Pathogenicity
Infection and Transmission
The infections are generated by the pathogenic organisms present in the environment. They maintain the capacity to invade a host body and establish colonies. A disease caused by such infectious agents is called a communicable disease or transmissible disease. These diseases spread through diverse means including blood, food, water, air, or vectors.
What are some mechanisms by which pathogenic bacteria cause diseases? Why is this knowledge important?

- In terms of microbial pathogenicity, molecular Koch's postulates are a set of experimental criteria that show: A microbe is the aetiological agent of a disease A gene encodes a product that contributes to disease A gene encodes a product that contributes to immunity to a disease A mutation does not contribute to diseaseAn infectious disease is a disease that is caused when a pathogen is passed from one organism to another. The nonliving pathogen is the a) Parasites b) Bacteria c) Virus d) Protozoa Please I need a surely answer and a quicker responseHow does each of the differences between prokaryotes and eukaryotes influence bacterial infection and treatment?
- Describe how to recognize the presence of mutant, antiobiotic resistant bacteria. Where do they come from?Which statement among A-D is false regarding bacterial toxins? A) O Hemolysıns are cell membrane disrupters that can rupture red blood cells. B) O Second mesengar pathway disrupters like cholera toxin produces a debilitating respiratory condition of the lungs. C) O Shiga toxin, tetanus toxin, and hemolysins are all types of exotoxins. D) O Superantigens elicit a hyperactive response by the immune system and can lead to shock. E) O None are false, A-D are all true statements.John Smith is a pig farmer. For the past five years, Smith has been adding vitamins and low doses of antibiotics to his pig food; he says that these supplements enhance the growth of the pigs. Within the past year, however, several of his pigs died from infections of common bacteria, which failed to respond to large doses of antibiotics. Can you explain the increased rate of mortality due to infection in Smith’s pigs? What advice might you offer Smith to prevent this problem in the future?
- How are disease bacteria transmitted?What is the best explanation for why a bacteriostatic treatment might be chosen over a bacteriocidal treatment? Bacteriostatic treatments will eliminate all bacteria while bacteriocidal treatments will only eliminate a portion of the bacteria. Bacteriostatic treatments typically have lower toxicity to the host when compared to bacteriocidal treatments. Bacteriostatic treatments will prevent all bacterial growth, while bacteriocidal treatments will permit some bacterial growth. Bacteriostatic treatments are typically more costly than bacteriocidal treatments.In 1928, British bacteriologist Alexander Fleming made an accidental discovery. He noticed that a fungus had contaminated one of the agar plates he had streaked with a bacterial species to be studied. The fungus prevented the bacteria from growing in the immediate area surrounding the fungus. Upon further investigation, Fleming found that the fungus produced a substance that was the agent responsible for killing the bacteria. He called this substance penicillin. Given this information, which statement best explains why Fleming's discovery is relevant to the general public today? O Fleming's attention to detail diverted his efforts to investigate bacteria and likely robbed humanity of important discoveries that he would have otherwise made. Fleming's sloppiness in the lab serves as a reminder to all researchers that sterile technique is critical to preventing unwanted fungal growth on bacterial plates. Fleming's discovery enabled the development of chemical substances as antibiotics to…
