RABBITS AS PARATENIC HOSTS OF TOXOCARA CANIS

THEORY AND PRACTICE OF PARASITIC DISEASE CONTROL, 2023
Toxocariasis is both a veterinary and medical problem worldwide. A feature of Toxocara biology is that Toxocara larvae commit visceral larva migrans, damage the liver, lungs, and other organs and tissues in non-specific hosts, including humans. Constant reinvasion leads to the accumulation of stage 2–3 larvae in the body of ...

Two Strategies of Acanthocephalan Interrelations with Paratenic Hosts

Biology Bulletin, 2019
Data available on the peculiarities of the tegument structure and encapsulation of the acanthocephalans Corynosoma strumosum (Palaeacanthocephala, Polymorphidae) and Sphaerirostris picae (Palaeacanthocephala, Centrorhynchidae) in paratenic hosts are summarized.

Distribution of Toxocara infection in the environment and in definitive and paratenic hosts in Estonia

Acta Veterinaria Hungarica, 2006
The aim of the study was to elucidate the distribution and possible transmission routes of Toxocara spp. infection in Estonia. Out of 454 faecal and sand samples collected from park lawns and sandpits in the town of Tartu, 19 were Toxocara positive (4.2%). Out of the 45 sandpit samples 17.8% were Toxocara positive.

Nucella lapillus as a paratenic host for Maritrema arenaria

Journal of Helminthology, 1999
Metacercariae of the microphallid trematode Maritrema arenaria are found in the shore barnacle Semibalanoides balanoides which is heavily predated by the dog whelk, Nucella lapillus. This study demonstrated that, under experimental and natural conditions, M. arenaria metacercarial cysts were ingested by N.

Prey species of franciscana Pontoporia blainvillei as paratenic hosts of helminths

Diseases of Aquatic Organisms, 2017
The distribution of franciscana Pontoporia blainvillei Gervais & d'Orbigny, 1884, is restricted to the estuarine and coastal waters of the southwestern Atlantic. The diet of this dolphin is composed of fishes, squids, and shrimps, many of which harbor helminths that may infect franciscana.

Histopathology of Nymphal Pentastomid Infections (Sebekia mississippiensis) in Paratenic Hosts

The Journal of Parasitology, 1991
The histopathologic alterations occurring in mice, hamsters, turtles, and a frog were described following experimental infection with nymphs of Sebekia mississippiensis. Initially, nymphal migration caused traumatic tissue damage and hemorrhage characteristic of larva migrans.

Hairworm Infection and Seasonal Changes in Paratenic Hosts in a Mountain Stream in Japan

Journal of Parasitology, 2017
For parasites with complex life cycles, the ecological traits determining host competence and seasonal changes in infection in natural habitats are often unclear, making it difficult to predict infection dynamics, including disease outbreaks. Hairworms (phylum Nematomorpha) require both aquatic and terrestrial hosts to complete their life cycle ...
