Helminths of South Dakota Coyotes
From September 1976 through January 1978, 343 coyotes (Canis latrans) carcasses were obtained for this study from South Dakota Department of Game, Fish and Parks trappers and from fur buyers. Coyotes were necropsied, internal organs were examined for helminth parasites, and parasites located were …

Some helminths from salamanders of California
… and Dicamptodon ensatus (1), were examined for helminths and found to harbor 10 species, four of which are new. The parasites found are: Cestoda: Distoichometra ensatinae sp. nov. from Ensatina e. eschscholtzii and E. e. sierrae; and Baerietta diana (Helfer, 1948) Douglas, 1958 from Batrachoceps …

Development of vaccines against allergic asthma using products derived from intracellular bacteria or helminths
Die „Hygiene Hypothese“ postuliert, dass der Kontakt mit Infektionserregern in der frühen Kindheit die Entwicklung von Th2-abhängigen allergischen Immunreaktionen verhindern kann, indem dadurch entweder eine vorrangig Th1-gerichtete Immunität etabliert wird oder alternativ die Bildung von …

Development and application of genomic tools for characterising genetic variation in soil-transmitted helminths
Soil-transmitted helminths (STHs) are intestinal parasitic worms that represent a significant global health challenge, perpetuating poverty and disease. For decades, the diagnosis of STHs has depended on the microscopic detection and identification of eggs or larvae in faecal samples. However, …

Investigations into the use of continuous low-level medication for the control of helminths in the ruminant
The work presented in this thesis is concerned with the chemotherapy of parasite infestations in the ruminant with the anthelmintic thiophanate [diethyl 4,4'-o-phenylene bis (3-thioallophanate)]. A new concept of administration was investigated, namely continuous low-level anthelmintic medication. …

Exploring the impact of gastrointestinal parasitic helminths on the human microbiome using advanced biomolecular and bioinformatics technologies
… biology of human gastrointestinal (GI) parasitic helminths is greater than ever before. However, so far, the research has focused on gene expression profiling, immune- and protein-protein interactions in host-parasite systems. The importance of parasite microbiota interactions has, so far, been …

Soil-Transmitted Helminths Surveillance in Benin: A Mixed-Methods Analysis of Factors influencing Participation in Longitudinal STH Surveillance Activities
… of interrupting transmission of soil-transmitted helminths (STH) via intensive approaches to deworming, including community-wide mass drug administration (MDA). Transitioning from a policy of STH control to transmission interruption will require rethinking existing STH surveillance protocols. …

Estudo qualitativo e quantitativo da helmintofauna dos peixes Scomberomorus cavalla (Cuvier) e Scomberomorus maculatus (Mit-Chill) no litoral do Ceará, Brasil
… qualitative and quantitative analysis of the helminths parasites of Scomberomorus cavalla (Cuv.) e Scomberomorus maculatus (Mitch.) in Ceará Coast. Based on earlier on the host species in Ceará, the author adds biological data also refering to these species. It is shown through tables and …

Helminth infections of the European eel Anguilla Anguilla in the United Kingdom
… eels (72.1 %) were infected with a total of 1504 helminths and these included gill monogeneans (prevalence = 35.7%), gastrointestinal nematodes (prevalence = 33.6%), the swim bladder nematode Anguillicoloides crassus (prevalence = 25.0%), acanthocephalans (prevalence = 30.0%) and cestodes …

An exploration of parasite-microbiota interactions in the ruminant gastrointestinal tract and insights into the antibacterial role of helminth excretory-secretory products
Gastrointestinal (GI) helminths are amongst the most important infectious agents affecting the welfare and health of livestock animals worldwide. GI helminths are known to interact with the host *via* several complex mechanisms, that include modulation of the host immune system and of the commensal …

The helminthfauna of the beaver in western Maryland
… record any evidence of gross pathology involving helminths. A sample of 63 beaver, 31 males and 32 females, was obtained from Garrett, Alleghany, and Washington Counties in Maryland through fur sealing stations and the University of Maryland Natural Resources Institute at LaVale. Five helminths …

The Seasonality and Parasite Richness and Prevalence of the Weddelli’s Saddleback Tamarin (Leontocebus Weddelli)
<p>This study surveyed the intestinal helminths (parasitic worms) of Weddelli’s saddleback tamarins (<em>Leontocebus weddelli</em>), focusing on seasonality in parasite prevalence and richness. The collaborative study with Field Projects International took place at the Estación Biológica Rio Los …

The Search for Novel Anthelmintic Targets: Characterizing Alternative Metabolic Pathways in Caenorhabditis elegans
… of the human population is infected by parasitic helminths which also infect and place a large economic burden on the agricultural industry. Unfortunately anthelmintic resistance is a growing problem. Helminths survive long periods of low to no oxygen in their hosts, but their anaerobic metabolism …

SCALE-DEPENDENT VARIATION IN MOLECULAR AND ECOLOGICAL PATTERNS OF INFECTION FOR ENDOHELMINTHS FROM CENTRARCHID FISHES
… the intraspecific molecular variability of helminths in a widely distributed freshwater fish host. Equally rare are studies considering both large- and small-scale patterns of infection of helminth communities in a widely distributed aquatic host(s). Vanishingly few studies exist making …
