Hematodinium sp. infections are relatively common in some American blue crab (Callinectes sapidus) populations in estuaries of the western Atlantic Ocean. Outbreaks of disease caused by Hematodinium sp. can be extensive and can cause substantial mortalities in blue crab populations in high salinities. We examined several species of crustaceans to determine if the same species of Hematodinium th...

Background and Purpose: Cryptococcus species are pathogenic and non-pathogenic basidiomycete yeasts that are found widely in the environment. Based on phenotypic methods, this genus has many species; however, its taxonomy is presently being re- evaluated by modern techniques. The Cryptococcus species complex includes two sibling taxa of Cryptococcus neoformans and Cryptococcus gattii. We aimed ...

Two Peruvian strains of the genus Brachionus were isolated from impacted coastal wetlands. With an integrative taxonomic view, we described their status, morphological characters, productive parameters, and phylogenetic position. In case both strains, relationship between biometrics parameters obtained with Principal Components Analysis indicated that lorica length was associated longevity, pro...

Faba bean gall (FBG) is a devastating disease of faba (Vicia faba) in Ethiopia. Studies were undertaken first to compare and contrast similarities between FBG symptoms morphology Ethiopia with those reported earlier China and, secondly, identify definitively the causal agent, previously considered as Olpidium viciae, through molecular studies. Morphological studies confirmed an epibiotic phase ...
