Abstract

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, Streptococcus agalactiae, 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.

Abstract

Introduction: Stenotrophomonas maltophilia is an opportunistic bacterium and has rarely been reported as a cause of infection in the cornea. Ocular infection due to Stenotrophomonas maltophilia is an opportunistic infection followed by instability of the ocular surface. Casalita et al. (2020), in their research at Cipto Mangunkusumo Hospital, Jakarta, Indonesia found two cases of infected corneal ulcers due to Stenotrophomonas maltophilia. Case description: A 57-year-old man came to the eye clinic with pain in the left eye and blurred vision. The patient was diagnosed with severe corneal ulcer and regularly came for the treatment. The patient felt that his eye suddenly got worse with visual acuity only to his hand movement. Corneal ulcer swab procedure is performed when the patient firstly visit the clinic. Samples are sent to the microbiology laboratory for culture examination. Culture results obtained were coagulase negative Staphylococcus and Stenotrophomonas maltophilia. Conclusion: Stenotrophomonas maltophilia has several virulence factors, including resistance to various antibiotics, making it difficult to treat.

Abstract

Introduction: The normal vaginal flora consists of aerobic and anaerobic bacteria; Lactobacillus sp. is the main microorganism in the vagina. In bacterial vaginosis, there is a decrease in Lactobacillus sp. and an increase in pathogenic bacteria. Direct gram staining of vaginal fluid is the standard microbiological method for diagnosing bacterial vaginosis. Gram staining allows us to distinguish between gram-positive and gram-negative bacteria based on differential staining with crystal violet iodine complex and safranin. This study aimed to evaluate and compare the gram stain results between the dermatovenereology clinic and microbiology laboratories. Case description: Direct gram staining of vaginal or cervical swabs was carried out on women aged 19 years, women aged 29 years, and women aged 40 years. The gram staining was carried out at the dermatovenereology clinic and microbiology laboratory with different results between the two locations. Conclusion: It is important to evaluate the process of taking vaginal fluid samples, making smears/slides, and gram staining so that the quality of the examination results is maintained
