AbiG was discovered in 1996 on the plasmid pCI750 of *Lactococcus lactis* :ref{doi=10.1128/aem.62.9.3075-3082.1996}.
AbiG 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}. AbiG is classified as abortive infection in :ref{doi=10.1016/j.mib.2023.102312}.
AbiG is composed of two genes AbiGi and AbiGii.
