Laboratory for Medical Microbiology, State University of Groningen, The Netherlands.

11 volunteers received 1 g ceftriaxone i.m. every 24 h for 5 consecutive days. Volunteers were selected on the basis of the "ceftriaxone inactivating capacity" of their faeces, which should be 250 mg/kg faeces. The effect of treatment on the aerobic oral and faecal flora was studied. In the oral flora a temporary suppression of the viridans streptococci occurred, which normalised already during treatment. More spectacular was the effect on the faecal flora: suppression of aerobic Gram-negative bacilli with overgrowth of yeasts and enterococci. Two weeks after treatment the results of the faecal cultures were almost the same as before treatment in most of the volunteers. One volunteer experienced severe diarrhoea, starting the day after completion of ceftriaxone treatment and lasting 2 days.

D006088 Gram-Negative Aerobic Bacteria A large group of aerobic bacteria which show up as pink (negative) when treated by the gram-staining method. This is because the cell walls of gram-negative bacteria are low in peptidoglycan and thus have low affinity for violet stain and high affinity for the pink dye safranine. Achromatiaceae,Achromatium,Achromobacteriaceae,Gram Negative Aerobic Bacteria
