Bacterial colonization of the intestine has been proven by the Cell and Developmental Biology (Bosch AG) research team to play a vital part in the control of peristaltic functions. The scientists at the Zoological Institute at Kiel University (CAU) have recently published the results in the latest edition of Scientific Reports. The results have been derived using the example of freshwater polyps Hydra. Collaborative Research Centre (CRC) 1182 Origin and Function of Metaorganisms spokesperson and study head, Prof. Thomas Bosch has said that the contractions of the organism’s digestive cavity could be affected by bacterial colonization. According to Bosch, this could take place with the modulation of the underlying pacemaker signals.

Bacterial Signals decisively affect Pattern of Spontaneous Peristaltic Contractions

Normal Hydra with typical bacterial colonization had been compared with those that were denied of the presence of any microbiome through complete removal using an antibiotic cocktail. Relatively, the organisms without bacterial colonization, a.k.a. germ-free polyps, demonstrated a reduction in contractions by nearly half. Peristaltic movements in Hydra had been found to be compromised in body cavity due to the absence of a typical microbiome.

Going forward, the germ-free organisms had been restored with specific bacterial colonization. However, as it turned out, individual bacterial colonization had no considerable effect on the timing and frequency of contractions. Nevertheless, a marked improvement in peristalsis had been observed only when the five main representatives of the microbiome were jointly reintroduced.

Bosch had summarized that the emergence of severe diseases arising from disrupted movement of the intestine could be understood with the important elucidation of the cooperation between microbiome and organism in the regulation of peristalsis.
