Human Disease Leptospirosis Identified in New Species, the Banded Mongoose, in Africa

May 14, 2013 — The newest public health threat in Africa, scientists have found, is coming from a previously unknown source: the banded mongoose.

Leptospirosis, the disease is called. And the banded mongoose carries it.

Leptospirosis is the world's most common illness transmitted to humans by animals. It's a two-phase disease that begins with flu-like symptoms. If untreated, it can cause meningitis, liver damage, pulmonary hemorrhage, renal failure and death.

"The problem in Botswana and much of Africa is that leptospirosis may remain unidentified in animal populations but contribute to human disease, possibly misdiagnosed as other diseases such as malaria," said disease ecologist Kathleen Alexander of Virginia Tech.

With a grant from the National Science Foundation's (NSF) Coupled Natural and Human Systems Program, Alexander and colleagues found that the banded mongoose in Botswana is infected with Leptospira interrogans, the pathogen that causes leptospirosis.
