| fulfilling koch's postulates confirms the mycotic origin of lethargic crab disease. | in the northeast region of the brazilian coast, a disease has been causing massive mortalities of populations of the mangrove land crab, ucides cordatus (l.) since 1997. the clinical signs of this disease, which include lethargy and ataxia, led to the disease being termed lethargic crab disease (lcd). evidence from a variety of sources indicates that there is an association between lcd and a new species of black yeast, exophiala cancerae de hoog, vicente, najafzadeh, badali, seyedmousavi & boege ... | 2010 | 21152982 |
| specific primers for the detection of the black-yeast fungus associated with lethargic crab disease (lcd). | lethargic crab disease (lcd) is an emerging infirmity that has been causing extensive mortalities in populations of the mangrove land crab ucides cordatus (ocypodidae) along the atlantic coast of brazil. previous studies have indicated that lcd is associated with a dematiaceous fungus, exophiala cancerae de hoog et al. in the present study, we sequenced the internal transcribed spacer (its) of the rdna region of this black yeast species and developed species-specific pcr primers. sensitivity tes ... | 2011 | 21553569 |
| black yeast-like fungi associated with lethargic crab disease (lcd) in the mangrove-land crab, ucides cordatus (ocypodidae). | lethargic crab disease (lcd) caused extensive epizootic mortality of the mangrove land crab ucides cordatus (brachyura: ocypodidae) along the brazilian coast, mainly in the northeastern region. the disease was named after the symptoms of slow movement of infected crabs. causative agents were suspected to be two black yeast-like fungi of the family herpotrichiellaceae (ascomycete order chaetothyriales), judged by infected tissue biopsies from moribund u. cordatus. the aim of the present study is ... | 2012 | 22440399 |
| black yeast biota in the mangrove, in search of the origin of the lethargic crab disease (lcd). | knowledge of natural ecology is essential for a better understanding of pathogenicity and opportunism in black yeast-like fungi. although etiological agents of diseases caused by these fungi are supposed to originate from the environment, their isolation from nature is difficult. this is probably due to their oligotrophic nature, low competitive ability, and, overall, insufficient data on their natural habitat. we obtained environmental samples from mangrove areas where mortalities by lethargic ... | 2013 | 23539353 |
| is marine dispersion of the lethargic crab disease possible? assessing the tolerance of exophiala cancerae to a broad combination of salinities, temperatures, and exposure times. | since 1997, an emergent fungal disease named lethargic crab disease (lcd) has decimated stocks of the edible mangrove land crab ucides cordatus (linnaeus, 1763) (brachyura: ocypodidae) along the brazilian coast, threatening the mangrove ecosystem and causing socioeconomic impacts. evidence from a variety of sources suggests that the black yeast exophiala cancerae (herpotrichiellaceae, chaetothyriales) has been responsible for such epizootic events. based on the spatiotemporal patterns of the lcd ... | 2017 | 28660465 |
