SUMMARY: Bovine actinomycosis exudate was studied to determine the chemical composition and mineral phase(s) of the so-called ‘sulphur granules’. The major constituents, CaO and PO, accounted for 86-89% of the ashed granules. The granules also contained Na, K, Mg (as oxides) and Cl which added up to 10-14%. Although the X-ray diffraction patterns indicated only poorly formed apatite; the infrared spectrum could be interpreted as arising from poorly crystallized apatite and/or a partially dehydrated or hydrolysed octacalcium phosphate either or both mixed with anhydrous dicalcium phosphate. The formation of pyrophosphate (44·5%) in the ignited granules indicated the presence of considerable acid phosphate in the original material.
