| estimation of prevalence of white spot syndrome virus (wssv) by polymerase chain reaction in penaeus monodon postlarvae at time of stocking in shrimp farms of karnataka, india: a population-based study. | white spot disease (wsd) is at present the most serious viral disease affecting cultivated shrimp species globally. the causative agent, white spot syndrome virus (wssv), is extremely virulent, has a wide host range and can also be transmitted from broodstock to their offspring. the shrimp postlarvae (pl) act as asymptomatic, latent carriers of the virus, and stocking of wssv-infected pl has been reported as a risk factor for wsd outbreaks in culture ponds. however, there is no population-based ... | 2002 | 12113310 |
| usefulness of dead shrimp specimens in studying the epidemiology of white spot syndrome virus (wssv) and chronic bacterial infection. | this paper describes the utility of dead shrimp samples in epidemiological investigations of the white spot syndrome virus (wssv) and chronic bacterial infections. a longitudinal observational study was undertaken in shrimp farms in kundapur, karnataka, india, from september 1999 to april 2000 to identify risk factors associated with outbreaks of white spot disease (wsd) in cultured penaeus monodon. as a part of the larger study, farmers were trained to collect and preserve dead and moribund shr ... | 2002 | 12152899 |
| relationship between white spot syndrome virus and indicators of quality in penaeus monodon postlarvae in karnataka, india. | white spot disease (wsd) is a viral disease of shrimp caused by white spot syndrome virus (wssv). stocking wssv-infected seed has been implicated as a major risk factor for outbreaks of wsd. in addition, the quality of postlarvae batches has been proposed as a predictor for good crops. this paper describes the relationship between indicators of quality and wssv in postlarvae (pl) of penaeus monodon from karnataka, india, over the period september 1999 to january 2000. three outcome variables wer ... | 2003 | 12747635 |
| evaluation of an immunodot test to manage white spot syndrome virus (wssv) during cultivation of the giant tiger shrimp penaeus monodon. | a monoclonal antibody-based immunodot test was compared to a polymerase chain reaction (pcr) assay for managing white spot syndrome virus (wssv) on shrimp farms at kundapur and kumta situated in udupi and uttar kannada districts, respectively, of karnataka on the west coast of india. of 12 grow-out farms in kundapur, 6 (f1 to f6) yielded shrimp samples that were negative for wssv by both immunodot test and 1-step pcr from stocking to successful harvest. samples from the other 6 farms (f7 to f12) ... | 2008 | 18500033 |
| assessment of wssv prevalence and distribution of disease-resistant shrimp among the wild population of penaeus monodon along the west coast of india. | shrimp aquaculture is threatened by many diseases, among which white spot disease (wsd) caused by white spot syndrome virus (wssv) is the leading one. information related to the geographical distribution and seasonal prevalence of wsd is necessary to obtain a clear understanding of the disease biology in shrimp. identification of wsd-resistant individual shrimp with dna markers is also an important technique to develop better wsd-free shrimp health management. the present study aim is to estimat ... | 2014 | 24681359 |
