Haplosporidium nelsoni is a pathogen of oysters that originally caused oyster populations to experience high mortality rates in the 1950s, [1] and still is quite prevalent today. The disease caused by H. nelsoni is also known as MSX (multinucleated unknown or multinuclear sphere X).
[1] [2] It is known as a prevalent pathogen of oysters, causing massive mortality in oyster populations. The disease it causes is known as dermo or perkinsosis, and is characterized by the degradation of oyster tissues. [3] The genome of this species has been sequenced. [4]
Human exposure seems to be most common via consumption of commonly harvested shellfish such as clams, oysters, and mussels, although it has been proposed that exposure to lower levels of brevetoxins can take place following the consumption of certain planktivorous fish. [4]
Oysters from Canada, specifically Prince Edward Island, live in much cooler water where the risk of Vibrio vulnificus infections is significantly lower. Or if you want to be especially careful ...
Shellfish poisoning includes four syndromes that share some common features and are primarily associated with bivalve molluscs (such as mussels, clams, oysters and scallops.) [1] As filter feeders, these shellfish may accumulate toxins produced by microscopic organisms, such as cyanobacteria, diatoms and dinoflagellates.
