Leptospirosis is caused by a
bacteria which is spread through the excreta, secretions,
blood and urine of infected
animals. Raccoons, possums and other wild animals are typical
carriers of this bacteria. Symptoms can vary widely, with some
animals completely asymptomatic. When symptoms do develop,
they can include fever, vomiting, abdominal pain, diarrhea,
loss of appetite, severe weakness, depression, stiffness, or
muscle pain. There is the threat of human contraction of this
bacteria from infected animals, so vaccination is extremely
important. Dogs exposed to wet or marshy areas are often times
at higher risk for infection. Vaccines do exist, lasting
typically 6 months. Therefore, many veterinarians vaccinate against Leptospirosis
twice per year.
