Marcelo Jacobs-Lorena, a geneticist at Johns Hopkins University in Baltimore, Maryland commented on study saying that initial results are promising. However, Lorena is t part of study.  organisation reported that in Townsville, Australia, where bacteria were injected four years ago, reported only four cases of dengue and hence a tremendous decrease from previous count of 69. bacteria Wolbachia is naturally found as a parasite in various insects.
