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...

Evaluation of the melting temperature of TaqMan probes as a genotyping method for IDH1, IDH2, and H3F3A in pediatric astrocytomas

Abstract Background: Astrocytomas are cancer tumors of the central nervous system and represent the most common type of solid tumors during human childhood. In 2016, the World Health Organization established a molecular classification system to regroup tumor entities to achieve a more accurate diagnosis...

Phylogenetic relationships of closely-related phlebotomine sand flies (Diptera: Psychodidae) of Nyssomyia genus and Lutzomyia subgenus

Mem. Inst. Oswaldo Cruz; 115 (), 2020
BACKGROUND The Nyssomyia genus and Lutzomyia subgenus include medical important species that are Latin American leishmaniases vectors. Little is known about the phylogenetic relationships of closely-related species in each of these taxonomic groups that are morphologically indistinguishable or different...

Evidencia molecular de la ocurrencia de bacterias celulolíticas del género Cohnella en especies neotropicales de Nasutitermitinae colectadas en el NEA
Molecular evidence that cellulolytic bacterial genus Cohnella is widespread among Neotropical Nasutitermitinae from NE Argentina

Rev. argent. microbiol; 51 (1), 2019
Cohnella is a highly cellulolytic bacterial genus, which can be found in a variety of habitats. The aim of this study was to assess its presence in the digestive tract of termite species collected in North-eastern Argentina: Nasutitermes aquilinus, N. corniger and Cortaritermes fulviceps. Gut homogenates...

El controvertido complejo Burkholderia cepacia, un grupo de especies promotoras del crecimiento vegetal y patógenas de plantas, animales y humanos
The controversial Burkholderia cepacia complex, a group of plant growth promoting species and plant, animals and human pathogens

Rev. argent. microbiol; 51 (1), 2019
El complejo Burkholderia cepacia está formado por 22 especies conocidas como patógenos oportunistas en personas inmunocomprometidas, especialmente en aquellas con fibrosis quística. También se aíslan de infecciones nosocomiales y son difíciles de erradicar debido a su capacidad intrínseca para res...

Correlation between molecular features and genetic subtypes of Glioblastoma: critical analysis in 109 cases

OBJECTIVE: Glioblastoma, the most common and lethal brain tumor, is also one of the most defying forms of malignancies in terms of treatment. Integrated genomic analysis has searched deeper into the molecular architecture of GBM, revealing a new sub-classification and promising precision in the care for ...

Selective intra-dinucleotide interactions and periodicities of bases separated by K sites: a new vision and tool for phylogeny analyses

Biol. Res; 50 (), 2017
Direct tests of the random or non-random distribution of nucleotides on genomes have been devised to test the hypothesis of neutral, nearly-neutral or selective evolution. These tests are based on the direct base distribution and are independent of the functional (coding or non-coding) or structural (rep...

Molecular phylogeny of Toxoplasmatinae: comparison between inferences based on mitochondrial and apicoplast genetic sequences

Abstract Phylogenies within Toxoplasmatinae have been widely investigated with different molecular markers. Here, we studied molecular phylogenies of the Toxoplasmatinae subfamily based on apicoplast and mitochondrial genes. Partial sequences of apicoplast genes coding for caseinolytic protease (clpC) an...

Presence of Mycobacterium avium subsp. paratuberculosis (MAP) in Brazilian patients with inflammatory bowel diseases and in controls

Säo Paulo med. j; 134 (1), 2016
CONTEXT AND OBJECTIVE: Mycobacterium avium subsp. paratuberculosis (MAP) has attracted the interest of researchers because of similarities between paratuberculosis and Crohn's disease (CD). The aim of this study was to evaluate the frequency of MAP through cultures, histology and polymerase chain reactio...

Sequence-based identification of microbial contaminants in non-parenteral products

Braz. j. pharm. sci; 52 (2), 2016
ABSTRACT Phenotypic profiles for microbial identification are unusual for rare, slow-growing and fastidious microorganisms. In the last decade, as a result of the widespread use of PCR and DNA sequencing, 16S rRNA sequencing has played a pivotal role in the accurate identification of microorganisms and t...
