Zainab karimu Unit 37 P4 I will be explaining active and passive artificially acquired immunity in form of a table. Immunity is the protection of the body from infections from viruses and bacteria. Acquired immunity is a type of immunity also known as the third line of defence, it is the immunity produced when the human body has been infected by an antigen which triggers the production of antibodies. There are two types of acquired immunity which are active and passive acquired immunity

Why Does The Same Drug Affect People Differently? By: Brianna Morse Basic Genetics and the Inheritance of Genes What are Genetics? Have you ever wondered why you have your mother’s eyes of your father’s hair color? The simplest answer for this would be genetics. Genetics is the study of heredity or inheritance. Genetics helps to explain how traits are passed from parents to their young. Parents pass traits to their young through gene transmission (for example hair and eye color, shape of ears

useful in water purification because the small molecule contaminates are passively absorbed by the nanoparticles. This discovery is superior to current water purification systems in place like ultraviolet radiation (UV) that is sufficient to kill bacteria however, more absorption occurs on small nanoparticles (Fletcher, 2015). However, nanoparticles can only be used to filter surface and groundwater because cations in saltwater tend to make the particles bind together, losing the effectiveness of

CS#13 You work in a small family practice in rural Virginia, (much better than Texas!). A man in his early 50s comes in with a complaint of intermittent fever (102-103 F) and headache for the past two weeks. The physician examines him and takes a history. The only clinical finding is a wound about the size of a quarter on his right thumb. Axillary lymph nodes are swollen and tender. The man says he cut himself while skinning a rabbit three days ago. On the basis of these observations the

found in nearly all parts of the environment, foods, and even inside in all organisms. Majority of this bacteria is harmless, but it could also be potentially beneficial and even disadvantageous. Research has proven that some types of E. Coli can be the source of illness such as diarreach urinary tract infections, and many other varieties of illnesses. It is possible you many be exposed to this bacteria from the contamination found in our daily food and water (It is commonly present in raw and uncooked

about 5,000 viruses have been described in detail. [Secondary Source] Although there are millions of different types, viruses also undergo cycles in order to reproduce and harm and/or help organisms. There are two types of viral cycles known to men, the lytic cycle and the lysogenic cycle. In the lytic cycle the virus attaches itself to the host cell and nucleic acid is inserted into the cell. Next it makes copies of DNA and capsid and more viruses are assembled. Finally the viruses are released

biology and genetics b. Defining what a microbe is: * a microbe is a living organism that requires a microscope to be seen c. Where did microbes come from? Evolutionary origins, fossil evidence; prokaryotic cells eukaryotic cells * bacteria is the oldest known life form. Oldest datable geographical evidence was 3.8 bya * eukayotic cells arose from divergent prokaryotic lines. Endosymbioses came from mitochondria and chloroplasts. Unicellular types came from simple multicellular

June Monday 9,2014 Patti Cantamessa Abstract Infectious pathogen in salmonella is salmonella enterica bacterium. Salmonella are motile, non-spore forming, gram negative, rod-shaped bacteria. There are approximately 2,400 types of salmonella. (Schneider, 2013) There are many different kinds of this bacteria, salmonella serotype, typhimurium and salmonella serotype enteritis are the most common types. Salmonella is wide spread in the environment and is associated with all animals’ species including

difference between a bactericidal and bacteriostatic agent? Between sterilization and disinfecting? The difference between the two is that bactericidal kills bacteria directly. While bacteriostatic stops the bacteria from growing. Bactericidal will injure the plasma membrane and the cell will leak out, killing it. Bacteriostatic stops bacteria from replicating. The main difference between sterilization and disinfection is, that sterilization kills all microorganisms, while disinfection eliminates

Antibiotics are influential in the stopping of bacteria and other infections. The real question though is if they are more harmful then they are good? This essay will focus on whether or not antibiotics affect the human microbiome, how does the human microbiome respond to antibiotics and how does it respond when a person stops taking antibiotics. Firstly, antibiotics do affect the human microbiome very heavily. In today’s medical system antibiotics are the first option when trying to fight dangerous
