 # AbiO
+
+## Description
+
+AbiO is a single gene defense system discovered in 1998 :ref{doi=10.3168/jds.S0022-0302(98)75713-3}.
+
+AbiO is one of the so-called "Abi" systems for "Abortive infection" discovered in the 90's in research related to the dairy industry :ref{doi=10.1016/j.mib.2005.06.006}. Even though, their name corresponds to an abortive infection, their mechanism of action does not necessarily correspond to an abortive infection. AbiO is classified as a possible Abortive infection in :ref{doi=10.1016/j.mib.2023.102312}.
+
+
+This system is only composed of one single gene containing a helicase domain.
+
+## Molecular mechanism
+
+As far as we are aware, the molecular mechanism is unknown.
+
 ## Example of genomic structure
 
 The AbiO is composed of 1 protein: AbiO.
