Isolation, genetic characterization, and virulence profiling of different species recovered from moribund hybrid catfish ( spp.).

Background And Aim: The high diversity of spp. results in various pathogenicity levels. This group of bacteria causes a serious disease named motile septicemia (MAS) in catfish ( spp.

A Global Survey of Hypervirulent Aeromonas hydrophila (vAh) Identified vAh Strains in the Lower Mekong River Basin and Diverse Opportunistic Pathogens from Farmed Fish and Other Environmental Sources.

Hypervirulent Aeromonas hydrophila (vAh) has emerged as the etiologic agent of epidemic outbreaks of motile septicemia (MAS) in high-density aquaculture of farmed carp in China and catfish in the United States, which has caused millions of tons of lost fish. We conducted a global survey to better understand the evolution, geographical distribution, and phylogeny of vAh. isolates were isolated from fish that showed clinical symptoms of MAS, and pure cultures were screened for the ability to utilize -inositol as the sole carbon source.

Prevalence, Antibiotics Resistance and Plasmid Profiling of spp. Isolated from Cultured Shrimp in Peninsular Malaysia.

is the most common bacterium associated with diseases in crustaceans. Outbreaks of vibriosis pose a serious threat to shrimp production. Therefore, antibiotics are commonly used as preventative and therapeutic measures.

Effect of an Oral Bivalent Vaccine on Immune Response and Immune Gene Profiling in Vaccinated Red Tilapia ( spp.) during Infections with and .

Streptococcosis and aeromonasis inflicted by Streptococcus iniae and Aeromonas hydrophila, respectively, have affected tilapia industries worldwide. In this study, we investigated antibody responses and explored the mechanisms of protection rendered by an oral bivalent vaccine in red tilapia following challenges with S. iniae and A.

Draft genome sequence of -inositol utilizing 1P11S3 isolated from striped catfish ( in a local fish farm in Malaysia.

A hypervirulent pathotype of (vAh) is responsible for Motile Septicemia (MAS) and causes mass mortalities among farmed carp and catfish species in the USA and China. One unique phenotype for vAh among other strains is the ability to utilize inositol as a sole carbon source. While screening for isolates from diseased fish that can grow using inositol as a sole carbon source, 1P11S3 was isolated from the spleen of striped catfish ( displaying clinical MAS symptoms from a freshwater farm in Malaysia.

Comparative Pathogenicity of spp. in Cultured Red Hybrid Tilapia ().

The genus has been recognised as an important pathogenic species in aquaculture that causes motile septicaemia (MAS) or less severe, chronic infections. This study compares the pathogenicity of the different spp. that were previously isolated from freshwater fish with signs of MAS.

Antibiotic susceptibility and pathogenicity of isolated from red hybrid tilapia (×) in Malaysia.

Background And Aim: is a major cause of bacterial infections affecting a wide range of warm water fishes worldwide. In Malaysia, isolations from diseased fishes were previously reported; however, with limited information. The present study investigates the antibiotic susceptibility and pathogenicity of isolated from farmed red hybrid tilapia ( spp.
