White spot syndrome virus (WSSV) and prevalence of disease resistance in a commercially cultured population of Penaeus monodon Fabricius, 1798 (Decapoda, Dendrobranchiata)

Abstract: White spot disease (WSD) caused by the white spot syndrome virus (WSSV) is the leading cause for huge economic destruction in the shrimp aquaculture industry. The present study investigates the prevalence of WSSV and disease-resistant shrimps among a commercially cultured population of Penaeus monodon Fabricius, 1798. Results suggest that WSSV prevalence among 32 culture ponds affected by various diseases was 58.2% cumulatively in 2009 and 2010. Real-time PCR yielded 1.46 x 108, 1.94 x 106 and 3.6 x 104 copies… Show more

“…In Bangladesh, it has been observed from field experience that some farmers in South-West region are able to obtain a reasonably good harvest despite the presence of WSSV infection characterized by severe white spot on carapace, while similar observations have also been reported from China (Lan et al 2002 ). These observations suggested the existence of possible disease resistant shrimp and genetic variants of WSSV (Chakrabarty et al 2014a , b ; Mallik et al 2016 ; Morse 1994 ). Genetic variants arisen due to mutations could be a probable reason behind molecular diagnostic failure mainly owing to inhibition of binding PCR primers; that might lead to false negative PCR results or non-specific PCR products which in return, limits the use of PCR based diagnostic kits (Mendoza-cano and Sanchez-paz 2013 ; Kwok et al 1990 ).…”
