treated right away. One of the deadliest types of viruses are Blood borne pathogens. Blood borne pathogens are normally transmitted to a human by a bodily fluid from a contaminated person. They can enter your body through open cuts, mucus membranes, skin abrasions or even sharing needles. Human Immunodeficiency Virus (HIV), Hepatitis B and Hepatitis C are the most common types of blood borne pathogens. These 3 types are very deadly to humans. These pathogens have been affecting humans for a very long…

discovery of antibiotics, they have become the miracle treatment for all types of infections, specific and non-specific. Even though antibiotics are only effective when treating bacterial infection, many seek them for viral infections such as the common cold, etc. Hence, this reckless practice has inadvertently contributed to the rising trend in drug-resistance microbes, AKA "Superbugs." This is a twofold problem; in that, drug-resistant superbugs and the abuse of antibiotics are both major health concerns…

Introduction There are many types of pathogens that cause diseases and illnesses. Parasites are one of these pathogens. A parasite is an organism that needs a living host to survive. There are multiple species of parasites that are known today and each one is unique. Medicine has advanced throughout the years, but not all illnesses and diseases can be cured. Parasites can typically be treated with antiparasitic and other types of treatments. Parasites can infect multiple organ systems such as the…

Emergence of multiple drug resistant pathogens is a major concern for clinician’s worldwide. Limitations in discovery of new antibiotics and development of drug resistant microbes necessitates the search for new antimicrobial agents which can control the spread of drug resistant pathogens. Generally third generation antibiotics control most of the pathogenic microorganisms at low doses but fail to control the multiplication of multiple drug resistant (MDR) strains at those doses and require higher…

of water-resistant sunscreen are tested to see which maintains their SPF the most in water, then Coppertone will have the best results, because it has performed well in multiple tests, including a report done by Consumer Reports where it did best out of the sunscreens that will be tested. An independent variable is what is varied during the experiment: it is what the investigator thinks will affect the dependent variable. Therefore, the independent variables are the types of water-resistant sunscreen…

In order to solve cancer problems, a variety of anticancer drugs produce that can treat or target carcinoma cells or discover tumor growth in human tissue (Colditz 2015). 5- Fluorouracil (5-FU) and Cetuximab are important examples of anticancer medicine; therefore, it is important to understand the drug target and mechanism of action of anticancer drugs. The main purpose of this essay is to explain the importance of the various mechanisms of action of cetuximab that ensure selectivity, efficacy and…

involved in the antibiotic resistance problem; the transportation of resistant strains among nations. Resistant bacteria may survive in the hospital environment. This is increased when health care professionals do not wash their hands between patient contacts. This is expressed as the unintentional spread of resistant bacteria from one patient to the next. The arrival of travel through the air has brought to surface that resistant organisms may spread from one place to another. Venereal diseases, such…

Aniruddha Acharya Term paper – BIOL 554 Spring 2015 Instructor – Dr. Don Ennis Due date – 4/27/2015 Title - Evolution of drug resistant Mycobacterium tuberculosis. Introduction Bacterial pathogen Mycobacterium tuberculosis causes tuberculosis a complex granulomatous disease which is a global health concern. It is a very slow growing bacteria, thus is extremely time consuming to culture in laboratory. It can survive the attack of the immune arsenal of our body; can successfully hide inside the macrophage…

Microorganisms form part of our normal flora, however they can become pathogens where their main role is to survive and multiply, often at the expense of the host. Pathogens cause infectious diseases depending on their virulence; this was first realised when Louis Pasteur discovered microbes contaminated wine, causing it to go sour. He wondered how microbes affected humans; however it was Robert Koch that linked the contamination of microbes to the cause of infectious diseases. Between them they…

and Prevention (CDC) defines multi-drug resistant organisms (MDROs) “as microorganisms, predominantly bacteria that are resistant to one or more classes of antimicrobial agents” ("Management of multidrug-resistant organism," 2006). The following list represents widely known MDROs: MSSA, or “Methicillin Sensitive Staphlococcus Aureus”, which responds well to typical antibiotics; MRSA, or “Methicillin Resistant Staphylococcus Aureus”. This bacterium also resistant to oxacillin and cefoxitin medications;…
