including Wolbachia, which may be exploited for pest management. Or, the bugs'pheromones, which tell them where to go
In addition the harmful bacteria known as Î-Proteobacteria decreased in the breast milk-fed babies who received B. infantis.
and B. lactis did not experience a decline in the Î-Proteobacteria which typically increases at the onset of NEC and can cause serious tissue-damaging infections in the gastrointestinal system lungs and other organs of the body.
When infected with the bacteria Wolbachia mosquitoes are unable to spread viruses such as dengue a disease
Now Professor Hoffmann from the University of Melbourne and Professor Michale Turelli from the University of California have shown that by introducing an insecticide resistance gene alongside the Wolbachia bacteria into the mosquito that the insects pass on the disease-blocking bacteria to other mosquitoes faster.
Our results show that Wolbachia-based strategies could hold the key to a cheap and sustainable approach to disease control Professor Hoffmann said.
Wolbachia bacteria strains live naturally inside up to 70%of all insects and are known to protect them against viral infection.
The disease-blocking strain of Wolbachia was discovered first in Australian fruit flies in 1988 by Prof Hoffmann
and trials with collaborators at Monash and James Cook Universities in 2011 showed that Wolbachia-infected mosquitoes were unable to spread the dengue virus.
The approach taken in this new work involves adding a pesticide resistance gene to a newer strain of Wolbachia called wmelpop
and malaria-prone regions and so this strategy should select for the survival of only the Wolbachia-infected mosquitoes
because a Wolbachia-infected female with a resistance gene will always pass on both the gene and the bacteria to her offspring.
Dominating the bacterial communities were a core microbiome of taxa including Actinobacteria Alpha-Beta-and Gamma-proteobacteria and Sphingobacteria.
Just as on human skin many of the bacteria on tropical tree leaves were Actinobacteria and Proteobacteria.
