The pathogenic bacterial spirochetes of the Leptospiragenus are responsible for the infectious disease called leptospirosis. Both humans and animals can be infected and it is one of the most common infectious diseases of animals that can be transmitted naturally to humans. About 9 in every 10 people affected will experience mild flu-like symptoms. These include myalgia (muscle pain), chills, and headaches in the early stages. More severe presentations of the disease include internal hemorrhaging and multiple organ failure, which is life-threatening and is referred to as Weil’s disease.
Scientists have designed a single-dose universal vaccine that could protect against the many forms of leptospirosis bacteria, according to a study published today in eLife.
