“One day late in the night in our parasitology laboratory upon finishing density gradient centrifugation of Blastocystisculture, I took a layer of Blastocystisand placed over a slide and observed under 40 X objective. The Blastocystishorde reminded me of the full moon with conspicuous craters. Immediately I took multiple pictures with my mobile phone to bring my imagination into reality.” (Photo by Shashiraja Padukone)
