| prevalence and genomic analysis of infectious hypodermal and hematopoietic necrosis virus (ihhnv) in litopenaeus vannamei shrimp farmed in shanghai, china. | infectious hypodermal and hematopoietic necrosis virus (ihhnv) is prevalent among farmed shrimp and results in significant reductions in shrimp production. in order to gain a better understanding of the prevalence of ihhnv in the litopenaeus vannamei shrimp population of shanghai, china, samples were collected during two cultivation seasons and subjected to diagnostic pcr. the results of this study showed that 167 out of 200 shrimp were positive for ihhnv, indicating a high viral prevalence (83. ... | 2016 | 27568013 |
| aquimarina penaei sp. nov., isolated from intestinal tract contents of pacific white shrimp, penaeus vannamei. | a novel bacterial strain designated p3-1(t) was isolated from the intestinal tract contents of pacific white shrimp (penaeus vannamei) in zhangpu, fujian province, china. the isolate was found to be gram-negative, long rod shaped, oxidase- and catalase- positive. growth was observed at 1-7 % sea salt (w/v, optimum, 3 %), at ph 7.0-9.0 (optimum, ph 7.0) and at 10-37 °c (optimum, 28 °c). the isolate was capable of hydrolysing gelatin, casein, starch and dna but unable to degrade tween 20, 40, 80 a ... | 2014 | 25253586 |
