Summary
Pet-related fungal infections, or dermatomycoses, can be challenging to diagnose. Polymerase chain reaction (PCR) quickly identified Arthroderma benhamiae from a patient and his guinea pig, enabling prompt antifungal treatment.
Area of Science:
- Mycology
- Dermatology
- Veterinary Medicine
Background:
- Dermatomycoses transmitted from animals present diagnostic challenges.
- Inflammatory presentations can mimic bacterial infections.
Observation:
- A 24-year-old man had inflammatory facial lesions.
- Initial bacterial pyoderma diagnosis was made due to negative fungal cultures.
- Lesions were on his cheeks and chin.
Findings:
- Polymerase chain reaction (PCR) confirmed Arthroderma benhamiae in the patient and his guinea pig.
- Arthroderma benhamiae is a zoophilic dermatophyte causing inflammatory tinea.
- This fungus is associated with guinea pig transmission.
Implications:
- PCR offers rapid and simple diagnosis of Arthroderma benhamiae.
- Timely diagnosis facilitates prompt initiation of antifungal therapy.
- Accurate identification of zoophilic dermatophytes is crucial for effective treatment.

01:27The Skin Microbiota
135
The human skin serves as a complex ecosystem inhabited by a diverse community of microorganisms, including bacteria, fungi, and viruses. This microbiome plays a critical role in maintaining skin health and defending against pathogenic invaders. The composition of microbial communities varies significantly across different regions of the body, influenced primarily by the local levels of moisture and sebum.Regional Variation in Skin MicrobiotaCutibacterium acnes predominantly colonizes sebaceous...

Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen...

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.

01:15Reticular Dermis
4.6K
The papillary and reticular dermis are the two layers of the dermis. They are made of connective tissue with fibers of collagen extending from one to the other, making the border between the two somewhat indistinct. The dermal papillae extending into the epidermis belong to the papillary layer, whereas the dense collagen fiber bundles below belong to the reticular layer.
Reticular Layer
Underlying the papillary layer is the much thicker reticular layer, composed of dense, irregular connective...

5.2K
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.

01:16Accessory Structures of the Skin: Hair and Hair Follicles
5.2K
Hair and hair follicles are integral components of the integumentary system. Hair is a filamentous structure composed mainly of a protein called keratin. It is found on the surface of the skin throughout the body, except for areas such as the palms of the hands and soles of the feet.
Hair is a keratinous filament growing out of the epidermis. It is primarily made of dead, keratinized cells. Hair strands originate at the epidermal penetration called the hair follicle. The hair shaft is the part...
