He eventually proved the relation between the anthrax bacillus and the disease by demonstrating the source from where the anthrax bacillus was frequently derived. He also distinguished the anthrax disease was different from the other diseases that resembled like the anthrax disease. He was also the one that found a remedy to the anthrax disease, vaccination. In the early days, scientist has proved that once an infections attacks the human body, the immune system responds to the change in the body. During the immune response, the body renders the disease and fights back.
As a result of the inhalation of the arthroconidia, the infection of Coccidioides immitis and Coccidioides posadasii may result in the fungal disease, Coccidioidomycosis in an individual’s lung. However, there have been cases where Valley fever was transmitted through transplanted organs or the contamination of a laceration the skin containing the fungus (Johnson, L. et al, 2014). Valley fever is not contagious from infected individuals, but rather acquired from the environment. It is essential to receive an early diagnosid because if not it can cause further complications in the future. People who have a weakened immune system has a higher chance of contracting Valley fever when exposed to Coccidioides (Jin,
Xeroderma Pigmentosum is a genetic disorder that causes hypersensitivity to the skin by exposing to UVB radiation. Skin, eyes, and nerves are the sites where the symptoms appear. In XP, DNA goes under mutation in the genes that repair that DNA. XP can be treated in various ways such as minimizing the exposure to the sun and chemical materials, protection using certain materials and surgical removal of tumors, and genetic counseling for patients and families. Introduction Xeroderma Pigmentosum (XP) is an autosomal recessive genetic disorder that causes the skin to be hypersensitive to the ultraviolet B (UVB) radiation.
Aerin Nortier Grade 11.2 Biology research project Introduction Bacteria are everywhere some harmful and others not, without bacteria the world would be nothing. In this research paper I will be discussing bacteria, anti-bacterial agents, pros and cons of bacteria and my conductive experiment on the growth and the killing of bacteria. Bacteria are single cellular organisms that most commonly reproduce through means of binary fission. They were first discovered by Anton Leeuwenhoek in 1676 and are classified as Monera in the five kingdom classification system. Anti-bacterial agents kill or inhibit bacterial growth.
The germ theory of disease, also called the pathogenic theory of medicine, is a theory that proposes that microorganisms are the cause of many diseases. Although highly controversial when first proposed, the germ theory was validated in the late 19th century and is now a fundamental part of modern medicine and clinical microbiology leading to such important innovations as antibiotics and hygienic practices. According to Louis Pasteur, germs or microbes cause disease and these germs invade the body from the outside through air, water or the food that we take in. The human blood is sterile and can only be infected by outside microbes; these germs are monomorphic, that is, they have only one form and can be identified by species. Thus, specific diseases are caused by specific germs.
INTRODUCTION: Bloodborne pathogens are microorganisms that present in human blood and they can cause diseases. These pathogens include: – Viruses such as hepatitis B (HBV), hepatitis C (HCV) and human immunodeficiency virus (HIV), also, parasites such as malaria and certain fungi. Sharp-tools, needle-sticks and other apparatus-related injuries may expose stuff to bloodborne pathogens. To eliminate the risk of occupational exposure to bloodborne pathogens, implement an exposure control plan for workers on their worksite with enough details on protection measure. The plan must also describe how a worker will use personal protective, work practice controls, clothing and equipment, employee training, medical surveillance, hepatitis B vaccinations, and other provisions as required by Occupational Safety and Health Administration (OSHA)'s Bloodborne Pathogens Standard.

Specific resistance is directed against a particular type of microorganism and is a one of the most important characteristic of the immunity. The Immune System is a system of biological structures that processes in an organism that protects in diseases. It is functioning properly if it has a wide variety of agents known as pathogens from the viruses and parasite worms, and known them from the organisms healthy tissue.
ASSIGNMENT Infectious diseases are conditions triggered by organisms which can be a virus, or bacteria, fungi and parasites just to mention a few. It is been confirmed from research and findings that many organisms live in and on our bodies even without us knowing them. Many of which are harmless or even helpful, but under certain conditions, tweaked or not, some may become harmful to our bodies and wellbeing ( (Mayo, 2014)).History of infectious diseases dates back to the bible during the Levitical era as recorded in the bible in the book of Leviticus, which says “The person afflicted with an infectious skin disease is to have his clothes torn and his hair hanging loose, and he must cover his mouth and cry out, 'Unclean, unclean! '”(HCSB,
For example, the anopheles mosquito is a vector for malaria, filariasis, and arboviruses. It pierces its mouthpart on the skin and feeds on the hosts. The pathogens carried by the mosquito, which are located within its salivary glands, are transmitted as the mosquito is feeding on the host blood. This enables the mosquito to directly transfer the pathogens into the blood stream of the host. Another example of an arthropod vector is the sand and black fly.
Thus, mosquitoes born comprise identical viruses as adult mosquito or as their mother (Anupong Sujariyakul et al., 2005). Water quality contributed the profusion of Aedes species in University Kuala Lumpur studies (Chen et al., 2009). Mosquitoes may live in a diversity of habitations with fresh water, salty water, or any water clear, muddled or contaminated except in oceanic habitats with high concentration of salt. The clean water such as rain-filled containers in moist tropical zones are commonly breeding sites for some Aedes species while with contaminated water mainly on-site sanitation systems with immobile water are favoured place by Culex species (Saleeza & Azirun,
