Introduction Streptococcus pyogenes is a bacteria responsible for a wide range of diseases. They include pharyngitis, impetigo, a skin infection, scarlet fever, rheumatic fever, and toxic shock syndrome (TSS) (Burch, 2008). However, the focus of this research will be on necrotizing fasciitis (NF). Although necrotizing fasciitis is rare, it can be lethal. It is commonly known as “flesh-eating bacteria” (touching base, 2001) for its ability to destroy the skin tissue. For the most part, it is…

- Pseudomonas syringae and the type III secretion system: P. syringae is a gram-negative, rod-shaped bacterium responsible for many diseases on woody plants. It acts opportunistically targeting plants wounded from abiotic or biotic factors. P. syringae is responsible for some severe crop diseases such as bacteria speck, spot, and blight of tomato and soybeans. Interestingly, it has a vast host range with over 50 pathovars. The success of the pathogen is attributed to its specificities (Sarkar &…

album “Yvonne De Carlo Sings,” go public. From the late 1950s and early 1960s, she made appearances on several TV series such as The Virginian and McLintock, starring John Wayne. In 1964, she had a role in a film called Law of the Lawless, with John Agar and Dale Robertson. In 1967 and 1968, she returned to the making of westerns, where she starred in Hostile Guns and Arizona…

CHAPTER THREE MATERIAL AND METHODS 1. PHYSICO-CHEMICAL CHARACTERCITICS: The effluent collected were analyzed in the laboratory for pH, acidity, alkalinity, salinity, total dissolved solid(TDS), conductivity, total hardness, calcium hardness, magnesium hardness, total solid, total suspension solid, turbidity, BOD, DO and COD using standard methods (APHA,2005). A.DETERMINATION OF pH: The electrode of pH meter was calibrated with standard buffer solutions of pH 4, 7 and 9. The electrode was then…

and other scientists that were his assistants. In his new and improved lab, he continued to work on his bacteriological methods. He invented some new methods. One was planting pure cultures of of bacteria on a solid media, such as the potato. Also on agar that was kept in a special kind of flat dish invented by his colleague. That is still in use. Also, he figured out a way to stain bacteria. This made it easier to be seen and to be identified. The result of this was the beginning of methods by…

all organisms from the list that do not provide significant results for the identification of the unknown specimens. Journal Entries: April 17, 2018. Today we began the unknown project. I obtained the unknown broth tube #15. I used two Tryptic Soy Agar (TSA) plates in order to make a streak plate. The streak plate is used to separate the two different bacterial organisms that were present in the broth. The plates were placed in the incubator at 37C and in 48 hours there should be isolated…

The Specimen Reception – where I spent most of my day-to-day work – is part of the Lab-Med group that is situated in the Central Pathology lab, and is made up of the biochemistry laboratory, the haematology laboratory – which includes cryobiology and coagulation, the microbiology lab, the histopathology lab – which includes cytopathology, the immunology lab, cancer molecular diagnostics, and transfusion medicine, as well as the Irish mycobacterium reference lab, and the national MRSA reference…

Creating a child is a joy many people get to experience. This child is a mix between its parents. Now scientist have figure out a way to genetically alter a baby, to fit the parents wants. A genetically altered baby is something some people have only dreamed about, but now, has become a reality. Scientists have discovered a way to alter human genetic traits and produce the perfect offspring. Although it is still in the experimenting stage, it should be possible within the next few years.…

Hypothesis: I hypothesize that if we replace infected host trees (avocado) with uninfected host trees (apple trees), the number of trees infected with Fusarium dieback will decrease because apple trees do not provide enough water for beetles and fungus to live inside them. Introduction: An invasive beetle—The Polyphagous Shot Hole Borer (PSHB)—is the factor that causes a serious disease in trees called Fusarium Dieback (FD). PSHB is a native Southeast Asia adult female beetle that carries…
