5 Animal Infections That Penicillin Can Help

Penicillin is an antibiotic that has long been used to treat different bacterial infections, and the medicine can be beneficial for both people and animals.

Penicillin is usually administered by injection when the antibiotic is given to animals.

If you have an animal that is ever diagnosed with any of these five infections, penicillin may be prescribed for treatment.

5 Animal Infections That Penicillin Can Help

Urinary Tract Infection

Bacterial infections can develop in the bladder, kidneys, and other parts of an animal’s urinary tract. These infections can and will result in urination problems, pain, and fever.

Penicillin is commonly prescribed to treat dogs and cats with urinary tract infections.

The antibiotic may prevent the infection from spreading to other parts of the body.

Bacterial Meningitis

Dogs and cats are often prone to this infection, which occurs when bacteria inflame the outer membranes along the brain and spinal cord.

Your pet may have this condition if you notice a decrease in appetite, vomiting, and fever.

Penicillin can often alleviate the inflammation to avoid additional complications that may threaten the life of your pet.

Bacterial Pneumonia

Sometimes referred to as shipping fever, bacterial pneumonia is usually caused by the Pasteurella multocida bacterial strain.

Cattle and sheep are especially prone to this infection. Penicillin injections can usually reduce symptoms or alleviate them entirely 36 to 48 hours after starting treatment.

Staph Aureus

Common among dairy cattle, staph aureus can affect the udders and skin and cause abscesses to form.

The infection can be transmitted from contaminated milking equipment and milkers’ hands that have bacteria on them.

The penicillin that’s produced by US Vet or another reputable manufacturer can often treat this condition successfully.

If you’re a dairy farmer and have any cows with this condition, you’ll definitely want to start antibiotic treatment right away to prevent milk production disruptions and further infections among your cattle.


This upper respiratory tract infection occurs in horses and often causes fever, nasal discharge, and breathing difficulties.

If lymph nodes in the neck enlarge from swelling, the upper airway could become blocked. This could result in a medical emergency.

Painful pus-filled abscesses may also form. Penicillin often works at treating this condition successfully.

Modern medicine has made it possible for people and animals to live better lives and penicillin has been proven to be one of the most reliable treatments for bacterial infections.

A veterinarian can examine your animal to determine if penicillin is a suitable solution for any conditions that may be diagnosed.
