discovery of mycobacterium tuberculosis by a scientist named Robert Koch has brought a chance of decrease. Mycobacterium tuberculosis (MTB) is an etiological agent or pathogenic bacteria that cause most of the tuberculosis. It is a small rod shaped bacillus which can survive in a dried or disinfected state for several weeks thanks to its thick lipid cell wall. Moreover‚ its thick lipid wall allows them to survive in the macrophages by impeding the fusion of lysosome with phagosome. This trouble-making

Pneumonia refers to a serious type of lung infection. It’s often a complication of the common cold or flu that happens when the infection spreads to the lungs. Pneumonia during pregnancy is called maternal pneumonia. Pneumonia is considered a serious and potentially fatal illness for anyone. Certain groups are at a higher risk of complications. This includes pregnant women. The best way to treat and prevent complications from maternal pneumonia is to see your doctor at the first sign of an illness

There are many reasons for identifying an unknown bacterium. The reasons range from medical purposes‚ such as determining if the unknown could cause ailments in living things or knowing what microorganisms are needed to make antibiotics to other purposes such as knowing the exact microorganism has to be used to make certain foods. This experiment was done by applying methods in order to identify an unknown bacterium. An unknown bacterium was handed out by the lab instructor. The methods that

methods‚ the shape of the bacteria were easier to determine is some slides. Cocci could be seen in the wet mount of yeast‚ but in the wet mount cheek smears it was not that easy to see the morphology of the cells. The plaque smear have cocci and bacillus. On the direct stain slides the cheek smear and the yeast slide have cocci. Also on the yeast slide with indirect stain cocci were observed. The quality of the dye will determine the outcome for the difference in direct and indirect stains.

Gram Stain: The important part of this experiment is being able to determine a bacterium based on its cell wall structure. It also helps indentify if the unknown organism is a Gram positive or Gram negative. This is the initial step that must be taken before any other lab procedure may continue on to ensure the purity is present‚ the arrangement of the cells‚ and the shape the cell has. The staining of the cell starts off with using the primary stain‚ Crystal Violet which is a purple color‚ to begin

Escherichia coli O157:H7(E-Coli) is an emerging cause of food borne illness. An estimated 73‚000 cases of infection and 61 deaths occur in the United States each year. Infection often leads to bloody diarrhea‚ and occasionally to kidney failure. Most illness has been associated with eating undercooked‚ contaminated ground beef. Person-to-person contact in families and child care centers is also an important mode of transmission. Infection can also occur after drinking raw milk and after swimming
