Coccus is a term used to describe a type of morphology that helps us distinguish different kinds of bacteria. The cell’s morphology is only one of the many ways we can differentiate the different species. Looking at these bacterium underneath the microscope is an important step to determine which kind of species it is. All cocci bacteria are not gram positive‚ but this lab will examine only this kind because of their influence in human health. Staphylococcus Aureus is a gram-positive coccus bacterium

resistant to the antibiotic vancomycin. Enterococci infections are the most common type acquired by hospitalised patients. Vancomycin was the last-line antibiotic for hospital treatment of serious methicillin-resistant staphylococcus aureus (MRSA) infections according to Collignon (2002‚ p. 327). These enterococci have become resistant because of the overuse of the antibiotics that control these infections. Cross-resistance between classes and exposure to one antibiotic may promote resistance to others

One of the most serious infections is called Methicillin-resistance Staphylococcus aureus (MRSA). Bacteria is most likely to enter the body through disrupted areas of skin‚ such as areas of recent surgery‚ IV catheters‚ cuts‚ puncture wounds‚ an ulcer or dermatitis. Certain types of

Ampicillin is a toxin that causes bacterial cells to lyse by hindering cell wall synthesis. The selectable marker is the Ampicillin Resistance gene that codes beta-lactamase enzyme which breaks down the antibiotic. The transformed E. coli cells will be able to thrive in an ampicillin environment. The purpose of this experiment is to see how

In contaminated environments‚ presence of metal resistant genes on plasmids often provide the other bacteria within the same niche to acquire the necessary genes at times of severe

It is a constant problem because of the misuse of antimicrobials in farms‚ disease treatment‚ growth promotion in domestic livestock‚ and the increasing problem of antimicrobial resistance. Current research is being conducted with bacteriophages because they have been identified as a prospective alternative bio-control method to control Salmonella contamination in a variety of foods.

All knowledge of scientific things have been hidden from the human race by evil dictators during the last 2 generations of humans. One brilliant scientist‚ Albert Einstein the 16th‚ has rebelled against the dictators. He has devised a time machine and is asking for volunteers to go back in time and bring back important scientific discoveries. Your assignment is to go back to

Gram negative bacteria resistant patterns are troublesome to the general public because common illnesses could suddenly become deadly. Carbapenem antibiotics are seen as a last resort. If gram-negative bacteria develop a resistance to this antibiotic‚ antibiotics could become useless in treating a super resistant strain of gram-negative bacteria. NMD-1 is one of the most resistant genes found in gram negative bacteria. If this genes is readily passed between different types of bacteria‚ widespread

Any species of bacteria can turn into a superbug. A superbug is a strain of bacteria that is resistant to antibiotics. According to webmd.com "Every year‚ about 2 million people get sick from a superbug‚ according to the CDC. About 23‚000 die. Earlier this year‚ an outbreak of CRE (carbapenem-resistant enterobacteriaceae) linked to contaminated medical tools sickened 11 people at two Los-Angeles area hospitals. Two people died‚ and more than 200 others may have been exposed." This has become a serious
