In a Brief Communication, Meir Broza and Malka Halpern of the University of Haifa, Israel, describe how they were able to isolate non-pathogenic strains of V. cholerae from all the samples of midge eggs. The eggs were collected from waste-stabilization ponds around Israel.
It is thought that the bacterium probably feeds on the gelatin coat surrounding the egg, usually killing it in the process.
|V. cholerae may disperse itself using midge eggs.
The researchers hypothesize that the egg masses may aid the dispersal of pathogenic V. cholerae and allow it to survive between epidemics.
