The Factors Responsible For Infectious Disease

Compare and contrast the ways that fungi "eat" with the ways that animals digest, and absorb their food: Fungi have specialized roots called hyphae that don't grow in width, but in length as to maximize surface area ratios, a mass of hyphae is called a mycelia

living hosts. Bacteria is a Prokaryotic cells that are present in the soil, air, water and in many

Health care workers are around infectious diseases a lot while they are working. These workers include physicians, nurses, technicians, clinical laboratory workers, first responders, building maintenance, security and administrative personnel, social workers, food service, housekeeping, and mortuary personnel. Many of the health field is exposed to infectious diseases all the time.

A mushroom is a type of fungus. Unlike plants, they don’t need sunlight or seeds to grow.

Two hundred years ago the causes of infectious diseases were unknown, and so our ability to control or cure them were almost non-existent. During the late 19th and early 20th century a number of scientists contributed important ideas and findings which lead

Infectious disease were shaped serious health issues in the world until beginning of 20th century, some disease as cholera, plaque were distribute significant proportions of the populations of European cities. (Barreto, Teixieira & Carmo, 2006).

Microbiology is a study of small living organisms that are hard to be seen without using the microscope; such as bacteria, archaea, viruses, and protozoa. Fungi are different, a majority are big enough for us to see. They’re all have a long history of living on Earth, the scientist also believes they are the first living things that are existing way before mammals or human. Those microorganisms are everywhere around us, some are harmless and some can cause serious diseases. The condition and environment are different for every microorganism, some can live in the cold and a few can live in an area where hardly any living things can survive in. However, the bacteria that I found the most interesting in is Alcaligenes faecalis bacterium because

Microorganisms are microscopic organisms that can be found anywhere in the environment. They can be bacteria, fungi, archaea or protists (Leon-Sicairos et al., 2015). Some microorganisms can attack one’s immune system and cause diseases such as chlamydia, rabies, leprosy and meningitis.

Fungi are nonphotosynthetic and must absorb nutrients from surrounding organic matter. Most fungi obtain their food from dead organic matter and thus considered saprophytes, however, a relatively small percentage called parasites derive their food from other living organisms. Fungi may be unicellular (yeasts) or multicellular (mushrooms) and their cell walls usually contain chitin. They may produce sexually or asexually by means of spores. They are major factor in food deterioration however; benefits include the aid in production of pharmaceuticals, food, and drink (Royse, 2003). Mould growth is affected by factors such as moisture content, nutrient availability, temperature, pH levels, light, and

Many diseases exist in this world that are potentially life threatening. We must be aware of signs and symptoms, and how to diagnose these diseases if we are going to keep an epidemic from occurring. More importantly, education on how these diseases are transmitted and preventive measures to keep these diseases under control are of the utmost importance.

Infectious diseases are caused by agents that invade the host and produce an alteration in the state of health. These agents include viruses, true bacteria, protozoa like bacteria, fungus like bacteria, rickettsial organisms, chlamydial organisms, fungi, and yeast like fungi, mycoplasmal agents, and internal and external parasites. In addition to these causative agents, stress must be included as a cause or condition for the development of disease.

When you think about infectious diseases, think about all the outbreaks. In 1989 there was a major outbreak of measles in which more than 55,000 cases were reported, and 136 people had died all just from measles. Vaccines did not start to appear until the late 90’s early 2000’s. It is also cheaper to prevent a disease then the treat it. We are actually very lucky that we have the technology today that gives us the opportunity to prevent harmful diseases. In infectious diseases there are many ways we can have complications, like not having the right vaccine, or how big the treatment is will be, and finally will there be a rise of infectious disease. In the following essay, I will hope to educate you more in showing you my findings.

A microbial colony is a group of cells that you can see with the naked eye and are genetically the same because they come from a CFU-which is usually one cell

Rubella virus is a member of the Togaviridae family though is its own genus, Rubivirus. Rubella is caused by the Rubella virus which can be found in the blood, stool, or throat of an infected individual (change). There is currently only one genetically stable serotype of Rubella, however a phylogenetic tree analysis of nine virus strains confirms the existence of a minimum of three distinct genetic lineages (Parkman, 1996). The virus is spherical in shape with a diameter of 50-80nm and is a 20-faced nucleocapsid. The core surrounding the single-stranded, positive-sense RNA genome has hemagglutinin-containing surface projections and is also surrounded by a lipoprotein envelope. There are three major structural polypeptides: E1 and E2 membrane glycoproteins, and a single nonglycosylated capsid protein associated with RNA. The first envelope protein, E1, is responsible for viral hemagglutinination and neutralization while E2 is categorized into two forms: E2a and E2b. There are two forms because of the differences in glycosylation and these differences indicate different strains of Rubella (Parkman, 1996).
