Activation of bacterial cytochrome P450 in the intestine of larval mosquitoes an indication of its role in the insecticide resistance

Abstract EN

Mosquitoes apply very important impact on people life, and their control, day by day, is getting harder and harder.

This difficulty comes from different issues such as insecticide resistance.

The gut microbiome (GM) in different animals has been discovered to add principle influence on the gastrointestinal tract physiology.

For example, GM participates in degradation of some poisonus chemicals into safer molecules that could be handled by the animal host.

Eukaryotic cytochrome P450 has been detected to inseret some degradation processes in other animal models such as zebra fish.

However, these effects are not yet known in mosquitos.

In order to stand on these problems and find if the prokaryotic P450 is involved, this study had been done to find out if the GM has any role in developing such resistance in mosquitos.

Larvae were used in this experiment which exposed to benzothiozole (BZT) to trigger the hypothetical role of prokaryotic P450.

By using polymerase chain reaction (PCR), the result indicates that the bacterial P450 was initiated and might be involved in the BZT exposure handling.
