[Morphological changes induced by ampicillin in Campylobacter].
Morphologic changes in Campylobacter fetus ssp. jejuni were evaluated as cultivated on thioglycollute broth, containing minimum of 0.1, 1.3 and 10 Ampicillin minimal inhibitory concentration (MIC). During the first four hours of incubation, no changes occurred in the presence of 0.1 MIC; but with the rest of the ampicillin doses, even at the first hour, a proportion larger than 5% of filament-policurved forms was found, and it increased with the incubation time. The greatest number of altered bacteria was found with the use of 10 MIC. No other morphologic changes were observed.
