We present a mathematical model for the motion of a bacterial population in prescribed attractant or repellent gradients. The model is suggested by the observations of Mesibov et al. (1973, J. Gen. Physiol. 62:203) and Brown and Berg (1974, Proc. Natl. Acad. Sci. U.S.A. 71:1388) who found that the sensitivity of the chemotactic response depends on the concentration of attractant. Predictions of the theory are in general agreement with the experiments of Dahlquist et al. (1972, Nat. New Biol. 236:120) and of Mesibov et al. on populations of motile bacteria in fixed attractant gradients. Additional tests of the model are proposed.
我们提出了一个数学模型,用于描述细菌群体在规定的引诱剂或驱避剂梯度中的运动。该模型是基于梅西博夫等人(1973年,《普通生理学杂志》62:203)以及布朗和伯格(1974年,《美国国家科学院院刊》71:1388)的观察结果提出的,他们发现趋化反应的敏感性取决于引诱剂的浓度。该理论的预测结果与达尔奎斯特等人(1972年,《自然新生物学》236:120)以及梅西博夫等人关于固定引诱剂梯度中运动细菌群体的实验结果总体一致。我们还提出了对该模型的进一步测试。
