The present invention relates to a method for enhancing the time of response of an assay for a first bacterium, wherein: a) the first bacterium is exposed to infection by phage particles to which the first bacterium is permissive; b) the infected bacterium is treated to inactivate exogenous phage particles; c) the treated bacterium is cultivated in the presence of a second bacterium which is permissive to infection by the phage or its replicand and which has a doubling rate greater than the effective doubling rate of the first bacterium; and d) assessing the extent of plaque formation and / or of second bacterium growth in the cultivated second bacterium cells. The method can be used to assess the presence of first bacterium in a sample, notably where the first bacterium is a slow growing bacterium, such as Mycobacterium tuberculosis, where the method enables an operator to detect the presence of low amounts of the bacterium in sample within days instead of weeks as required by conventional cultivation techniques. The invention can also be used to assess the effect of a drug or other treatment on a bacterium or on a virus. The invention also provides a diagnostic kit for use in the method of the invention.
