Arthropod-borne agents in wild Orinoco geese (Neochen jubata) in Brazil
(2017-12-01)
Although Orinoco goose (Neochen jubata) is an anatid species widely distributed in South America, scarce are the reports on the occurrence of arthropod-borne pathogens in this avian species. The present work aimed to verify, ...
Wolbachia strains in cryptic species of the Anastrepha fraterculus complex (Diptera, Tephritidae) along the Neotropical Region
(2017-01-01)
Infection by Wolbachia was described previously in eleven species of Anastrepha fruit flies some of which are important pests of fruticulture. One such species is the nominal Anastrepha fraterculus, the South American fruit ...
A New Fitness Function for Evolutionary Music Composition
In this paper we propose a new fitness function for Evolutionary Computation purposes, based on a weighted by neighborhood average distance between two sequences of points within any metric space. We will apply this fitness ...
Human Caliciviruses Are a Significant Pathogen of Acute Sporadic Diarrhea in Children of Santiago, Chile
(2000)
Human caliciviruses (HuCVs) are increasingly recognized as common pathogens that cause
acute sporadic diarrhea in children; however, regional antigenic and genetic diversity complicate
detection techniques. Stool samples ...
Lack of genetic structure in Pantala flavescens among Central and South American localities (Odonata: Libellulidae)
(Soc Int Odonatologica, 2017-06)
Pantala flavescens is the most widespread odonate on Earth, absent only in Antarctica and parts of Europe. A recent study performed with sequences of mtDNA suggested the presence of one panmictic population of the species ...
Nuclear and plastid SNP markers for tracing Cedrela timber in the tropics
(2019-01-01)
Illegal logging and trade of timber are major worldwide concerns, resulting in biodiversity and economic losses. Tropical tree species in the genus Cedrela, which have historically been heavily exploited, are still often ...
Heteroplasmy in hair: Differences among hair and blood from the same individuals are still a matter of debate
(Elsevier B.V., 2007-12-20)
The analysis of mitochondrial DNA (mtDNA) is a useful tool in forensic cases when sample contents too little or degraded nuclear DNA to genotype by autosomal short tandem repeat (STR) loci, but it is especially useful when ...
Variação de número de cópias revela extensa plasticidade genômica no parasito Trypanosoma cruzi
(Universidade Federal de Minas GeraisUFMG, 2017-06-27)
Trypanosoma cruzi is the etiologic agent of Chagas disease, a chronic illness that affects ~5-8 million people worldwide. This parasite has extreme genotypic and phenotypic variability, with several aneuploidies and a ...
Biallelic HERC1 mutations in a syndromic form of overgrowth and intellectual disability
We report two Colombian siblings affected by overgrowth, intellectual disability and facial dysmorphism. Exome (via NGS) and Sanger sequencing revealed that biallelic sequence variants in a novel gene (HERC1) might be ...
Is the free-ranging jaguar (Panthera onca) a reservoir for Cytauxzoon felis in Brazil?
(2017-06-01)
This study investigated the occurrence of Cytauxzoon felis and Babesia spp. in free-ranging jaguars (Panthera onca), domestic dogs (Canis lupus familiaris) and domestic cats (Felis catus) from the Cerrado, Amazon and ...
