[Dermophytes and guinea pigs : An underestimated danger?]
Summary
Pet shop guinea pigs frequently carry Trichophyton benhamiae, a fungus causing human infections, often without showing symptoms. Veterinarian checks for new pets are recommended to prevent transmission.
Area of Science:
- Veterinary Dermatology
- Mycology
- Zoonotic Diseases
Background:
- Increasing human infections with Trichophyton benhamiae, primarily in children, have been noted.
- Pet guinea pigs are a significant source of transmission for this zoophilic dermatophyte.
- The prevalence of T. benhamiae in pet shop guinea pigs remains largely uninvestigated.
Purpose of the Study:
- To determine the frequency of T. benhamiae in guinea pigs from pet shops in Berlin.
- To assess T. benhamiae carriage in both symptomatic and asymptomatic guinea pigs.
Main Methods:
- Sampling of 59 guinea pigs from 15 pet shops using toothbrush and swab methods.
- Detection of T. benhamiae via polymerase chain reaction (PCR) and fungal culture.
Main Results:
- T. benhamiae was detected in over 90% of sampled guinea pigs.
- Only 9% of infected guinea pigs displayed visible tinea symptoms.
- Most infected guinea pigs were asymptomatic carriers.
Conclusions:
- Pet shop guinea pigs represent a high-risk reservoir for T. benhamiae.
- Transmission to humans can occur from asymptomatic carriers.
- Veterinary examination of newly acquired guinea pigs is advised.

From Water to Land
Epiphytes, Parasites, and Carnivores
Plants often form mutualistic relationships with soil-dwelling fungi or bacteria to enhance their roots’ nutrient uptake ability. Root-colonizing fungi (e.g., mycorrhizae) increase a plant’s root surface area, which promotes nutrient absorption. While root-colonizing, nitrogen-fixing bacteria (e.g., rhizobia) convert atmospheric nitrogen (N2) into ammonia (NH3), making nitrogen available to plants for various biological functions. For example, nitrogen is essential for the biosynthesis of the...
Pigmentation
The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

Skin Diseases and Disorders
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.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Diversity of Protists II
Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...
The Skin Microbiota
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...
