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

Proceedings 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 ...

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

Emerging 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

Molecular Sequence Data of Hepatitis B Virus and Genetic Diversity After Vaccination [PDF]

American Journal of Epidemiology, 2009
The effect of vaccination programs on transmission of infectious disease is usually assessed by monitoring programs that rely on notifications of symptomatic illness. For monitoring of infectious diseases with a high proportion of asymptomatic cases or a low reporting rate, molecular sequence data combined with modern coalescent-based techniques offer ...

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

Memorias 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 ...

Population Subdivision and Molecular Sequence Variation: Theory and Analysis ofDrosophila ananassaeData [PDF]

Genetics, 2003
AbstractPopulation subdivision complicates analysis of molecular variation. Even if neutrality is assumed, three evolutionary forces need to be considered: migration, mutation, and drift. Simplification can be achieved by assuming that the process of migration among and drift within subpopulations is occurring fast compared to mutation and drift in the

Foot-and-Mouth Disease Virus Serotype A in Egypt

Emerging Infectious Diseases, 2007
We describe the characterization of a foot-and-mouth disease (FMD) serotype A virus responsible for recent outbreaks of disease in Egypt. Phylogenetic analysis of VP1 nucleotide sequences demonstrated a close relationship to recent FMD virus isolates ...

Classification of molecular sequence data using Bayesian phylogenetic mixture models [PDF]

Computational Statistics & Data Analysis, 2014
Rate variation among the sites of a molecular sequence is commonly found in applications of phylogenetic inference. Several approaches exist to account for this feature but they do not usually enable the investigator to pinpoint the sites that evolve under one or another rate of evolution in a straightforward manner.

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

Biomédica: 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 ...
