Until recently, Amblyomma cajennense (Fabricius, 1787) was considered to represent a single tick species in the New World. Recent studies have split this taxon into six species. While A. complex or (sensu lato) (s.l.) is currently represented by two Brazil, stricto) (s.s.) and sculptum Berlese, 1888, their geographical distribution poorly known. The of Brazil determined morphological examination all lots large collections collecting new material during three field expeditions possible...
Didelphis aurita Wied-Neuwied, 1826 is a marsupial well adapted to anthropogenic activity and commonly found in urban areas of Brazil. Among the gastrointestinal parasites this opossum, protozoa genus Eimeria are frequently detected. This study investigated biodiversity species infecting D. Southeastern Brazil, provides morphological data on newly discovered Eimeria. From January June 2019, 43 were captured, their fecal samples collected evaluated by salt flotation; positive allowed...
The opossum has been recognized as an intermediate host for many parasites including Besnoitia spp., which is a protozoan that infects various mammals, wildlife species. A limited number of reports using serology, histopathology, and molecular assays have documented the presence B. darlingi in opossums. In present study, samples from three species, Virginia (Didelphis virginiana, n = 33) urban/suburban areas Florida, USA admitted to rehabilitation centers, free ranging white-eared...
O controle biológico é um método desenvolvido para diminuir uma população de parasitas pela utilização antagonista natural. A administração fungos nematófagos aos animais domésticos considerada promissora alternativa na profilaxia das helmintíases gastrintestinais parasitárias. Os desenvolvem estruturas em forma armadilhas, responsáveis captura e destruição dos estágios infectantes nematóides. gêneros Arthrobotrys, Duddingtonia Monacrosporium têm demonstrado eficácia experimentos...
Observou-se a ação in vitro dos fungos nematófagos Duddingtonia flagrans, Monacrosporium thaumasium e Verticillium chlamydosporium sobre ovos de Ascaris lumbricoides. Após sete, dez quatorze dias interação, o fungo promissor ser utilizado no controle biológico Asaris lumbricoides foi (26-30%). Os outros não foram satisfatórios.
Abstract The interaction between Duddingtonia flagrans and infective larvae of Haemonchus contortus was studied in vitro under optical scanning electron microscopy. Trap formation by the fungus started 9 hours after inoculation first were found 11 larval on colonies grown surface dialysis membranes. Scanning micrographs taken 12, 24, 36 48 h predation. Details predation structures fungus–larvae are described. A mucilaginous substance occurred at points adherence traps to nematode cuticle....
Oestrus ovis larvae are obligate parasites of vertebrates and cause cavitary myiasis (oestrosis) in sheep goats. It is also reported as a zoonosis causing ophthalmomyiasis nasopharyngeal myiasis. Despite being relatively common Brazil, epidemiological studies on O. scarce. Considering that the infestation influenced by climate biomes studied region, we aimed to investigate seasonal prevalence among slaughtered northern region state Mato Grosso, Brazil. The heads (n=697) at slaughterhouse...
The viability of a formulation the fungus Monacrosporium thaumasium associated with ivermectin was evaluated for biological control bovine gastrointestinal nematode parasites. Four groups five calves each were placed in pastures stocking rate 1.6 animal/hectare. In group 1 (control), did not receive any treatment. 2, animal received 20g pellets M. orally twice week during six-month period that began onset rainy season (October 23, 2000). 3, same as well two strategic treatments (200 mcg/kg)...
Abstract Nematophagous fungi are used in the biological control of parasitic helminths animals and plants. The association ovicidal predator nematophagous may present a complementary increased action on helminths. Joint growth compatibility predation tests were carried out infective larvae nematode parasites bovines with fungus ovicide Pochonia chlamydosporia Arthrobotrys cladodes . antagonism direct confrontation, antibiosis effect volatile metabolites between isolates P. A. indicated...
Experiments to evaluate the potential ability of nematode-trapping fungus Duddingtonia flagrans (Isolate CG768) prey on Ancylostoma spp. dog infective larvae (L3) in pasteurized soil were performed through several laboratory assays. A microcosm approach was used with increasing fungal concentrations an inoculum a chlamydospore water suspension. The highest provide more consistent larval reduction than lowest concentrations, but no difference observed from 10,000 25,000 chlamydospores per...
