Paper, 'On the structure and development of the cysticercus cellulosae [pork bladder worm], as found in the muscles of a pig' by George Rainey

Description

Rainey explains that the cysticercus in its developed state is found chiefly in the ordinary muscles lodged in the cellular intervals between the fibres, also on the surface of the muscles immediately beneath their fascial investment. These parasites infest the heart in as great abundance as other muscles composed of striped fibres, where they are situated, some in the substance of the walls of the auricles and ventricles, others directly beneath the pericardium between it and the muscular fibres, and others just under the endocardium. They occur also in the muscular coat of the œsophagus, almost as low down as the stomach. But as in the pig the striped fibres extend nearly to the inferior extremity of this tube, the presence of cysticerci there forms no exception to their usual position in muscles composed of striped fibres. Rainey found very few in the lower part of this tube, and did not observe them in the muscular coat of the intestines, in that of the large vessels close to the heart, in any of the glandular organs, nor in any of the structures of the lungs.
