The aeglids are freshwater crustaceans, playing an important role in the trophic chain for various invertebrate and vertebrate organisms. A specimen of Aegla spinosa Blond-Buckup & Buckup, 1994, from the interior of the municipality of Bocaina do Sul, state of Santa Catarina, was brought to the Laboratory of Parasitology and Zoology at the University of Planalto Catarinense (UNIPLAC). The examined crustacean presented three specimens of Temnocephala. As these animals are vulnerable to environmental changes and alterations in the natural landscape due to anthropic pressure, knowing the presence of temnocephalids can contribute to understanding the associations between these organisms and their hosts, especially in the state of Santa Catarina, where there is a lack of descriptions for the invertebrate fauna.

A single specimen of Belostoma sp., a hemipteran belostomatid insect from the interior of the city of Bocaina do Sul, state of Santa Catarina, was brought to the Laboratory of Parasitology and Zoology of Universidade do Planalto Catarinense (UNIPLAC), Brazil. The hemipteran examined was infested with two specimens of Temnocephala curvicirri Amato & Amato, 2005, found on the ventral surface of Belostoma sp. between the second and third locomotor pair of the insect. Externally, the light colored helminth is characterized by the presence of an adhesive disk with a fingerlike appearance. The temnocephalid was identified by its extremely long and curved cirrus. This is the first report of the presence of T. curvicirri in Santa Catarina.

This study investigates the parasitic fauna of Mugil curema Valenciennes, 1836 (Mugilidae) from Laguna, southern Santa Catarina, Brazil, being the first parasitological survey of this species in the region. A total of 52 specimens were examined for ecto- and endoparasites. The external examination revealed Ergasilidae specimens and copepod eggs on the gills, while the monogenean Metamicrocotyla macracantha (Alexander, 1954) was identified. Internal prospection showed the presence of the acanthocephalan Neoechinorhynchus curemai Noronha, 1973 and one unidentified digenean from the family Haploporidae. Histopathological analysis revealed hepatic lesions and mild inflammation in intestinal tissue. These findings underscore the importance of parasites in M. curema, contributing to the ecological understanding of parasitism in marine fish and its potential implications for human health and en...

Capillaria plica Rudolphi, 1819, a parasitic nematode, infects the urinary tract of both domestic and wild carnivores.Despite its global presence, clinical reports are rare in certain regions, including Brazil. Th is study documents the first occurrence of C. plica in a Puma concolor Linnaeus, 1771 (Puma) from Santa Catarina, southern Brazil, marking the first report of this parasite in the southern part of the country. Necropsy and urinary sediment analysis revealed the presence of C. plica eggs and adult nematodes. The parasite’s diagnosis is challenging due to its subclinical nature and the difficulty in visualizing eggs and adults, especially in wild felids. This case highlights the importance ofurinalysis in wild carnivores for diagnosing urinary capillariasis and emphasizes the need for heightened awareness of this parasitic disease, particularly in under-researched regions.
