Pediococcus pentosaceus SEPTIC ARTHRITIS OF KNEE: A CASE REPORT


ABSTRACT
A diabetic man with chronic liver disease developed septic arthritis of knee. The joint infection was caused by Gram positive cocci called Pediococcus pentosaceus.

INTRODUCTION
Pediococcus spp. are Gram positive aerobic cocci that belong to lactic acid bacteria, they are catalase-negative, non-spore forming (1). Although Pediococci appear to be closely related to streptococci by morphologic and physiologic criteria, but they are more closely related to lactobacilli (2). Among the Pediococcus spp. only P. acidilactici and P. pentosaceus have been isolated from clinical sources (3) and few reports blame them responsible for bacteremia (4) and septicemia (5). We reported a diabetic man with chronic liver disease who developed septic arthritis of knee caused by infection with Pediococcus pentosaceus.

Keywords: Pediococcus pentosaceus, Septic Arthritis, Chronic Liver Disease, Diabetes mellitus.
