New research into this microscopic turf war found that bacteria can speed up by using fluid pockets that are shaped by nearby yeast cells. Hitching a ride with these moisture trails allows the bacteria to spread faster and swim further. Pseudomonas aeruginosa (small rod-shaped bacteria) swarms toward and around a neighboring Cryptococcus neoformans (round yeast) colony. Pseudomonas aeruginosa (small rod-shaped bacteria) swarms toward and around a neighboring Cryptococcus neoformans (round yeast) colony. The bacteria cultured with yeast spread up to 14.5 times faster than when it was cultured alone.
