First report of Cryptosporidium spp. oocysts in oysters (Crassostrea rhizophorae) and cockles (Tivela mactroides) in Brazil [PDF]

Journal of Water and Health, 2008
The consumption of oysters and cockles, which are usually eaten raw or lightly-cooked, can cause outbreaks of human diseases, especially if these shellfish are harvested from polluted areas. In Brazil data about the occurrence of pathogens, like hepatitis A virus, in shellfish have been reported but research on natural contamination for pathogenic ...

A qPCR-Based Survey of Haplosporidium nelsoni and Perkinsus spp. in the Eastern Oyster, Crassostrea virginica in Maine, USA [PDF]

Pathogens, 2020
Eastern oyster (Crassostrea virginica) aquaculture is increasingly playing a significant role in the state of Maine’s (USA) coastal economy. Here, we conducted a qPCR-based survey for Haplosporidium nelsoni, Perkinsus marinus, and Perkinsus chesapeaki in C. virginica (n = 1440) from six Maine sites during the summer–fall of 2016 and 2017.

Development of a sensitive polymerase chain reaction (PCR) and digoxigenin (DIG)-labeled in situ hybridization (ISH) for the detection of Vibrio bacteria in the Pacific oyster Crassostrea gigas

Aquaculture Reports, 2022
Vibrio bacteria are one of the greatest threats to aquaculture, with Vibrio-associated mass mortality events occurring in all life stages worldwide. Vibrio aestuarianus is particularly problematic in Pacific oyster Crassostrea gigas cultures.
