Pathogen

kind. Hospitals, clinics, and care homes host a vast variety of bacterium, viruses, and fungi. These pathogens can survive on almost any surface such as tables, chairs, beds, and especially clothes. When healthcare workers, patients, and visitors have exposure to contaminate surfaces (i.e. touching a doorknob), they will carry the pathogen on their person, almost certainly spreading the pathogen to another surface or individual.…

types of micro-organisms these are bacteria, archaea, fungi, protozoa, algae, and viruses. This essay aims to analyse micro-organisms and disease. First the key features of the main categories of micro-organisms and the roles of commensals, and pathogens will be explained respectively. Then mode of transmission, portals of entries and exits of microbes are explained. How our body defence mechanisms prevent from the infections will be discussed after the logical sequence of events that occur from…

Infection Control Risk Assessment (ICRA) In this world, humans are often oblivious to pathogens in the workplace, including diseases and illnesses that could kill hundreds of people every day. One often unthought-of risky setting would be health care facilities when they are in their very first stages, the construction stage. Nevertheless, this stage in time becomes a critical point to stop most infections from beginning in the first place, and if done right will keep later patients from…

Health Administration (OSHA) sets the standard for preventing work-related injuries, illnesses, or deaths (Baker). When taking a look at some of OSHA’s regulations pertinent to the dental community, they include but are not limited to: bloodborne pathogens, a written exposure…

In a healthy individual, the bloodstream remains sterile – free of any pathogens. The immune system, which is responsible for defending the body against pathogens, is a very complex and vital body system. The immune system involves both innate and adaptive immunity. Innate immunity functions as the “first responder” system of the body. The skin, the mucous membranes are the first line of defense in innate immunity. The skin and mucous membranes serve to prevent microbes from…

developed bilateral discharging sinuses over the hips and underwent several incision and drainage procedures.” Potential Pathogen In the case of the individual that developed an infection after receiving bilateral prosthetic hip replacement, the pathogen that appears to be the most likely culprit is Staphylococcus aureus (S. aureus). The patient likely did not…

3. As you are working in the lab, you discover a new TLR (TLR23), which recognizes a pathogen of significant human health concern. Your task, whether or not you choose to accept it, is to fully characterize the molecule. If you are successful, you will definitely finish graduate school and move forward in your career as a scientist. (30 pts) a. Design an experiment to determine if “TLR23” recognizes a bacteria or a virus. What results do you anticipate and what experimental difficulties will you…

Bacterial wilt is a serious economic disease cause problem in several countries where potatoes are cultivated over large areas for consumption and/or economical exportation crop like Egypt. Ralstonia solanacearum is the most devastating bacterial pathogens which infect more than 50 botanical families. The bacterium is found worldwide, mainly in tropical and subtropical areas, but also in warm temperate countries and even in some cool temperate regions (Hayward et al., 1998 and Peeters et al.,…

search for new antimicrobials from other sources including plant extracts, these plants then emerged as compounds with potentially significant theatric application against human pathogen (Kathe et al., 2003). Most of the investigations show that medical plants used for treating many diseases that are caused by many pathogen, due to its chemical components (Hamilton-Miller, 1995; Toda et al., 1989). On the other hand, in laboratory tests, the chemical eugenic, has been found to be a weak tumor…

The adaptive immune system is more specialized in terms of its defense mechanisms and ability to develop memory of specific pathogens. Once a pathogen has been killed, T-cells and B-cells continue to produce, which allows for a stronger and faster response the next time the body is challenged by that particular pathogen (Mayer,…
