Antibiotics are rapidly becoming useless and we are forced to deal with the problems of the post antibiotic era. Our current state is urgent to say the least‚ the entire CDC urgent threat list is filled with a wide range of multi-resistant bacteria. Clostridium difficile is the first on the list‚ it is gram-positive and erupts from the distribution of normal colon bacteria. The on set primarily starts by taking antibiotics‚ because Clostridium difficile is immune to nearly all antibiotics. Second

NTRODUCTION Often in the study of microbiology‚ the need to identify an unknown microbe may arise. This aids in the recognition of which microbes are harmful or pathogenic as well as those that may be beneficial to us in some way. This report will detail how a similar project was performed in order to identify two unknown micobes using the techniques that were learnt during the course of the semester. We embarked on the project with the knowledge that we would have to identify a Gram(+) as well

Antibiotics in the Long Term Constantly improving our daily lives by making food safer so that we may live longer and healthier is one of the many things we have developed over hundreds of years of trial and error. Unfortunately there are few solutions that are 100% full proof and it is becoming apparent that the antibiotics that millions use on a daily basis might not be a sustainable solution. In the article “What If Antibiotics Stopped Working?” (Voss‚ 2014) the author begins the article with

The early twentieth century led to the discovery of penicillin‚ which revolutionized the use of curative agents to combat many bacterial contagions found around the globe. This was particularly useful in 1943 when the War Production Board outlined a plan to mass-produce a powdered formula of the drug to aid in the WWII American war effort.1 Penicillin’s use on Allied forces in the field reduced the number of amputations and deaths by an estimated 12-15%.2 Despite penicillin’s continued use today

A new study in Puget Sound‚ Washington has brought to light that when an orca breaks through the water surface and exchales‚ it sprays an array of bacteria and fungi. Consequently‚ these findings raise concern on whether infectious diseases could be a major stress factor for the struggling population of orcas. Moreover‚ the study took place throughout four years as scientists on boats followed orcas as they swam in Washington state waters and collected the droplets spreyed out as the orca exchaled

There are several genera of micro-organisms related to contact lens storage case contamination. Unlike CL contamination which is bacterial in nature‚ storage case contamination is often polymicrobial.(Larkin et al. 1990; Gray et al. 1995) Gray et al found that bacterial contamination is common in 77% of lens cases‚ followed by contamination with fungi (24%) and then protozoan (20%). Most commonly found organisms include Pseudomonas aeruginosa‚ Staphylococcus spp‚ Acanthamoeba spp and Fusarium species

In taxonomy‚ Legionella pneumophila belongs to the Legionellaceae family. In addition‚ Legionella pneumophila belongs to the Legionellales order‚ the Gammaproteobacteria class‚ the Proteobacteria phylum‚ and finally the bacteria domain.1 Legionella pneumophila is a Gram-negative‚ rod shaped‚ nonsporing‚ aerobic‚ facultative bacillus bacterium that is naturally found in fresh water sources that have high algal and iron contents. Legionella pneumophila is mainly aquatic however; it has an aerobic metabolism
