Trichinose expérimentale (2e note)
Longévité et distribution des trichines adultes chez les souris normales et immunotolérantes
Parasitologie et pathologie parasitaire (P r Y. GOLVAN) Faculté de Médecine de Saint-Antoine, 27, rue Chaligny, F. 75 - Paris, 12 e, France.
Les auteurs ont recueilli et dénombré les adultes de Trichinella spiralis dans les différentes portions de l'intestin chez des souris normales et traitées par des injections de cyclophosphamide ou d’ovalbumine.
Ils ont constaté :
- 1°
que la survie des adultes est nettement prolongée chez les souris traitées ;
- 2°
que le rapport nombre de femelles/nombre de mâles, supérieur à un au cours des deux ou trois premières semaines de l’infestation, s’inverse ensuite, et cela dans tous les cas.
Abstract
The adult Trichinella spiralis have been recovered and numbered by the authors in the different parts of the intestine of normal mice and those injected with cyclophosphamide or egg albumine.
The authors have established that:
- 1°
the survival of adults is clearly more important in the treated mice ;
- 2°
the sex ratio (females/males), which is above 1 during the 2 or 3 first weeks of the infection, has then a reversal in the normal and treated mice.
Therefore, either the male worms are less antigenic than females, or more resistant, that is contrary to classic ideas.
