Rendimiento de diferentes métodos de PCR en el diagnóstico molecular de las rickettsiosis humanas transmitidas por garrapatas
… de PCR que amplifican los genes ADNr 16S, htrA, gltA, ompA y ompB para el diagnóstico molecular de rickettsiosis. Para ello estudiamos 72 muestras (sangre con EDTA, biopsias de piel y garrapatas) de 52 pacientes con rickettsiosis en fase aguda y confimada por PCR. Se realizaron PCRs sencillas …

Regulation and characterization of the nitrogen assimilatory gene cluster in Clostridium acetobutylicum P262
… genetically linked. The a subunit was designated gltA, and the downstream f3 subllll.it was designated gltB. All the likely cofactor and substrate binding sites identified in GOGAT enzymes (Vanoni and Curti, 1999) were conserved in the deduced gltA and gltB polypeptides. The identity of the gltA …

The study of two genes involved in the maintenance of intracellular redox potentials in Thiobacillus ferrooxidans
… amino acid sequence of the T. ferrooxidans gltA gene showed 37% identity to that of E. coli, whereas the predicted amino acid sequence of the T. ferrooxidans gshA gene only showed 18% identity to that of E. coli. The low homology of the gshA gene products is not abnormal, as the …

Molecular detection and characterization of Bartonella in small mammals from southern Africa
… PCR assays targeting the citrate synthase (gltA) and NADH dehydrogenase gamma subunit (nuoG) and/or beta subunit of bacterial RNA polymerase (rpoB) genes were used to ensure enhanced molecular estimates of Bartonella prevalence. Aethomys had the highest infection rate (86.7%), whereas …

High resolution modeling of tick density and detection of Rickettsia spp. in Dermacentor spp. ticks at Turnbull National Wildlife Refuge, WA
… further assessed by amplifying fragments of the gltA and rOmpA genes. Sequencing of the rOmpB gene fragment showed 21 ticks positive for Rickettsia spp. and 6 ticks positive for R. rickettsii. However, both gene fragments (gltA and rOmpA) were positive for Rickettsia peacockii, a non-pathogenic …

Detection of zoonotic bacterial pathogens in multiple hosts using a microbiome approach and molecular characterization of Anaplasma phagocytophilum
… of A. phagocytophilum targeting the 16S rRNA, gltA, ankA and msp4 genes. The bacterial blood microbiome of 25 Mastomys rodent species collected from three habitat areas revealed a total of 65,060 bacterial sequences with 29% of the total sequence reads obtained corresponding to Bartonella …

Studies on the regulation of nitrogen metabolism in clostridium acetobutylicum NCP 262 and clostridium beijerinckii NCIMB 8052
… identified homologues of ginA, glnR and gltA in C. beijerinckii NCIMB 8052, and a clone was isolated from a partial gene library of this organism which complemented glutamine auxotrophy in E. coli YMCll. The clone was sequenced and found to carry two complete and one incomplete ORF's …

Determining role of bacteria associated with bacterial spot on pumpkin and squash fruit in the North Central Region of the United States
… analysis with three housekeeping genes (fusA, gltA, and gyrB) sequenced for each isolate. Results of MLST analysis showed no genetic variation among 20 X. cucurbitae isolates. A phylogenetic tree was generated for various Xanthomonas species using concatenated sequences, which shows a closer …

Estudio de la rickettsiosis transmitida por garrapatas en zonas rurales del departamento del Cauca y la importancia de Amblyomma patinoi en la epidemiología de la enfermedad
… se realizó la búsqueda de genes rickettsiales (gltA, sca5, htrA) y bajo condiciones experimentales se realizaron ensayos de competencia vectorial de A. patinoi y un acercamiento del efecto de la infección de Rickettsia rickettsii sobre genes seleccionados del sistema inmune en esta garrapata. Se …
