[2][3][4][5] Blochmannia was first discovered by zoologist Friedrich Blochmann in 1887, who described "bacteria-like structures" in the ovaries and midgut of Camponotus ligniperdus in 1887.
[6] Within the midgut, large numbers of Blochmannia are found in bacteriocytes in the gut's epithelial layer.
[10] According to researchers Fan and Wernegreen, this experiment suggests that the Blochmannia in ants could be vulnerable to the effects of global warming.
[10] Endosymbiosis, or when the Blochmannia bacteria and the ant hosts became bonded, occurred around 30–40 million years ago.
[11] The high amounts of genetic conservation suggest that the Blochmannia genes lack some recombination mechanisms.
