A screening was conducted with 26 plants collected in the Brazilian southeast region, to identify plant extracts with antibacterial properties against Aeromonas hydrophila, Bacillus subtilis, Pseudomonas aeruginosa and Staphylococcus aureus. Initially, the agar diffusion method was employed. Then, those extracts presenting activity were submitted to a broth microdilution assay to determine the minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC). It was observed that 13 of the tested extracts showed antibacterial activity. The best results were obtained with those from Lantana lilacina and Phyllanthus tenellus.
对在巴西东南部地区采集的26种植物进行了筛选，以鉴定对嗜水气单胞菌、枯草芽孢杆菌、铜绿假单胞菌和金黄色葡萄球菌具有抗菌特性的植物提取物。最初采用琼脂扩散法。然后，将具有活性的提取物进行肉汤微量稀释试验，以确定最低抑菌浓度（MIC）和最低杀菌浓度（MBC）。观察到13种受试提取物具有抗菌活性。从马缨丹和千根癀中提取的提取物效果最佳。
