Rapid test detects NHP in penaeid shrimp
A rapid lateral-flow immunoassay using monoclonal antibody combinations can identify necrotizing hepatopancreatitis (NHP) infection in less than 15 minutes.

Genetic diversity of HPV parvovirus
Hepatopancreatic parvovirus is linked to growth retardation in shrimp. In a study, the genomic sequences of HPV from Madagascar and Tanzania were compared to those from Australia, Thailand and Korea.

Feed-related melamine risk minimal to shrimp, humans
Although histological studies of shrimp that consumed feed with the suspect ingredients found crystals of salts of melamine in antennal glands, the crystals did not affect the shrimp.

White tail disease in shrimp mimics infectious myonecrosis
White tail disease in shrimp can result from various conditions. Infectious Myonecrosis is a significant disease of white shrimp in both Latin America and Asia.

Kona-line SPF shrimp, Vibrio penaeicida candidates for bacterial challenge model
Juvenile SPF Kona-line shrimp were injected with V. penaeicida, causing significant disease, but certain bacterial concentrations allow survival long enough for additional testing.

Strain of reference shrimp aids researchers, farmers
Kona line reference shrimp contribute to research by providing test stocks that are consistently and predictably susceptible to Taura Syndrome Virus.

TSV challenges advance selective breeding in Pacific white shrimp
Results of ongoing studies demonstrate that selective breeding for both resistance to Taura Syndrome Virus (TSV) and fast growth in shrimp is achievable.

Diagnostic profile of Belize Taura Syndrome Virus
Shrimp farming in Belize, Central America, was hard hit by Taura Syndrome Virus (TSV, now known as TSV serotype A) in 1996 and a re-emergence in 2002.

Dietary modifications for desert shrimp farming
Since the first pioneer shrimp farm was established in the area in 1997, desert shrimp farming in Arizona, USA, has expanded rapidly.

Sea birds pose threat as vectors of penaeid shrimp pathogens
Sea birds can spread viral, bacterial, fungal and protozoan diseases to shrimp farms, so future farm designs should take their presence into account.

Necrotizing hepatopancreatitis: Diagnosis, distribution in shrimp
Necrotizing hepatopancreatitis has become one of the most important bacterial diseases affecting shrimp farming in the Americas.

Selectively bred shrimp survive varied TSV exposure
A 14-day study evaluated mortalities related to TSV exposure, as broodstock resistant to an “old” strain succumbed to a “new” Belize strain of the virus.
