It has been found that coagulase positive staphylococci also produce the enzyme phosphatase (Barber and Kuper, 1951).Whereas the coagulase test must be applied to individual colonies, the phosphatase reaction provides a less time-consuming method of examining large numbers of colonies. Following incubation at 37°C for 24-48 hours in anaerobic conditions, the “bow-tie” zone of enhanced hemolysis pointing towards Streptococcus agalactiae is seen. His symptoms began three days prior and included left-sided upper neck and lower jaw pain and odynophagia.
