Acute Exposure to Glyphosate Herbicide Affects Oxidative Parameters in Piava (Leporinus obtusidens)

Archives of Environmental Contamination and Toxicology, 2011
In recent years, commercial glyphosate herbicide formulations have been widely used in agriculture to control aquatic weeds. These pesticides may result in disruption of ecological balance, causing damage to nontarget organisms including fish. Teleostean fish (Leporinus obtusidens) were exposed to commercial glyphosate herbicide formulation at 0 ...

Cytogenetics of the Genus Leporinus (Pisces, Anostomidae). II. Molecular Cytogenetics, Organization and Evolutionary Conservation of a Chromosome-Specific Satellite DNA from Leporinus obtusidens

Chromosome Research, 1997
A chromosome-specific satellite DNA from the South American fish species Leporinus obtusidens has been isolated and characterized. Sequence analysis and Southern hybridization studies indicate that the cloned 483-bp fragment is 60% AT rich and appears to comprise two diverged monomers.

Exposure to sublethal concentrations of Zn(II) and Cu(II) changes biochemical parameters in Leporinus obtusidens

Chemosphere, 2007
The aim of the present study was to assess the effect of the exposure of Leporinus obtusidens (Piava) to zinc and copper on catalase activity in the liver, delta-aminolevulinate dehidratase (delta-ALA-D) activity in liver, muscle, brain and kidney, and thiobarbituric reactive species (TBARS) in brain, muscle and liver.

Effects of four rice herbicides on some metabolic and toxicology parameters of teleost fish (Leporinus obtusidens)

Chemosphere, 2007
Effects of different herbicides on acetylcholinesterase (AChE), catalase and TBARS formation in teleost fish (Leporinus obtusidens) were studied. Fish were exposed during 30 days at concentrations of herbicides used in rice field. AChE activity in the brain decreased significantly after exposure to the herbicides clomazone and quinclorac. However, AChE

Herbicide Formulation with Glyphosate Affects Growth, Acetylcholinesterase Activity, and Metabolic and Hematological Parameters in Piava (Leporinus obtusidens)

Archives of Environmental Contamination and Toxicology, 2010
The teleost fish Leporinus obtusidens (piava) was exposed to different concentrations of Roundup, a commercial herbicide formulation containing glyphosate (0, 1, or 5 mg L(-1)), for 90 days. Acetylcholinesterase (AChE) activity was verified in brain and muscle.

Morphology and 18S rDNA sequencing identifies Henneguya visibilis n. sp., a parasite of Leporinus obtusidens from Mogi Guaçu River, Brazil

Parasitology Research, 2013
During a survey of myxozoan parasites of freshwater fish from the Mogi Guaçu River in São Paulo State, Brazil, plasmodia of Henneguya visibilis n. sp. were found on the fins of Leporinus obtusidens (Characiformes: Anostomidae). The plasmodia, which were observed on five out of eight (62.5%) L. obtusidens examined, were 400-1,000 μm long.
