| Popis: |
Adults of Clinostomum marginatum freshly collected from a heron, Ardea herodias, were examined using transmission electron microscopy. Specimens from the mouth of the bird were encrusted with bacteria that were not removed by washing unless the saline contained antibiotics. There was no evidence that the attached bacteria were damaging to the trematode tegument. Three species of Gram-negative bacteria were isolated from the worm surfaces and identified; Achromobacter sp. was present in pure culture on 4 of 6 original cultures and in mixed culture with Edwardsiella tarda and Enterobacter agglomerans in 2 cultures. These species and 3 unidentified species of bacteria were isolated from the oral epithelium of the heron. Microorganisms were not seen attached to the surfaces of worms recovered from the esophagus. Because E. tarda and E. agglomerans were the only species isolated from the heron esophagus, the intimate bacterial-worm association in the heron mouth may be due specifically to Achromobacter sp. |
