Discovery of Taeniid Eggs from A 17th Century Tomb in Korea

Even though Taenia spp. eggs are occasionally discovered from archeological remains around the world, these eggs have never been discovered in ancient samples from Korea. When we attempted to re-examine the archeological samples maintained in our collection, the eggs of Taenia spp., 5 in total number, were recovered from a tomb of Gongju-si. The eggs had radially striated embryophore, and 37.5-40.0 micromx37.5 microm in size. This is the first report on taeniid eggs from ancient samples of Korea, and it is suggested that intensive examination of voluminous archeological samples should be needed for identification of Taenia spp.

Studies on abnormality of metacestodes and adult worms of Taenia solium and Taenia saginata asiatica in rodents and pigs.

Abnormalities are not uncommon in Taenia saginata and T. solium. After examining 328 mature proglottids from 2 adult worms from two experimentally infected hamsters, 13 (4.0%) were found to have no genital pore but with numerous testes and several vas efferents; 1 (0.3%) one genital pore with one reproductive system; 12 (3.7%) one on each side with two sets of reproductive system; 17 (5.2%) two on one side with 2 sets of reproductive system; 8 (2.4%) one on one side and two on the other side with 3 sets of reproductive system; 2 (0.6%) two on each side with 4 sets of reproductive system; 4 (1.2%) three on one side with 3 sets of reproductive system, and 4 one on one side and three on the other side with 4 sets of reproductive system. Nine evaginated abnormal cysticerci of T. s. asiatica from three experimentally infected SCID mice each had two protoscoleces and a big bladder. From two experimentally infected pigs, one abnormal cysticercus was observed to have two invaginated canals each in one end. Another one had a neck-band behind the scolex and a big bladder. This paper is not only the first report of abnormality of T. solium from hamster but also the first one of abnormal cysticerci of T. s. asiatica from pigs and mice.

Microphallus fonti sp. n. (Digenea: Microphaliidae) from the red swamp crawfish in southern United States

A new species of digenean, Microphallus fonti, is described from the red swamp crawfish in Lousiania, U.S.A. It has a small pharynx and a rudimentary gut like M. opacus and a possibly related species from crayfishes, but it differs from them by its relatively large male copulatory papilla and a conspicuous metraterm

Pruebas morfológicas de que C. cellulose y C. racemosus son larvas de Taenia solium / Morphological evidence indicating that C. cellulosae and C. racemosus are larval stages of Taenia solium

La finalidad de este estudio fue demostrar que el cisticerco racemoso (CR) es, como el celulosos (CC), larva (metacestodo) de T. solium, hecho que se ha puesto en duda. CR sólo parasita el cerebro del hombre, en donde causa las formas más graves de cisticercosis cerebral. Para lograr este propósito se buscaron restos del escólex y los ganchos del rostelo en dos CR y en cuatro cisticercos de forma intermedia (CFI) que se extrajeron quirúrgicamente de los ventrículos cerebrales. Los CFI son parásitos que comparten características morfológicas y con CC y CR, ya que poseen gran desarrollo de la membrana pero conservan estructuras que aparentemente corresponden al escólex. Se hicieron corte histológicos seriados y observaciones con microscopios estereoscópico y electrónico de barrido. En CR fue posible localizar la corona de ganchos, y en los CFI las estructuras del escólex: conducto espiral, ventosas y ganchos. Se concluye que CC, CR y CFI son formas larvarias de T. solium
