Abstract The genus Amblyomma has the largest number of tick species in the Neotropical region. Amblyomma ovale displays high ecological plasticity and can be found in different habitats and a variety of vertebrate hosts....

Abstract This research aimed to identify the species that make up the helminth fauna of Batrachoides surinamensis, a commercially important fish on Marajó Island and the Bragança region, Pará, Brazil. A total of 146 s...

Abstract Parasite-host interactions are shaped by environmental and biological factors, leading to diverse host impacts ranging from tissue damage to physiological impairments. The Tocantins-Araguaia basin, particularly ...

Abstract The Serra da Canastra National Park is a Conservation Unit where domestic dogs live near populations of maned wolves (Chrysocyon brachyurus). Recognizing the importance of parasitic diseases in endangered specie...

Abstract Leishmaniasis is a parasitic disease caused by Leishmania spp., transmitted to hosts through the bite of female phlebotomine sandflies, with domestic dogs serving as reservoirs for the disease. Understanding the...

Abstract The objective of this study was to describe the positivity of intestinal parasitosis in cats from the city of Jataí, Goiás, as well as to determine the accuracy of different parasitological techniques applied....

Abstract Aplectana comprises species of gastrointestinal helminths commonly found parasitizing amphibians and reptiles worldwide. However, most species of the genus are described based only on morphological traits. Durin...

Abstract Species of the chewing louse genus Neopsittaconirmus Conci, 1942 are host-specific parasites on Old World and Australasian parrots (Psittaciformes), infesting both wild and captive birds. Despite veterinarian pr...

Abstract Rhipicephalus microplus is an ectoparasite responsible for causing economic losses in livestock farming totalling approximately $3.24 billion dollars per year. The main control method involves the use of chemica...

Abstract Growing antiparasitic resistance challenges parasite control in livestock, increasing interest in natural product-based alternatives for animal health and food quality. This study evaluated the in vitro activity...

Abstract The study of the diversity of tick-borne agents in wild animals enables a better understanding of the distribution of pathogens in the country, the identification of potential reservoirs for these agents, the ma...

Abstract Lice are obligatory ectoparasites of birds and mammals, possessing mouthparts adapted for feeding on the blood and/or keratinized tissue of their hosts. Recording parasites that may cause economic and sanitary l...

Abstract This study reports the first record of candiru, Vandellia sp. parasitizing the freshwater stingray Potamotrygon scobina in the Amazon basin, Brazil. In April 2018, a specimen of Potamotrygon scobina was collecte...

Abstract Non-human primates are potential hosts for helminths of various phyla, and the presence of these parasites can cause changes in organ morphology and functionality. In this study, we present the alterations induc...

Abstract We analyzed the distribution of endoparasites in five species of Hylidae frogs during their reproductive period, aiming to understand how the host's habitat influences the parasites. Five anuran species (Boana r...

Abstract This study investigated infection by Leishmania spp., Leptospira spp., Toxoplasma gondii, and Trypanosoma cruzi in six-banded armadillos (Euphractus sexcinctus) from the semiarid region of northeastern Brazil. T...

Abstract The aim of this study was to report infection by Toxoplasma gondii in free-ranging mammals from Pantanal, as well as to compare the laboratory methods used to detect this parasite among native wildlife species. ...

Abstract Representatives of the families Didelphidae, Echimyidae, Cricetidae, and Muridae have been identified as significant reservoirs or amplifiers of zoonotic agents. This study aimed to investigate the molecular occ...

Abstract Haemosporidians belonging to the subgenus Haemoproteus (Parahaemoproteus) and the genus Leucocytozoon rely on dipteran vectors for transmission, with biting midges (Culicoides spp.) and black flies (Simuliidae),...
