title: The evaluation of bacteriology in perianal abscesses of 81 adult patients.
abstract: OBJECTIVE
  Treatment of perianal abscesses requires prompt surgical drainage and antimicrobial therapy. However, we should encourage the selective use of antimicrobial agents on a case-by-case basis, especially because there is no evidence that uncomplicated perianal abscesses can be safely treated only with drainage. For this reason, it is important to identify the causative organisms; therefore, we accessed the microbiological analysis of these patients.
  
  
  METHODS
  In this study, 81 consecutive adult patients with perianal abscesses, who presented at a university hospital in Diyarbakir from January 2004 to December 2006, were included. Clinical and laboratory data, and results of microbiological analysis were recorded.
  
  
  RESULTS
  All specimens, except seven, yielded bacterial growth. Escherichia coli, Bacteriodes spp., coagulase-negative Staphylococci, and Staphylococcus aureus were the most common isolated organisms.
  
  
  CONCLUSIONS
  In contrast to other investigators, this study demonstrated that aerobic organisms are the predominant isolates in these infections.
