The first infection due to T.multiceps. In 1913 a locksmith in Paris was suffering from convulsions and aphasia, loss of ability to speak or understand speech. During his autopsy, two coenuri (probably T.multiceps) were found in the brain, one being degenerate and the other containing 75 scolices (knoblike anterior end of a tapeworm that has suckers).
The first infection due to T. serialis. The first proven case of human coenurosis due to T. serialis was reported in a 59 year old French woman by Bonna and collegues in 1933. The coenurus from this patient was fed to a dog and seven characteristic scolices were obtained. The first infection in the Western Hemisphere was reported in 1950 in a two year old California boy.
The first infection due to T. brauni. T. brauni is thought to cause the African form of coenurosis. The first patient suffering from coenurosis caused by T. brauni was reported by Fain and colleagues in 1956.
The first infection due to T. glomerata. First infection found in Nigeria by Turner in Leiper in 1919.
