The authors used Albendazole in a single dose of 400 mg in 40 students from Africa and Asia, infected with Ascaris lumbricoides, Trichocephalrus trichiurus and Ancylostomatidae. At the third day after the treatment no parasite eggs have been found in 25 of 30 cases of ancylostomatidosis (83.3%), 16 of 23 cases of trichocephalosis (69.6%) and in all treated cases of ascaridosis (100%). It has been also found that the tolerance for the medicine is good in most patients. Only in two patients (2%) there appeared short time and not very strong pains in the upper part of the abdomen and headaches. An important property of Albendazole is its ability to destroy nematode eggs which is essential for the prophylaxis and nature conservation.
