Caracterización genética de bacterias endofíticas de arroz (Oryza sativa L.) con actividad antimicrobiana contra Burkholderia glumae

Rev. argent. microbiol; 52 (4), 2020
Resumen La demanda de xilanasas fúngicas en los procesos biotecnológicos industriales muestra un claro aumento en todo el mundo, por lo que hay un interés en ajustar las condicionesde producción de xilanasas microbianas. En este estudio se optimizó la capacidad del hongoFusarium solani para producir...

Antagonic and plant growth-promoting effects of bacteria isolated from mine tailings at El Fraile, Mexico

Rev. argent. microbiol; 52 (3), 2020
Abstract Mine tailings contain high concentrations of heavy metals such as As, Pb, Cu, Mn, andFe, which are detrimental to the health of humans and the environment. In tailings at the ElFraile mine in Guerrero, Mexico, some plant species are apparently tolerant of heavy metals andcan be found growing in ...

Isolation and characterization of hydrocarbon-degrading bacteria from gas station leaking-contaminated groundwater in the Southern Amazon, Brazil

Braz. j. biol; 80 (2), 2020
Abstract Twenty-three hydrocarbon-degrading bacteria strains were isolated from gas station leaking-contaminated groundwater located in the Southern Amazon, Brazil. Based on hydrocarbon (diesel, hexadecane, benzene, toluene and xylene) degradation ability, two strains were selected for further study. The...

Investigación traslacional en microbioma (InTraMic): un área de interés común y creciente en el IMTIB, Hospital Italiano e Instituto Universitario
Translational research in microbiome (InTraMic): an area of common and growing interest at IMTIB, Hospital Italiano and Instituto Universitario

Se estima que aproximadamente 100 trillones de microorganismos (incluidos bacterias, virus y hongos) residen en el intestino humano adulto y que el total del material genético del microbioma es 100 veces superior al del genoma humano. Esta comunidad, conocida como microbioma se adquiere al momento del n...

Composition of the bacterial community in the gastrointestinal tract of Kunming mice

Background: The intestinal bacterial community has an important role in maintaining human health. Dysbiosis is a key inducer of many chronic diseases including obesity and diabetes. Kunming mice are frequently used as a model of human disease and yet little is known about the bacterial microbiome residen...

Survey of vector-borne and nematode parasites involved in the etiology of anemic syndrome in sheep from Southern Brazil

Abstract Although anemia has been historically linked to Haemonchus contortus infection, other infectious agents, such as hemotropic mycoplasmas and tick-borne disease pathogens, may also lead to anemic crisis in sheep. This study has aimed to investigate infections related to anemia in a sheep herd from...

Detection of tick-borne rickettsial pathogens in naturally infected dogs and dog-associated ticks in Medellin, Colombia

Abstract Tick-borne rickettsial pathogens (TBRP) are important causes of infections in both dogs and humans. Dogs play an important role as a biological host for several tick species and can serve as sentinels for rickettsial infections. Our aim was to determine the presence of TBRP in dogs and in dog-as...

Phylogenetic Group/Subgroups Distributions, Virulence Factors, and Antimicrobial Susceptibility of Escherichia coli Strains from Urinary Tract Infections in Hatay

Abstract INTRODUCTION: Nosocomial and community acquired urinary tract infections (UTIs) are one of the most encountered infections in the world. METHODS: This study aimed to determine the antibiotic susceptibility, phylogeny, and virulence genes of 153 Escherichia coli strains isolated from UTIs. An...

New molecular target for the phylogenetic identification of Leptospira species directly from clinical samples: an alternative gene to 16S rRNA

Abstract INTRODUCTION: Phylogenetic analysis of the 16S ribosomal gene initial region is used to identify Leptospira isolates at the species level from clinical samples. Unfortunately, this method cannot differentiate between some intermediates and saprophytic species. METHODS: We used comparative geno...

Molecular detection of Cercopithifilaria bainae and other tick-borne pathogens in Rhipicephalus sanguineus s.l. isolated from dogs in Midwest Brazil

Abstract The aim of the present study was to detect Cercopithifilaria bainae and other tick-borne pathogens and to perform molecular characterization of the tick Rhipicephalus sanguineus s.l. collected from dogs. Ticks (n = 432, including 8 larvae, 59 nymphs, and 365 adults) were sampled from domiciled d...
