It moves in the body by swimming through the bloodstream. This bacteria is called salmonella and it comes from undercooked food. It goes through the mouth down to the esophagus that connects to the stomach liver and gallbladder. As it goes down it filters through the liver stomach and gallbladder all connects the intestines. Salmonella sometimes reach

microbiology lab class. It is possible to identify a mixed culture by running experiments on the unknown bacteria and taking what we already know and applying it to the results. It helps to slowly eliminate any bacteria that do not correspond with the results of certain tests. An unknown test tube labeled 94 was given to me b my instructor. The first procedure performed was an isolation of my unknown bacteria with the goal of obtaining a pure culture. This was done by streaking the unknown onto a nutrient

Olivia Teasdale Mrs. Gaspar SBI3U1 10/07/13 The Effect of Disinfectants and Antiseptics on Bacteria Growth Abstract The purpose of this lab was to determine the effect of disinfectants and antiseptics on bacterial growth. By observing the effects of 5 different inhibitors including alcohol‚ bleach‚ soap solution and distilled water‚ it was determined what antiseptic or disinfectant was able to best inhibit this kind of bacterial growth. Nutrient Agar was poured into a Petri dish with four quadrants

antibiotics are continually used as bacteria grows exponentially more resistant to them then eventually society will fall back into an era without the readily use of antibiotics. Fortunately the superbug is not currently immune to all antibiotics as some forms of antibiotics can still treat the bacteria. In years to come the superbug will become increasingly hazardous to mainstream society as it grows faster than scientists can create medication for. Bacteria are the main source for all diseases

salmonella bacteria can life for a semi-long period outside a host body -once salmonella has entered the body (through contaminated foods or coming in contact with infected feces) the bacteria will begin to grow R -salmonella reproduces asexually through binary fission Binary fission- subdivision of a cell ‚ single stranded DNA replicates then attaches to opposite ends of the cell and then the cell pulls part -Through reproduction‚ two identical cells are formed from the original bacteria -Reproduction

Bacteria are unicellular and ultra-microscopic organisms‚ yet they play an important role in nature. They are of tremendous importance to man. They play an important role in agriculture and medicine and are the basis of many industries. Some are beneficial to man directly or indirectly‚ others are very harmful as they cause various plant and animal diseases. Bacteria are considered as our friends and foes due to their beneficial and harmful activities. Their economic importance can be studied under

There are several types of staining through which the bacteria can be identified based on the color and shape. The staining methods used in the lab are Gram Staining‚ Capsule Staining‚ Endospore Staining‚ and Acid Fast staining. One of the most significant method of

Penicillin. Penicillin prevents Gram-positive bacteria from forming peptidoglycan‚ the major component of the cell wall. Without peptidoglycan‚ internal pressures cause the bacterium to swell and burst. Penicillin is not one antibiotic‚ but a family of antibiotics. The family includes penicillin F

Outcome 1 - Understand the causes of infection 1 - Identify the differences between bacteria‚ viruses‚ fungi and parasites Bacteria - Bacteria are organisms made up of just 1 cell. They are capable of multiplying by themselves‚ as they have the power to divide. Bacteria exist everywhere‚ inside and on our bodies. Most of them are completely harmless and some of them are very useful. But some bacteria can cause diseases‚ either because they end up in the wrong place in the body or simply because
