[Preoperative conjunctival bacterial flora and sensitivity to antibiotics (author's transl)].

2 973 preoperative cultures of conjunctiva have placed in a prominent position 834 pathogenic germs. Cultures in an enriched medium and in an atmosphère including ten per cent of carbonic gas (10% of CO2) have widely increased the number of isolated Streptococus. A study of spectra of antibiotics used in ophtalmology has been made for all these germs. The instability of conjunctival flora with time implies a modification in tactics of bacteriological preoperative samples in order to obtain a better operative security.
