Helminth parasites of the invasive European brown hare (Lepus europaeus) in Brazil: the first report of Bunostomum trigonocephalum in a hare.

Invasive alien species have the potential to introduce pathogens of economic and health importance in new environments. In Brazil, parasites from the non-native European brown hare can be a threat to humans, domestic animals, and wildlife. Therefore, we aimed to describe the helminth fauna of the invasive European brown hare in three Brazilian states (São Paulo, Paraná, and Rio Grande do Sul).

Two case reports of the parasitism of Ophionyssus natricis (Gervais, 1844) (Mesostigmata: Macronyssidae) in captive Epicrates crassus (Cope) (Squamata: Boidae) in Brazil.

There are more than 200 species of Macronyssidae parasitizing reptiles, birds, and mammals worldwide. While most species are found on wild animals, show some degree of geographic, and host group specificity, Ophionyssus natricis thrives on captive snakes and lizards and as a result of the pet trade, has a cosmopolitan distribution. In this study, we are providing new host records for this species for the state of São Paulo, as well as SEM images and the first partial sequences of Brazilian specimens.

and in invasive wild boars () and hunting dogs from Brazil.

The wild boar, an impactful invasive species in Brazil, is subject to population control activities, which often include the use of hunting dogs. Hunters commonly consume wild boar meat, which is also used to feed their dogs, posing a risk of infection for humans and both and for dogs. The study aimed to investigate the prevalence of infection in wild boars (n = 127) and hunting dogs (n = 73) from São Paulo, Rio Grande do Sul, and Paraná states.

Toxoplasma gondii infection in European brown hares (Lepus europaeus) in Brazil.

Toxoplasmosis is a worldwide zoonosis that affects warm-blooded animals, including humans. Wild animals can act as intermediate hosts of this pathogen; thus, this study aims to detect Toxoplasma gondii infection in invasive European brown hares in Brazil. For this, 72 wild European brown hares were captured from July 2020 to June 2022 in three Brazilian states: São Paulo, Paraná, and Rio Grande do Sul.

Rabies Virus-Neutralizing Antibodies in Free-Ranging Invasive Wild Boars () from Brazil.

Rabies, one of the most lethal global zoonoses, affects all mammals. It remains circulating worldwide in sylvatic cycles through terrestrial and airborne reservoirs, and in Brazil, bats are currently the main reservoirs and source of transmission. Wild boars, an important invasive alien species in Brazil, are a proven food source for hematophagous bats and may participate in the Brazilian sylvatic cycle of rabies.

Eutrichophilus cordiceps Mjöberg, 1910 (Ischnocera: Trichodectidae) in Spiny Tree Porcupines (Coendou villosus): New locality records and the first molecular evidence of association with Bartonella sp.

The chewing louse genus Eutrichophilus Mjöberg has 19 species only associated with porcupines (Rodentia: Erethizontidae). Of these species, E. cercolabes, E.

Integrative taxonomy of Metastrongylus spp. in wild boars from Brazil.

Background: Wild boars (Sus scrofa) may cause substantial damage to crops and can spread zoonotic parasites to domestic animals, posing a risk to health and animal production. Metastrongylus spp. can negatively affect the wild boar population, increasing piglet mortality.
