The parasitofauna in the giant Amazon basin, pirarucu (Arapaima gigas Schinz, 1822) cultured in fish farms from the state of Amapá, in eastern Amazonia (Brazil) was investigated. Of the 100 examined fish, 90.0% were par...

Differences in the efficacy of diagnostic techniques employed in the parasitological examination of feces are a limiting factor of this laboratory procedure in the field of Veterinary Parasitology. To verify advances in ...

Abstract This study aimed to evaluate the occurrence of endoparasites in fecal samples of capybaras from anthropized areas in seven cities in the state of São Paulo, southeastern Brazil, and natural areas in two locatio...

Abstract Introduction Trichomonas vaginalis is a protozoan parasite that causes trichomoniasis, a frequently diagnosed infection that accounts for more than half of non-viral sexually transmitted diseases. An increased i...

Abstract This study introduces two recently developed bio-inspired metaheuristic algorithms, Artificial Protozoa Optimizer (APO, 2024) and Dung Beetle Optimizer (DBO, 2023), into long short-term memory (LSTM) networks fo...

This study evaluated the occurrence of parasitic infections in the “pacu” fish Piaractus mesopotamicus and the “patinga” hybrid (P. mesopotamicus x Piaractus brachypomus) in the northwest of São Paulo State, Bra...

Abstract In the aquaculture industry, biocides are routinely used to treat parasitosis in fish, and researchers are continually developing sustainable alternatives that can replace these harsh chemicals. In this context,...

Abstract Toxoplasma gondii, Plasmodium spp., and Leishmania spp. collectively infect billions and cause millions of deaths worldwide. In French Guiana, the geographical coexistence of malaria, acute toxoplasmosis, and cu...

Abstract The aim of this study was to determine the prevalence of infection by Sarcocystis neurona in horses and identify potential risk factors. Were analyzed 427 samples from 36 farms in 21 municipalities in the Alagoa...

Abstract The objectives of this work were to investigate the occurrence of parasites in feces of cats, compare different coproparasitological techniques for their diagnosis and determine associations with parasitism. The...

Abstract Background Identification of risk and protective factors for canine visceral leishmaniasis (CVL) is essential to understand the epidemiology of the disease and direct prevention and control strategies. Building ...

Cryptosporidium parvum oocysts were detected in feces of dairy calves raised in Rio de Janeiro State and the risk factors involved in the infection were determined. A hundred calves aging up to 12-month-old from 13 dairy...

The diversity of Sarcocystis spp. infecting Alaskan marine mammals is largely unknown, which is relevant in a region of the world where hunting and consumption of marine mammals is essential to Alaskan native food securi...

Methane (CH4) generated during ruminal fermentation in ruminants is a major contributor to greenhouse gas emissions and represents a substantial loss of dietary energy. Therefore, mitigating enteric CH4 emissions through...

Cystic echinococcosis (CE) is a worldwide parasitic zoonosis caused by the larval stage of Echinococcus granulosus. Current chemotherapy against this disease is based on the administration of benzimidazoles (BZMs). Howev...

Abstract Trypanosoma evansi is an important protozoan pathogen affecting various animal species particularly camels and horses, leading to significant economic losses. The ineffective control of T. evansi is attributed t...

Abstract Leishmaniasis is a vector-borne zoonotic disease caused by protozoa in the genus Leishmania, typical of rural and peri-urban environments. The causative agent of American visceral leishmaniasis is Leishmania (Le...

Since November 2007 until May 2009, 1,778 serum samples of cattle from dairy herds of the Southwest of Paraná State, Brazil, were used for search of anti-Neospora caninum antibodies. The frequency of seropositive animal...
