Motile bacteria presented simultaneously with both attractant and repellent respond to whichever one is present in the more effective concentration. Apparently bacteria have a processing mechanism that compares opposing signals from the chemoreceptors for positive and negative taxis, sums these signals up, and then communicates the sum to the flagella. 
Data processing by the chemotaxis machinery of Escherichia coli
TLDR
The properties of che mutants are summarized and a model of the chemotaxis machinery is derived based on this genetic analysis of nonchemotactic mutants of the type first described in E. coli by Armstrong et al.7. Expand
Bacterial Chemosensing
Bacteria have a continuous and urgent need to inform themselves about the chemistry of their surroundings. They must rapidly adjust their patterns of gene expression, their metabolic and transportExpand
Bacterial chemotaxis as a simple model for a sensory system
Abstract Bacteria have a rudimentary memory and a system for interpreting responses to positive and negative stimuli. The biochemical pathways of this system may have close analogies to theExpand
Sensory Response in Bacteria
TLDR
Bacterial behavior, therefore, is a phenomenon that has many analogies to more complex behavior patterns but is contained in an extremely small living cell. Expand
Pattern Formation On a Negative Relation between Bacterial Taxis and Turing
In this paper we introduce a bacteria-leukocyte model with bacteria chemotaxsis. We assume that bacteria develop a tactic defence mechanism as a response to Leukocyte phagocytosis. We explore theExpand
On a Negative Relation between Bacterial Taxis and Turing Pattern Formation
TLDR
A fine tuning of bacterial chemotaxis shows a significant effect on developing a non-uniform steady state and the effect of this tactic motion on Turing space in two parameter spaces is explored. Expand

The present review will restrict itself to the recent work on chemotaxis in Escherichia coli and Salmonella typhimurium. Expand
Responses of Escherichia coli Bacteria to Two Opposing Chemoattractant Gradients Depend on the Chemoreceptor Ratio
TLDR
Using a recently developed microfluidic chemotaxis device, E. coli cells are exposed to two opposing but equally potent gradients of major attractants, methyl-aspartate and serine, and responses demonstrate the importance of the cellular microenvironment in determining phenotypic behavior. Expand
Sensory adaptation mutants of E. coli
TLDR
The ability of E. coli to adapt to constant levels of attractant and repellent chemicals was studied by examining the patterns of flagellar movement in cells subjected to abrupt concentration changes, and possible mechanisms of stimulus transduction and sensory adaptation during chemotaxis are discussed.

Biphasic Excitation by Leucine in Escherichia coli Chemotaxis
TLDR
Wild-type E. coli bacteria were attracted in spatial assays when the initial leucine concentration difference was 5 to 120 micro M but were repulsed when it was over 0.5 mM, confirming earlier deductions regarding biphasic excitation. Expand
