Diversification of Neoaves: integration of molecular sequence data and fossils [PDF]

open access: yesBiology Letters, 2006
Patterns of diversification and timing of evolution within Neoaves, which includes almost 95% of all bird species, are virtually unknown. On the other hand, molecular data consistently indicate a Cretaceous origin of many neoavian lineages and the fossil record seems to support an Early Tertiary diversification. Here, we present the first well-resolved

Molecular Description of a Novel Orientia Species Causing Scrub Typhus in Chile

open access: yesEmerging Infectious Diseases, 2020
Scrub typhus is a potentially fatal rickettsiosis caused by Orientia species intracellular bacteria of the genus Orientia. Although considered to be restricted to the Asia Pacific region, scrub typhus has recently been discovered in southern Chile.

Optimizing nucleic acid sequences for a molecular data recorder [PDF]

open access: yesProceedings of the Genetic and Evolutionary Computation Conference, 2017
We recently reported the design for a DNA nano-device that can record and store molecular signals. Here we present an evolutionary algorithm tailored to optimising nucleic acid sequences that predictively fold into our desired target structures. In our approach, a DNA device is first specified abstractly: the topology of the individual strands and ...

Accurate Estimation of Molecular Counts from Amplicon Sequence Data with Unique Molecular Identifiers

open access: yesBioinformatics, 2022
Abstract Motivation Amplicon sequencing is widely applied to explore heterogeneity and rare variants in genetic populations. Resolving true biological variants and quantifying their abundance is crucial for downstream analyses, but measured abundances are distorted by stochasticity and bias in ...

The Quality of Sequence Data Affects Biodiversity and Conservation Perspectives in the Neotropical Damselfly Megaloprepus caerulatus

open access: yesDiversity, 2022
Ideally, the footprint of the evolutionary history of a species is drawn from integrative studies including quantitative and qualitative taxonomy, biogeography, ecology, and molecular genetics.

Molecular Epidemiology of O139 Vibrio cholerae: Mutation, Lateral Gene Transfer, and Founder Flush

open access: yesEmerging Infectious Diseases, 2003
Vibrio cholerae in O-group 139 was first isolated in 1992 and by 1993 had been found throughout the Indian subcontinent. This epidemic expansion probably resulted from a single source after a lateral gene transfer (LGT) event that changed the serotype of

Genotyping of Chlamydophila psittaci in Human Samples

open access: yesEmerging Infectious Diseases, 2006
Chlamydophila (formerly Chlamydia) psittaci genotypes A, B, C, and a new genotype most similar to the 6BC type strain were found in 10 humans with psittacosis by outer membrane protein A gene sequencing.

Identification of Mycobacterium tuberculosis complex based on amplification and sequencing of the oxyR pseudogene from stored Ziehl-Neelsen-stained sputum smears in Brazil

open access: yesMemorias do Instituto Oswaldo Cruz, 2011
A cross-sectional analysis of stored Ziehl-Neelsen (ZN)-stained sputum smear slides (SSS) obtained from two public tuberculosis referral laboratories located in Juiz de Fora, Minas Gerais, was carried out to distinguish Mycobacterium bovis from other ...

El análisis molecular y el inmunogénico sugieren la ausencia de las proteínas hidrofílicas de superficie en Leishmania (Viannia) panamensis

open access: yesBiomédica: revista del Instituto Nacional de Salud, 2008
Introducción. Los dos subgéneros en los cuales se divide el género Leishmania: Viannia y Leishmania, presentan diferencias significativas en las manifestaciones clínicas que causan, en su comportamiento de crecimiento en cultivos in vitro, en sus ...
