A streaker device for streaking a microbial inoculum for single colonies on the surface of a solid growth medium. The streaking device has a row of spaced apart contact surfaces for contact with the surface of the solid growth medium. The spaced apart contact surfaces are resiliently flexibly supported by a common support member so as to accommodate variations in depth of growth medium. The spaced apart contact surfaces may be provided on lowermost part of axially curved portions of plastics straps, that are angled backwardly. It is found that formation of a single band can give separation into single colonies. Also provided is an automatic streaking apparatus.

La présente invention a trait à un dispositif de type peigne pour le peignage d'un inoculum microbien pour des colonies uniques à la surface d'un milieu de culture solide. Le dispositif de peignage comporte une rangée de surface de contact espacées pour le contact avec la surface du milieu de culture solide. Les surfaces de contact espacées sont portées avec un flexibilité élastique par un support commun de manière à s'adapter à des variations de profondeur dans le milieu de culture. Les surfaces de contact espacées peuvent être prévues sur la partie inférieure de portions incurvées de bandes en matière plastique, qui sont inclinées vers l'arrière. On a observé qu'une bande unique peut entraîner la séparation dans des colonies uniques. L'invention a également trait à un appareil de peignage automatique.
