Summary
A rare bacterial dermatitis case in a spotted seal (Phoca largha) was diagnosed. This study offers a diagnostic and treatment approach for bacterial skin infections in pinnipeds.
Area of Science:
- Veterinary Dermatology
- Marine Mammal Medicine
- Infectious Diseases
Background:
- Cutaneous infections are significant in pinnipeds, with diverse etiologies.
- Specific agents like fungi, morbillivirus, and mycobacteria can induce granulomatous inflammation.
Observation:
- A captive spotted seal presented with chronic dermatitis.
- Diagnostic investigations included histopathology, microbial culture, special staining, and PCR.
Findings:
- The dermatitis was a rare pyogranulomatous case caused by Enterococcus faecalis (E. faecalis).
- Antibiotic susceptibility testing guided treatment for this specific bacterial infection.
Implications:
- This case highlights the importance of thorough diagnostics for unusual pinniped skin conditions.
- The study provides a valuable framework for diagnosing and managing bacterial dermatitis in pinnipeds.

A sebaceous gland is a type of oil gland found almost all over the skin ( except palms and soles) and helps lubricate and waterproof the skin and hair. Most sebaceous glands are associated with hair follicles. They generate and excrete sebum, a mixture of lipids, onto the skin surface, thereby naturally lubricating the dry and dead layer of keratinized cells of the stratum corneum, keeping it pliable.
These glands that produce the oils on the skin and hair are holocrine glands. The mature...

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...
