title: Rise and fall of shigella antibiotic resistance.
abstract: Ampicillin resistance of shigellae first appeared in Omaha in 1971, peaked at 68% between 1973 and 1974, and declined to 7% between 1977 and 1978. This reflected the rise and fall of strains with nine different multiple antibiotic resistance patterns that included ampicillin.
