    In humans, Nocardia species have the potential to cause localised or disseminated infection (Cooper and others 2014). This genus has previously been detected in wild ungulates (Vemireddi and others 2007, Domenis and others 2009) but not in wild boar (Sus scrofa). Although hundreds of ungulates are hunted in the Iberian Peninsula annually, no case of nocardiosis from wild boar has been reported.

    Seven samples of lymph nodes with granulomatous lymphadenitis, with gross visible tuberculosis-like lesions but negative to mycobacteria in culture and PCR, from seven wild boar were analysed. Gram-stained smears revealed Gram-positive short filaments, coccoid forms, and branching rods in all samples. In the Ziehl-Neelsen stain, the s
