In tight spaces, bacteria make a break for it ...

Bacteries alter their swimming patterns when they get into tight spaces, putting a beeline to escape confinement, according to a recent study by scientists at the University of Hawaii at Manoa.

Nearly all organisms have bacteria that live symbiotically on or inside their bodies. The Hawaiian bobtail bacterium Vibrio fischeri, which has a whip-like tail, which it uses to swim to specific places in the squids body.

The group, led by Jonathan Lynch, who served as a postdoctoral researcher at the Pacific Biosciences Research Center (PRC) at the University of Hawaii''s Manoa School of Ocean and Earth Science and Technology (SOEST), developed controlled chambers in which the bacteria could observe the Vibrio bacteria swimming. Using microscopy, the team discovered that as the bacteria moved between open areas and tight spaces, they swim differently.

Bactiles appeared to meddle with no apparent pattern-changing direction randomly and at different times in time Upon arrival in restricted areas, they decided to follow their swimming paths to avoid confinement.

According to Lynch, the current head of the University of California, Los Angeles, has found out what happened when bacterial cells moved into tight spaces. After looking at more closely, we discovered that the bacteria were actively swimming out of tight spaces. This was not the case for the bacteria.

Despite the fact that these physical features are found in many bacteria-animal relationships, bacteria live with other animals, such as the human microbiome. Microbes often traverse complicated routes, sometimes squeezing through tight areas in tissues. However, less is known about how physical features like walls, corners, and tight spaces affect bacteria''s swimming.

According to Lynch, tight spaces may serve as an additional, crucial guide for bacteria when they enter certain habitats. Changing swimming patterns in tight spaces may allow some bacteria to quickly swim through the tight spaces to reach the other side, but for others, they turn around before the get stuckkind of like choosing whether to run over a broken bridge or turn around before you go too far.

The researchers hope to research how these bacteria are controlling their swimming activity in the future, as well as whether other bacteria demonstrate the same characteristics.
