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
Chikungunya virus (CHIKV) is an RNA virus from the family Togaviridae transmitted primarily by Aedes mosquitoes. The first report of CHIKV infection in Brazil dates to 2014; since then, the virus has become a major public health challenge. The main goal of this study was to perform a phylogenetic analysis of CHIKV isolates from ... 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
Quantitative fluorescent polymerase chain reaction (QF-PCR), in recent years, has been accepted as a rapid, high throughput, and sensitive method for prenatal diagnosis of common chromosomal aneuploidies. Since short tandem repeats (STRs) are the cornerstone of QF-PCR technique, selection of the most polymorphic STR markers is an essential step for a successful QF-PCR assay. The genetic ... more
The Ezo red fox (Vulpes vulpes schrencki), a subspecies endemic to Hokkaido island, Japan, is a known host species for the tapeworm Echinococcus multilocularis. To develop tools for molecular ecological studies, we isolated 28 microsatellite regions from the genome of Ezo red fox, and developed 18 polymorphic microsatellite markers. These markers were characterized using 7 individuals and 22 ... more
Cambuci (Campomanesia phaea) belongs to the Myrtaceae family and is native to the Atlantic Forest of Brazil. It has ecological and social appeal but is exposed to problems associated with environmental degradation and expansion of agricultural activities in the region. Comprehensive studies on this species are rare, making its conservation and genetic improvement difficult. Thus, it is ... more
Habitat fragmentation has numerous consequences, particularly to endemic species, and has a negative impact on the genetic diversity of neglected species, leading to genetic drift. Annona crassiflora Mart. is a species that is endemic to Brazil, and its incidence in the Cerrado biome has decreased. The identification and characterization of its remaining diversity is necessary for its ... more
