What Is Yeast Infection?
Yeast infections are caused by certain types of bacteria called yeasts. These yeasts cause the symptoms of various diseases such as skin infections, ear infections, urinary tract infection, respiratory disease etc. Yeast infection can affect any part of your body including eyes, ears or nose. It may even occur at the site where no wound exists. There are two main types of yeast infections: primary and secondary (also known as tertiary). Primary yeast infections are usually caused by Staphylococcus aureus (strep throat) and Streptococcus pyogenes (pyoderma gangrenosum). Secondary infections are caused by other species of bacteria such as Candida albicans, Escherichia coli, Klebsiella pneumoniae, Serratia marcescens and others.
Primary Yeast Infections In Dogs
Strep Throat – Strep throat is a common condition that affects both humans and animals. It causes inflammation of the throat and tonsils, which leads to pain in swallowing.
If left untreated, it can lead to difficulty breathing and death. The most common symptom of strep throat is fever, headache, cough, runny nose and sore throat. If your dog is suffering this, then it has a throat infection caused by strep bacteria. The symptoms would be similar to those of a human with strep throat.
Pyoderma Gangrenosum – Pyoderma gangrenosum is another skin infection caused by Staphylococcus bacteria. It mainly affects people with weakened immune systems such as people with diabetes and cancer patients.
However, the condition can also affect dogs. The condition typically causes ulcers to develop on the skin. The ulcers may look like open sores or red patches with a blue border (the technical term is an “eschar”). Ulcers usually form on nostrils, armpits, genitals and perineum.
Secondary Yeast Infections In Dogs
Dogs can acquire yeast infections by coming into direct contact with infected bodily fluids from other animals such as blood, saliva and vaginal secretions. The most common types of dog yeast infection are listed below:
Infected pores (Boils)
These are painful red lumps that form under the skin. They’re usually caused by staphylococcus bacteria or pyoderma (bacterial infection of the skin).
Dogs of any age and gender can get boils, though they’re more common in males 10 months or older.
There are various types of fungal skin infections, such as yeast infections, ringworm and dermatophytosis. Unlike bacterial infection, these don’t cause pain.
The most common symptom is itching. Dermatophytosis is an infection caused by a type of fungus called Trichophyton or Microsporum gypseum. It is contagious to humans and animals.
