Current status of L. infantum infection in stray cats in the Madrid region (Spain): implications for the recent outbreak of human leishmaniosis?
Parasites & Vectors 2014, 7:112 (24 March 2014)
The results of this survey suggest a stable L. infantum infection among the stray cats of the Madrid area; the disease is uncommon and no clinical cases have been reported to date. The detection of other zoonotic parasites such as T. gondii and T. cati in stray cats indicates a need to adopt strict control measures in this population.
