A novel monoclonal Perkinsus chesapeaki in vitro isolate from an Australian cockle, Anadara trapezia

A monoclonal Perkinsus chesapeaki isolate was established from 1 of 10 infected Australian Anadara trapezia cockles. Morphological features were similar to those of described P. chesapeaki isolates, and also included a unique vermiform schizont cell-type. Perkinsus olseni-specific PCR primers amplified DNAs from all 10 cockles. Perkinsus chesapeaki-specific primers also amplified DNAs from 4/10 cockles, including … Continue reading A novel monoclonal Perkinsus chesapeaki in vitro isolate from an Australian cockle, Anadara trapezia

Australia develops genetic research against deadly oyster virus

A genetic improvement program to breed oysters genetically predisposed to resist Pacific oyster mortality syndrome (POMS) -- a disease that is harmless to humans but so lethal to oysters that it can kill more than 90% of a crop of millions of animals within days -- is being developed in Australia. (...) (By Undercurrent News May 04, … Continue reading Australia develops genetic research against deadly oyster virus

Detection of ostreid herpesvirus 1 microvariant DNA in aquatic invertebrate species, sediment and other samples collected from the Georges River estuary, New South Wales, Australia

Ostreid herpesvirus 1 microvariants (OsHV-1) present a serious threat to the Australian Crassostrea gigas industry. Of great concern is the propensity for mortality due to the virus recurring each season in farmed oysters. However, the source of the virus in recurrent outbreaks remains unclear. Reference strain ostreid herpesvirus 1 (OsHV-1 ref) and other related variants … Continue reading Detection of ostreid herpesvirus 1 microvariant DNA in aquatic invertebrate species, sediment and other samples collected from the Georges River estuary, New South Wales, Australia

POMS not a case of if, but when for South Australian oyster industry

Bruce Zippel is also an oyster grower at Smoky Bay on the far west coast of South Australia, and said the state had learnt a lot since POMS was found in Tasmania earlier this year. South Australia has so far remained POMS-free. Mr Zippel is urging South Australian growers to continue supporting genetic selection programs … Continue reading POMS not a case of if, but when for South Australian oyster industry
