Introduction: Diabetic foot infection is a complication that often occurs in people with diabetes mellitus. Staphylococcus
aureus is the most common microorganism found in diabetic foot infections. In addition, coagulase-negative staphylococci,
Enterococcus faecalis, Streptococcusagalactiae, and Pseudomonas aeruginosa can also be demonstrated. Diabetic foot infection
treatment usually takes a long time which may increasing the risk of antibiotic resistance. This article will present a unique
and interesting case about Streptococcus agalactiae resistant to β-lactam infection.
Case description: A 56-year-old man presented with a long history of diabetes mellitus but had not taken anti-diabetic
drugs and had no history of previous use of antibiotics. Since 2016 his right foot had a recurring wound that he routinely
treated. Microbiology culture of the wound swab obtained three bacteria namely Streptococcus agalactiae, Proteus mirabilis
and Klebsiella pneumoniae which is resistant to β-lactam antibiotics.
Conclusion: The identification of Group B Streptococcus bacteria (Streptococcus agalactiae) which are resistant to β-lactam
antibiotics (penicillin, third and fourth generation cephalosporins) which were found in this case, reminds all medical
personnel to be more careful and prudent in the rational use of antibiotics.
