2001年3月20日从越南芽庄的斑节对虾（Penaeus monodon）中分离到一种海洋真菌，命名为NJM 0131。根据其无性繁殖特征，鉴定其为Milfordensis，并对其生理特性进行了研究。虽然该分离物的最适生长温度为25 ℃-30 ℃，但该真菌生长的温度范围很宽（15 ℃-40 ℃）。H. milfordensis在50%~ 100%海水中生长良好，在含1.0%~ 5.0%NaCl和KCl的PYG培养基中生长较差。该菌生长的pH范围较宽（4.0-11.0），最适pH为7.0-9.0。人工感染试验表明，该菌株对三疣梭子蟹幼体也有致病性，但死亡率不高。这是越南首次报道由H.米尔福登西斯
A marine fungus was isolated from the black tiger prawn Penaeus monodon at Nha Trang, Vietnam, on March 20, 2001 and named isolate NJM 0131. The fungus was identified as Haliphthoros milfordensis from the characteristics of asexual reproduction, and its physiological characteristics were investigated. Although the optimum temperature for growth of the isolate was 25degree-30degreeC, the fungus grew at a wide range of temperatures (15degree-40degreeC). H. milfordensis grew well in 50%-100% seawater, but poorly in PYG agar containing 1.0%-5.0% NaCl and KCl. The fungus grew at a wide range of pH (4.0-11.0) with the optimum pH value of 7.0-9.0. The isolate also showed pathogenicity to swimming crab larvae (Portunus trituberculatus) by artificial infection, but mortality was not high. This is the first report of disease in the black tiger prawn P. monodon in Vietnam caused by H. milfordensis.
