Black quarter (BQ) is an important infectious bacterial disease causing wide spread damage among the livestock especially cattle, buffaloes and sheep. It is also reported in a variety of animals, including fish and whales, but is of utmost importance in cattle and sheep. Pigs are very rarely affected; man and equidae are completely resistant (Sterne, 1975). True Black quarter (BQ) is caused by Clostridium chauvoei (Cl. chauvoei) sometimes referred to as Cl. feseri (Batta et al., 1995), but mixed infections resulting from Cl. chauvoei and Cl. septicum are not uncommon, albeit, the significance of Cl. septicum is still debated (Barnes et al., 1975).
