Attempts to induce mycetoma in monkeys and mice using Madurella mycetomi

Pages 258-262 | Published online: 09 Jul 2009
 

Abstract

In an attempt to produce an animal model of a mycetoma (Madura foot) Madurella mycetomi was inoculated on 3 occasions into a monkey's paw. Groups of mice were inoculated once in the footpad and treated with anti-mouse-lymphocytic serum, cortisone acetate and whole body X-irradiation respectively; half of the groups received the fungus suspended in saline and in half the fungus was emulsified in Freund's adjuvant. An attempt was also made to produce intraperitoneal grains of M. mycetomi in mice.

The monkey developed a transient lesion. The footpad inoculations in the mice caused inflammatory swelling which was severe and persistent in the animals which received the fungus emulsified in Freund's adjuvant but grains were not produced.

Résumé

Au cours d'essais pour définir un modèle animal permettant l'étude des mycétomes (Pied de Madura), Madurella mycetomi a été inoculé à 3 reprises dans la patte d'un singe. Des groupes de souris ont été inoculés une seule fois dans le coussinet plantaire et traités respectivement avec un sérum anti lymphocytes de souris, de l'acétate de cortisone et une irradiation totale aux rayons X; la moitié des animaux de chaque groupe a reçu le champignon en suspension dans l'eau physiologique et l'autre moitié en émulsion dans l'adjuvant de Freund. On a également essayé de provoquer des grains intraperitoneaux à M. mycetomi chez la souris.

Le singe a développé une lésion fugace. Les inoculations dans le coussinet plantaire des souris ont été suivies d'enflure inflammatoire qui était sévère et persistante chez les animaux ayant reçu le champignon et l'adjuvant de Freund mais il n'y a pas eu de production de grains.
