Gastrointestinal Helminths of Suliformes Birds from the Southern Coast of São Paulo, Brazil Beatriz Brener, Guilherme Sena, Magda Antonello, Júlia Piolla, Michelle Fonseca, et al. Parasitologia, 2025 Seabirds of the families Fregatidae, Phalacrocoracidae and Sulidae, common on the southeastern coast of Brazil, form colonies and play a bioindicator role in coastal ecosystems due to their ecological habits. This study aimed to identify the prevalence of parasitic helminths in Suliformes birds, of the species Fregata magnificens Mathews, 1914, Sula leucogaster Boddaert, 1783 and Nannopterum um Gmelin, 1789, from the Instituto de Pesquisas Cananeia (IPeC) on the southern coast of the State of São Paulo, and to record the diversity and parasitic indices, since reports of helminth prevalence in pelagic birds are scarce in Brazil. From 2018 to 2020, a total of 270 nematode specimens and 271 acanthocephalan parasites were collected from 51 Suliformes birds (20 F. magnificens, 10 N. brasilianum and 21 S. leucogaster). The host species F. magnificens was parasitized by Contracaecum plagiaticium and Contracaecum pelagicum. The host S. leucogaster was parasitized by C. plagiaticium. In the host N. brasilianum, specimens of Contracaecum australe, Contracaecum rudolphii, Contracaecum multipapillatum, Syncuaria squamata and Andracantha tandemtesticulata were found. This is the first report of C. plagiaticium and C. pelagicum in F. magnificens in Brazilian territory, and of A. tandemtesticulata in N. brasilianum in the southeast region of Brazil.
Intestinal Parasites in Pecari tajacu and Sus scrofa domesticus in the Caatinga from Southeastern Piauí, Brazil Marrara Sampaio, Luciana Sianto, Marcia Chame, Bruna Saldanha, Beatriz Brener Journal of Parasitology, 2023 This study identifies gastrointestinal parasites in the feces of Pecari tajacu (caititu) and Sus scrofa domesticus (domestic pig) in southeastern Piauí, Brazil. The region covers 2 protected areas, Serra da Capivara National Park and Serra das Confusões National Park, and surrounding communities. Fecal samples from 64 animals, 42 from domestic swine and 22 from caititu, collected between 1985 and 2013, were analyzed by optical microscopy. Helminths and/or protozoa were found in 64% of the domestic pig samples and 27% of the caititu samples, totaling 18 morphospecies: Nematoda, Spirurida (2 morphospecies), Trichostrongyloidea, Eimeriidae, Aspidodera sp., Bertiella sp., Metastrongylus sp., Trichostrongylus sp., Moniezia sp., Gongylonema sp., Trichuris suis, Spirocerca lupi, Macracanthorhyncus hirudinaceus, Globocephalus urosubulatus, Strongyloides cf ransomi, Balantioides coli, and Eimeria cf scabra. The highest parasite diversity was obtained in the pig samples, totaling 15 morphospecies, compared to only 6 in caititus, with S. cf ransomi, G. urosubulatus, and S. lupi present in both hosts. We discuss the presence of parasites associated with domestic animals around the Protected Areas and potentially zoonotic parasites close to human communities, which raise concerns about the conservation of wildlife, human health, and livestock in the region.
Cryptosporidiosis in Reptiles from Brazil: An Update for Veterinary Medicine Beatriz Brener, Eduardo Burgarelli, Marianne Suarez, Lucas Keidel Parasitologia, 2022 The concern about the protection of wildlife has been gathering attention from researchers worldwide. Zoos and aquariums have become widely recognized sites for the conservation of wildlife. However, the persistence of the illegal trade of wild animals, such as reptiles, and their use as pets can endanger not only the preservation of the species, but also allow the introduction of new pathogens and zoonotic diseases. It is important to highlight that preventive exams should be carried out prior to introducing these animals into a new facility to guarantee zoological management strategies. There are several reports of parasitism in reptiles, some of them with zoonotic potential, such as the genus Cryptosporidium spp. In Brazil, reports that explore the prevalence of cryptosporidiosis in reptiles are scarce, and very few have used molecular methods for the detection of Cryptosporidium spp., or the genotyping of its species and subtypes. This review aims to help professionals in the area and encourage them to increase their attention to this protozoan, which is usually neglected.
The Chewing Lice of Brown Booby (Sula leucogaster) in Southeastern Brazil Magda Antonello, Sarah Lira, Eduardo Burgarelli, Mariana de Almeida Novaes Fernandes, Jeferson Rocha Pires, et al. Journal of Parasitology, 2022 The brown booby (Sula leucogaster Boddaert, 1783) has a wide geographic distribution, being found throughout the intertropical range except for the west coast of South America. Chewing lice (Phthiraptera: Amblycera and Ischnocera) are ectoparasites commonly found in association with a wide variety of bird species, and extensive infestations can lead to severe itching and irritation that causes skin lesions, damage to the plumage, and abandonment of nests. Sula leucogaster lice have an atypical distribution, not fully following the distribution of their host. In the years 2018 and 2019, 4 marine animal rehabilitation centers located in Rio de Janeiro and São Paulo, Brazil received live birds and carcasses of Sula leucogaster. The animals were deloused and lice of 2 different species were collected. Identification was performed by optical microscopy, and the species found were Eidmanniella albescens Piaget, 1880 and Pectinopygus garbeiPessoa and Guimarães, 1935. This is the first record of both species in Rio de Janeiro.
