Techniques for Controlling Pathogenic Microorganisms: In order to adequately address safety issues associated with fresh produce‚ it is necessary to enhance the quantity and quality of research on mitigation strategies. A few of the research needs include: Investigate traditional and non-traditional sanitizers on specific pathogen/produce combinations. Survey extensively domestic and imported products to determine the frequency of public health microorganisms on specific produce items. Survey

Pathogens are bad microorganisms that cause diseases which make you unwell if gets into your body‚ some of these are bacteria and viruses. Bacteria cause infections like TB‚ legionnaires and flu and viruses cause Hepatitis B‚ measles‚ mumps and more. Bacteria often produce toxins which affect the body‚ while viruses take over whole the cell and then destroy P2 Explain how pathogenic micro-organisms grow and spread? Pathogen microorganisms grow if all right conditions are in place for it to expand

In these controls S. pneumonia shows alpha and beta hemolysis while S. aureas and S. epidermis showed beta and gamma hemolysis respectively.

Pathogenic Micro MLST assignment 1. MLST uses the sequence information within a set of housekeeping genes to determine the type of the organism. For each gene the dissimilar sequences are noted to be different alleles. MLSA is very similar to MLST but uses linked sequences to derive a phylogenetic relationship. MLSA is generally used to progress species descriptions whereas MLST is used with species that are already distinct. In this lab we are performing MLST. 2. The 16s rRNA gene is highly conserved

A pathogenic or an infectious disease is caused by an external infectious agent or pathogen such as viruses‚ bacteria‚ parasites and fungi. These pathogens are found in water‚ soil and air and a human body can be infected from drinking‚ eating or touching something infected with germs. Examples of a bacterial pathogenic disease are pneumonia and gonorrhea‚ while viral pathogenic diseases include influenza and measles. An example of a parasitic pathogenic disease is malaria‚ while an example of

Waterborne diseases are often caused by parasites which are directly transmitted through consuming contaminated drinking water. Any water reserve‚ infested with pathogenic parasites‚ used in the preparation of food can be considered as a source of foodborne disease and could be easily transmitted through consumption of the same pathogenic parasites. These diseases commonly affect the digestive tract as well as the other vital parts of the body that may be fatal to anyone especially those who are immunocompromised

A microorganism (from the Greek: μικρός‚ mikros‚ "small" and ὀργανισμός‚ organismós‚ "organism") is a microscopic organism‚ which may be a single cell[1] or multicellular organism. The study of microorganisms is called microbiology‚ a subject that began with Antonie van Leeuwenhoek’s discovery of microorganisms in 1675‚ using a microscope of his own design. Microorganisms are very diverse and include all the bacteria and archaea and almost all the protozoa. They also include some members of the

Unknown Experiment Introduction: The purpose of this experiment is to distinguish and indentify an unknown bacterium. There are several tests that can help one eliminate and narrow down the options. The most useful test‚ and the very first one done‚ is a gram stain. This test will tell whether the bacterium is gram-positive or gram-negative. After the type of gram stain is identified‚ the tester has a wide array of differentiating tests at their disposal. Based on the results from these
