Endoparasites of working donkeys in Ethiopia: epidemiological study and mathematical modelling
A mathematical approach was used to model seasonal variation of cyathostomin faecal egg output, and in simulating anthelmintic control strategy. The model is based on parameters of biological development of cyathostomins and climatic data. A good fit of the model prediction to the field data was …

Bats and their endoparasites : characterising pipistrelle infections and toll-like receptor (TLR2 and TLR4) gene variations
… thesis highlights the difficulty of studying bat endoparasites and this is often confounded by the lack, or absence, of parasitic material to assist developing molecular-based tools. Despite this difficulty, interesting data have been generated with respect to the pipistrelle genetics, including …

The Hitchhiker's Guide to the Host: Fleas and the History of Pikas in North America
… host a diverse parasite community comprising endoparasites (e.g., coccidians, nematodes, and cestodes) and ectoparasites (e.g., fleas and mites). Phylogenetic analysis of pika endoparasites has revealed pikas evolved in Asia and colonized North America in two waves, and that contact between …

FLEAS OF THE AMERICAN PIKA: DIVERSITY AND BIOGEOGRAPHY IN NORTH AMERICA’S INTERMOUNTAIN WEST
… more similar to that of the host or that of the endoparasites. I characterized the flea diversity and distribution within American pikas based on a sample of 837 flea specimens collected from 34 localities in the Intermountain West. I identified 11 flea species, two of which are common and known …

Population ecology and parasitism in bumble bees (Hymenoptera: apidae)
… sites in Southwestern Virginia were studied. Endoparasites of spring queens included Locustacarus buchneri (Stammer) (Acarina: Podapolipidae), a mite infesting the abdominal air sacs; the nematode Sphaerularia bombi Dufour (Tylenchida: Nematoda), and gregarious braconid larvae, probably …

Non-invasive assessment of stress hormones, parasites, and diet, using scat of five felid species in Belize, Central America
… on adrenal activity, prey consumption, and endoparasites in felids of Belize. These findings could be used for comparisons to populations thought to be affected by human activities across Belize and in neighboring countries.

Identificação de parasitos gastrointestinais em aves silvestres apreendidas em fiscalizações preventivas integradas, Bahia, Brasil
… parasites. This study aimed to identify the main endoparasites found in wild birds seized during Integrated Preventive Inspections (Fiscalizações Preventivas Integradas - FPI) in the state of Bahia, with a focus on evaluating their zoonotic potential and the possible introduction of pathogenic …

Digenetic trematodes and cestodes from fishes of the San Joaquin delta
… is to gain some knowledge of the species of endoparasites of fishes of the San Joaquin Delta. Two hundred and thirty sic fish were examined, including diadromous, potamodramous, anandromous, and territorial species of San Joaquin Delta. This has resulted in the recovery of two previously …

The Influence of Environmental Conditions and Co-Occurring Parasites on Blood Physiology in Eastern Hellbenders (<i>Cryptobranchus alleganiensis</i>)
… appalachiensis</i>) that transmit hematophagous endoparasites (Trypanosoma sp.), often resulting in coinfection. Results indicate that hematocrit and hemoglobin increase in response to acute stress and with temperature. Additionally, the magnitude of the stress-induced hemoconcentration response …

Survey of Nasal Mites (Acari: Rhinonyssidae, Ereynetidae, Turbinoptidae) in Birds from Three States in the United States
<p>Avian nasal mites are obligate endoparasites that spend their entire life in the respiratory system of birds. In North America, bird nasal mites are represented by different unrelated families in three different orders of mites: Rhinonyssidae (Mesostigmata), Ereynetidae (Prostigmata), and the …

Molecular characterization of rodent- and-shrew-borne viruses and the prevalence and intensity of infestation of small mammal fleas, in Namibia
… of both ectoparasites (e.g. fleas and ticks) and endoparasites (e.g. bacteria and viruses). Some parasites are vectors of diseases that infect both humans and wildlife. The main objective of the study was to discover and molecularly characterize novel Hantaviruses and Arenaviruses and to determine …

Developing a genetic toolkit for plant-parasitic nematodes
… two major groups of plant-parasitic nematodes: endoparasites and ectoparasites. The endo-parasites are the most economically important, and consequently the most widely studied. Endo parasitic nematodes, e.g., cyst nematodes, spend most or in some cases their entire life within the host, and …

Exocrine glands in Erotylidae (Coleoptera, Cucujoidea): chemical ecology, morphology and evolution
… Members of this group of Hymenoptera are endoparasites in larvae of numerous families of the Coleoptera, Diptera and Lepidoptera. B. parvulus was hitherto known from species of Nitidulidae, Melandryidae, Phalacridae as well as the erotylid genus Triplax.

EPIDEMIOLOGY AND DISTRIBUTION OF PARASITES OF ANIMAL - SPECIFIC AND ZOONOTIC IMPORTANCE IN PIG FARMS IN NORTHERN ITALY.
… the third research line aimed to identify major endoparasites in wild boars and determine their potential epidemiological link to domestic pig populations. A total of 172 out of 191 animals (90.1%) tested positive for at least one parasitic taxon and statistical analysis revealed a significant …

Individual, Social, and Environmental Factors Associated with Patterns of Parasitic Infection in Capuchin Monkeys (Cebus imitator)
… I first used microscopy to screen samples for endoparasites before collecting individual larvae from those samples for molecular identification using Sanger Sequencing of the ITS-2 genetic marker. I then explored how parasitic infections related to host age, sex, rank, social group, and season. …
