HOBERG, J. R. LlCHTENFELS, AND P. A. PlLITT United States Department of Agriculture, Agricultural Research Service, Biosystematic Parasitology Laboratory, BARC East, Building 1180, 10300 Baltimore Avenue, Beltsville, Maryland 20705 ABSTRACT: The synlophe of Cooperia neitzi is characterized by a closed pattern in the cervical region (most similar to C. punctata and C. pectinatd), a minuscule lateralmost ridge, 20 ridges at the level of the excretory pore and cervical papillae in males and females, and sequential addition of ridges laterally starting near the midbody (20 and 24 ridges at the midbody of males and females, respectively, with a maximum of approximately 32 adjacent to the copulatory bursa and vulva). The characteristic bilateral vulval fan in females has a consistent structure, being supported by a pair of hypertrophied ridges in each subdorsal field adjacent to the lateralmost ridge. Three species typical of bovids in sub-Saharan Africa (C. neitzi, C. verrucosa, and C. okapi) share the characters of minuscule lateralmost ridges, a closed cervical synlophe, and cuticular inflations at the level of vulva. Comparisons to other species of Cooperiinae (Parostertagia heterospiculum, Cooperia verrucosa, and Cooperia okapi) indicate homology in the bilateral and symmetrical structure of the vulval fans recognized in species of the subfamily. In contrast, it appears that the irregular and asymmetrical cuticular inflations reported or observed at the level of the vulva among certain Ostertagiinae (Longistrongylus spp., Mazamastrongylus spp., and Camelostrongylus mentulatus) have a fundamentally different configuration. It is suggested that vulval inflations in the Cooperiinae and Ostertagiinae had independent origins and thus are convergent.

I study their taxonomy using traditional microscopic and histological techniques and their genetic interrelationships and systematics using ribosomal DNA sequences. I also investigate the effects of extrinsic factors on aquatic environments by using parasite prevalence and abundance as a proxy for total biodiversity in aquatic communities and for assessing food web dynamics. I am also interested in the epidemiology of viral diseases of crustaceans.

  • Somatic Musculature in Trematode Hermaphroditic Generation Darya Y
    Krupenko and Dobrovolskij BMC Evolutionary Biology (2015) 15:189 DOI 10.1186/s12862-015-0468-0 RESEARCH ARTICLE Open Access Somatic musculature in trematode hermaphroditic generation Darya Y. Krupenko1* and Andrej A. Dobrovolskij1,2 Abstract Background: The somatic musculature in trematode hermaphroditic generation (cercariae, metacercariae and adult) is presumed to comprise uniform layers of circular, longitudinal and diagonal muscle fibers of the body wall, and internal dorsoventral muscle fibers. Meanwhile, specific data are few, and there has been no analysis taking the trunk axial differentiation and regionalization into account. Yet presence of the ventral sucker (= acetabulum) morphologically divides the digenean trunk into two regions: preacetabular and postacetabular. The functional differentiation of these two regions is already evident in the nervous system organization, and the goal of our research was to investigate the somatic musculature from the same point of view. Results: Somatic musculature of ten trematode species was studied with use of fluorescent-labelled phalloidin and confocal microscopy. The body wall of examined species included three main muscle layers (of circular, longitudinal and diagonal fibers), and most of the species had them distinctly better developed in the preacetabuler region. In majority of the species several (up to seven) additional groups of muscle fibers were found within the body wall. Among them the anterioradial, posterioradial, anteriolateral muscle fibers, and U-shaped muscle sets were most abundant. These groups were located on the ventral surface, and associated with the ventral sucker. The additional internal musculature was quite diverse as well, and included up to twelve separate groups of muscle fibers or bundles in one species.
