IL10 and infection: Significantly higher IL-10 levels in dogs with current infection with intracellular pathogens from the Anaplasmataceae family, confirmed by PCR-positive results compared with PCR-negative dogs, suggested that the production of the IL-10 in infected dogs can be stimulated by infected cells, monocytes, and neutrophils by the pathogens, but can also be as a defense immune response of the host.
