Of Space Germs and Cassini's Big Finish.

For the past twenty years, a whopping 1.2 billion kilometres away from Earth, a little unmanned spacecraft called the Cassini-Huygens has been orbiting Saturn and faithfully collecting… 1,226 more words



Haplosporidian species (phylum Haplosporidia Caullery & Mesnil, 1899) are a small group of four genera of sometimes pathogenic protozoan parasites usually with uninucleated spores. They are widely distributed in marine and freshwater invertebrates, although their status in Africa, much of Eurasia and Central and South America, is largely unknown. 183 more words


The oyster immunity

Oysters, the common name for a number of different bivalve molluscs, are the worldwide aquaculture species and also play vital roles in the function of ecosystem. 176 more words


Diagnosis and Control of Diseases of Fish and Shellfish

There has been a continual expansion in aquaculture, such that total production is fast approaching that of wild-caught fisheries. Yet the expansion is marred by continued problems of disease. 170 more words


Mass selection for survival and resistance to OsHV-1 infection in Crassostrea gigas spat in field conditions: response to selection after four generations

The ostreid herpesvirus 1 (OsHV-1) is one of the major pathogens affecting the Pacific oyster Crassostrea gigas, and numerous mortality outbreaks have been observed worldwide. 351 more words


Growing blacklegged tick populations = growing incidence of tick-borne illnesses (including Lyme disease)

This spring brought with it predictions of higher tick populations this summer, especially in the Northeast … along with heightened concern of contracting Lyme disease. Lyme disease is caused by the bacterium… 342 more words

Environmental Change

Seasonal variation of transcriptomic and biochemical parameters of cockles (Cerastoderma edule) related to their infection by trematode parasites

Bivalve populations are controlled by several biotic and abiotic factors. Parasitism is among the biotic factors but is often neglected. In the present study, we focused on the transcriptomic and biochemical responses of… 178 more words
