Generation of reactive oxygen species by leukocytes of Prochilodus lineatus

Fish Physiology and Biochemistry, 2013
Prochilodus lineatus (curimbatá), from the Procholodontidae family, is a Brazilian freshwater fish, which is important commercially, nutritionally and ecologically. It is encountered in the Rio da Prata Bay in Southern South America. Studies on the immune system of this fish are scarce, but the physiological mechanisms of the species are analogous to ...

Water pH and Prochilodus lineatus larvae survival

Fish Physiology and Biochemistry, 2008
The present study aimed to determine the influence of water pH on survival of curimbatá, Prochilodus lineatus, larvae. Forty-five 2-l glass aquaria with artificial aeration and no water exchange were stocked at a density of 10 larvae l(-1). The pH values used as treatments were 3.7 +/- 0.0, 4.0 +/- 0.0, 4.4 +/- 0.2, 4.6 +/- 0.2, 4.8 +/- 0.2, 5.1 +/- 0 ...

Genotoxic effects of Roundup® on the fish Prochilodus lineatus

Mutation Research/Genetic Toxicology and Environmental Mutagenesis, 2008
Glyphosate-based herbicides, such as Roundup, represent the most extensively used herbicides worldwide, including Brazil. Despite its extensive use, the genotoxic effects of this herbicide are not completely understood and studies with Roundup show conflicting results with regard to the effects of this product on the genetic material.

Acute effects of diflubenzuron on the freshwater fish Prochilodus lineatus

Comparative Biochemistry and Physiology Part C: Toxicology & Pharmacology, 2008
The effects of diflubenzuron (DFB), an insecticide to control ectoparasites in fish farms, on muscle acetylcholinesterase (AChE), detoxifying and antioxidant enzymes, hematological and physiological parameters, and liver histopathology were evaluated in Prochilodus lineatus after 6, 24 and 96 h of exposure to 25 mg L(-1) of DFB.

Biomarkers of waterborne copper exposure in the Neotropical fish Prochilodus lineatus

Aquatic Toxicology, 2016
The main goal of the present study was to investigate the effects of acute exposure to copper (Cu) using a Neotropical freshwater fish as sentinel species through multi biomarkers analysis at different biological levels. Juveniles of Prochilodus lineatus were kept under control condition (no Cu addition in the water) or exposed to environmentally ...

Ultrastructural, ssrDNA sequencing of Myxobolus prochilodus and Myxobolus porofilus and details of the interaction with the host Prochilodus lineatus

Parasitology Research, 2016
Myxobolus prochilodus and Myxobolus porofilus are parasites of Prochilodus lineatus, an economically important South American fish found in La Plata and Paraiba do Sul river basins. This study focusing on parasite-host interaction provides an ultrastructural and phylogenetic analysis, the latter based on ssrDNA sequencing of these parasites ...
