dc.description.abstract Scanning electron microscopy was used to detect the presence of microorganisms on the internal intestinal surface of Onychochaeta borincana. The intestines of fourteen adult specimens were extracted, washed, and prepared through microscopy protocol. Samples from organisms exposed to sterile soil show similar microorganisms in their intestine than those not submitted to this cleaning treatment. Different microorganisms were observed. The presence of segmented filamentous bacteria was evident throughout the entire intestinal wall. Also, round and rod-shaped bodies were observed. Furthermore, non-characterized microorganisms with network arrangements were observed in the mucus of the epithelial tissue. en_US
dc.description.abstract La microscopía electrónica de rastreo se utilizó para detectar la presencia de microorganismos en la superficie interna del tubo digestivo de Onychochaeta borincana. El intestino de catorce especímenes adultos fue extraído, lavado y preparado según el protocolo de microscopía. Las muestras provenientes de los organismos expuestos a terreno estéril mostraron microorganismos similares en su intestino a aquellos individuos que no fueron sometidos a este tratamiento de limpieza. Diferentes microorganismos fueron observados. La presencia de bacterias filamentosas adheridas a toda la pared intestinal es evidente. También se hallaron cuerpos cocoides y baciliformes. Además se logró observar unos microorganismos reticulares no caracterizados, asociados a la mucosidad del tejido epitelial. en_US
