Bacteria, Viruses And Diseases

Pathogens are everywhere. They are in people, animals, and the environment. Pathogens come in a wide variety. The types are fungal, bacterial, viral, and other parasites. All pathogens can be dangerous, but two of them are more dangerous. These two types that more dangerous are fungal and bacterial. While both fungal and bacterial pathogens cause illness, they differ in the way they are transmitted, the way they are treated, and the diseases they cause.

I must take all reasonable steps to ensure that the PPE is returned, once worn to the appropriate location and that the items are not removed from the workplace.

Bacteria are unicellular organisms that replicate and multiply by mitosis. Fungal infections occur due to fungi including organisms such as dermatophytes and yeast, which are made up of structures called hyphae. On the other hand, viruses are parasites and therefore require a host cell to replicate and spread.

Explain two ways you help in preventing the spread of pathogens on a daily basis. (4 Points)

What are some common pathogens that cause HEENT infections? Do you recommend a limited or an involved use of antibiotics in treatment of these diseases and other unconfirmed bacterial illnesses and why?

A virus is a capsule containing genetic material, even smaller than bacteria. The main task of virus is to reproduce. However, viruses need a suitable host to

Bacteria are single-celled microorganisms. Their cell structure is very unique because they don't have a nucleus, and most bacteria have cell walls similar to plant cells. They come in different shapes including rods, spirals, and spheres. Some bacteria can "swim" around using their tails called flagella. Others just stay still or move with the others. Most bacteria aren't dangerous, but some can make us sick. These bacteria are called pathogens. Pathogens can cause diseases in animals and plants. Some examples of pathogens are food poisoning, pneumonia, and tetanus. This online

What are the differences between bacterial, viral fungal and parasitic infections? How is each treated?

Staphylococcus aureus- Is a facultative anaerobic, Gram-positive, salt positive, cocci shaped bacterium. Staphylococcus aureus is found as normal part of the skin floral in the nasal passages and on the skin. An estimated twenty percent of people naturally have harmless Staphylococcus aureus on their skin and are long-term carries for Staphylococcus aureus. Staphylococcus aureus is the most common strand of Staphylococcus in humans to date, spread through skin to skin contact or even skin to object contact that an a person infected with Staphylococcus aureus has touched. Staphylococcus aureus is coagulase positive, which induces clumping of the cells and of the blood. Staphylococcus

Bacteria is everywhere, and since bacteria is considered as germs, these germs can get people sick. Therefore, what is the best way to kill bacteria? Instead, of using regular disinfecting wipes, I chose 91% Isopropyl alcohol; it’s less expensive than the common disinfecting wipes. It most likely kills bacteria by “kill[ing] cells by denaturing cell proteins and DNA, interfering with cellular metabolism, and dissolving cell lipo-protein membranes” (PubChem Compound Database). In other words, alcohol kills bacteria by first making the outer cell membrane lipids more soluble in water, which makes the cell lose its structure and fall apart. While the cell membrane is disintegrating, the alcohol is allowed enter and denature the proteins within

Medical professionals are often faced with the task of determining what type of microorganisms are causing infection in their patients. In order to isolate different types of bacteria in a patient sample, different tests must be performed. Bacteria can be differentiated based on characteristics such as whether or not they ferment lactose, are motile, or produce urease. It is important to know which tests to run so the minimum amount can be used to identify the causative agent. This helps reduce expenses and yields quicker results so treatment can be administered if necessary.

For as long as humans have been on this planet, the microscopic life forms that we call germs, or pathogens, have been here too. For all this time they have been multiplying in the soil, in the water, and in our bodies. They are in the mouth, on the skin, and even in important organs. But that is not always a bad thing, because humans could not live without germs. Some germs, or "microbes" help digest food, while others produce vitamins. Most of the time, people and germs coexist peacefully; in fact there are trillions of germs on you right now.

There are five main types of microorganisms that are FUNGI, BACTERIA, PROTOZOA, ALGAE and last but not the least VIRUSES.

Microbiology is the study of microorganisms; whether it is bacteria, fungi, algae, protozoan, viruses or archaea (Leboffe & Pierce, 2006). Microbes come in all different structures and classifications. Before the 17th century the idea or microbes existed, but was never proven until a scientist provided something that allowed us to see what the naked eye alone could not see (Pelczar, 2015).

Microorganisms include bacteria, archaea, protozoa, fungi, algae and some members of the kingdom Animalia such as rotifers and planarians. Viruses also fall under this category, i.e., microorganisms but some researchers even consider viruses as non living (Rybicki 1990) (LWOFF 1956).
