Introduction to Microbes and Infectious Disease

Transcription

1 Name: Date: Introduction to Microbes and Infectious Disease Station 1) Pathogens Pathogens are capable of causing. Examples: Station 3) Discovery My name is Anton von Leeuwenhoek, and in I documented my discovery of. Pathogens release that make us sick; can lead to if le< untreated. What are opportunis>c pathogens?. Station 2) General Types of Pathogens Bacteria Single celled. The most common pathogen; though most bacteria is or highly pathogenic. Treated with. Fungi Fungi can be single celled or mul>cellular. Made up of cells (, ) Fungi is a necessary component of the earth cycle s; most fungi is. Infec>ous fungi is treated with. Before bacteria was readily understood, what did people think caused diseases, such as Syphilis?. Station 4) The Savior of Mothers Who was Ignaz Semmelweis?. What is childbed fever?. Why is Semmelweis known as the savior of mothers?. Station 5) Robert Koch s Experiments Summarize Koch s experiments by wri>ng either health or death in the text boxes Protozoan Parasites Single celled. Many need mul>ple throughout their life cycle (such as an insect or rodent ). Treated with agents. Viruses Viruses are made up of encapsulated and protein;. Not all viruses are harmful to humans. Can be treated using. Mice + Blood from healthy farm animal Mice + Blood from unhealthy/dead farm animal What did Koch s experiment prove?. Name one other accomplishment of Koch s:.

2 Introduction to Microbes and Infectious Disease Station 6) Aerobic vs. Anaerobic Aerobic Microorganisms that are aerobic are known as. Can to break down molecules for. Growth is to how much is in areas where oxygen is readily available. Aerobic is the leading cause of clinical infec>ons among pathogens. Anaerobic Cannot grow in oxygen; it is for them. Are not able to make as much as aerobes. Live in places where oxygen is Break down food without oxygen in a process called. anaerobes typically use to break down food, but can switch to mode if oxygen is not available. Station 7 Flagella The singular form of flagella is, and it means. Flagella can be found in the following types of organisms: Monotrichous Amphitrichous Lophotrichous Peritrichous Endotrichous What is the func>on of the flagella?. Station 8) Bacteria Bacteria are categorized into 3 general shapes: All bacteria are ( organisms that lack a nucleus). Station 9) Nonpathogenic Bacteria Plenty of bacteria are actually, in fact your body consists of more cells than human cells. Helpful bacteria are also known as. Station 10) Gram Positive & Gram Negative Gram posi>ve bacteria have a thick layer of that dyes a color. Gram bacteria do not have a thick layer of pep>doglycan, and therefore show up as a color when dyed. The dyes used to determine Gram posi>ve vs. Gram nega>ve are or. Why are Gram nega>ve bacteria more resistant against an>bio>cs than gram posi>ve bacteria?. Gram nega>ve bacteria contain an outer sugar coa>ng that can help the bacteria.

3 Station 11) Bacteria Shapes Shape Bacillus Coccus Spiral Introduction to Microbes and Infectious Disease Description Station 12) Looking at Bacteria- Label and sketch what you see under the microscopes in each circle below: Prefixes can specify the bacterial shape further: Diplo= Strepto= Staphylo= Based on this informa>on, draw a diplococci: Draw a diplobaccili: Draw a staphylococci: Station 13) Bacilli Bacteria shaped O<en >mes contain for movement Gram Can be or faculta>ve anaerobic Found virtually anywhere, including: Soil Extreme environments What are endospores?. Examples of illnesses caused by bacilli bacteria: Station 14) Cocci bacteria in shape Mostly Mostly ; some, a few are true. Examples of illnesses caused by cocci bacteria Gram Posi>ve Gram Nega>ve Teacher Ini>al x What is MRSA and why is it a problem?.

