Leptospirosis

Here, a number of rope-like leptospira bacteria are shown through an electron microscope. Infection in humans can cause fever, severe headaches, chills, muscle aches, vomiting, jaundice, abdominal pain and diarrhoea. However, some people show no symptoms at all. Meat workers, dairy farmers and veterinarians are the people most at risk. Stock carrying the disease should be identified, isolated and vaccinated.
