Method "Parasite 1 originated from the superficial marine sediment layer (~10 m deep) taken at the mouth of the Tunquen river (coast of central Chile). Parasite 2 originated from mud taken at the bottom of a shallow freshwater pond near Melbourne, Australia. After amplification on Acanthamoeba cultures, both parasites became observable by optical microscopy as a lawn of ovoid particles 1µm in length and 0.5µm in diameter (Fig. 1A)."
Comments "Observations by transmission electron microscopy revealed characteristic ultrastructural features (Fig. 1) common to both parasites. Despite their identical appearance, the micro-organisms showed different global protein contents when profiled by electrophoresis (Fig. 1C). Anticipating the demonstration of their viral nature, parasites 1 and 2 will henceforth be referred to as Pandoravirus salinus and Pandoravirus dulcis."
