Iron and zinc exploitation during bacterial pathogenesis.

Area of Science:

• Microbiology
• Biochemistry
• Evolutionary Biology

Background:

• Ancient bacteria evolved in metal-rich environments, developing metallomes to utilize metal co-factors.
• Metals like iron and zinc are crucial for essential cellular processes, including energy production and DNA replication.
• Pathogenic bacteria face challenges in acquiring essential metals like iron and zinc within a host environment.

Purpose of the Study:
