Abstract The purpose of this experiment was to study the transfer of genetic information on plasmid F’lac by using Escherichia coli. Plasmid transfer was measured by using two different methods. The first one was by using selection and contraselection with three antibiotics: streptomycin(which was replaced by naladixic acid for the second part of the experiment), […]

Analysis & Discussion The primary objective of this investigation was to test ultraviolet radiation as an alternative disinfectant for Acanthamoeba in its more resistant cyst form. A previous study had already shown that multipurpose solutions were ineffective compared to hydrogen peroxide based systems at eliminating Acanthamoeba trophozoite contaminations. 5 This was a follow-up to that […]

The HIV/AIDS Epidemic In South Africa Acquired Immune Deficiency Syndrome (AIDS) caused by the Human Immunodeficiency Virus (HIV) is one of many infectious diseases that plague the world today. According to the 2007 AIDS epidemic update put out by The United Nations Joint Program on HIV/AIDS (UNIADS) there were approximately 2. 1 million AIDS related […]

The Role of Agarase in Agar-Degrading Bacteria Abstract Agar-Degrading (agarolytic) Bacteria is physiological class of bacteria capable of utilising agar as a sole carbon source. This ability is made available by the use of agarases – enzymes which break down agarose into oligosaccharides. This physiological class branches through genii, regardless of Gram Stain status or […]

This will include: the color of the medium immediately surrounding the colonies after addition of iodine on PDA plate, whether bubbles were observed or not in the atlas test, the color of the urea slant, the color of the citrate slant, and whether the rabbit plasma remained liquid or became solid due to clot formation, […]

Hypothesis: If the most effective solution for pathogenic bacteria is household bleach, then the descending order from best to least are household bleach, Penicillin, Monoclinic, Household Disinfectant, Anti- Bacterial Soap, Erythrocyte, Sterile Filter Paper. Materials: The materials used in this lab include a agar, a Petri dish, test tubes containing the pathogenic bacteria: Staphylococcus erasures, […]

Antigen recognition allows the immune system to recognize each antigen with tremendous specificity in order to avoid an immune response to host tissues. One way in which the immune system accomplishes this is through the production of antibodies by the B-cell. Each antibody must be able to bind specifically to one part of an antigen; […]

In 1884, Arthur Nicolaier isolated the strychnine-like toxin of tetanus from free-living, anaerobic soil bacteria. The etiology of the disease was further elucidated in 1884 by Antonio Carle and Giorgio Rattone, who demonstrated the transmissibility of tetanus for the first time. They produced tetanus in rabbits by injecting their sciatic nerve with pus from a […]

Between May to July, Malaysian had been surprised by a ‘new’ communicable disease which carried a weird name, it called ‘Chikungunya’, the term is actually derived from the ‘Makonde’ word meaning “that which bends up” as referred to the stooped posture developed resulting of arthritic symptoms of the disease. It is belief that the chikngunya […]

Yellow fever is a hemorrhagic fever – meaning it is caused by several distinct families of viruses. Most people who contract the virus have no symptoms, however the few that do experience these symptoms, feel them 3 days after infected. The symptoms include: headaches, muscle and body pains, fever, chills, nausea, vomiting, fatigue, and weakness. The yellow […]

In the early years of the 20th century, rheumatic fever had a very high incidence specifically in children across the globe. As one of the common diseases that afflicts children and among the reason of most hospitalizations in pediatric wards, this disease was intensively studied. In the later years of the 20th century, the incidence […]

Objectives: To measure the different phases of growth of Escherichia coli through absorbance reading and viable count measurements To plot the growth curve of Escherichia coliIn the experiment, the different growth phases were observed through the analysis of the absorbance of broth with inoculated organism (E. coli). There was no viable cell counting done with […]

The Hot Zone by Richard Preston was published in New York in 1994, consisting of 422 pages. I would rate this book a six because of its sporadic storyline. It provided some scenes that glued my eyes to the pages and made my stomach turn inside out, but overall it was not the type of […]

Though there are well over seventy thousand true fungal species that inhabit this planet, very few of these cause diseases in humans, called mycoses. Many more fungal diseases are associated with various plants and other animals. Mycoses in humans can range from superficial infections to deep-seated systemic infections that are life threatening. The superficial mycoses […]

The aim of this investigation is to find out what effect out of two antibiotics, penicillin and streptomycin has on the growth and multiplication of two different species of bacteria. The two different types of bacteria we will be using are E-coli and micrococcus luteus. The Apparatus:* Four sterilised Agar plates,* Glass spreader,* Masking tape,* […]

Sign up now for a free trial. Date Smarter! AIDS “Somewhere among the million children who go to New York’s publicly financed schools is a seven-year-old child suffering from AIDS. A special health and education panel had decided, on the strength of the guidelines issued by the federal Centers for Disease Control, that the child […]

Being part of the Sports Medicine profession, Athletic Trainers have to be ready for anything and everything when it comes to treating their athletes. This includes recognition, evaluation, education and prevention of various problems. One specific aspect of this is having a basic knowledge of contagious diseases that is seen all too commonly in Athletics. […]

A West Nile (WN) virus was first isolated in 1937 from the peripheral blood of a woman in the West Nile province of Uganda in Central Africa. Since then, WN viruses have been reported from North Africa (Egypt, Israel), East, Central, and South Africa, Asia (India, Pakistan), Borneo, Europe (Cyprus, France, Romania) and, most recently, […]

Shigallosis are a group of bacteria that cause an infectious disease that principally affect humans and primates. Is the third most common type of food poisoning in the US after Salmonella and e.coli.it affects nearly165 million people every year worldwide with 250,000 reported and estimated 45,000 reported cases in the US alone. my research review […]

This report discusses what Hand, Foot and Mouth Disease (HFMD) is, how it is spread as well as the precautions one should take to avoid getting HFMD. There have been recurrent outbreaks of HFMD over the last few years and similar outbreaks of HFMD have also occurred in the region, namely in Brunei and Sarawak. […]

Protists are known to be the very first eukaryotic organisms on earth. The Kingdom Protista was first classified by Haeckel in the year 1866. Now, there are many known species of protists. After learning about protists in class, the group decided to observe the different species of protists found in pond water. The group prepared […]
