Provided are devices, for testing a sample for a specific microorganism, including specific embodiments for determining presence of group B streptococcus, comprising: a first reservoir containing a selective broth and a second reservoir containing a selective agar comprising an indicator moiety, the selectivity being for the specific microorganism, and the indicator moiety being associated with a measurable property change in the presence of the specific microorganism or attribute; and a conduit fluidically connecting the two reservoirs, the conduit having a valve, having an open position and a closed position initially positioned in the closed position. The sample is introduced into the first reservoir and the device is incubated at a first specified temperature for a first incubation period. The valve is then opened to introduce the contents of the first reservoir into the second reservoir and the device is then incubated at a specified temperature for a second incubation period (Figure 1). |
