White leg shrimp, Penaeus vannamei , were collected on a monthly basis from grow‐out ponds located at Tamil Nadu and Andhra Pradesh states along the east coast of India for screening of viral and other pathogens. Totally 240 shrimp samples randomly collected from 92 farms were screened for white spot syndrome virus (WSSV), infectious hypodermal and haematopoietic necrosis virus (IHHNV), infectious myonecrosis virus (IMNV) and...

White spot syndrome virus ( WSSV )‐infected shrimp samples collected from grow‐out ponds located at Nellore, Andhra Pradesh, India, showed WSSV negative and positive by PCR using primer sets specific to ORF 119 and VP 28 gene of WSSV , respectively. This indicated the deletion of genetic fragments in the genome of WSSV . The WSSV isolate along with lab strain of WSSV was subjected to next‐generation sequencing. The sequence an...

Whiteleg shrimp, Litopenaeus vannamei, with clinical sign of muscle opaqueness with reddish colour at the distal abdominal segments were observed in farms located in West Bengal State, India. The mortality of shrimp in all disease outbreak ponds ranged from 20% to 50%, and mortality increased gradually. The RT ‐ PCR assay of these samples using primer sets specific to infectious myonecrosis virus ( IMNV ) revealed its presence...
