Fungal Phylum Microsporidia01:28

Fungal Phylum Microsporidia

374
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 Group Zygomycota01:29

Fungal Group Zygomycota

944
Zygomycota, previously classified as a distinct fungal group, are primarily terrestrial, saprophytic molds that play a crucial role as decomposers. Recent phylogenetic studies have revealed that these fungi are now divided into two major clades — Mucoromycota, which includes many symbiotic species, and Zoopagomycota, which primarily consists of parasitic and pathogenic fungi. These groups exhibit distinct ecological roles and reproductive strategies while sharing key structural and...

Skin Diseases and Disorders

5.1K
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...

Skin Cancer01:30

Skin Cancer

5.7K
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.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Reticular Dermis01:15

Reticular Dermis

4.4K
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...

Papillary Dermis01:11

Papillary Dermis

5.3K
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...

    This summary is machine-generated.

    Non-dermatophytic fungi were found in over 10% of dogs with skin lesions. These fungi, including Alternaria and Penicillium, were more common in warm, humid climates.

    Area of Science:

    • Veterinary Mycology
    • Canine Dermatology

    Background:

    • Cutaneous lesions in dogs can have various etiologies.
    • Dermatophytes are common fungal causes of skin disease in dogs.
    • The role of non-dermatophytic fungi in canine skin infections is less understood.

    Purpose of the Study:

    • To investigate the prevalence of non-dermatophytic fungi in dogs with skin lesions.
    • To identify specific non-dermatophytic fungal species associated with canine cutaneous conditions.
    • To explore potential environmental factors influencing the incidence of these infections.

    Main Methods:

    • Screening of 205 dogs with cutaneous lesions for fungal presence.
    • Isolation and identification of non-dermatophytic fungi from skin samples.
    • Correlation of fungal isolation with climate data.

    Main Results:

    • Twenty-two dogs (10.8%) yielded non-dermatophytic fungi.
    • Commonly isolated fungi included Alternaria sp. (2.9%), Penicillium sp. (2.4%), and Aspergillus fumigatus (2.0%).
    • Higher incidence of these fungal infections was observed in warm and humid climates.

    Conclusions:

    • Non-dermatophytic fungi are potential causative agents of skin lesions in dogs.
    • Climate, particularly warmth and humidity, may play a role in the prevalence of these infections.
    • Further research is warranted to elucidate the pathogenicity of these fungi in canine dermatological conditions.