Chewing Lice of Fregata magnificens with First Record of Fregatiella aurifasciata (Phthiraptera: Amblycera) in Brazil Magda Antonello, Rubem F. S. Menna-Barreto, Daniela Leles, J. R. Pires, Beatriz Brener Journal of Parasitology, 2020 The genus Fregata includes 5 species, with 3 recorded in Brazil, with Fregata magnificens being the most abundant. However, its ectoparasitic fauna is still little known. This study aimed to evaluate the incidence of ectoparasites of F. magnificens residing along the coast of Rio de Janeiro and São Paulo collected by 2 animal rehabilitation centers. Samples were collected from 5 frigatebirds of the Instituto Argonauta in São Paulo and 10 frigatebirds of the Centro de Recuperação de Animais Selvagens (CRAS) in Rio de Janeiro. Species of lice were identified using both morphological and molecular methods. Scanning electron microscopy was also used for identification. Colpocephalum spineum, Fregatiella aurifasciata, and Pectinopygus fregatiphagus were identified. All 3 louse species have previously been recorded from this host outside Brazil, but only P. fregatiphagus has been recorded from Brazil. This paper reports the first occurrence of F. aurifasciata and C. spineum in Brazil. It is also the first record of P. fregatiphagus in the state of Rio de Janeiro.
Parasitism in snakes Beatriz Brener, Annelise Amorim Rique, Amanda Leichsenring Diniz, Patricia Riddell Millar Medicina Veterinaria Brazil, 2020 A criação cativa de serpentes tem sido cada vez mais intensificada devido ao seu uso como pet, conservação de animais selvagens, importância em pesquisas, desenvolvimento tecnológico, produção de soro antipeçonha e outros produtos. O parasitismo nestes animais é frequente, podendo atingir alta carga parasitária, a qual pode ser intensificada com o estresse de cativeiro que leva à depressão do sistema imunológico. Os parasitos não apenas influenciam na viabilidade dos animais mantidos em cativeiro, como também podem ter potencial zoonótico. Esta revisão visa auxiliar profissionais da área na manutenção adequada de serpentes em cativeiro.
Are immunoenzymatic tests for intestinal protozoans reliable when used on archaeological material? Daniela Leles, Liesbeth Frías, Adauto Araújo, Beatriz Brener, Adriana Sudré, et al. Experimental Parasitology, 2019 Intestinal protozoans found in ancient human samples have been studied primarily by microscopy and immunodiagnostic assays. However, such methods are not suitable for the detection of zoonotic genotypes. The objectives of the present study were to utilize immunoenzimatic assays for coproantigen detection of Cryptosporidium sp., Giardia duodenalis, and Entamoeba histolytica/Entamoeba dispar in sixty ancient human and animal samples collected from 14 archaeological sites in South America, and to carry out a critical analysis of G. duodenalis according to results obtained from three diagnostic methodologies: microscopy, immunodiagnostic tests (immunoenzymatic and immunofluorescence), and molecular biology (PCR and sequencing). More than half (31/60) of the samples analyzed using immunoenzymatic tests were positive for at least one of the intestinal protozoans, with 46.6% (28/60) corresponding to G. duodenalis, 26.6% (16/60) to Cryptosporidium sp., and 5% (3/60) to E. histolytica/E. dispar. Cryptosporidium sp. and G. duodenalis coinfection was observed in 15% (9/60) of the samples, whereas all three protozoans were found in 5% (3/60) of samples. In the Northeast Region of Brazil, by immunoenzymatic tests there is evidence that G. duodenlais and Cryptosporidium sp. have infected humans and rodents for at least 7150 years. However, for G. duodenalis, the results from the three diagnostic tests were discordant. Specifically, despite the efficiency of the molecular biology assay in the experimental models, G. duodenalis DNA could not be amplified from the ancient samples. These results raise the following question: Are all ancient samples positive for coproantigen of G. duodenalis by immunoenzymatic tests truly positive? This scenario highlights the importance of further studies to evaluate the sensitivity and specificity of the immunoenzymatic method in the archaeological context.
Integrative taxonomy reveals a new species of Dollfusentis (Acanthocephala: Illiosentidae), in Orthopristis ruber (Osteichthyes: Haemulidae) from Rio de Janeiro, Brazil Lucas Keidel, Martín García-Varela, Beatriz Brener, Gerardo Pérez-Ponce de León, Cláudia Portes Santos Parasitology International, 2019 The taxonomy of species of Dollfusentis is rather confused due to the overlap of morphological traits. The aim of this study was to follow an integrative taxonomy approach over the acanthocephalans collected from Orthopristis ruber in Brazil. Dollfusentis lenti n. sp. is described and is characterised by having an elongate trunk with spines sparsely distributed (largest 60-85 μm long) extending from the neck to almost reach the end of proboscis receptacle; additionally, the new species possesses a long proboscis with 12-14 longitudinal rows of 16-17 hooks each; 3-4 posterior hooks reduced in size, well-spaced from the eight ventrolateral crescent hooks, and lemnisci longer than proboscis receptacle. New sequences of 18S rDNA, ITS1, 5.8S and ITS2, 28S rDNA and COI mtDNA are provided. Dollfusentis bravoae is morphologically similar because it possesses the same number of proboscis hooks, although it differs by the size of testes and uterus and by having a higher number of trunk spines; additionally, new scanning electron micrographs and genetic data for both species support its distinction. Phylogenetic analysis obtained either with two nuclear genes or mitochondrial COI gene showed that Dollfusentis spp. belong to Illiosentidae, and the new species is yielded as the sister species of D. bravoae, with D. chandleri as the sister species of the latter two.
