Background Several non-chlamydial microbial pathogens are associated with clinical signs of active trachoma in trachoma-endemic communities with a low prevalence of ocular Chlamydia trachomatis (Ct) infection. In the Solomon Islands, the prevalence of Ct among children is low despite the prevalence of active trachoma being moderate. We therefore set out to investigate whether active trachoma was associated with a common non-chlamydial infection or with a dominant polymicrobial community dysbiosis in the Solomon Islands. Methods We studied DNA from conjunctival swabs collected from 257 Solomon Islanders with active trachoma and matched controls. Droplet digital PCR was used to test for pathogens suspected to be able to induce follicular conjunctivitis. Polymicrobial community diversity and composition were studied by sequencing of hypervariable regions of the 16S ribosomal ribonucleic acid gene in a subset of 54 cases and 53 controls. Results Although Ct was associated with active trachoma, the number of infections was low (cases: 3.9%, controls: 0.4%). Estimated prevalence (cases, controls) of each non-chlamydial infection was as follows: S. aureus (1.9%, 1.9%), Adenoviridae (1.2%, 1.2%), coagulase-negative Staphylococcus (5.8%, 4.3%), H. influenzae (7.4%, 11.7%), M. catarrhalis (2.3%, 4.7%) and S. pneumoniae (7.0%, 6.2%). There was no statistically significant association between clinical signs of trachoma and presence or load of any of the non-Ct infections that were assayed. Inter-individual variations in the conjunctival microbiome were characterised by differences in the levels of Corynebacterium, Proprionibacterium, Helicobacter and Paracoccus, but diversity and relative abundance of these specific genera did not differ significantly between cases and controls. Discussion It is unlikely that the prevalent trachoma-like follicular conjunctivitis in the Solomon Islands has a dominant bacterial aetiology. Before implementing community-wide azithromycin distribution for trachoma, policy makers should consider that clinical signs of trachoma can be observed in the absence of any detectable azithromycin-susceptible organism.
