A new bacterial strain, designated SHRIMP(T), isolated from the haemolymph of the Pacific white shrimp, Penaeus vannamei, was serologically distinct from other spiroplasmas. Cells of this strain were helical in form and variable in length. Examination by electron microscopy revealed wall-less cells delineated by a single cytoplasmic membrane. The organisms grew well in M1D media supplemented with 2 % NaCl. Strain SHRIMP(T) grew at temperatures of 20-37 degrees C, with optimum growth occurring at 28 degrees C. The strain catabolized glucose and hydrolysed arginine, but did not hydrolyse urea. The G+C content of the DNA was 29 +/-1 mol%. Strain SHRIMP(T) (=ATCC BAA-1082T=CAIM 1252T) is designated the type strain of a novel species, Spiroplasma penaei sp. nov., which represents a new subgroup (I-9) of the group I spiroplasmas.
从南美白对虾凡纳滨对虾血淋巴中分离出的一株新细菌，命名为SHRIMP(T)，在血清学上与其他螺旋体不同。该菌株的细胞呈螺旋状，长度可变。电子显微镜检查显示，无壁细胞由单一的细胞质膜界定。该菌在添加2%氯化钠的M1D培养基中生长良好。SHRIMP(T)菌株在20-37摄氏度的温度下生长，最适生长温度为28摄氏度。该菌株能分解葡萄糖并水解精氨酸，但不水解尿素。DNA的G+C含量为29±1 mol%。SHRIMP(T)菌株(=ATCC BAA-1082T=CAIM 1252T)被指定为一个新物种——对虾螺旋体新种的模式菌株，它代表了I组螺旋体中的一个新亚组(I-9)。
