白虾瞎眼病,又叫烂眼病,是目前白对虾养殖过程中新见的一种疾病。此病的传播速度较快,病虾大多在1周内陆续死亡,死亡率一般在10％-30％左右。病情严重的可高达80％以上。因此切实地做好疾病的预防工作至关重要。 经初步研究,该病的病原体系非01群霍乱弧菌,该菌为革兰氏阴性弧状杆菌,具动力,氧化酶、过氧化氢酶阳性。该菌喜高温、低盐。生长温度范围是15-45℃,最适生长温度是30-42℃,在淡水及海水中都可生长。可发育的食盐浓度范围是0-5％,最适范围0.5％-2.0％;pH值在5-10范围内都能生长,
White shrimp blind, also known as bad eye disease, is currently a new disease in white shrimp farming process. The spread of the disease faster, most of the sick shrimp died one week in succession, the mortality rate is generally 10% -30%. Serious illness can be as high as 80% or more. Therefore, it is very important to do a good job in disease prevention. After a preliminary study, the pathogen of the disease is non-01 group Vibrio cholerae, the bacterium is Gram-negative bacillus, with motility, oxidase, catalase positive. The bacteria like high temperature, low salt. Growth temperature range is 15-45 ℃, the optimum growth temperature is 30-42 ℃, can grow in fresh water and seawater. Potable salt concentration range is 0-5%, the optimum range of 0.5% -2.0%; pH range of 5-10 can grow,
