Study analyzes samples of microsporidia-infected shrimp in Madagascar, Mozambique and Saudi Arabia and with clinical signs of cotton shrimp disease.
Authors examined the histological features from shrimp infected with the emerging microsporidian parasite Enterocytozoon hepatopenaei (EHP). A PCR assay method was used to detected in hepatopancreatic tissue, feces and water sampled from infected shrimp tanks, and in some samples of
In analyzing the plasmid sequence from the whole genome sequences of AHPND V. parahaemolyticus (V.p) isolates, researchers identified a clear geographical variation within the plasmid, and developed PCR methods to characterize AHPND V.p isolates as either Mexico-type or Southeast Asia-type.
A laboratory study at the University of Arizona examined the effects of tilapia to control EMS and mortality in Pacific white shrimp.in controlling AHPN.
Studies by the University of Arizona Aquaculture Pathology Laboratory identified the causative agent for AHPNS as a unique strain of Vibrio parahaemolyticus bacteria that can produce toxins responsible for the primary pathology in affected shrimp.
Since Taura syndrome virus was in the Americas when yellow head virus become pandemic in Asia, it is possible TSV prevented shrimp in the Western Hemisphere from infection by materials from Asia containing YHV. To test this idea, the authors
To determine origins of White Spot Syndrome Virus and Taura Syndrome Virus in Saudi Arabia, authors performed genotyping studies and found a new genotype in each of the isolates collected.
Early Mortality Syndrome is a new disease that has been detected at shrimp farms in Asia. It appears within 30 days of stocking and causes symptoms that include lethargy; soft, darkened shells and mottling of the carapace.
An in situ hybridization procedure can be used to diagnose blue crabs from Chesapeake Bay infected with a reovirus.
