Understanding Fungal and Bacterial Infections in Pets

What are Fungal Infections?

Fungal infections affecting pets are the result of fungi invading the skin These infections usually develop in an opportunistic fashion when some animals become weak against the immune system. Fungi are available in soil, decaying matter, and even infected animals.

  • Ringworm (Dermatophytosis)- An infection that affects the skin even between humans and pets. The lesions formed are circular and usually itchy.

What are Bacterial Infections?

Infections in pets could arise from harmful bacteria entering into the body through wounds, from contaminated food or water, or even as a result of bad hygiene. Sure, some bacteria can be present naturally in the bodies of pets; such bacteria are usually called opportunistic bacteria. Opportunistic bacteria can create a condition of illness when they grow in excess or enter into the body from outside.

Some common bacterial infections in veterinary animals are as follows:

  • Leptospirosis Highly infectious and can infect even humans.

  • Pyoderma - Mostly skin infections like sores and redness.

Key Differences Between Fungal and Bacterial Infections

Skin, ears, nails, respiratory system, and sometimes internal organs

Any body part, including skin, GI tract, urinary tract, and respiratory system

  • Breathlessness (infected pneumonia)

Causes and Risk Factors

Some factors which make pets susceptible to fungal and bacterial infections: 

Fungal Infection Dangerous Factors

  • High humidity causing moist skin folds (yeast infections)

  • Infection through contact of pet with infected soil or infected animal

  • Weak immune system leading to rapid contraction of infection from other sources

  • Open wounds or scratches that have not been treated

  • Poor hygiene (dirty bedding, contaminated drinking water)

  • Stress or disease that may cause reduced immunity
