Acute Oak Decline (AOD) is an oak disease that was first described in the United Kingdom. From the time the first symptoms appear, the disease can kill trees even within 6 years. One of the factors causing this disease is the action of the pathogenic bacteria Brenneria goodwinii, Rahnella victoriana and Gibbsiella quercinecans. In recent years, a deterioration in the condition of oak stands has been observed throughout Slovakia. These trees show exudates characteristic of AOD, which may indicate the presence of pathogenic bacteria. Samples of such symptomatic exudates from tree trunks were collected and analysed on 20 different plots in central and western Slovakia. Using real-time PCR, the presence of Brenneria goodwinii and Gibbsiella quercinecans was confirmed in ten and three stands, respectively. This report is the first information about the observation of these bacteria in weakened stands of Quercus robur in Slovakia.

急性橡树衰退（AOD）是一种橡树病害，最早在英国被描述。从出现第一个症状时起，这种疾病甚至可以在 6 年内杀死树木。造成这种疾病的因素之一是病原菌古德温布伦氏菌、维多利亚雷氏菌和槲寄生吉布氏菌的作用。近年来，斯洛伐克各地的橡树林状况都在恶化。这些树木表现出 AOD 特征的分泌物，这可能表明存在致病细菌。在斯洛伐克中部和西部的 20 个不同的地块上收集并分析了来自树干的此类症状性分泌物样本。使用实时 PCR，分别在 10 个和 3 个林中确认了古德文布伦氏菌 (Brenneria Goodwinii)和槲寄生吉布氏菌 (Gibbsiella quercinecans)的存在。这份报告是关于在斯洛伐克栎树弱化林中观察到这些细菌的第一份信息。
