A case of human intraocular dirofilariasis is reported from northern Brazil. The nematode was morphologically and phylogenetically related to Dirofilaria immitis but distinct reference sequences, including those D. infesting dogs in the same area. zoonotic species wild mammals Brazil its implications are discussed.
Morphological descriptions of Dirofilaria immitis are scarce. For this reason, we carried out morphological studies using both light and scanning electron microscopy for filaroid species. Morphometric data were compatible with previous D. immitis, but several anatomical structures described by the first time, such as details cuticular striations, positioning amphids, visualization anal vulvar opening, deirids, lateral line, pair phasmids in posterior end females, a small latero-terminal...
Absctract Eustrongylides spp. nematodes have birds as final hosts and uses other vertebrates intermediate/paratenic host (fish, amphibians reptiles) zoonotic potential. In amphibians, the larvae may be located in subcutaneous tissues, liver mesentery, between muscle fibres, especially lower limbs. Rhinella marina, which is widely observed Brazil, has exhibited complex diversity its helminth fauna, reflecting unique habitat of Amazon biome. For first time, this study describes morphological...
The nematode parasites of Rhinella marina include species the genus Rhabdias (Rhabdiasidae: Rhabditoidea). present study describes paraensis sp. nov., which parasitizes lungs R. in Brazilian Amazonia. Of more than 70 known this genus, 18 are bufonids, which, eight Neotropical. new described here is similar to alabialis absence lips different by presence conspicuous cephalic papillae. We describe details four rows pores, distributed equally along whole length body and connected with...
In Brazil there are several records of parasitic nematodes fish with zoonotic potential, especially those belonging to the family Anisakidae. This study considers morphology, morphometry and prevalence Contracaecum in Astronotus ocellatus , consumed Amazon sold as ornamental it also performs a retrospective analysis diversity larvae Contracaecum, studies carried out over period 90 years. 40 specimens A. were necropsied, collected fixed 93 parts 70% ethyl alcohol, 5 formaldehyde, 2 glacial...
Dirofilaria immitis and Acanthocheilonema reconditum are common parasites in dogs but have also been reported parasitizing humans. The differential diagnosis epidemiological evaluation of these zoonoses important to the development efficient public health policies control strategies. purpose this study was carry out an survey by using molecular methods for specific identification filarid domestic Marajó mesoregion, State Pará (PA), Brazil. A total 418 canine blood samples from mesoregion...
Calodium hepaticum (syn. Capillaria hepatica) is a trichurid nematode that parasitizes the hepatic parenchyma of rodents and other mammals. Infections in humans are rare, although they have been reported worldwide. A number factors contribute to distribution this zoonosis, particularly presence dense populations associated with relatively poor urban environments, such as those found parts northern Brazilian city Belém eastern Amazon Basin. This study quantifiedCalodium infections commensal...
Exposure to parasites is considered be an important factor in the development of many diseases and histopathologies which are result parasite–host interaction. The present study evaluated impact natural infection by larvae Ortleppascaris sp. (Nematoda: Ascaridida) liver cane toad Rhinella marina (Linnaeus, 1758). Larvae were encysted nodules delimited collagenous fibers fibroblasts or freely within hepatic parenchyma, provoking a clear response from host. histological examination revealed...
The family Nematotaeniidae, tapeworms commonly found in the small intestines of amphibians and reptiles, includes 27 recognised species distributed among four genera: Bitegmen Jones, Cylindrotaenia Jewell, Distoichometra Dickey Nematotaenia Lühe. taxonomy these cestodes is poorly defined, due part to difficulties observing many anatomical traits. This study presents describes a new genus nematotaeniid parasite cane toads (Rhinella marina) from eastern Brazilian Amazonia. were collected...
N Bertiella is a genus of the Anoplocephalidae family that includes parasites mammals can infect humans.N The specific identification based on morphological features and geographical localization infection.N Molecular approaches with phylogenetic relationships genetic sequences are tools be used in similar cases.
Mesocoelium lanfrediae sp. nov. (Digenea: Mesocoeliidae) inhabits the small intestine of Rhinella marina (Amphibia: Bufonidae) and is described here, with illustrations provided by light, scanning electron microscopy molecular approachs. M. presents typical characteristics genus, but morphometrically morphologically different from species previously. The main diagnostic are (i) seven pairs regularly-distributed spherical papillae on oral sucker, (ii) ventral sucker outlined four distributed...
Abstract Aspidogastreans are commonly found infecting freshwater and marine molluscs, teleosts fishes turtles. The subclass comprises four families – Rugogastridae Schell 1973, Stichocotylidae Faust & Tang 1936, Multicalycidae Gibson Chinabut 1984 Aspidogastridae Poche 1907 it is characterized by the presence of a ventral adhesive disc divided into rows alveoli. In current work, using light scanning electron microscopy molecular approaches, new species genus Rohdella Chinabut, 1984,...
Abstract A new species of Myxobolus parasitizing the arterial bulb and cardiac musculature freshwater fish Pimelodus ornatus Kner, 1858, from Arari river in municipality Cachoeira do Arari, island Marajó, Pará, Brazil, was described. In present study, observed prevalence myxozoan parasites heart tissue hosts 20% (6/30). The myxozoans had mature biconvex spores, slightly rounded, an anterior end with two pyriform polar capsules a posterior very evident sporoplasm, measuring 8 ± 0.2 μmin...
Cucullanus ageneiosus n. sp. (Nematoda: Cucullanidae) is described from the intestine of Ageneiosus ucayalensis, Guajará Bay, Belém, Pará, Brazil. The new species characterized mainly by arrangement male caudal papillae, and position lateral phasmids immediately posterior 10th markedly short unequal spicules, a precloacal sucker, presence an unpaired median papilla just anterior cloacal lip.
This study presents a new record for the occurrence of larval Ortleppascaris sp.(Sprent, 1978). The nematodes were collected from inside fibrous cysts found in livers cane toads, Rhinella marina (Linnaeus, 1758), captured eastern Brazilian Amazonia. is first sp. larvae both Brazil and this amphibian host, increasing its distribution South America as well expanding number helminths known to infect toad. detailed description provides taxonomic data these larvae, sequences internal transcribed...
Dipetalonema gracile (Rudolphi, 1809) (Filarioidea: Onchocercidae) is one of six species cavities filarial parasites Neotropical non-human primates. The present study recorded the occurrence D. gracile, provides morphological and morphometric data extends geographical distribution. Adult filariae were obtained from thoracic abdominal 38 specimens woolly monkey, which used for local human consumption, in northeastern Peruvian Amazon.

Abstract Dipetalonema caudispina (Molin, 1858) and D. gracile (Rudolphi, 1809) (Filarioidea: Onchocercidae) are two of six known species filarial nematodes that parasitize Neotropical non-human primates. Adult filariae were collected from the thoracic abdominal cavities 38 44 specimens Sapajus macrocephalus (Spix, 1823) nine ten Cebus albifrons (Humboldt, 1812) (Primates: Cebidae), distributed in Yavarí-Mirín river basin used locally for human consumption. Co-occurrence is reported first...
Ortleppascaris sp. is a helminth that, in its larval stage, infects the liver parenchyma of amphibian Rhinella marina, resulting severe physiological and pathological changes. This study used proteomic approach to determine overall profile proteins expressed somatic extract from nematodes investigate relationship between parasite host.
