Abstract
DURING the past two years, attempts have been made in this laboratory to keep alive in vitro sterile trematodes of the species Haplometra cylindracea (Zeder, 1800) obtained by aseptic dissection from the lungs of frogs (Rana temporaria). Of the 338 frogs dissected to date, 194 were uninfected with this trematode and the remaining 144 frogs provided a total of 576 living flukes. One remarkable frog had 23 flukes in the left lung and 17 in the right lung; but the majority of infected frogs had either two or three flukes in each lung.
