Why the study?
Laboratories must transition from cell-culture virus isolation to culture-independent methods to reduce the risk of growing live polioviruses in a soon-to-be polio-free world.
Does direct RNA extraction combined with real-time RT-PCR improve the detection of poliovirus in stool samples from AFP cases compared to cell culture?
Does direct RNA extraction combined with real-time RT-PCR improve the detection of poliovirus in stool samples from AFP cases compared to cell culture?
Culture-independent methods like direct RNA extraction and RT-PCR can safely and quickly screen for polioviruses without the risks of growing live viruses.
Successfully identifying poliovirus from acute flaccid paralysis (AFP) cases is a vital role of the Global Polio Laboratory Network to achieve the goals of the Global Polio Eradication Initiative. Currently, laboratory surveillance relies on virus isolation by cell culture to test for PV present in stool samples. Although this method can identify polioviruses, laboratories must switch to culture-independent methods to reduce the risk associated with growing live viruses in a soon-to-be polio-free world. By implementing this streamlined method, in combination with real-time RT-PCR, laboratories can quickly screen for and type polioviruses of programmatic importance to support the final stages of global polio eradication.