4 Station 15) Spiral Bacteria Gram Mostly Introduction to Microbes and Infectious Disease Examples of Spiral bacteria: Spirillum Spirochete Vibrio Station 16) Antibiotics An>bio>cs are used to treat infec>ons only. Examples of an>bio>cs: An>bio>cs can prevent further bacterial infec>on in one of two ways: 1) Prohibi>ng certain that bacteria need to build their. 2) Prohibi>ng certain enzymes that bacteria need to their. These an>bio>c methods prevent bacteria from growing and. What is penicillin?. Synthe>c deriva>ves of penicillin include and. What does MRSA stand for? Station 17) Pathogenic Protozoa Protozoans made up of single cells. Examples of diseases caused by infec>ous protozoans include: Malaria ea>ng Amoebic Chagas disease are used to treat protozoa infec>ons. These target that affect the of protozoans. Station 18) Monoxenous vs Heteroxenous Monoxenous= contact with. Example: water. Heteroxenous= Requires ; can include a vector such as and rodents. Examples: Malaria ( ). Station 19) Entoamoebas Most protozoans require to thrive. What are the symptoms of amoebic dysentery?. Are entoamoebas monoxenous or heteroxenous? Explain..

5 Station 20) Pathogenic Protozoa- Plasmodia Plasmodia cause, which is transmiged by. Symptoms of malaria: Headache Fever Pain Chills Dry Spleen Nausea When the mosquitoes bite their host, plasmodia are introduced into the bloodstream and develop in the. Eventually, they are released into the bloodstream and agack the. How many people are infected with malaria each year, approximately? Station 22) Pathogenic Fungi Only or can be pathogenic. are toxins produced by pathogenic fungi. Fungi like warm, moist places on the human body such as, the, feet,, and. Some molds produce, which can infect the if inhaled. Station 24) Airborne Fungal Infection Mold produces, which can become airborne. The two most common types of fungal lung infec>ons found in hospitals are and. Can a mosquito pass malaria on from one human to another?. Symptoms include, and. Typically fungal lung infec>ons are a secondary infec>on of someone who already has a immune system. Station 21) Pathogenic Protozoa: Chagas Disease Which type of protozoan causes Chagas disease? How is Chagas disease transmiged from kissing bugs?. How does Chagas disease affect the body?. An>rprotozoals used to treat Chagas disease target, structures found within the trypanosomes. Is Chagas disease caused by monoxenous or heteroxenous protozoa? (See Sta>on 18) Station 23) Fungal Infections of the Skin and Nails are fungi that can infect the skin. Fungal infec>ons can occur on the skin if the skin is - somehow; - If the host s system is compromised; - If the condi>ons are right ( ; ) (or a combina>on of these situa>ons)! Common fungal infec>ons include: Athlete s Candida ( ) itch Station 25) Candida Candida is an pathogen. Candida infec>ons can be found in the skin, lungs,,, intes>nes &.

6 Station 26) Viruses Viruses are the pathogen. Viruses are NOT made up of. Why might some argue that viruses are not living creatures?. An>virals (circle one) [target do not target] viruses; rather an>virals inhibit viral growth by preven>ng them from unpacking _. Viruses can be transmiged by them, them, transmiged, or from or bites. List 5 examples of viruses you ve heard of before: Station 30) HIV and AIDS AIDS stands for: _ HIV stands for: _ What is the source of HIV in humans?. HIV agacks the system and makes it very. Pa>ents are more suscep>ble to and. Symptoms: Systemic, weight loss,, mouth, esophageal sores, myalgia, liver and spleen, headache, rash,, vomi>ng. Station 27) Influenza The influenza virus is a highly contagious virus of the. If a dog has influenza, it is most likely type. Which type of influenza affects mostly children? The flu accounts for 250,000- deaths/year. The influenza virus tends to be ever changing ( ; ). The flu vaccine s effec>veness depends on how well it the flu viruses that are causing illness. The flu can lead to (poten>ally fatal) Station 28) Herpes Simplex Virus Those infected with HSV are typically because the herpes virus can remain for long periods of >me. During an outbreak, which symptoms may a person have? HSV- 1 causes and can be transmiged via. HSV- 2 causes and is transmiged. Station 29) Hepatitis Virus Hepa>>s viruses are responsible for disease, and is the number one cause of liver and Type of Hepa>>s A & E B, C, D Symptoms: How it s spread Station 31) Ebola The Ebola virus agacks the system and. It also agacks - cells, which leads to internal. How is Ebola spread? The original source of Ebola was most likely and other diseased animals. When and where was the most recent outbreak of Ebola?
