title: [Effect of dietary proteins on the multiplication of the protozoon Nosema apis Z].
abstract: By counting the spores of protozoon Nosema apis Z. in Bürker's chamber the author was able to find, in 1495 caged bees sacrificed one week after the parasite invasion, from altogether 26 samples of various feeds statistically sifnificant differences of influencing the protozoon development only in sallow pollen. The differences between the individual feeds were statistically more significant in bees sacrificed 14 days after the invasion. Examination of 1260 bees 14 days after the invasion demonstrated that, as compared with glycide food, the parasite development was enhanced by a feed consisting of 6, 9, and 12 per cent fresh rape pollen, 3 and 6 per cent of fresh and dried sallow pollen, 6 per cent freeze-dried pollen mixture, pollen deposited in honeycombs, 7.5, 10, and 12.5 per cent yeast dough, "Arnika" and 3 per cent Bacto peptone. Even 14 days after the invasion no statistically sifnificant differences of influencing the schizogony of protozoon Nosema apis Z. could be demonstrated in bees fed pure glycide feed, dough with 3 and 6 per cent casein hydrolyzate, 3 and 6 per cent Hammarsten casein, 3 per cent dried whole eggs, 3 per cent rape pollen and 3 and 6 per cent fresh pollen mixtures. In the study the possibility of an indirect effect of pollen on the parasite schizogony through the secrete of the pharyngeal glands is being discussed.
