Encefalitis amebiana granulomatosa por Balamuthia mandrillaris en Chile confirmada con secuenciación de ADN

Rev. chil. infectol; 41 (1), 2024
Las enfermedades causadas por amebas de vida libre son infecciones oportunistas que pueden tener un curso fatal. Pueden producir afecciones diseminadas graves con compromiso del sistema nervioso central, como la encefalitis amebiana granulomatosa. Esta infección es cada vez más frecuente en América La...

¿Qué hay de nuevo en el diagnóstico de amiloidosis?
What is new in diagnosis of amyloidosis?

La amiloidosis siempre ha representado un desafío diagnóstico. En el año 2020, el Grupo de Estudio de Amiloidosis (GEA), confeccionó la Guía de Práctica Clínica para el Diagnóstico de Amiloidosis. Nuevas líneas de investigación se han desarrollado posteriormente. Esta revisión na...

Genome-sequence, annotation and phylogenetic insights of the lactic acid bacterium Limosilactobacillus fermentum strain LAB1 obtained from the dairy beverage borhani

Acta sci., Biol. sci; 45 (), 2023
Limosilactobacillus fermentum is a promising probiotic with several documented health benefits. LAB1 is an antagonistic L. fermentum strain isolated from borhani, a traditional South Asian beverage prepared from dairy and plant ingredients. Here, I present the genome sequence of the L. fermentum LAB1 str...

The influence of primer choice on archaeal phylogenetic analyses based on 16S rRNA gene PCR

Braz. j. biol; 83 (), 2023
Abstract Polymerase chain reaction (PCR) assays targeting 16S rRNA genes followed by DNA sequencing are still important tools to characterize microbial communities present in environmental samples. However, despite the crescent number of deposited archaeal DNA sequences in databases, until now we do not ...

DNA sequencing in the classroom: complete genome sequence of two earwig (Dermaptera; Insecta) species

Biol. Res; 56 (), 2023
BACKGROUND: Despite representing the largest fraction of animal life, the number of insect species whose genome has been sequenced is barely in the hundreds. The order Dermaptera (the earwigs) suffers from a lack of genomic information despite its unique position as one of the basally derived insect grou...

Standardization of an organic DNA extraction method from dried blood spots and its downstream molecular applications in neonatal screening and diagnostic confirmation of lysosomal disorders

Clin. biomed. res; 42 (3), 2022
Introduction: Dried blood spot (DBS) samples have been used for diagnostic purposes since their introduction in the neonatal screening of phenylketonuria almost 50 years ago. The range of its application has been extended to modern approaches, such as next-generation sequencing (NGS) for molecular geneti...

sideRETRO: uma ferramenta de bioinformática dedicada à identificação deinserções polimórficas, germinativas ou somáticas, de pseudogenes processados

Os avanços metodológicos e instrumentais decorrentes do Projeto Genoma Humano formaram o arcabouço necessário para o surgimento das tecnologias de sequenciamento de DNA de Nova Geração, as quais se caracterizam por um custo reduzido, uma baixa demanda operacional e a produção de um grande volume ...

Sequence analysis of the internal transcribed spacer 2 (ITS2) region of rDNA for identifying Trichogramma species and evaluating genetic diversity

Braz. j. biol; 81 (4), 2021
Abstract Species of Trichogramma Westwood, 1833 (Hymenoptera: Trichogrammtidae) are frequently used as biological control agents against Lepidoptera, but practical application of these egg endoparasitoids are complicated because of their complex taxonomy. This study aimed to compare sequences of internal...
