    Insights

    Dermatophytes and keratinophilic fungi, primarily Microsporum canis, were found in 75% of cats and 36.9% of dogs. The mite Tyrophagus putrescentiae may aid fungal dispersal, suggesting acaricide use for prophylaxis.

    Area of Science:

    • Veterinary Mycology
    • Animal Dermatology
    • Environmental Microbiology

    Background:

    • Fungal infections, particularly dermatophytosis, are common in domestic animals.
    • Identifying causative agents and transmission routes is crucial for effective treatment and prevention.
    • The role of ectoparasites in the dissemination of fungal pathogens warrants investigation.

    Purpose of the Study:

    • To identify dermatophytes and keratinophilic fungi in cats and dogs.
    • To determine the prevalence of specific fungal species and genera.
    • To explore the potential role of the mite Tyrophagus putrescentiae in fungal transmission.

    Main Methods:

    • Fungal isolation from hair samples of cats and dogs over an 11-month period.
    • Identification of isolated dermatophytes and keratinophilic fungi.
    • Observation of mite infestation on fungal cultures.

    Main Results:

    • Dermatophytes and keratinophilic fungi were isolated from 75% of cats and 36.9% of dogs.
    • Microsporum canis was the most prevalent isolate in both species.
    • The mite Tyrophagus putrescentiae was frequently found on M. canis cultures, suggesting a role in fungal carriage.

    Conclusions:

    • Fungal infections are prevalent in cats and dogs, with M. canis being a significant pathogen.
    • The mite T. putrescentiae may act as a vector for fungal dispersal among animals.
    • Acaricide treatment could be a valuable adjunct to antifungal prophylaxis in animals.

    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...
    Overview of Fungi01:29

    Overview of Fungi

    Fungi are a diverse group of eukaryotes more closely related to animals than other eukaryotes. Fungal cell walls comprise chitin, a polysaccharide that provides structural strength, and glucans, which contribute to flexibility and integrity. Other polysaccharides, such as mannans and galactosans, may supplement or replace chitin in some fungi. These adaptations, along with their preference for acidic environments and tolerance for high osmotic pressure, enable fungi to thrive in various...

    Fungal Phylum Microsporidia

    Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...

    Fungal Phylum Ascomycota

    Phylum Ascomycota, a major division within the subkingdom Dikarya, comprises a diverse range of fungal species, including both unicellular yeasts and filamentous molds such as Aspergillus and Penicillium. These fungi thrive in a variety of habitats, from aquatic ecosystems to terrestrial environments, playing crucial ecological and economic roles.Morphology and ReproductionThe defining characteristic of Ascomycetes, commonly referred to as sac fungi, is the ascus—a sac-like structure that...

    Fungal Phylum Basidiomycota

    Basidiomycota is a diverse phylum of fungi that includes ecologically significant decomposers such as white rot fungi, symbionts like mycorrhizal fungi, plant pathogens such as rusts and smuts, and edible species like Agaricus bisporus (the common button mushroom). These fungi play crucial roles in nutrient cycling, symbiotic relationships, and even human health. Their defining feature is the basidium, a microscopic club-shaped structure responsible for producing basidiospores.Fruiting Bodies...

    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...
