The Dangerous Side of Being a Predator: and in Birds of Prey.

and are apicomplexan protozoa of major concern in livestock and is also considered one of the major threats and a public health concern. These protozoa have a wide range of intermediate hosts, including birds. The present work aimed to assess the prevalence of these cyst-forming parasites in migratory and sedentary birds of prey.

Anthelmintic Efficacy in Sheep and Goats under Different Management and Deworming Systems in the Region of Lisbon and Tagus Valley, Portugal.

Infections caused by gastrointestinal parasites have been described worldwide as one of the most important issues impacting small ruminant production. The systematic administration of anthelmintic (AH) drugs without following good practice principles has led to an increase in anthelmintic resistance (AR). There is scarce information regarding AH efficacy in small ruminants in Portugal.

Global prevalence of Trichinella in pigs: A systematic review and meta-analysis.

Background: Investigating the global epidemiological patterns of Trichinella in pigs is required for accurate recognition and to establishing proper control programmes and preventive measures, as well as to decrease human exposure.

Objectives: To obtain a better understanding of the global prevalence of Trichinella in domestic pigs and factors that might influence the prevalence, a systematic review and meta-analysis was performed.

Methods: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed.

The global prevalence of Spirometra parasites in snakes, frogs, dogs, and cats: A systematic review and meta-analysis.

Background: Spirometra infection is aneglected food- and waterborne disease with worldwide distribution.

Objectives: The present study aims to estimate the global prevalence of Spirometra species in snakes, frogs, dogs and cats.

Methods: Multiple databases (PubMed, Scopus, ProQuest, Web of Science and Google Scholar) were searched for relevant literatures published up to March 2022.

Zoonoses as Important Causes of Hospital Admissions: A 15-Year Study in Portugal.

Introduction: Zoonoses represent 75% of emerging diseases. These diseases pose a permanent threat to human health and well-being and have the potential to become increasingly frequent due to habitat degradation; land-use changes; and increased global mobility of humans, animals, and animal products. The objective of this study was to investigate the impact ten zoonoses (brucellosis, cysticercosis, echinococcosis, leishmaniasis, leptospirosis, Lyme disease, rabies, toxoplasmosis, trichinellosis, and West Nile fever) had on human hospitalizations between 2002 and 2016 in Portuguese National Health Service hospitals.

Gastrointestinal Parasitism in Miranda Donkeys: Epidemiology and Selective Control of Strongyles Infection in the Northeast of Portugal.

In Portugal, equine parasitism in pasture animals is characterized by high parasitic burden and high helminthic biodiversity; both factors are potentially pathogenic for their hosts. The decrease in the number of donkeys over the last years in Portugal, their importance in rural lowland and mountain ecosystems and pastures and the scarce information regarding their parasitism led to this research, which aimed to evaluate the parasitological status of a Miranda donkey breed population, a native breed mainly located in the northeast of Portugal. This study provides better knowledge of their gastrointestinal parasitism, particularly strongyles, and the assessment of a targeted selective treatment (TST) as an alternative control approach of their parasitism.

Identification of third stage larval types of cyathostomins of equids: An improved perspective.

Cyathostomins comprise around 50 parasite species of equids, offering a great challenge regarding their individual identification. The objective of our work was to improve identification of infective third stage larvae (L3) with a morphological key supplemented with detailed scientific illustrations based on our research and available literature. The highlighted features were; the number, arrangement, and shape of intestinal cells (IC), general features and the total body length of the eight different Cyathostomin sensu latum types (Type A, B, C, D, E, F, G, H), Gyalocephalus capitatus, and Posteriostomum spp.

Feeding horses with industrially manufactured pellets with fungal spores to promote nematode integrated control.

The usefulness of pellets industrially manufactured with spores of parasiticide fungi as a contribution to integrated nematode control was assessed in grazing horses throughout sixteen months. Two groups of 7 Pura Raza Galega autochthonous horses (G-T and G-P) were dewormed pour-on (1mg Ivermectin/kg bw) at the beginning of the trial, and other group (G-C) remained untreated. The G-P was provided daily with commercial pellets to which was added a mixture of fungal spores during the industrial manufacturing (2×10 spores of Mucor circinelloides and same dose of Duddingtonia flagrans/kg), and G-T and G-C received pellets without spores.

Taeniid species of the Iberian wolf (Canis lupus signatus) in Portugal with special focus on Echinococcus spp.

Taeniid species represent relevant pathogens in human and animals, circulating between carnivorous definitive hosts and a variety of mammalian intermediate hosts. In Portugal, however, little is known about their occurrence and life cycles, especially in wild hosts. An epidemiological survey was conducted to clarify the role of the Iberian wolf as a definitive host for taeniid species, including Echinococcus spp.
