“…Furthermore, the epithelial of tadpoles compared to adults is more sensitive and wet in these areas, facilitating adhesion of parasites (Salinas et al., 2016). According to some studies, as parasite infestation increases, of host mortality also increases (Martins and Souza, 1996). A long-term monitoring of the parasites and amphibian in this basin is highly recommended (Sayyadzadeh and Roudbar, 2014).…”

The introduction of invasive species is one of the greatest threats currently faced by natural ecosystems, causing ecological imbalances between native populations and transmission of a variety of diseases. We reported the interaction between two exotic species given by the parasitic infestation of the copepod Lernaea cyprinacea in the early stages of the development of the American bullfrog Lithobates catesbeianus in the central area of Argentina. In this paper we analysed the leukocyte profile of parasitized and non-parasitized tadpoles of L. catesbeianus with L. cyprinacea and their body condition (BC) as biomarkers of the health status of organisms. A total of 27 tadpoles of L. catesbeianus were analysed (12 non-parasitized and 15 parasitized). The lower BC recorded in parasitized organisms show a lower health status in these tadpoles, which could be affecting the metamorphosis and therefore impact at the population level. Leukocyte response of L. catesbeianus tadpoles to the parasitism of L. cyprinacea was found. Mature and immature lymphocyte frequencies and hematocrit were higher in parasitized compared to non-parasitized tadpoles, which is a typical response to the presence of parasites. However, eosinophils and monocytes were recorded at high frequencies in not parasitized tadpoles, which could be due to the important role played by these leucocytes in the metamorphosis of frogs. The results of this study constitute a first antecedent on leukocyte profile in aquatic stages of anurans during an ectoparasitosis and its possible implications for environmental health. The parasitism of L. cyprinacea influences the biology of the American bullfrog at both the individual and population levels. Parasitized individuals are not killed directly by the parasite, but they can create conditions for secondary infections, growth retardation, behavioral changes and, ultimately, reduce populations.

Resumo: Hoplias malabaricus Bloch, 1794 é uma das espécies de peixes mais comumente encontrada nos açudes da Microrregião do Cariri Paraibano, todavia ainda não existem estudos na região sobre a sua fauna parasitária. Em virtude disso, o estudo objetivou caracterizar a fauna ectoparasitológica, o perfil hematológico e os achados histopatológicos das brânquias de H. malabaricus provenientes de quatro açudes localizados no município de Sumé/PB. Em cada açude foram capturados 10 exemplares e foi realizada a análise limnológica da água. Realizou-se a biometria dos exemplares e foram colhidas amostras sanguíneas por venopunção caudal. Os métodos de coleta de parasitos foram realizados segundo as recomendações da literatura. Além disso, foram coletadas amostras de brânquias para avaliação histopatológica. A comparação das médias foi feita pelo Teste Tukey a 5% de probabilidade. Os resultados mostram que a ectoparasitofauna de H. malabaricus provenientes de açudes localizados no município de Sumé/PB apresentou-se diversificada, sendo identificados vários táxons de ectoparasitos na superfície corporal e brânquias. A fauna parasitária promoveu alterações hematológicas e histopatológicas nas brânquias. Além disso, os resultados evidenciam uma relação de epibiose de Epistylis sp. com Lernaea cyprinacea e crustáceos branquiúros em H. malabaricus.

“…Infections of parasites other than helminths have not been reported in P. bedriagae. Although infections of Lernaea cyprinacea Linnaeus, 1758 are documented for adult and larval anurans worldwide (Baur 1962, Martins and Souza 1996, Alcalde and Batistoni 2005, Kupferberg et al 2009, Salinas et al 2016, the parasite has not been reported in anurans from Turkey.…”

Prevalence and pathology of Lernaea cyprinacea (Crustacea: Lernaeidae) parasitizing tadpoles of Pelophylax bedriagae (Anura: Ranidae) in Antalya, Turkey. This is a report of the frst record of the occurrence of Lernaea cyprinacea on tadpoles of Pelophylax bedriagae, a frog species native from Karpuzçay Creek, Antalya, Turkey. A total of 20 tadpoles of P. bedriagae were examined and 14 (70%) specimens were infected. A maximum of two parasites per host was found, primarily around the cloaca. In general, slight to moderate hyperemia was noticed around the parasite. Typically, granuloma form in the tissues around the parasite. Histopathological examination revealed that hemorrhages and pathological lesions such as dermal erosions, and a chronic infammatory reaction in skin and muscle were present at the site of parasite attachment.
