(a)
To discuss:
The condition from which the patient is suffering also determines the likely causative agent of this condition.
Case summary:
A farmer who works on a piece of machinery gets injured by a sharp blade covered in mud slices through his upper arm. The farmer tries to control the bleeding and immediately seeks medical care. After three days, his arm becomes swollen and painful and fever develops. After removing the bandages, he observes that the wound has become blackened and bloody fluid leaking out of it. Microscopic analysis of fluid shows the presence of gram-positive bacilli.
(b).
To explain:
The process by which the patient contracted this pathogenic microbe and also determines the virulence factors that contributed to the pathogenesis at the wound site.

Microbiology: A Systems Approach
- Consumer products including bandages, cotton balls, diapers, and contact lens solutions are routinely irradiated. There is no opposition to these products in the marketplace. Given this, why are irradiated foods not more accepted when they can prevent illness from E. coli and other pathogens?arrow_forwardDonna suddenly developed a sore throat accompanied by a fever of 103°F. When over-the-counter medication was ineffective, Donna sought the advice of her doctor. He took a throat culture and, anticipating that it might be a bacterial infection, he began her on a 10-day regime of antibiotics. Why is it important that the doctor confirms this is a bacterial infection, before prescribing antibiotics? Would the doctor prescribe antibiotics if this was a viral infection?arrow_forwardJosie developed a poison ivy rash after a camping trip. Her doctor prescribed a cortisone ointment to relieve the inflammation. Afew weeks later, Josie scraped her elbow, which became inflamed.Because she had some of the cortisone ointment left over, sheapplied it to the scrape. Was the ointment an effective treatmentfor the poison ivy? Was the ointment an appropriate treatment forthe scrape?arrow_forward
- A patient presents with symptoms of a heart attack, and it is noted that she also has a fever. Her husband suggests that she must have an infection. What would you tell him?arrow_forwardThe material which is the result of the battle between macrophages and invading microbes is called ___. It is a yellow or greenish semi-liquid.arrow_forwardA common characteristic of a site of infection, such as a pimple on the skin, is pus. What is responsible for the white color of pus?arrow_forward
- The man pictured in Figure 4.17 wears skin ornaments applied by piercing. Among other functions, the skin is a barrier to potentially dangerous bacteria, and some people object to extensive body piercing on the grounds that it opens the door to infections. Explain why you do or dont agree with this objection. Figure 4.17 This young man has chosen to undergo multiple body piercings.arrow_forwardDifferentiate between droplet vehicle transmission and airborne transmission. Many people find that they become ill with a cold after traveling by airplane. The air circulation systems of commercial aircraft use HEPA filters that should remove any infectious agents that pass through them. What are the possible reasons for increased incidence of colds after flights? (Answer in 1000 words)arrow_forward5. You observe a blood agar plate and see a clear/transparent area where the bacteria has been inoculated. With this information what are some possible outcomes if someone was infected with this type of bacteria? Please explain.arrow_forward
- Candida Albicans may cause minor infections in healthy people,but causes dangerous infections in immunocompromisedpatients. Why?arrow_forwardYour child has had a moderate fever for 2 days. On the third day, you take her to the pediatrician. After an examination, blood is drawn and a CBC with diff is performed. How does this information aid the pediatrician in determining whether the cause of the infection is viral or bacterial?arrow_forwardMalaria disease is characterized by cycles of symptoms that last 4-8 hours and have 3 stages; a 15-to-60 minute cold stage when you shiver and feel very cold, a 2-6 hour hot stage when your fever may reach as high as 41oC and finally, a 2-4 hour sweating stage during which your fever drops rapidly. These cycles are called paroxysms. Explain why they typically happen in malaria patients based on the pathogen life cyclearrow_forward
