The dirtiest thing you own maybe your cell phone. Imagine what touches your phone the most, probably your hands and face. Since cell phones are everywhere and have become one of the most helpful tools of our generation, they have their drawbacks. The use of cell phones happens everywhere today, one place being the hospital. From a study of phones and spreading of bacteria associated with health care associated infections, Karabay states, “Our study reveals that mobile phones may get contaminated by bacteria (such as Escherichia coli, Pseudomonas aeruginosa and Klebsiella pneumoniae), which cause hospital infections, and may serve as a vehicle for the spread of nosocomial pathogens” (Karabay, 2007). Touching contaminated

Poor hand hygiene - spread of germs from one patient to another or spread for hands to surfaces.

Pathogens are everywhere. They are in people, animals, and the environment. Pathogens come in a wide variety. The types are fungal, bacterial, viral, and other parasites. All pathogens can be dangerous, but two of them are more dangerous. These two types that more dangerous are fungal and bacterial. While both fungal and bacterial pathogens cause illness, they differ in the way they are transmitted, the way they are treated, and the diseases they cause.

There are many reasons for knowing the identity of microorganisms. The reasons range from knowing the causative agent of a disease in a patient, so as to know how it can be treated, to knowing the correct microorganism to be used for making certain foods or antibiotics. This study was done by applying all of the methods that I have been learned so far in the microbiology laboratory class for the identification of an unknown bacterium.

After many performed test such as the API 20E test strip, motility test, inoculated plates, gram stain, an identification flow chart which began with the results from an indole, MR, VP, and citrate test. This amongst many other test. These results brought the conclusion of my unknown culture to be Escherichia coli, my unknown number was 11.

The purpose of this laboratory exercise was to perform tests necessary to be able to distinguish one microorganism from 10 others. Using a series of biochemical tests and characteristics, unknown #22 was concluded to be Pseudomonas aeruginosa. A dichotomous key was mapped out and used during this process. Using this provided guidance as well as organization as to what the result may be.

There it was, an epidemic breakout. Something so powerful to the human body. How could this be so effective? Changing how our body is functioning; to making us severely sick. This is a disease we call Syphilis. Here we are in 1945 where it was seemed that Syphilis has made it’s breakthrough to humans carried from Christopher Columbus sailors’ from America to Western Europe, and soon enough around the world.

Syphilis is caused by the bacteria Treponema pallidum and it is highly contagious disease which spread primarily by sexual activity, including oral and anal sex. Although this disease is spread from sores, the vast majority of those sores go unrecognized. The infected person is often unaware of the disease and unknowingly passes it on to his or her sexual partner or pregnant women with the disease can spread it to the baby. This disease, called congenital syphilis, can cause abnormalities or even death to the child; therefore, a serologic test for syphilis should be performed on all pregnant women at the first prenatal visit (Anderson et al., 2013).

Isn’t making love is generally thought of as a magical thing shared between two people? Those two people are sharing a bond in which to express their affection towards each other. When making love, one doesn’t think of the chances harming themselves, however, in that enchanting exchange of adoration, there can be a horrific consequence if one fails to be cautious. It can result in sexually transmitted diseases. These diseases can kill any person who is sexually active. One needs to know that there is a possibility of receiving an STD. There are chances in which they can be cured but for some, it isn’t an option. An alternative may be to slow it down, but it will remain inside of you gradually weakening the immune system. It is all caused

Vibrio is a rod shaped bacteria that are also gram negative. They naturally appear in marine or estuarine environments. Also to note there are around about 12 species vibrio that have been known to cause diseases in humans which cause around about an estimated 80,000 illnesses, 500 hospitalizations and 100 deaths ever year in the US. The main reason that people get infected by vibrio is from coming into contact with seawater or through consuming raw or undercooked seafood. Vibriosis usually causes primary septicaemia (blood poisoning), diarrhoea, wound infections, or other extra intestinal infections. Vibrio parahaemolyticus is a strain of vibrio that has a rod shaped is usually found in saltwater and if ingested can causes gastrointestinal

2. Introduction: Each student was given unknown bacteria and was instructed to perform a variety of experimental tests that would help to identify their bacteria. During the process of identification, the unknown bacteria was added to many different testing medias using aseptic technique. They are as follows: lactose fermentation on eosin methylene blue (EMB), TSI (Triple Sugar Iron agar), Phenol red sucrose, the SIM test, H2S by SIM, IMViC (indole, motility, voges-proskauer, and citrate), Urease (urea broth), PDase (Phenylalanine Deaminase), Lysine Decarboxylase, and Ornithine Decarboxylase. Colonial morphology on EMB was used to

Introduction: Through the conduction of numerous experiments, the identity of two bacterial isolates was determined. The tested specimen was an unknown sample of a mixed culture of two different species of bacteria. The first step that was taken was obtaining a pure culture of each species of bacteria by isolating one species from the other. Once isolation was complete, the isolated cultures were tested using procedures that had been performed during previous lab sessions. A gram stain was performed on the two isolates. The isolate which had tested gram negative was then tested for the presence of cytochrome C and lactose fermentation. For the gram positive isolate, cell shape was determined and a catalase test was performed.
