El Bosque de Prosperina es un área protegida ubicada en la ciudad de Guayaquil-Ecuador donde existe una gran diversidad de plantas, animales y, últimamente, microorganismos que contribuyen a su conservación y mantenimiento. Las muestras de suelo recogidas en las estaciones de Cuevas, Cañas y FCV durante la estación seca se analizaron mediante métodos microbiológicos convencionales. Como resultado, se identificaron 38 especies, y en cada estación se obtuvieron 16, 16 y 16, respectivamente. Los géneros más frecuentes encontrados en las tres estaciones son Aspergillus, Penicillium, Trichoderma y Absidia, con menor frecuencia Fusarium, Cladosporium, Talaromyces, Cur-vularia, Humicola, Gongronella, Clonostachys y Mariannea. Se crioconservaron 38 cepas de hongos filamentosos en la Colección de Cultivos de microorganismos del CIBE (CCM-CIBE), de las cuales 36 eran especies únicas. Los resultados obtenidos sugieren que las especies encontradas. Su desplazamiento puede verse afectado por factores naturales y humanos. Además, confirmamos microorganismos biocontroladores como Purpureocillium, un nematófago y Cladosporium que, pueden tener un alto potencial en actividades de biorremediación de im-portancia para la agricultura y recuperación de suelos, lo que corrobora que el Bosque de Protección es una rica fuente de microorganismos con una gran reputación para su conservación. Palabras clave: Bosque Protector, microdiversidad del suelo, biocontrol, conservación.
Background For public health policy, this study aimed to identify the oral microbiota in babies of the Amazonian Kichwa (AK) population of Ecuador born vaginally during the first six months of life. Method The study was descriptive, observational, cross‐sectional, where the bacterial communities of infants were analyzed. Twenty‐five infants self‐identified as AK were recruited from 2 rural areas (Ñucanchi‐Llacta and Pano) and one urban area (center of Tena) of Ecuador. Saliva samples were collected from the infants using the self‐collection kit. DNA was extracted from salivary samples, bacterial amplicons (16S) were generated and sequenced using Nanopore MinION, and the sequences were pre‐processed and data analyzed using EPI2ME. Results High bacterial diversity was observed in infants' saliva [2191 operational taxonomic units with 1% divergence]. Firmicutes and Proteobacteria were the predominant bacterial phyla present in all samples. A total of 10 bacterial genera were present in our data set. The predominant genera in infant saliva were Streptococcus, Staphylococcus, Bacillus, Gemella, and Veillonella. Conclusion our data show a rich bacterial community in the baby's oral cavity. The oral microbiota of the infants was relatively stable during the period studied and was very similar between them. Such similarity may result from maternal child care habits (e.g., kissing on the mouth). Further research is required to characterize the development of the oral microbiota early in life and identify environmental factors that affect colonization and the risk of oral and gastrointestinal diseases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
