The difference observed in MICs against gram-positive and gram-negative bacteria could possibly due to their structural variation. Gram-negative bacteria have toxic outer membrane made of liposaccharides layer which makes them less susceptible to antibiotics and antibacterial agents than gram-positive bacteria (Guo‚ Ma‚ Guo‚ & Xu‚

Enterococcus faecalis is a gram positive‚ commensal bacterium inhabiting the gastrointestinal tracts of humans and other mammals [1].E. faecalis can cause life-threatening infections in humans. Moreover‚ the antibiotic resistance exhibited at high levels by E. faecalis contributes to its pathogenicity [2]. Several reports state that enterococcal species possess the property of causing a variety of diseases in humans [3‚ 4]. It is known from previous studies that Enterococcus faecalis can cause endocarditis

most ordinary and unique organisms in the global sum of all ecosystems that can be used to make the world a healthier place to sustain human life. In today’s society the overuse of antibiotics in the agriculture industry has caused very strong antibiotic resistant bacteria (Page and Gautier 2012). Because antibiotics are not doing a good job at containing these bacterias like they use to‚ scientist are now moving towards bacteriophages.

aureus‚ a sample is obtained from the infection site and sent to a microbiology laboratory for testing. If S. aureus is found‚ the organism should be further tested to determine which antibiotic would be effective for treatment. Doctors often diagnose MRSA by checking a tissue sample or nasal secretions for signs of drug-resistant bacteria. Current diagnostic procedures involve sending a sample to a lab where it is placed in a dish of nutrients

Do you think it is possible to overuse our ocean resources? It is possible to overuse our ocean resources. We can drill and use an excessive amount of oil from the bottom of the ocean. This resource is made up of dead fish and other creatures that sink to the ocean floor and as sediment builds up the dead animal remains decompose and heat up to form the oil and natural gas. This can take up to thousands of years to form and if humans use too much oil we will have to wait another thousand years to

Mass Extinctions What is the biological significance of mass extinctions? PART A You are living in the 23rd century. 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

sick on certain occasions. These colds are usually treated with a antibiotics and will go away in a short period of time. Some bacteria however will develop a resistance to these antibiotics and are known as super bugs. These super bugs kill millions of people every year and will continue to do so until we get on top of it. People in the medical industry need to prevent this bacterial infection so we don’t have to use antibiotics as much anymore (Spellberg). Super bugs have become a huge problem
