A functional ferric uptake regulator (Fur) protein in the fish pathogen Piscirickettsia salmonis
(CIENCIAS, 2016)Piscirickettsia salmonis, a Gram-negative fastidious facultative intracellular pathogen, is the causative agent of the salmonid rickettsial septicemia (SRS). The P. salmonis iron acquisition mechanisms and its molecular ... -
Actividad antifúngica de melanina en cepas clínicas de Candida spp.
(Facultad de Ciencias, 2014)Introducción: Los melanocitos son células presentes en piel y en mucosas que sintetizan melanina, además de citoquinas. Es sabido que melanina presenta actividad antimicrobiana y que los melanocitos se melanizan al ser ... -
Biofilm formation of mucosa-associated methanoarchaeal strains
(CIENCIAS, 2014)Although in nature most microorganisms are known to occur predominantly in consortia or biofilms, data on archaeal biofilm formation are in general scarce. Here, the ability of three methanoarchaeal strains, Methanobrevibacter ... -
First Report of Vibrio tubiashii Associated with a Massive Larval Mortality Event in a Commercial Hatchery of Scallop Argopecten purpuratus in Chile
(CIENCIAS, 2016)The VPAP30 strain was isolated as the highly predominant bacteria from an episode of massive larval mortality occurring in a commercial culture of the Chilean scallop Argopecten purpuratus. The main aims of this study were, ... -
Microbial degradation of 2,4-dichlorophenoxyacetic acid: Insight into the enzymes and catabolic genes involved, their regulation and biotechnological implications
(CIENCIAS, 2016)A considerable progress has been made to understand the mechanisms of biodegradation of 2,4-dichlorophenoxyacetic acid (2,4-D). 2,4-D biodegradation pathway has been elucidated in many microorganisms including Cupriavidus ... -
Multi Locus Sequence Typing scheme for Acidithiobacillus caldus strain evaluation and differentiation
(CIENCIAS, 2014)Phenotypic, metabolic and genetic properties of several Acidithiobacillus caldus strains indicate the existence of as yet undefined levels of variation within the species. Inspite of this, intraspecies genetic diversity ... -
Stg fimbrial operon from S. Typhi STH2370 contributes to association and cell disruption of epithelial and macrophage-Like cells.
(Facultad de Ciencias, 2015)Salmonella enterica serovar Typhi (S. Typhi) stg operon, encoding a chaperone/usher fimbria (CU), contributes to an increased adherence to human epithelial cells. However, one report suggests that the presence of the Stg ...
