Summary Introduction
Case summary:
Athlete’s foot is the fungal disease and it occurs in humans of all ages. It degrades skin keratin which causes itching in the infected area. In general, this fungal infection is transmitted through direct contact with the infected person’s things. Diabetic patients and people with impaired immune systems have a higher risk of athlete’s foot.

How does simply inhibiting the growth of a fungus eventually lead to curing a dermatophytic infection?
Many antibiotics used in modern medicine are compounds made by fungi that inhibit bacterial
protein synthesis. Describe the specific effect of the following antimicrobial drugs:
(i) Tetracycline
(ii) Puromycin
(iii) Alpha-Amanitin
anna is your client in a nursing home. She can walk but cannot take care of herself (needs help with ADL). She is overweight and has, among other things, large folds of skin on her stomach. You help her in the bath and notice that her skin folds and groin are very red. She also has scars under her breasts.
a) What could you suggest and do for Anna about this problem?
b) How could you tell if it was a fungal infection?
c) If Anna had a fungal infection in the skin folds, what could possibly be done for her?

- In 1985 a Paterson, N.J., Fire Department ambulance responded to a call reporting two people with severe itching, which they attributed to "voodoo beans" found in their beds. Soon after arriving the ambulance medical technicians developed the same symptoms. All four of the individuals went to the emergency room where they were found to have rashes on various parts of the body in addition to their itch. The admitting nurse, who put her arm around one patient, also developed a rash and itch on her arm. A policeman who went to the apartment the following day and a trash collector at the building also developed itching and received emergency room treatment. In all cases, symptoms disappeared in 1-2 hours. An industrial hygienist went to the site in complete protective gear to look for possible chemical contamination. Visual inspection and screens for ionized organic vapors were negative, but he retrieved a bean pod. The botanical specimen was sent to Rutgers University, where the plant was…arrow_forwardOur environment contains masses of microorganisms, many of which reside as commensal organisms on our body’s mucosal and epithelial surfaces without causing disease.

- How are Chlamydia and Mycoplasma (Section 16.9) similar?How are they different?arrow_forwardPart B: Antifungal agents are less selectively toxic than antibacterial agents meaning that they cause more damage to the host cells. Why is that the case?arrow_forwardDiseases caused by different types of pathogens have their own seasonality. That is, there is a higher frequency of bacterial and viral diseases in winter and a higher frequency of fungal and parasitological problems in summer. I explain winter, you explain summer. In winter, people are indoors with frequent touching of the same surfaces, breathing of the same air, as well as frequent contact. Bacterial diseases spread through touching of common surfaces while viral diseases also are spread through breathing in of infectious aerosols (someone’s sneeze, microbes in recycled air). Therefore the incidence of bacterial and viral diseases are greater during the winter. Why are fungal and protozoan diseases more important in the summer? (3 good reasons).arrow_forward
