I went there and collected sick locusts, easily picked out since their principal symptom was an abundant blackish diarrhoea. This malady had not as yet been described, so I studied it. It was a septicaemia with intestinal symptoms, It was caused by bacteria, the locust coccobacilli, which were present almost in the pure state in the diarrhoeal liquid. I could start epidemics in columns of healthy insects by dusting cultures of the coccobacillus on plants in front of the advancing columns: the insects infected themselves as they devoured the soiled plants… In the course of these researches, at various times I noticed an anomaly, shown by some cultures of the coccocacillus which intrigued me greatly, although in fact the observation was ordinary enough., so banal indeed that many bacteriologists had certainly made it before on a variety of cultures. The anomaly consisted of clear spots, quite circular, two or three millimeters in diameter, speckling the cultures grown on agar.” -- The Bacteriophage by Dr. Felix d'Herelle, Science News 14: 44-59 (1949).
