| rediscovery of the yesso scallop pathogen perkinsus qugwadi in canada, and development of pcr tests. | perkinsus qugwadi, a pathogenic protozoan parasite of yesso scallops patinopecten yessoensis, is found only in cultured populations in british columbia, canada. this pathogen was first identified in 1988 and caused significant mortalities at some locations during the early 1990s. prevalence of infection decreased dramatically following 1995, and the disease was last reported in 1997, leading to speculation that the yesso scallop stocks in canada had developed resistance to the disease, or that p ... | 2013 | 23670082 |
| fine structure of clonally propagated in vitro life stages of a perkinsus sp. isolated from the baltic clam macoma balthica. | we established monoclonal in vitro cultures of a perkinsus sp. isolated from the baltic clam macoma balthica and compared morphological features of various life stages by light and transmission electron microscopy to those of the currently accepted perkinsus species: perkinsus marinus, perkinsus olseni, perkinsus atlanticus, and perkinsus qugwadi. except that trophozoites were slightly larger than those of p. marinus, and that they underwent zoosporulation in culture, observation of our isolate ... | 2001 | 11249192 |
