Before this practical at A level I had previously performed a gram staining of bacteria, although I had not observed them under a microscope before. I had studied about fungal structure and growth but had not observed them under the microscope before. I had learned about small motile aquatic organisms although methods for their observation were not included in my previous study. In this practical we began first by setting up our microscopes using standard operating procedures of practice. This involved

Anthrax is a disease caused by the gram-positive, rod-shaped bacteria called Bacillus anthracis. This type of bacteria is mostly lethal. Anthrax is not contagious, meaning it cannot be transmitted from person to person. This disease mainly affects animals such as sheep, cattle and goats, when they come in contact with or ingest contaminated spores in plants, water, or the soil. However, humans can become infected when Anthrax spores get inside the body and begin to multiply. The bacteria cells begin

Enforcement programs have always been required to monitor the safety of the public and there are plenty of statistics that show an increase in compliance with established regulations as a result of enforcement. I believe that it is important to implement a mandatory food safety training requirement for all restaurant employees. The health department can enforce regulations, but education always comes before enforcement. If restaurant employees are not educated in the proper food handling, preparation

Lab Write Up Identifying an Unknown Microbe Gregory Howard 10E The isolation I was given two unknown microbes and asked to identify them. The first step was to isolate each microbe. I did this by using the streak method to apply each microbe to an enrichment culture. The enrichment culture provides conditions to enhance growth of a species. Obataining a pure culture makes it easier to identify and study a particular species. The macconkey agar plate which is used to isolate and differentiate

Foodborne Illness – Hepatitis A 1. What is the infectious agent (pathogen) that causes this infectious disease? The U.S. Government requires that sewage be treated to eliminate pathogens. This includes bath water, toilet water, and storm run-off. These fluids may carry pathogens for many water borne disease, including giardiasis and hepatitis A. This involves collection and sedimentation of sewage waters, separating solid matter (sludge) from the liquid (effluent) portion of sewage. The

SURFACE SANITATION VERIFICATION PURPOSE: The primary purpose of this information paper is to provide guidance on the use and implementation of the Charm PocketSwab( for surface sanitation verification in commissaries located throughout EUCOM. BACKGROUND: ATP (adenosine triphosphate) bioluminescence has been used in the food industry for over 10 years to quickly assess and monitor microbial contamination on surfaces. ATP is an excellent means of identifying “hot spots” or areas with organic material

Webster’s dictionary defines a disease as “a condition of the living animal or plant body or of one of its parts that impairs normal functioning and is typically manifested by distinguishing signs and symptoms; a harmful development.” Add that with the definition of infectious disease from our AS Level and A Level Biology book - “...transmissible, or communicable diseases; diseases caused by pathogens that can spread from infected people to uninfected people” - and it’s no wonder why scientist and
