The Difference Between Your Skin and That of Your Pets
While humans and other species share some of the same genetic information, new research found that humans are unique among mammals when it comes to the types and diversity of microorganisms on our skin.
The skin microbiomes of humans, dogs, cats, and horses differ in composition, diversity, and function due to variations in skin physiology, environmental exposure, and lifestyle. Here’s a basic comparison:
1. Human Skin Microbiome
Diversity: Moderate to high diversity, with a balance of bacterial, fungal, and viral species.
Dominant Microbes: Bacteria; Staphylococcus epidermidis, Propionibacterium acnes (now Cutibacterium), Corynebacterium species. Fungi; Malassezia species.
Characteristics:
- The skin is relatively dry compared to animals, with variations in moisture and pH depending on the body area (e.g., scalp vs. forearm).
- Human skin tends to have lower pH (acidic) than animals, aiding in microbial regulation.
- Environmental Impact: Constantly exposed to diverse environments, which affects microbiome composition.
2. Dog Skin Microbiome
Diversity: Lower diversity than humans but with significant variation by breed, age, and environment.
Dominant Microbes: Bacteria; Staphylococcus pseudintermedius, Corynebacterium species, Pseudomonas species.
Characteristics:
- Dogs have oilier skin than humans, with a higher pH (neutral to slightly alkaline).
- Their skin microbiome is influenced by frequent outdoor exposure and contact with soil, water, and other animals.
- Skin folds (in some breeds) create unique microenvironments for specific microbial communities.
3. Cat Skin Microbiome
Diversity: Moderate diversity; influenced by grooming habits and exposure.
Dominant Microbes: Bacteria; Pasteurella, Micrococcus, and Staphylococcus felis.
Characteristics:
- Cats have relatively dry skin with a slightly acidic to neutral pH.
- Extensive grooming behavior can alter and regulate the skin microbiome.
- Less exposure to environmental microbes than dogs, leading to a more stable microbiome.
4. Horse Skin Microbiome
Diversity: High diversity, driven by extensive environmental exposure.
Dominant Microbes: Bacteria; Corynebacterium, Staphylococcus equorum, Bacillus species. Fungi; Aspergillus and Penicillium species.
Characteristics:
- Horses have thicker skin with significant sweat and sebaceous gland activity.
- The skin microbiome is influenced by constant exposure to soil, plants, and other outdoor elements.
- Skin tends to have a slightly higher pH compared to humans and cats.
Key Differences:
pH: Human skin is more acidic, whereas animal skin (dogs, cats, horses) tends to be neutral to slightly alkaline.
Exposure: Animals, especially horses and dogs, have greater environmental exposure, influencing their microbial diversity.
Grooming: Cats and horses naturally regulate their skin microbiomes through grooming or sweat production, while humans rely on hygiene products.
Dominant Microbes: Each species has unique dominant bacterial and fungal groups tailored to its skin’s environment and physiology.
These differences underscore the need for species-specific approaches when considering skincare or treatments that affect the microbiome. At Sturtevant’s Veterinary Remedies, we have been studying the various microbiomes extensively over several decades to better understand how to develop the best treatments for both two-legged and four legged patients.
Our expertise in this area has resulted in the creation of broad-spectrum treatments which are safe and effective for everyday use that help to balance and strengthen the respective patient microbiomes while addressing many of the most common skin irritations and accompanying discomfort.
