Phylogenetic Comparison of Endosymbionts with Their Host Ants Based on Molecular Evidence (1999)

Shinya Sameshima, Eisuke Hasegawa, Osamu Kitade, Nobuhiro Minaka, Tadao Matsumoto

Some Formicid ants have symbiotic intracellular bacteria in the epithelial cells of their midgut. These endosymbionts are believed to be derived from a common ancestor. A recent study revealed that...

Novel Clade of Rickettsia spp. from Leeches

Kikuchi, Yoshitomo, Sameshima, Shinya, Kitade, Osamu, Kojima, Junichi, Fukatsu, Takema

Intracellular rickettsia-like structures were found in the tissues of a glossiphoniid leech, Torix tagoi, by transmission electron microscopy. Diagnostic PCR analysis using specific primers suggested...
