“…It is restricted to cyclophyllideans (some members of the families Taeniidae, Hymenolepididae and Dilepididae), a few unidentified pseudophyllideans (Nobrega-Lee et al 2007) and to the Mesocestoididae. The position of the latter family in the order Cyclophyllidea has been questioned by proposing the division of the latter order into two groups: "mesocestoidatans + cyclophyllideans" (Mariaux 1998).…”

Post-embryonic development and fully-formed polycephalic larvae of Taenia parva Baer, 1926 were examined by light (LM) and transmission electron microscopy (TEM). Three developmental stages were recognised: (1) an early stage of exogenous budding at the surface of the central vesicle; (2) a stage of polycephalic cyst development accompanied by segmentation of the growing larval strobile and an obvious decrease in the size of the central vesicle; (3) fully-formed larval strobile and invaginated scoleces. In fully-developed encysted polycephalic larvae, there are usually 14-24 segmented larval strobilae, each terminating with an invaginated scolex; larval strobilae arise from a common central vesicle and remain attached posterior to it during the entire development. The number of segments varies between 109 and 120 per larval strobila. The polycephalic larvae examined closely resemble the strobilocercus type of taeniid larvae. The structure of developing and fully-formed larvae was examined by TEM. The tegument, scolex, subtegumental musculature of the strobilar segments, protonephridial system, calcareous corpuscles and medullary parenchyma of larvae exhibit general similarity with the same structures in adults at both LM and TEM levels. The morphogenesis of the larva of T. parva is compared with that of the polycephalic larvae of other Taenia spp. (T. krepkogorski, T. twitchelli and T. endothoracica) and with other asexually-multiplying cestode larvae (mesocestoidids, hymenolepidids and dilepidids).

“…Brightfield histological section of an otherwise normal tetrathyridium, showing details of the anomalous branching tegumental pits (Tp) and the anomalous extension of an excretory duct (D). Note that the two anomalous structures do not share a common lumen the cases could actually be proliferative spargana Nobrega-Lee et al 2007). Further detailed examination of tetrathyridia from various hosts around the world should be undertaken to seek other examples of these and other forms of asexual proliferation, as well as other anomalies.…”

“…The most frequently reported of the asexual forms have been identified as aberrant tetrathyridia of the genus Mesocestoides (Ssolonitzin 1933;Conn 1990;Wirtherle et al 2007) and proliferating diphyllobothriid plerocercoids from various hosts, probably an aberrant form of Spirometra sp. (Kuntz et al 1970;McFarlane et al 1994;Beveridge et al 1998;Nobrega-Lee et al 2007); the latter includes the rare human parasite Sparganum proliferum (Noya et al 1992). Both aberrant tetrathyridia and plerocercoids reproduce asexually by multiple budding and fission of the hindbody.…”

Interactions between anomalous excretory and tegumental epithelia in aberrant Mesocestoides tetrathyridia from Apodemus sylvaticus in Spain

Tetrathyridia of Mesocestoides sp. (Platyhelminthes: Cestoda) were collected from the body cavities of Apodemus sylvaticus (Rodentia: Muridae) in Murcia, Spain, and processed by routine microscopical and histological techniques, including examination with brightfield, phase-contrast, and differential-interference-contrast optics. All specimens examined had solid hindbodies (i.e., lacked a primary lacuna), thus conforming to the plerocercoid metacestode type. The vast majority of tetrathyridia were highly aberrant, often lacking a scolex, varying greatly in body size, and exhibiting buds or duplexed body forms indicative of asexual proliferation. All of the aberrant forms, including those with normal scoleces and apparent absence of proliferation, possessed anomalous multi-lobed invaginations of the hindbody tegument, which were attached at many points to abnormally dilated excretory ducts. The tegumental and excretory epithelia were joined basally, but did not share a common lumen. These abnormal connections between these aberrant tegumental modifications and the abnormally dilated excretory ducts have not been described previously for any metacestode. This report contributes to understanding previously published reports of abnormalities in other plerocercoid metacestodes, including Mesocestoides spp. and diphyllobothriidean spargana.

Sparganosis in wild‐caught baboons (Papio cynocephalus anubis)

Abstract: Based on the results that have been obtained, sparganosis did not appear to affect the endocrinological profile of pregnant and cycling female baboons.
