The presence of pus necessarily suggests bacterial contamination caused by staphylococcus and streptococcus. Interaction of neutrophils with these bacteria represents the mechanism of formation of pus in the human body. The presence of these bacteria can be analyzed and questioned as follows: 1. Were the bacteria already present prior to the surgical procedure? 2. Was the material previously contaminated by bacteria? 3. Was there any failure in the aseptic procedure? 4. Was there lack of oral hygiene in the postoperative phase? If the pus is formed, staphylococcus and streptococcus are present.
