INFECTION CONTROL Pathogen- Infectious agent Colonization- If microorganism is present or invades host‚ grows and/or multiplies but does not cause infection. Communicable disease- if infectious disease can be transmitted from one person to another. -Symptomatic-if pathogens multiply and cause clinical signs/symptoms. -Asymptomatic- if no s/s are present *CHAIN OF INFECTION: 1. An infectious agent or pathogen 2. A reservoir or source for pathogen growth 3. A portal of exit from the

Resistant Bacteria: What is it‚ how to prevent it and who it affects? In the United States alone‚ about 23‚000 people die from antibiotic resistant infections yearly. It is also one of the top 15 most dangerous illnesses in the country (United States House of Representatives). Antibiotic resistance is when bacteria develops a different response to an antibiotic that is its ancestor bacteria. Slight changes in bacteria enable the antibiotic to work and successfully cause an infection without a

Protists are plantlike‚ animallike and funguslike. A virus is a microscopic particles that make up either DNA or RNA core covered by a protein coat. Viruses are so small an electrn microscope

MANIPULATION OF BACTERIA INTRODUCTION: In this experiment that we performed‚ there were many methods that were used to help us manipulate and identify the bacteria E.coli on a MacConkey agar plate. The first part of the experiment involved the methods of manipulating‚ identifying and counting the bacteria and the second part was to find out whether the bacteria E.coli was the only type found in the given area by gram staining. E.coli was the chosen bacteria for this type of experiment. It is

Parasites have evolved in a very specific and selective way throughout generations. Specific parasites have specific factors that influence their site selection process and that work in favor for the parasites. One important component that influences the parasite to become site specific is being host specific‚ which in turn affects the ability of extracting resources. The more efficient it is in extracting resources the better the chance of reproducing‚ which then increases the fitness of the parasite
