Abstract Background The protozoan Trypanosoma cruzi circulates in semiarid areas of northeastern Brazil distinct ecotopes (sylvatic, peridomestic and domestic) where Triatoma brasiliensis Neiva, 1911 is the most important Chagas disease vector. In this study, we analyzed microevolutionary demographic aspects T. populations at ecotypic, micro macro-geographic scales by combining morphometrics molecular results. Additionally, aimed to address resolution both markers for delimiting scales....
Two species of manatees are found in Northern Brazil-the Antillean manatee (Trichechus manatus), which is along the coast from Florida to Northeastern Brazil, and Amazonian inunguis), endemic Amazon drainage basin. These show a sympatric distribution region Marajó Archipelago, an estuarine area surrounding River mouth. There evidence occurrence interspecific hybrids this area, based on mitochondrial DNA analyses, although use nuclear markers has not corroborated proposal. Considering that...
A large geographic differentiation has been reported in Sylvilagus brasiliensis based on external characters and a small number of samples. Karyologic molecular studies as well new sampling efforts are need to better understanding the S. complex diversity. karyotype with 2n=40 FNa=74 from Rio de Janeiro is here reported. Phylogenetic analyses cytochrome b DNA sequence eight samples states Paraíba, Tocantins, Goiás, Minas Gerais suggested strong structured population. Both, karyotypic data...
The human population of the Brazilian Amazon possesses a rich body beliefs and practices that relate to river dolphins, which are also known as botos (Inia Sotalia species). There is widespread belief in their magical powers relation love enchantments. One form this takes 'dolphin charms' these widely use northern Brazil, largest southern cities. This paper considers trade cetacean products charms Brazil. Samples were obtained north (n=70), northeast (n=3) southeast (n=59) regions from 34...
South America is unique as it home of two species manatees: the West Indian manatee, Trichechus manatus, and Amazonian T. inunguis. These are easily identified by belly skin coloration, first entirely gray whereas inunguis has a white mark pattern in belly, presence nails absent The morphology range have been clearly established. However, we show that coloration on pectoral flipper may be polymorphic. findings prompted us to check all available information about manatee. In view lack...
Normal 0 21 The genus Alouatta Lacépède 1799 comprises a group of neotropical primates distributed from southern Mexico to northern Argentina. Ten species occur in Brazil, including belzebul (Linnaeus, 1766) and A. ululata Elliot, 1912; this latter being considered full or junior synonymous A . In order clarify the relationship with inferring their relationships other species, karyotyping mitochondrial DNA data were analyzed. Phylogenetic analyses carried out 801 pb fragment cytochrome b one...
Here we report the first record of genus Cryptonanus in state Rio de Janeiro, Brazil. One specimen (MZUSP35409) was captured an Atlantic Forest fragment and identified by morphological characters molecular analysis using cytochrome‑b (MT-CYB) von Willebrand Factor (VWF). Phylogenetic reconstructions based on VWF sequences positioned our into Cryptonanus, shortest genetic distance MT-CYB estimated between undescribed from Piauí. Our increases genus’ geographic range approximately 350 km Cotia...
The swamp rats are distributed in Argentina, southern Paraguay, Uruguay and Brazil, with two species currently accepted: Scapteromys aquaticus Thomas, 1920 tumidus Waterhouse, 1837. While S. occurs Paraguay western Uruguay, Brazil Uruguay. Here we report for the first time occurrence of gallery forest remnants Southern Brazil. Karyologic analysis showed 2n = 32 FNa 40. Phylogenetic analyses, based on DNA sequences from mitochondrial cytochrome-b gene indicate that Brazilian Argentinian...

The methyl-CpG Binding Protein two gene (MECP2) encodes a multifunctional protein comprising isoforms involved in nuclear organization and regulation of splicing mRNA template activity. This is normally expressed all tissues, with higher expression level the brain during neuronal maturation. Loss MECP2 function primary cause Rett syndrome (RTT) humans, dominant, X-linked disorder dramatically affecting neural motor development.We investigated molecular evolution several primate taxa...
Due to immunosuppressive cancer therapies, patients diagnosed with COVID-19 have a higher chance of developing severe symptoms and present mortality rate in comparison the general population. Here we show comparative analysis microbiome from naso-oropharyngeal samples breast respect SARS-CoV-2 status identified bacteria associated symptom severity. Total DNA swabs 74 women or without cancer, positive negative for were PCR-amplified 16S-rDNA V3 V4 regions submitted massive parallel...
Traditionally, the morphological attributes and range of Trichechus species have been clearly established. However, we herein show that traits, like belly pectoral flipper coloration in South American manatees may be polymorphic. Karyotypic analysis T. manatus allowed precise identification this confirmed variability observed findings. Molecular based on cytochrome b DNA D-loop mitochondrial region showed shared haplotypes between inunguis , suggesting presence an ancestral polymorphism....

The tumor suppressor, Human Retinoblastoma Susceptibility Gene (RB1) plays a prominent role in normal development, gene transcription, DNA replication, repair, and mitosis, its complete biallelic dysfunction retinoblasts is the main cause of retinoblastoma humans. Comparisons between reference, human RB1 coding region with counterparts 19 non-human primates showed that several alterations accompanying were present without apparent pathological effects. Comparative analyses molecular data...
