WOLBACHIA METHOD - SCI & TECH

News: Wolbachia: An unlikely hero

 

What's in the news?

       Wolbachia is a genus of bacteria that has evolved complex relationships with the many insects that can host it.

       It is named for the American pathologist Simeon Burt Wolbach, who identified it along with Marshall Hertig in 1924.

 

Wolbachia:

       Wolbachia is a type of intracellular bacteria that infects a wide range of arthropods, including insects and other invertebrates.

       It has garnered significant attention in recent years due to its intriguing biological properties and potential applications in various fields.

 

Features:

       Wolbachia are natural bacteria present in up to 60% of insect species, including some mosquitoes.

       However, Wolbachia is not usually found in the Aedes aegypti mosquito, the primary species responsible for transmitting human viruses such as Zika, dengue, chikungunya and yellow fever.

       Wolbachia is safe for humans, animals and the environment.

       The bacteria Wolbachia “inhibits” viral infection, that is, even if people encounter mosquito bite, they will not be infected. This happens because bacteria does not allow the virus to replicate in the mosquito thereby minimizing its number within the mosquito.

 

Host Range:

       Wolbachia infects a diverse array of hosts, including insects like mosquitoes, ants, and butterflies, as well as some nematode species.

 

Applications and Research:

1. Vector Control:

       Scientists are investigating the use of Wolbachia-infected mosquitoes to control the spread of diseases like malaria and dengue fever.

       These mosquitoes, when released into the wild, can disrupt the breeding patterns of disease-carrying mosquito populations.

2. Biocontrol Agent:

       Wolbachia is being explored as a potential biocontrol agent to manage agricultural pests.

       By manipulating the reproductive capabilities of pest insects, it could offer an environmentally friendly solution to pest management.
