Summary
Trichophyton verrucosum, a fungal infection, can mimic bacterial cellulitis in humans, leading to misdiagnosis. Early identification and antifungal treatment are crucial for effective management of this zoophilic dermatophyte.
Area of Science:
- Dermatology
- Mycology
- Infectious Diseases
Background:
- Trichophyton verrucosum is a common zoophilic dermatophyte causing chronic skin infections.
- Its varied presentation can include inflammatory lesions and systemic symptoms like fever.
- Misdiagnosis as bacterial infections is frequent, delaying appropriate antifungal treatment.
Observation:
- A cattle farmer presented with extensive, treatment-resistant erythematous skin plaques.
- The patient's cows were concurrently being treated for ringworm.
- Symptoms mimicked bacterial cellulitis, leading to unsuccessful antibiotic therapy.
Findings:
- Skin biopsy confirmed fungal elements, and culture identified Trichophyton verrucosum.
- The patient's history of contact with infected livestock was a key diagnostic clue.
- Successful treatment was achieved with the antifungal medication itraconazole.
Implications:
- Highlights the importance of considering fungal infections in zoophilic dermatophytosis, especially in agricultural settings.
- Emphasizes the need for accurate diagnosis to avoid prolonged and ineffective antibiotic treatments.
- Underscores the efficacy of systemic antifungal therapy for extensive T. verrucosum infections.

01:08Cloning of Dolly the Sheep
The first successfully cloned mammal was Dolly, a sheep, born on 5th July 1996 at Roslin Institute, Scotland. The cloned sheep was named after the American singer Dolly Parton. Dolly lived for seven years and died of respiratory complications, which is speculated to be due to the actual age of her DNA. Because the DNA in cloned cells belongs to an older individual, the cloned individual’s life expectancy may be affected. Indeed, analysis of Dolly’s DNA revealed shorter telomeres than other...
02:20Milgram's Obedience to Authority
Obedience to authority is classically demonstrated in a more famous series of social psychology experiments performed by Stanley Milgram. He was a social psychology professor at Yale who was influenced by the trial of Adolf Eichmann, a Nazi war criminal. Eichmann’s defense for the atrocities he committed was that he was “just following orders.”
01:41Social Traps
Social traps are negative situations where people get caught in a direction or relationship that later proves to be unpleasant, with no easy way to back out of or avoid. The concept was orignally introduced by John Platt who applied psychology to Garrett Hardin's "Tragedy of the Commons", where in New England herd owners could let their cattle graze in the common ground. This situation seems like a good idea, but an individual could have an advantage. If they owned more cows, the larger...

The famous and controversial Stanford Prison Experiment, conducted by social psychologist Philip Zimbardo and his colleagues at Stanford University, demonstrated the power of social roles, social norms, and scripts.
01:12The Mammary Glands
The female breast is a hemispheric projection of variable size positioned anterior to the pectoralis major and serratus anterior muscles. A fascia layer composed of dense, irregular connective tissue connects it to these muscles.
Each breast features a pigmented projection known as the nipple, through which milk emerges via closely spaced openings of ducts, referred to as lactiferous ducts. Surrounding the nipple is a circular pigmented area of skin named the areola, which appears rough due to...

01:08Obedience
According to obedience research, we may harm others under the forceful pressures of an authority figure (Milgram, 1974). How about if the inappropriate orders were delivered with less force? The increasing interdependence between nurses and physicians compelled Hofling and his colleagues to explore nurses’ reactions to a potentially harmful medical request made by the perceived authority figure, the doctor (Hofling, Brotzman, Dalrymple, Graves, & Pierce, 1966). In this situation, obedience...
