Abstract

Insights

Sporobolomyces roseus, a yeast-like fungus, caused severe skin lesions in a Jagd Terrier. Treatment challenges highlight the need for further research into canine fungal infections.

Area of Science:

  • Veterinary Dermatology
  • Mycology
  • Infectious Diseases

Background:

  • Sporobolomyces spp. are environmental yeasts rarely implicated in human infections like dermatitis and meningitis.
  • In veterinary medicine, Sporobolomyces spp. have been documented only once, in a dog with granulomatous meningoencephalitis.

Purpose of the Study:

  • To report a case of dermatological lesions caused by Sporobolomyces roseus in a dog.
  • To discuss the diagnostic and therapeutic challenges associated with this fungal infection in veterinary medicine.

Main Methods:

  • A 3-year-old Jagd Terrier presented with crusted, erosive, and ulcerative skin lesions.
  • Skin histopathology revealed pyogranulomatous dermatitis.
  • Pan-fungal conventional polymerase chain reaction (PCR) and sequencing identified Sporobolomyces roseus.

Main Results:

  • The dog showed initial improvement with voriconazole and terbinafine but relapsed upon treatment discontinuation.
  • Subsequent antifungal treatments were ineffective, leading to euthanasia.
  • Sporobolomyces roseus was identified as the causative agent of the dermatological lesions.

Conclusions:

  • This case highlights Sporobolomyces roseus as a cause of canine dermatitis.
  • Treatment challenges and the need for prolonged antifungal therapy are emphasized.
  • Further investigation into Sporobolomyces infections in animals is warranted.

Bacterial Phylum Spirochaetes01:30

Bacterial Phylum Spirochaetes

Spirochetes, unique bacteria in the phylum Spirochaetes, are gram-negative, motile, tightly coiled, slender, and flexible. They inhabit aquatic sediments and animals, with some causing diseases like syphilis. Spirochetes are classified into eight genera based on habitat, pathogenicity, phylogeny, and characteristics.Their distinctive motility arises from endoflagella, located within the cell’s periplasm. These endoflagella anchor at the cell poles and extend along the cell length, encased by a...

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...

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...
Fungal Group Zygomycota01:29

Fungal Group Zygomycota

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...
Atypical Pneumonia01:14

Atypical Pneumonia

Atypical pneumonia, often caused by Mycoplasma pneumoniae, is a form of pulmonary infection that differs from the classical presentation of bacterial pneumonia in both its cause and clinical symptoms. Mycoplasma pneumoniae is a pleomorphic bacterium notable for its lack of a rigid cell wall. This structural characteristic imparts resistance to beta-lactam antibiotics and significantly influences the bacterium’s behavior within the human host.Other pathogens responsible for the disease include...
Staphylococcal Skin Infections01:29

Staphylococcal Skin Infections

Staphylococcus aureus is a Gram-positive coccus that resides harmlessly on the skin and mucous membranes of healthy individuals. When the skin barrier is breached, it can shift from a commensal to an opportunistic pathogen. This transition is facilitated by surface adhesins, such as clumping factor B and S. aureus surface protein G (SasG), which bind to structural proteins, including loricrin and cytokeratin, in the damaged epidermis. Protein A, another key factor, binds the Fc region of...
