The resource for testing of Leptospirosis
On site
• 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

2 days – 4 wks In 2nd week
Common Symptoms of Leptospirosis
• High fever • Headache • Chills • Muscle aches • Vomiting • Jaundice • Red eyes • Abdominal Pain • Diarrhea • Rash
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

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.
