food. A pathogen “is a biological agent that causes disease or illness to its host.” (www.sciencedaily.com/terms/pathogen.htlm) There are many ways foods can be in contact with pathogens. First of all, the air and soil has many pathogens and bacteria floating in it that can easily come in contact with our food. If the food is packaged, there may be pathogens from the packaged materials. Also pesticides used to preserve foods is very commonly used. Materials and Methods: First I chose to

organisms to break down harmful chemicals and pollutants in order to return the environment to its original natural condition. This would include an environmental problem such as contaminated soil or groundwater. In a non-polluted environment, bacteria, fungi, protists, and other microorganisms are constantly at work breaking down organic matter. What would occur if an organic pollutant such as oil contaminated this environment? Some of the microorganisms would die, while others capable of eating

Zainab karimu Unit 37 P4 I will be explaining active and passive artificially acquired immunity in form of a table. Immunity is the protection of the body from infections from viruses and bacteria. Acquired immunity is a type of immunity also known as the third line of defence, it is the immunity produced when the human body has been infected by an antigen which triggers the production of antibodies. There are two types of acquired immunity which are active and passive acquired immunity

BIOTERRORISM Name: 1. Introduction Historically, infectious disease outbreaks brought about by microbial species against human beings have caused far more mortality rates than war itself. Numerous cases of disease outbreaks in the past have been a major concern to health authorities, although such concerns have been partially addressed in the recent past. Examples of disease outbreaks in the past include: the infamous Bubonic Plague of the 14th century in Europe that led to the death

give a background on the characteristics, pathogenicity and some uses of one of the identified unknowns. II. Introduction In this lab report I will discuss how I came to find my two unknown bacteria. Each bacteria have undergo many different test to eventually identifying both bacteria. We understand that bacteria6 the discussion on the role of microbes in human welfare may be divided under two headings - good and bad 6. Microbes as we know are capable of both good and bad as for as

Task #1: Fungi Nicole Keane Clinical Microbiology C453 1/6/2016 Introduction For this experiment, five food substrates were chosen to compare fungal growth placed in the same environment over a period of seven days. The five foods that were used for this experiment were grapes, strawberry, bread, American cheese slice, and a green pepper. Materials and Methods The materials needed for this experiment were five different food items, five small plastic bags, and five wet paper towels

Let us say something about Energy that I know while I was in high school Physics class. Energy is usually defined as the ability to do work. In general; we would say that energy is fundamental entity whose availability and flow are required for all phenomena, natural or artificial. Energy neither be created nor destroyed; rather it is changed from one form to another. That means mechanical energy, such as the kinetic energy of motion can be converted to heat energy. Let’s come to the type of energy

(Campbell, 2003). They are complex organisms with many cells and are divided into vertebrates and invertebrates. Monerans are one-celled organisms and do not have a nucleus. This kingdom is mostly composed of bacteria that are further grouped into bacteria and cyanobacteria. In addition, bacteria are the most common organisms on earth. Protists are mostly single-celled organisms that have a nucleus. They usually live in water. Some protists move around, while others stay in one place. Examples of protists

Botox Botulinum toxin offers relief to neuro-muscular disease patients Clostridium botulinum is a bacterium that produces neurotoxin which can cause dead food poisoning. Yet, this poison has been used as a tool to fight wrinkles. Botulinum toxin marketed in therapeutic doses as “Botox”. Initially, it was used to treat neuro-muscular disease with involuntary muscle contraction symptopms. This problem arises from too little inhibitory input to motor neuron, as compared to excitatory input,

MULTIPEL MYELOOM : Prof. Dr. Michel Delforge Hematologie Universitaire Ziekenhuizen Leuven Samenvatting De perspectieven voor patiënten met multipel myeloom zijn de voorbije jaren sterk verbeterd. Gedurende de voorbije jaren is de behandeling geëvolueerd naar een geïntegreerde aanpak, gebaseerd op beter ziekte-inzicht en nieuwe geneesmiddelen. Een eerste revolutie was er begin van de jaren negentig door de introductie van de hoge dosis chemotherapie gevolgd door autologe stamceltransplantatie
