Abstract: SummaryMorphology of viable but non‐culturable Vibrio cholerae was monitored for 2 years by scanning and transmission electron microscopy. Morphological changes included very small coccoid forms, after extended incubation at 4°C and room temperature, and sequential transformation from curved rods to irregular (∼1 μm) rods to ∼0.8 μm coccoid cells and, ultimately, to tiny coccoid forms (0.07–0.4 μm). Irregular rod‐shaped and coccoid cells were equally distributed in microcosms during the first 30–60 days of incubation at both tem...
