Background: Urinary tract infections and bacillary dysentery are among the many illnesses that people and animals can get from the varied bacterial species Escherichia coli. Its pathogenic potential is enhanced by the presence of virulence factors and genes resistant to antibiotics in its genome. Mobile genetic elements like plasmids, which promote the horizontal transmission of virulence and resistance characteristics, have an impact on these genes. Its genetic diversity is further shaped by environmental factors, such as interactions within biotic and abiotic niches.

Objectives: With an emphasis on pathogenicity, population structure, and the consequences for antibiotic resistance, this research attempts to investigate the genetic diversity of Escherichia coli. According to genetic study, microbial interactions and environmental factors influence population formations. Meningitis-causing strains and ExPEC are examples of subgroups that display unique genetic lineages that reflect host and niche adaptability. One of the main forces behind genetic variety is horizontal gene transfer, which makes it possible for features that improve pathogenicity and survival to be acquired quickly.

Results: The findings show that E. coli's genetic variety is essential to its capacity for adaptation and evolution. New strains with distinct resistance and virulence traits evolve as a result of the interaction between genetic variation and environmental variables. Nevertheless, this diversity's functional characterisation is still lacking, requiring more investigation.

Conclusion: In conclusion, creating efficient plans to fight illnesses and lessen the worldwide burden of antibiotic resistance requires a knowledge of the genetic variety and population dynamics of E. coli. To meet the problems presented by this versatile and more resistant virus, increased monitoring, molecular typing, and cooperative research are essential.
