Biological Methods for Microbial Control

Biological Methods for Microbial Control

Biological agents offer an effective means of controlling microbial growth by leveraging natural processes like predation, competition, and the secretion of antimicrobial substances.Predatory bacteria such as Bdellovibrio species target and kill pathogens like Salmonella and E. coli. They are widely used in poultry farms to control infections. Myxococcus species help combat plant-pathogenic fungi. These naturally occurring predators serve as eco-friendly alternatives to chemical pesticides and...

To inform the development of effective, large-scale vector control strategies.

Main Methods:

Review of mathematical modeling approaches for Wolbachia spread.
Analysis of population dynamics influenced by Wolbachia.
Examination of theoretical frameworks for transgene introgression via Wolbachia.

Main Results:

Mathematical models are essential for predicting the behavior of released Wolbachia infections.
