Sick patients coming in to the hospital can bring pathogens with them Shared caretakers and equipment can transmit microbes between patients Patients may be exposed to antiseptic chemicals O An ill person has weakened immune function MacBook Air DD F9 F8 吕0 000 F7 F6 F5 F4 F3 & #3 $ 8 4 このMicrobes possess many different strategies to help them cause disease called virulence factors. Explain how two virulence factors work. For each virulence factor state the name of the mechanism, explain how it works and what advantage it gives the organism that helps it cause disease.Below are a list of virulence factors/ strategies paired with an example of an organism that utilizes them. How do each of the following strategies contribute to the virulence of the pathogen? Strategy - Causes the host to produce more receptors (Organism - Rhinovirus) Strategy - Produces gas as a product of fermentation (Organism - Clostridium perfringens) Strategy - Produces a capsule (organism - Klebsiella pneumonia) Strategy - Ability to move between adjacent cells (organism - Cytomegalovirus) Strategy - Ability to use pilus as a motility structure (organism - Pseudomonas aerogenosa)
- Determine the chain of infection for the following scenarios and describe what you would do to break it. How could the disease have possibly been prevented? The Hunters Jeremy goes hunting with his friends. Luck was on his side today and he was able to shoot a doe. His friends were lucky too. Total they got 3 more deer to take home. Hours later Jeremy was home and processed the deer (skinning and gutting) so that he could freeze the meat for use over the next few months. A few months later, Jeremy ate his first patch of deer meat. Afterward he started experiencing stomach pains, diarrhea, discoloration on his ears and teeth. Jeremy’s family who also ate the deer experienced similar problems. Things are starting to add up. Jeremy gets a phone call from his friends (fellow hunting partners) and he describes his symptoms. His friend comments that he had similar issues when he ate his deer several months earlier. He said he never really thought anything of it because the…The success of a pathogen in invading an organisms depends on the number and the pathogens. O visibility O adhesiveness adherence O quality ofplease give me an answer that's not been posted yet. think about one of these organ system: cardiovascular, respiratory, lymphatics, integumentary. Within one of those systems, talk about the most troubling symptom a patient might have that would signal to you an infectious disease. So just one system and one symptom per person, I'm sure you will all come up with many different ones. For that symptom discuss why it is most troubling to you and how it might signify an infectious disease. You can also include examples of diseases that might fit with that symptom.
