An outbreak of poisoning by Lantana camara occurred in cattle when a herd sought refuge in a Eucalyptus forest heavily infested by this plant. The animals showed apathy, elevated serum activities of hepatic enzymes, severe photosensitivity, jaundice, hepatomegaly and nephrosis. After a clinical manifestation period of 2-15 days, 74 out of 170 heifers died.

- Acute leptospirosis is a rare but serious disease in sheep that can lead to severe symptoms like jaundice, kidney damage, and liver inflammation, often diagnosed based on indirect evidence.
- Two outbreaks in Uruguay during September-October 2017 resulted in the deaths of 9 lambs each on two farms after heavy rains and flooding.
- The bacteria responsible, Leptospira interrogans serogroup Pomona serovar Kennewicki, was confirmed in both flocks, highlighting the potential for sheep to transmit leptospirosis to humans and other animals, warranting further research.
Article Synopsis
- Leptospirosis, caused by diverse spirochete bacteria called Leptospira, is a neglected disease affecting both animals and humans, with limited data on its serovars in South America, particularly Uruguay.
- A 3-year study isolated and characterized 40 strains of Leptospira from infected cattle, identifying five serovars, including L. interrogans and L. borgpetersenii.
- The findings revealed that about 20% of cattle are shedding pathogenic Leptospira, posing a public health threat, and highlighted the need for improved diagnostics and understanding of the disease's epidemiology in the region.
