75% of all children either carry the Cystic Fibrosis gene or are personally affected by the Cystic Fibrosis gene. Since Cystic Fibrosis is becoming more and more common in children, it is important to truly understand how this genetic disease affects the body and the lives of the people who suffer from it on a daily basis. The defective Cystic Fibrosis (CF) gene is inherited and affects a protein that regulates how much salt moves in and out of cells. The buildup of salt…

Research by Philip Tierno, Jr., Ph.D., microbiologist, immunologist, and author of The Secret Life of Germs, has conducted research which indicates that your carpet and rugs are a lot dirtier than you think. In fact, these areas have around 200,000 bacteria per square inch. Eew, that's about 4,000 times dirtier than your toilet. How long has it been since you’ve cleaned your oriental or other area rugs? Surprisingly, they’re often overlooked. Many people are diligent about cleaning their…

affect the growth of antibiotic resistant bacteria is the use of human antibiotics in our food (Harris, 2014). The livestock are treated with the antibiotics and once again the bacteria that are resistant survive, multiply, and are sometimes passed on to humans (About Antimicrobial, 2015). If the meat from the livestock is not cooked well enough or long enough the bacteria then transfers to the person that eats it (About Antimicrobial, 2015). The resistant bacteria can also be transferred to…

the microbes that destroy or slow down the growth of the bacteria, whereas antimicrobial agents are the synthetic substances which developed in the laboratory that mimic effects of antibiotics. Selective toxicity means the microbial agents that kill the microbes without killing the host cells. Antimicrobial is divided into two spectrum of antibiotics – 1 Narrow spectrum: - This antibiotic is active against a selected group of the bacteria and will cause less resistance (SRS. n.d) 2 Broad…

Instead of partitioning into separate colonies, like the bacteria in figure one, the bacterial in figure three have dispersed throughout the entire petri dish and created an indistinguishable flat lawn of bacteria. Figure 4, Figure # 4: LB/amp: + PGLO, exhibited growth much like the bacteria in figure one. The only difference I noticed was that there were about two third the amount of colonies, with respect to figure one…
