Actinomyces species and Nocardia species are bacterial genera that have this morphology. Of the two, Actinomyces is most likely in cases of pyothorax in the cat.

An acid-fast stain (either Ziehl–Neelsen, or Kinyoun’s Cold Acid-Fast [an easy one to do in-house]) would differentiate the two species; Nocardia species are partially acid-fast, whilst Actinomyces are acid-fast negative.
