| Abstract | In this study, we report a case of infective endocarditis caused by Lacticaseibacillus paracasei, which was diagnosed based on Gram stain findings at the time of positive blood culture, which suggested the genus Lactobacillus, which is known to be intrinsically resistant to vancomycin, and allowed early therapeutic intervention based on effective antimicrobial selection. The patient was a woman in her 80s. All two sets of blood cultures taken on admission were positive, and Gram stain showed Gram-positive bacilli with no spores, large size, linear shape, and chain formation. Blood cultures taken after antimicrobial therapy were negative. No complications of embolism were observed due to early initiation of effective antimicrobial agents. The treatment of severe infections, including those with positive blood cultures, is a race against time, and it is important to actively inform the clinician about the Gram stain findings. |
