Aborted ovine placenta. A. Detection of Campylobacter fetus by fluorescence in situ hybridization (FISH) in the placenta of case B3. Numerous C. fetus organisms (specific orange fluorescence signal from probe Cafet) are distending the cytoplasm of infected trophoblasts as well as invading the underlying chorionic villus stroma. B. Detection of Campylobacter jejuni by FISH in the placenta from case D1. Trophoblasts and subepithelial capillaries are severely distended as a result of accumulation of numerous C. jejuni organisms (orange). C. jejuni organisms also invade the villus stroma.
