Bacteria

three types of media (LB, Nutrient agar and Mannitol salt) to see which type of plate would allow for better growth of the bacteria. Figure 3 shows a master plate with the bacteria that were isolated from the initial test plate. Master plates were also made for LB and Mannitol salt plates (data not shown), but only LB was as effective as nutrient agar at growing the bacteria, most likely because these are nutrient rich and complex media plates. The fact that the organism grew better in rich and…

An infectious disease is pathogenic microorganisms, like bacteria, viruses, parasites or fungi that cause diseases by spread, directly or indirectly, from one person to another. One infectious disease is Clostridium difficile, a nasty bacterium that affects the digestive system, specifically the colon. A disease that can start of pretty mild and lead to life-threatening inflammation of the colon. Clostridium difficile is a bacterial infection in the digestive system which has the same symptoms…

12.8 grams, while cholesterol at 13.8 grams for every 100 grams of fertilized duck egg (Table 2) (Jalaludeen & Churchill, 2006). Proteins aid in the cultivation of various bacteria whereas it is one of the basic growth components in bacterial cultivation. Moreover, the presence of cholesterol in vivo aids in nurturing bacteria and allow it entry into host cells. (Tille, 2013). Table 2 Nutritive Value of Duck egg compared to Chicken egg.…

information on the subject of biology. A plasmid is bacteria naturally containing one or more tiny circular pieces of DNA. The two genes being used in this experiment are Ampicillin and fluorescent genes. When reading about the lab, the most common thing used in the report is the “+” and “-“ at the end of different micro tubes and Petri dishes; the meaning of those are that the “+” means bacteria will spread on the plate, while the “-“ means that no bacteria will be spread on the plate.…

not serious and lasts a short time but the flu virus can cause viral pneumonia to be severe or fatal. It is especially harmful to pregnant women or people with heart or lung issues. Mycoplasma -Mycoplasma are organisms but are neither viruses nor bacteria but they have traits common to both. Mycoplasmas cause mild cases of pneumonia, most often affecting older children and young adults. Tuberculosis Pneumocystis carinii pneumonia (PCP) PCP mostly affects people with compromised immune systems,…

surface of a bacteria, the tube portion contracts, then the legs or tails of the virus inject the genetic materials into the bacterium. Bacteriophage could be used to combat bacterial diseases in the process called bacteriophage therapy. This is when viruses are injected or transported to the place of the bacterial disease, then the virus located and destroys the bacteria which fights infections. This is better than regular antibiotics because they try to kill all of the bacteria that the…

quickly questioned the ill group of people, including Mary Mallon who had exhibited a less intense form of the disease. Mr. Sober first concluded that the infection was the result from freshwater clams; however, Mary Mallon was the host for the bacteria. She continued to infect everything she came in contact with. As time went on and more people developed typhoid whom Mary cooked for, Mr. Sober began to pursue her and linked Mary as the culprit for spreading the disease. Eight of the other…

Bacteriophages are viruses that attack bacteria with the sole purpose of replication, as phages cannot do it on their own. The phage structure consists of a capsid, a protein head that houses nucleic acids, and a tail, which allows for nucleic acid transfer during the infection of bacteria. The first step in phage bacterial infection is attachment, in which the phage tails have the role of cell surface receptor localization (Rhakuba, et al., 2010). Next, the phage injects its genetic material…

brucellosis can become a long-lasting (chronic) disease. CAUSES Brucellosis is caused by a bacteria of the genus Brucella. Humans become infected when they come in contact with animals or animal products that are infected or contaminated with these bacteria. Dairy products that are made with unpasteurized milk are the…

E. aerogenes has a BSL level of 1 but can cause urinary tract infections and bacteremia (Dworkin et al., 2006). It is a motile bacteria that can move around if media allows (Smalley and Kaltz, 2003). The typical appearance of E. aerogenes on complex media is round medium colonies that are slightly raised or flat with irregular margins (Dworkin et al., 2006). On MacConkey’s agar,…
