• Caused by bacteria leptospires: long, thin, motile spirochetes maintained in the genital and urinary tract

• Characterized by Weil’s in 1886

• Also known as infectious jaundice

• Animals are the natural host

• The infection is often wrongly diagnosed due to the wide range of symptoms.

• Wrong diagnosis leads to potentially fatal infections of the kidney, liver, brain,

lung or heart

A Global Infection

Annual rates of leptospira infection

0.02 per 100,000 population in temperate climates 100 to 500 times increased rate in tropical climates

Associated with heavy rainfall or flooding

Leptospirosis Prevention

Vaccinate your pets to protect them and your family members against this disease

Avoid contact with animal urine or body fluids, particularly with any open wounds

Do not swallow, swim or walk in water that may contain animal urine

Wear protective clothing or footwear near soil or water that may be contaminated with

animal urine

Leptospirosis Course

2 days – 4 wks In 2nd week

Page 9: The resource for testing of Leptospirosis On site

Common Symptoms of Leptospirosis

• High fever • Headache • Chills • Muscle aches • Vomiting • Jaundice • Red eyes • Abdominal Pain • Diarrhea • Rash

Page 10: The resource for testing of Leptospirosis On site

Leptospirosis Complications If not diagnosed and treated

• Ards • Azotemia • Meningitis • Extreme fatigue • Hemorrhage• Hearing loss• Respiratory distress • Pulmonary hemorrhage • Hepatomegaly• Weil's disease (liver and renal failure)• Fatality rate is 1 to 5%! Hepatomegaly

Leptospirosis Treatment

A curable Infection!

• Can be treated with antibiotics such as Doxycycline or Penicillin

• Treatment is most effective when started promptly

people with symptoms suggestive of leptospirosis should contact a health care

provider for an on site rapid test

Current Leptospirosis Diagnostics• Epidemiologic history History of contact with stagnant contaminated water or rodents

• MAT as gold standard to detect antibodies limited to reference institutes, large panel of the leptospria are required to make the test reagent; Positive result 10–12 days after the first clinical symptoms and signs

• Urine, blood, CSF culture The median time for positive result is from 3 weeks to 3 months; Useless for diagnosis, but is commonly used in research.

• PCR Early, accurate diagnosis, but expensive and is commonly used in research

• Serology antibody test Positive results seen in 5-10 days after infection, commonly used

Leptospirosis - Final Message• Infectious disease caused by leptospires

• Transmitted to humans by direct exposure to urine or tissue of an infected animal.

• Typically progresses through two phases of nonspecific symptoms.

• Pets may also be at risk of contracting leptospirosis.

• Treated with antibiotics and it is rarely fatal if treated promptly.
