(2012-05-22)Rickettsia felis was described as a human pathogen almost two decades ago, and human infection is currently reported in 18 countries in all continents. The distribution of this species is worldwide, determined by the ... -
Analysis of gut microbiome profiles in common marmosets (Callithrix jacchus) in health and intestinal disease
(2022-03-15)Chronic gastrointestinal (GI) diseases are the most common diseases in captive common marmosets. To understand the role of the microbiome in GI diseases, we characterized the gut microbiome of 91 healthy marmosets (303 ... -
Analysis of mutational dynamics at the DMPK (CTG)n locus identifies saliva as a suitable DNA sample source for genetic analysis in myotonic dystrophy type 1
(2019-05)Genotype-to-phenotype correlation studies in myotonic dystrophy type 1 (DM1) have been confounded by the age-dependent, tissue-specific and expansion-biased features of somatic mosaicism of the expanded CTG repeat. Previously, ... -
Analysis of TcdB Proteins within the Hypervirulent Clade 2 Reveals an Impact of RhoA Glucosylation on Clostridium difficile Proinflammatory Activities
(2016-03)Clostridium difficile strains within the hypervirulent clade 2 are responsible for nosocomial outbreaks worldwide. The increased pathogenic potential of these strains has been attributed to several factors but is still ... -

Análisis electroforético del Ácido Ribonucleico de rotavirus de Costa Rica: implicaciones epidemiológicas
(Revista Médica del Hospital Nacional de Niños Dr. Carlos Sáenz Herrera: 15(1), 21-30, 1980)Actualmente los rotavirus constituyen los principales agentes etiológicos de las diarreas. Fueron descubiertos mediante la microscopía electrónica en 1973 (1, 5, 6) y por su morfología se denominaron partículas virales ... -
Análisis ultraestructural de membranas de glóbulos grasos lácteos de calostro y leche humana
(Revista de Biología Tropical 31(2):245-250, 1983)Lacteous fat globules with their membranes from human milk and calostrum were studied by scanning and transmission electron microscopy. The first appear as spheroidal structures with some irregularities on the surface. ... -
