Sneathia amnii is a poorly characterized gram-negative anaerobe that commonly colonizes the vagina. It has been linked to many obstetric disorders, including preterm labor, preeclampsia, and chorioamnionitis. S. amnii lyses human red blood cells, and we aimed to identify the hemolysin. We identified two genes that appear to encode transporter and effector components of a two-partner secretion system. The putative effector, which we refer to as SaFHA, contains a domain with amino acid similarity to the filamentous hemagglutinin (FHA) of Bordetella pertussis and its predicted structure suggests it may form a transmembrane channel or pore. Thus, we hypothesized that SaFHA …
