The study identified Contracaecum pelagicum (Johnston & Mawson 1942) as a parasite found in Sphenicus magellanicus (Forster, 1837), and a low sampling of infected hosts was observed, with a prevalence of 33.3%, average intensity of 6/host, and mean abundance of 2±3.46. This occurrence is uncommon in the Northeast region of Brazil, where previous records indicate a higher presence in the southern region of the country. This contributes to the understanding of the geographic distribution of the parasite. Anisakids, such as C. pelagicum, have a complex life cycle involving aquatic invertebrates, fishes, and seabirds. The presence of this parasite may indicate ecological interactions in the marine ecosystem of the region. It is important to report the discovery to relevant authorities and institutions to monitor and control the presence of the parasite. These findings are relevant to th...

Isopods are ectoparasitic crustaceans of marine and freshwater fish with diverse morphology where taxonomic studies involve a series of methods for collection, fixation and techniques for illustrating the species. These methods are applied in a series of studies involving ecology, distribution, biodiversity and morphology. However, approaches from the perspective of scientific illustration are often lacking in the study of parasitic isopods. This study provides a background on the illustration of these organisms by observing published works and presents the application of mixed color technique in the illustration of these invertebrates. This study combined information from the literature and ichthyoparasitological studies involving taxonomy and scientific illustration. The history of isopod illustrations revealed that some older illustrations present greater visual and scientific elabora...

Illegal wildlife trafficking is a practice that represents a significant threat to biodiversity and public health in many regions of the world. Birds that are victims of trafficking are subjected to conditions of stress and confinement that favor the proliferation of parasites, compromising animal health and well-being. Furthermore, some of these parasites have zoonotic potential, posing an additional risk to human health. Therefore, this study aims to identify the gastrointestinal parasites present in wild birds originating from trafficking in the São Francisco River Basin region, providing important information about the risks to bird health and human health. Fecal samples were collected from wild birds (n=80) belonging to the orders Passeriformes, Columbiformes, and Psitaciformes. The samples were analyzed using two parasitological techniques: Mini – FLOTAC© and centrifugal-sedime...
