case_images: Gram-positive coccobacilli were isolated from 3 bottles (1 pair of FA-Plus and FN-Plus bottles and another FN-Plus bottle) within 48 hours of incubation at 35 C with 7% CO2 (Figure 1).

case_images: Weissella confusa through matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS, VITEK MS system, bioMerieux Inc.), with a coincidence rate of 99.9% (Figure 4). We conducted in vitro drug susceptibility experiments using both the disk diffusion method (using sheep blood Mueller-Hinton agar plates) and the microbroth dilution method.
