    Temperature-influenced infection rates in the Chondrus crispus-Petersenia pollagaster pathosystem: A regression analysis
    Molina, F. I.; Hughes, G. C.; Craigie, J. S. (Springer, 1988-03)
    Cross-infection experiments were performed to determine the influence of temperature on infection rate in the Chondrus crispus Stackhouse-Petersenia pollagaster (Petersen) Sparrow pathosystem. C. crispus thalli were collected at Pubnico Harbor, Nova Scotia, Canada in the fall of 1981 to 1984. Infective zoospores were used to inoculate healthy thalli at five different temperatures. The highest infection rate was obtained at 20°C, while significantly lower rates were obtained at temperature extremes. The parasite's life cycle, consisting of infection of healthy thalli, endobiotic development, and release of zoospores, was completed in 48 to 72 h at 15° to 20°C.

    PCR test, quarantine for PHL shrimp vs viruses
    (Philippine Business Daily Mirror Publishing, Inc., 2021-06-27)
    Years before returning travelers were required to quarantine or get polymerase chain reaction (PCR) test for Covid-19, a research center is rigorously requiring the same for the country’s shrimp to ward off viruses and other pathogens that cause billions of dollars in losses to shrimp farms worldwide. These are being done in a birthing center for tiger shrimp at a seaside town in Iloilo, a news release from the Southeast Asian Fisheries Development Center Aquaculture Department (Seafdec/AQD) said. After releasing their eggs, the mother shrimp, called spawners, are tested for the white spot syndrome virus (WSSV), monodon baculovirus, infectious hypodermal and hematopoietic necrosis virus, yellow head virus, acute hepatopancreatic necrosis disease and the parasite Enterocytozoon hepatopenaei.
