مستخلص: | Meningitis, acute infection of the meninges, is the 10th leading cause of mortality among infectious diseases. Although many different causes for meningitis (viruses and bacteria) have been diagnosed, the most common ones are Neisseria meningitidis, Haemophilus influenzae, and Streptococcus pneumoniae. The effort to find a new method for detection of bacterial meningitis is an urgent need for clinical treatment. DNA aptamers generated by cell-systematic evolution of ligands by exponential enrichment (SELEX) against bacterial cells provide a novel cell labeling and biosensing technique. Here, we isolated single-stranded DNA aptamers during the SELEX method with a high affinity for different bacterial genera. This approach was demonstrated on H. influenzae type B, N. meningitidis serogroups A, B, C, and Y, and Streptococcus pneumoniae serotypes 18, 14, 19A, 6A, and 6B which served as targets in 20 rounds of cell-SELEX. After 20 rounds of SELEX, a total of 93 aptamers were identified. Among these, aptamers C65 and C50 showed the highest affinity toward targets with a dissociation constant of 6.98 and 15.79, respectively. Selected aptamers were able to successfully detect clinical bacterial strains isolated from cerebrospinal fluid samples of meningitis patients by double-aptamer sandwich enzyme-linked oligonucleotide assay (ELONA). Our findings demonstrated that aptamers with broad affinity to bacterial taxa in different genera can be isolated for the development of diagnostic tools for multiple targets. We further showed that sandwich ELONA based on single-stranded DNA aptamer is sensitive and specific enough for detection of the superior cause of bacterial meningitis.
