Cytogenetic mapping of H1 histone and ribosomal RNA genes in hybrids between catfish species Pseudoplatystoma corruscans and Pseudoplatystoma reticulatum
(2013-01-01)
A physical chromosome mapping of the H1 histone and 5S and 18S ribosomal RNA (rRNA) genes was performed in interspecific hybrids of Pseudoplatystoma corruscans and P. reticulatum. The results showed that 5S rRNA clusters ...
Diversity of cry genes and genetic characterization of Bacillus thuringiensis isolated from Brazil
(2004-08-01)
Two hundred and eighteen Bacillus thuringiensis isolates from Brazil were characterized by the presence of crystal protein genes by PCR with primers specific to different cry and cyt genes. Among these isolates, 95 were ...
Genetic diversity of elite rhizobial strains of subtropical and tropical legumes based on the 16S rRNA and glnII genes.
(World Journal of Microbiology and Biotechnology, Oxford, v. 26, n. 7, p. 1291-1302, jul. 2010., 2010)
Multiple ribosomal RNA operons in bacteria; their concerted evolution and potential consequences on the rate of evolution of their 16S rRNA
(Frontiers Media, 2018-06)
Bacterial species differ greatly in the number and location of the rRNA operons which may be present in the bacterial chromosomes and plasmids. Most bacterial species contain more than one ribosomal RNA operon copy in their ...
Novel genotypes in Helicobacter pylori involving domain V of the 23S rRNA gene
(BLACKWELL PUBLISHING, 2007-10)
Helicobacter pylori
is a pathogenic bacterium that infects a half of
the human population. In Chile, between 55% and 79% of people are colonized
by
H. pylori
. At present, therapeutic strategies to eradicate the ...
Integration of miRNA and mRNA expression profiles reveals microRNA-regulated networks during muscle wasting in cardiac cachexia
(2017-12-01)
Cardiac cachexia (CC) is a common complication of heart failure (HF) associated with muscle wasting and poor patient prognosis. Although different mechanisms have been proposed to explain muscle wasting during CC, its ...
Polymorphism and gene conversion of the 16S rRNA genes in the multiple rRNA operons of Vibrio parahaemolyticus
(ELSEVIER SCIENCE BV, 2005-05-15)
The genome sequence of a strain of Vibrio parahaemolyticus holds 11 copies of rRNA operons (rrn) with identical 16S rRNA genes (rrs). Conversely, the species type strain contains two rrs classes differing in 10 nucleotide ...
Intraspecific variation in 16S rRNA gene of Mycoplasma synoviae determined by DNA sequencing
(ELSEVIER SCI LTD, 2010)
Mycoplasma synoviae (MS) is an important avian pathogen may cause both respiratory disease and joint inflammation synovitis in poultry, causing economic losses to the Brazilian poultry industry. The genotypic variation in ...
Sensitivity evaluation of a single-step PCR assay using Ehrlichia canis p28 gene as a target and its application in diagnosis of canine ehrlichiosis
(Colégio Brasileiro de Parasitologia Veterinária, 2010-06-01)
O objetivo deste estudo foi aperfeiçoar um ensaio de PCR que amplificasse um fragmento de 843 pares de bases do gene p28 da Ehrlichia canis e compará-lo com outros dois métodos de PCR utilizados para amplificar partes do ...
Sensitivity evaluation of a single-step PCR assay using Ehrlichia canis p28 gene as a target and its application in diagnosis of canine ehrlichiosis
(Colégio Brasileiro de Parasitologia Veterinária, 2010)
The aim of this study was to optimize a PCR assay that amplifies an 843 pb fragment from the p28 gene of Ehrlichia canis and compare it with two other PCR methods used to amplify portions of the 16S rRNA and dsb genes of ...
