Wolbachia is a genus of rickettsial organisms, a microorganism positioned somewhere between viruses and true bacteria. Like viruses, they grow only in living cells, but like bacteria, they are vulnerable to antibiotics.
Within the bacteria, a large subset called the "true bacteria" includes most of the medically significant species.
True bacteria can exist as single cells, as clusters of cells, or as chains that are either branched or straight, a fact used by scientists in classifying the bacterial world.
