Abstract The present study aimed to assess population structure and phylogenetic relationships of nine subspecies of Brassica rapa L. represented with thirty-five accessions cover a wide range of species distribution area using isozyme analysis in order to select more diverse accessions as supplementary ...
INTRODUCCIÓN: Las rickettsiosis son enfermedades emergentes transmitidas por vectores artrópodos cuyos agentes etiológicos corresponden a bacterias patógenas del género Rickettsia y Orientia . Bacterias de este género han sido descritas en el norte y sur de Chile. OBJETIVO: Determinar presencia de ...
Abstract In the present study, pentastomids belonging to the order Cephalobaenida were isolated from the lungs of Berber skinks Eumeces schneideri (Famiy: Scincidae), which were morphologically described by light and scanning electron microscopy and taxonomically justi- fied by 18s rDNA molecular analyse...
La preocupación mundial por el nuevo coronavirus (2019-nCoV), como una amenaza global para la salud pública, fue el motor para que los análisis filogenéticos sufrieran un crecimiento exponencial. El objetivo de esta revisión fue describir el modo de funcionamiento y las bondades de la herramienta Ne...
A Febre Maculosa é uma doença infecciosa febril aguda, com gravidade variável. Em algumas regiões das Américas, uma forma mais branda da doença é causada pela espécie Rickettsia parkeri que é caracterizada por manifestações clínicas mais leves. Atualmente são poucos os estudos epidemiológic...
No Estado de São Paulo, a linhagem Desmodus rotundus/Artibeus
lituratus é prevalente em bovinos e equídeos na área rural, transmitida
por D. rotundus, enquanto na área urbana ela é prevalente em cães e
gatos, transmitida principalmente A. lituratus. Estudo baseado no gene N
e G do RABV evidenciou ...
We propose a revised classification of Doradidae based on phylogenetic analyses of sequence data for one nuclear (rag1) and two mitochondrial (co1, 16s) genes, and corroborated by caudal-fin morphology. The molecular dataset comprises 174 doradid specimens representing all 31 valid genera, 83 of the 96 v...
Venom from Amazonian scorpions of the genus Tityus contains components capable of eliciting a distinct clinical, mostly neurological, syndrome. This contrasts with the mainly autonomic manifestations produced after envenomation by congeneric southern and northern South American species. Herein, we summar...
Lophiosilurus is a monotypic genus represented by L. alexandri, a species endemic to the São Francisco river basin, Brazil. In previous phylogenetic analyses, the genus has been recovered as the sister group of Cephalosilurus. However, few species of Cephalosilurus or few characters were included in tho...
Pathogenic Yersinia enterocolitica (Y. enterocolitica) is one of the food-borne entero-pathogen responsible for yersiniosis in humans. The purpose of this research was to survey the prevalence, virulence-associated genes, and antimicrobial resistance of Y. enterocolitica isolated from meat and meat produ...
