These two isolates presented typical characteristics of Streptococcus iniae with gram-positive cocci in chains, catalase negative and beta-hemolytic, growth under 10℃ and non-growth up 45 ℃, hydrolyzation of esculin and arginine, Voges-Proskauer, urease, and hippurate tests negative, fermentation of glucose, salicin, sucrose and starch, non-fermentation of arabinose, inulin, lactose, melibiose, raffinose and sorbitol.

实验结果表明，两菌株具有典型的海豚链球菌特性：在显微镜下为球形细胞，呈长短不一的链状排列，革兰氏染色阳性：在血琼脂平板上显示β溶血；1O℃生长，45℃不生长；接触酶阴性；水解七叶苷、精氨酸，VP试验、脲酶和马脲酸试验阴性；发酵葡萄糖、水杨苷、蔗糖和淀粉，不发酵阿拉伯糖、菊糖、乳糖、蜜二糖、棉子糖和山梨醇等。

Nov.. The main symptoms of the bacterial disease on Vigna angularis were canker of stalk.The strains were straight or curved rods; polar flagellum one; Gram-negative; could infect Vigna angularis、 Glycine max、 Vigna radata、 Vigna umbellate、 Phaseolus vulgaris、 Pisum sativum、 Pisum sativum var.humlie; oxidase negative; nitrate reduction negative; 5% glucose agar mucilage positive; esculin hydrolysis positive; starch negative; milk hydrolysis positive; H_2S positive; acid from L-arabinose, D-mannose, D-galactose, cellobiose, trehalose and fructose; 5%NaCl positive; G+Cmol%-69%.

红小豆溃疡病主要症状为茎部溃疡；各菌株菌体均杆状；极生鞭毛1根；革兰氏染色阴性；人工接种能侵染多种豆科植物；好氧；氧化酶阴性；硝酸盐反应阴性；5％葡萄糖营养琼脂黏液生长阳性；七叶灵水解阳性；淀粉水解阴性；牛奶分解产碱；产生硫化氢；能从阿拉伯糖等产酸；最大耐盐量为5％；G+Cmol％为69％等特征，根据《手册》9th ed相关部分，确定该病由野油菜黄单胞菌苜蓿致病变种Xanthomonas campestris pv.alfalfae(Riker，Jones et Davis 1935)Dye 19781引起。
