The natural history of mimiviruses (i.e., viruses that are members of the Mimivirus genus) is a challenge for modern biology. A new domain of life to include these organisms has been proposed from analysis of gene conservation. We analyzed the evolutionary relationship of proteins involved in the translation system, and our data show that mimiviruses are a sister group of Eukarya. New data ... more
The parasitic protozoan Perkinsus marinus (Perkinsidae) is known to infect marine bivalves; unfortunately, treatment options are quite limited. The parasite is associated with mass mortalities worldwide and it requires notification to the World Organization for Animal Health (OIE). In Brazil, since the first report of P. marinus infecting ... more
Francisella noatunensis subsp. orientalis (Fno) is a Gram-negative bacterium that causes granulomatous infections in fish reared at low water temperatures; it has been responsible for a large number of deaths in tilapia fish farms. Fno has been reported in many countries in the last decade. Studies on phylogenomic relationships among isolates are ... more
Molecular characterization of genes is a tool used to understand gene function. Chitin is the most abundant nitrogenous organic compound in nature; it is basically inert, but it can be transformed by the action of chitinases to several derivatives, which are of great interest in various areas of industry. These enzymes are widely distributed in many organisms and ... more
The genus Corydalis (Papaveraceae), which is distributed in temperate regions of the northern hemisphere, has been taxonomically studied mainly on the basis of morphological and molecular genomic information. In the present study, 14 species that belong to the Korean section Corydalis were collected in South Korea and phylogenetically analyzed ... more
