uncultured community sample. 16S rRNA genes will distinguish bacteria and represent the microbial diversity of the sampled elliptical. An estimate of the cleanliness of the elliptical will be made based on species-abundance as well as evidence of any pathogenic strains. We will also compare and contrast respective populations of bacteria on clean and disinfected ellipticals to assess disinfectant effectiveness. Methods We collected bacteria from the elliptical, purified and amplified the total community

we use Koch's postulates instead of Bassi's or Pasteur's postulates? Answer #1: Koch was the major mind in establishing that microorganisms cause a specific disease. He was able to prove that certain bacteria was present in the blood of the infected person or animal, but the presence of the bacteria could have been caused by the disease. Koch proved that certain infectious diseases are caused by certain microorganisms that can be isolated and cultures onto a media. The requirements Koch established

three agencies that overlook the making and distributing of genetically modified foods, giving us peace of mind that they are regulated and tested before being distributed. GMO’s have, most importantly, helped us in curing fruits and vegetables of viruses and bacterial infestations, as well as environmental changes that the food is not used to. Farmers have been modifying the pollination of their crops by spreading the pollen of one high yield plant on to another in hopes that the right genes

The importance of: • Hygienic food preparation - This is important in order to avoid illnesses and even death due to the viruses, bacteria and parasites found in the food, which may lead to food poisoning. • Good personal hygiene – Keeping a good hygiene helps to prevent the development and spread of infections, illnesses and bad odours. The most important way of reducing the spread

forth allowing the cell to move. Plasmid is found in bacteria. They need a host to live of. It is a clone of the bacteria’s DNA. It typically provided the bacteria with genetic advantages, such as antibiotic resistance. Plasmid can be passed to other cells through a process called conjugation. Plasmid can be cloned into daughter cells thousands of times, making it easy to spread the bacteria’s DNA. Plasmid is not said to be live just like a viruses. Plasmid is very important if come type of organism

Genetic Engineering - Genetic Engineering is the use of various methods to manipulate the DNA of cells to change hereditary traits or produce biological products. It is a manipulation of genes that allows scientists to put genes from one organism into another organism. Plants - You may not realize it, but plants are a big part of Genetic Engineering. Farmers use many techniques to insert genes from different organism around the world to help increase crop yield and to boost up proteins inside

Healthcare Associated Pneumonia vs Non Healthcare Associated Pneumonia Many germs can cause pneumonia. The most common are bacteria and viruses in the air we breathe. The human body usually prevents these germs from infecting your lungs, but sometimes these germs can overpower the person’s immune system, even if the person’s health is generally good. Pneumonia is classified according to the types of germs that cause it and where you got the infection (Staff, 2015). Pneumonia can be acquired
