The realization of the photo-electrochemical process consists in percolating the solution to be treated through an electrolytic reactor, in which the anodes coated with metal oxides remains under the effect of ultraviolet radiation (UV). The solution used in this study was contaminated artificially from fecal samples positive for bacteria and intestinal parasites. The evaluation of the process for the disinfection of water was held in photo-electrical-chemical reactor, with a total volume of 10.0 Lper batch system contaminated with human fecal material. It was used as the -1supporting electrolyte solution of sodium perchlorate at 0.1 mol. Land applying a current density -1of 14 mAwith the aid of a source and a flow rate of 250 L.h. The UVradiation was provided by a mercury vapor lamp of 55 Wwithout bulb shield. The center electrode is inserted through a quartz bulb. Samples were analyzed...

The difficulty in identifying some species of Lambaris comes from very similar phenotypic feature that often result from hybridization. The parasites can be indicative of various aspects of the biology of their hosts, including phylogeny, because some groups of parasites may have host specificity. The objective was to evaluate the genetic diversity and parasitology of the fish Astyanaxaff.bimaculatus. in ponds and streams adjacent to fish farms located in the Lower São Francisco, Sergipe, Brazil. The specimens were collected in the municipalities of Propriá and Neópolis and necropsied in the search for metazoan parasites. Sections of muscle tissue were taken for DNAextraction. The samples were subjected to PCR and electrophoresis with the products of the reactions. Subsequent cluster analysis was performed. Atotal of 102 fish were infected with Lernaeacyprinaceaand Dolopssp. on the bo...
