Encephalitic listeriosis in two adult llamas (Lama glama): clinical presentations, lesions and immunofluorescence of Listeria monocytogenes in brainstem lesions.
Encephalitic listeriosis was diagnosed in 2 adult llamas. Both had a multifocal suppurative encephalitis with mixed lymphocytic and neutrophilic perivascular infiltrates. Listeria monocytogenes was cultured from the brain stem of 1 llama using cold enrichment techniques; the other llama was culture negative. Formalin-fixed and paraffin embedded sections of brainstem lesions from both affected animals were labeled with a fluorescein-conjugated, anti-L. monocytogenes antibody. Using this technique, intralesional L. monocytogenes were identified in both llamas.
