Molecular detection of pathogenic Leptospira from cattle in peri-urban areas of Addis Ababa, Ethiopia

October 2023

Leptospirosis is a bacterial, zoonotic disease caused by pathogenic Leptospira. Rodents are known to carry pathogenic Leptospira, but livestock are also important hosts. The disease is economically important in cattle, causing abortion, decreased fertility and decline in milk yield. Pathogenic Leptospira are shed in cattle urine and can survive in the environment. Only a few studies have been performed in Ethiopia to...
