Concept explainers
To review:
The differences between infection and disease, pathogenicity and virulence, and LD50 and ID50.
Introduction:
Microorganisms cannot be seen with naked eyes but they are distributed everywhere in the surrounding such as soil, water, air, and also within other organisms. Certain microbes are adapted to grow in extreme conditions. Some of the microbial species have proved to be extremely beneficial to the humankind while others exhibit negative impact.
Explanation of Solution
The different forms of microbes such as bacteria, viruses,
1. Disease and infection:
2. Pathogenicity and virulence:
3. LD50 (lethal dose) and ID50 (infectious dose):

- Define the term virulence and how to determine it.arrow_forwardFoodborne pathogens often require the presence of a large number of microbes before an active infection results. These microbes would have a high Group of answer choices virulence. incubation period. mortality. median lethal dose (LD50). median infectious dose (ID50).arrow_forwardWhat is epidemiology? there are several ways pathogens can be transmitted including direct contact, indirect contact, via respiratory droplets, vehicle, and through a vector. Describe each mode IN DETAIL and give an example of a pathogen that can be transmitted each way.arrow_forward
- Describe the difference between the terms INFECTION and DISEASE. Starting with exposure to pathogens, describe IN DETAIL the steps involved in the infection process ( exposure, adherence, invasion and multiplication) as well as the disease process( Toxicity, invasiveness, tissue or system damage)arrow_forwardWhy have some diseases spread in our community, while others have vanished altogether? (connection to essential question and previous lesson)arrow_forwardDefine the term pathogen. Using MRSA, NOROVIRUS, ATHLETES FOOT and MALARIA as examples, identify the microorganisms (causal agent) involved in each disease. Provide some information on the microorganism for each disease e.g. structure Discuss 3 routes of entry that disease causing organisms use to enter the body.arrow_forward
- Model disease processes and explain virulencearrow_forwardNecator Americanus disease Epidemiological statistics: the current prevalence (at least in the US, worldwide preferred) of the disease, how many people are infected, how many people catch it every year, fatality rate (if any), etc. Explain briefly and list all references if you use any.arrow_forwardDescribe the factors that contribute to the emergence or re-emergence of disease.arrow_forward
- identify one type of pathogen or infectious agent. Describe ways to prevent the spread of the diseases this type of pathogen can cause and explain why these preventative measures are important.arrow_forwardDescribe the different ways a disease can be transmitted? What impact do we have as human that can support the control of transmission? What tactics, skills and/or techniques will you implement going forward to help control the transmission of microbes in your daily life?arrow_forwardName the most important control measure for preventing person-to-person transmission of a disease.arrow_forward
