Application of chemical sensors to the rapid assessment of the digestive tract of birds

Resumo

The application of a piezosensor array to the assessment of the conditions of the digestive tract of birds by the presence and concentrations of dysbiosis markers in the equilibrium gas phase over the biosamples is discussed. A dysbiosis index is proposed for the rapid screening diagnosis of the dysbiosis status of intestines, calculated by the output data of the sensor array. The results obtained with chemical sensors are consistent with the data of microbiological studies. The method is very useful in monitoring the dynamics of variation of the dysbiosis index.
