Comparative genomics inferred two distinct populations of piscine pathogenic Streptococcus agalactiae, serotype Ia ST7 and serotype III ST283, in Thailand and Vietnam

Abstract The genomes of Streptococcus agalactiae (group B streptococcus; GBS) collected from diseased fish in Thailand and Vietnam over a nine-year period (2008–2016) were sequenced and compared (n = 21). Based on capsular serotype and multilocus sequence typing (MLST), GBS isolates are divided into 2 groups comprised of … Continue reading

A validated semi-nested PCR for rapid detection of scale drop disease virus (SDDV) in Asian sea bass (Lates calcarifer)

Abstract Scale drop diseases virus (SDDV), a newly characterized virus of farmed Asian sea bass (Lates calcarifer), has been reported in several countries in Southeast Asia. However, no fully validated detection method is publicly available for disease diagnosis and surveillance. Here, we described … Continue reading

Natural occurrence of edwardsiellosis caused by Edwardsiella ictaluri in farmed hybrid red tilapia (Oreochromis sp.) in Southeast Asia

Abstract Infections caused by Edwardsiella ictaluri bacteria have mainly affected the catfish aquaculture industry in Asia and America, while few reports reveal E. ictaluri-associated mortality in non-catfish species. Here, we report a natural occurrence of E. ictaluri in hybrid red … Continue reading
