Abstract
This study was carried out to determine the toxicity and biochemical and morphophysiological changes caused by Serjania erecta leaf aqueous extract in pacu (Piaractus mesopotamicus). For acute toxicity testing (CL50-4h), pacu juveniles were exposed during 4 h to Serjania erecta aqueous extract concentrations of 2.5, 12.5, 25, 50, 100, and 150 µg mL-1, which were added directly to the water in the tanks. In the control group, the animals were kept in water free from aqueous extract. CL50-4 h was estimated at 57.43 µg mL-1. After exposure to the aqueous extract, the highest (P<0.05) glucose concentration and the lowest (P<0.05) plasma sodium level were when the fish were exposed to the S. erecta concentration of 50 µg mL-1. Mortality occurred at S. erecta extract levels higher than 50 μg mL-1, and all fish died at concentrations greater than 100 μg mL-1. In addition, exposure to this extract caused severe histological changes in the gills and liver with higher prevalence of necrosis (30.2%), and fatty degeneration (77.4%) respectively. At the concentrations tested here, S. erecta aqueous extract causes morphofunctional alterations in this fish species.

Retrotransposons and multilocus sequence analysis reveals diversity and genetic variability in endophytic fungi-associated with Serjania laruotteana Cambess. Braz J Microbiol 2021; 52:2179-2192. [PMID: 34491570 DOI: 10.1007/s42770-021-00605-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2020] [Accepted: 08/30/2021] [Indexed: 11/28/2022] Open
Abstract
The composition of endophytic communities is dynamic and demonstrates host specificity; besides, they have great intra- and interspecific genetic variability. In this work, we isolated leaf endophytic fungi from Serjania laruotteana, identify them using multilocus analysis, and evaluate the genetic variability using IRAP (inter-retrotransposon amplified polymorphism) and REMAP (retrotransposon-microssatellite amplified polymorphism). A total of 261 fungi were isolated and 58 were identified. Multilocus phylogenetic analysis using the partial sequences from the ITS1-5.8S-ITS2 regions, elongation factor 1-alpha, β-tubulin, actin, glyceraldehyde-3-phosphate dehydrogenase, and calmodulin genes identify that most strains belonged to the Colletotrichum and Diaporthe genera, other isolated genera were Xylaria, Phyllosticta, Muyocopron, Fusarium, Nemania, Plectosphaerella, Corynespora, Bipolaris, and Curvularia. The IRAP and REMAP analyzes were performed with Colletotrichum and Diaporthe genera and showed 100% of polymorphism and high intra- and interspecific variability. This is the first report of the diversity of endophytic fungi from S. laruotteana. In addition, it demonstrated that the IRAP and REMAP can be used to distinguish morphologically similar lineages, revealing differences even strains of the same species.

Hepatic and gastroprotective activity of Serjania marginata leaf aqueous extract in Nile tilapia (Oreochromis niloticus). FISH PHYSIOLOGY AND BIOCHEMISTRY 2019; 45:1051-1065. [PMID: 31089991 DOI: 10.1007/s10695-019-00622-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/27/2018] [Accepted: 02/14/2019] [Indexed: 06/09/2023]
Abstract
The aim of this study was to assess the leaf aqueous extract composition of Serjania marginata and the effects of its inclusion on the diet of Nile tilapia (Oreochromis niloticus), with respect to the activity of digestive enzymes and enzymes associated with the metabolism of the liver and intestine and liver histopathology. Fish (initial mean weight, 54.36 ± 17.04 g) were divided into groups: fasting (without feeding), control (commercial feed), and treatment (commercial feed with leaf aqueous extract of Serjania marginata), and in each aquarium, there were five individuals and the fish fed ad libitum for 15 days. Treatment fish had ingested on average 224.3 mg of extract/kg of fish/day. In the extract analysis by mass spectrometry, quercitrin, isoquercitrin, A-type proanthocyanidin trimer, and quinic acid were identified. In the enzymatic activity, fish from the treatment group showed higher level of alkaline phosphatase, while the hepatotoxic markers (AST and ALT) and levels of lipase, amylase, and nonspecific protease did not differ (p > 0.05). In liver histopathological analysis, it was observed that fish from the treatment showed normal structure, while abnormalities were associated with control (fibrosis, loss of cordonal architecture, vacuolated hepatocytes with nucleus displaced to the periphery) and fasting (reduction in hepatocyte size and sinusoidal space). The intestine histopathology evidenced that the extract favored the development of goblet cells and intestinal fold height. The results indicated that the leaf aqueous extract of S. marginata assists in the structural maintenance of the liver and intestine and stimulates intestinal alkaline phosphatase production in Nile tilapia, suggesting that the identified compounds act on the liver and intestine, showing hepatoprotective effects and stimulating intestinal digestion.
