“…Dipetalonema gracile is pathogenic for squirrel monkeys and may be found free in the peritoneal cavity or bound up in the mesentery (Zhang et al, 2020), as observed in the present case. However, to the best of our knowledge, this is the first report of D. gracile parasitism in S. flavius.…”

Parasitic infections are important concern to the Wildlife Conservation Biology, particularly in endangered species. Herein, we report a parasitism by Dipetalonema gracile Rudolphi, 1809 (Spirurida, Filarioidea, Onchocercidae), in the peritoneal cavity of a captive Marcgrave’s capuchin monkey (Sapajus flavius) that died at the Wild Animal Screening Center (CETAS) of the Brazilian Institute for the Environment and Renewable Natural Resources (IBAMA) in the municipality of Cabedelo, state of Paraíba, northeastern Brazil. The necropsy revealed two filarial worms D. gracile in the abdominal cavity. Exudates, thin fibrin layers and fibrous adhesions were also present in the mesentery and spleen capsule. The mesenteric, mandibular, and tracheobronchial lymph nodes were enlarged. Multiple small nodules were seen in the spleen parenchyma. Microscopic examination of the lymph nodes and spleen revealed markedly and diffuse inflammatory reaction, with edema, plasma cells, eosinophils, histiocytes, lymphocytes and rare multinuclear giant cells, with obliteration of the normal histological architecture of the organ. This is the first report of D. gracile parasitism in Marcgrave’s capuchin monkeys, a critically endangered species. Studies of this nature significantly contribute to the knowledge of the parasitic fauna of endangered species, in addition to helping to formulate conservation strategies (in situ and ex situ) and records of new hosts and new areas of occurrence of parasites.

“…Phytochemicals, also referred to as phytobiotics or phytogenics, are natural bioactive products derived from plants. They include mainly essential oils [1], flavonoids [2], terpenes [3], polysaccharides [4], and phenolic acid [5]. Currently, phytochemicals were studied widely because of their multiple functions in human and animal health [6,7].…”

Effect of Manitoba-Grown Red-Osier Dogwood Extracts on Recovering Caco-2 Cells from H2O2-Induced Oxidative Damage

et al. 2019

Red-osier dogwood, a native species of flowering plant in North America, has been reported to have anti-oxidative properties because of abundant phenolic compounds; this could be promising as a functional food or a feed additive. In the present study, an oxidative damage model using 1.0 mM hydrogen peroxide (H2O2) in Caco-2 cells was established to evaluate the antioxidative effects of red-osier dogwood extracts (RDE). The results showed that 1.0 mM H2O2 pre-exposure for 3 h significantly decreased cell viability, and increased interleukin 8 (IL-8) secretion and the intracellular reactive oxygen species (ROS) level. Caco-2 cells were treated with 100 µg/mL RDE for 24 h after pre-exposure to H2O2. It was found that the decreased cell viability caused by H2O2 was significantly restored by a subsequent 100 µg/mL RDE treatment. Furthermore, the IL-8 secretion and ROS level were significantly blocked by RDE, accompanied by the enhanced gene expression of hemeoxygenase-1 (HO-1), superoxide dismutase (SOD), and glutathione peroxidase (GSH-Px), and the enhanced protein expression of the nuclear factor (erythroid-derived 2)-like 2 (Nrf-2). Moreover, RDE improved barrier functions in Caco-2 cells. Using RDE reduced the diffusion of fluorescein isothiocyanate (FITC)-dextran and increased the transepithelial resistance (TEER) value. The relative mRNA level of tight junction claudin-1, claudin-3, and occludin was elevated by RDE. These extracts also repaired the integrity of zonula occludens-1 (ZO-1) damaged by H2O2 and increased the protein expressions of ZO-1 and claudin-3 in the H2O2-pretreated cells. These results illustrated that RDE reduced the ROS level and enhanced the barrier function in oxidative-damaged epithelial cells.

“…Molecular marker with high speci city represents an essential genetic tool, which could be used for rapid species identi cation and as an effective complement to traditional classi cation methods (Hebert et al, 2003;Zhang et al, 2018). The ITS sequence have been proven as speci c genetic markers that can not only be used for the rapid detection of parasites but also have diverse applications in analyzing parasites polymorphism and genetic variation (Zhu et al,1998;Shamsi et al, 2008).…”

Members of genus Ophidascaris are common parasitic roundworms in snakes that cause gastric granulomas, adenocarcinomas, intestinal obstruction, death, and serious economic losses in snakes and their products. To identify molecular marker of Ophidascaris baylisi from the Burmese python (Python molurus bivittatus), we amplified internal transcribed spacer (ITS) sequence from this roundworm and analyzed their homology and phylogeny. The amplified ITS sequence length was 1140 bp, comprising the complete ITS1, 5.8S, and ITS2 sequences and a partial 28S sequence. The ITS1+ sequence was homologous (85.8% homology) to the related species Ophidascaris robertsi. The phylogenetic tree revealed a close genetic distance between O. baylisi and O. robertsi, which formed a separate branch within family Ascaridae clade. The results indicated that the identified ITS sequence could be a good molecular marker for further study on the molecular classification and genetic variation of Ophidascaris species.
