Abstract Fungi and bacteria coexist in many polymicrobial communities, yet the molecular basis of their interactions remains poorly understood. Using unbiased genomic approaches, we discover that the fungus Candida albicans sequesters essential Mg2+ ions from the bacterium Pseudomonas aeruginosa. In turn, the bacterium competes using a Mg2+ transporter, MgtA. We show that Mg2+ sequestration by fungi is a general mechanism of antagonism against gram-negative bacteria.

by Deacon Robin Cheung Today we celebrate the 6th Sunday of Easter. We thank God for sending us his peace and the Holy Spirit! There is a lot of coming and going in life. Everyday we have to make many decisions. How can we make a peaceful choice? Prayers definitely can help. Speaking of decisions, last week, my wife and I had to change our plans. We were planning to visit Ottawa on Saturday with our son’s family to admire the blooming of the tulips.
