Abstract The effects of pirimicarb (a neurotoxin), buprofezin (an insect growth regulator) and pymetrozine antifeedant) on Coccinella undecimpunctata were assessed by studying the survival development all immature stages reproductive performance adults. Insecticides sprayed at doses recommended manufacturers for control aphids and/or whiteflies. None three insecticides had a significant effect C. eggs. When larvae, significantly reduced to adulthood <33%, compared >45% other insecticide...
The aim of this study was to evaluate the pathogenicity Vibrio alginolyticus isolated from an outbreak sea horse Hippocampus reidi reared in State Santa Catarina, Brazil, by experimental infection. Sea horses with necrosis on mouth epithelium were collected aquaria at Aquaculture Department, UFSC and bacterium mouth, liver, heart blood tiosulphate citrate bilesalt sucrose agar broth. strains identified API 20E kit 99.1% probability as alginolyticus. Twelve adult (9.63 ± 2.42 g 15.12 0.87 cm)...
Background: Gaseous elemental mercury (Hg0 or GEM) is an atmospheric form of (Hg) – a toxic heavy metal that naturally released in volcanic environments. Research with wild mice demonstrates chronic exposure to hydrothermal environment leads the bioaccumulation Hg lungs, but also both central (CNS) and peripheric (PNS) nervous systems, marked indications neurotoxicity. Studies addressing human volcanogenic Hg0 are scarce, hence its risks still unknown. This study aims evaluate level children...
Volcanoes, during their explosive and post-explosive phases, as well through continuous degassing processes, release a range of pollutants hazardous to human health, including toxic gases, fine particulate matter, heavy metals. These emissions impact over 14% the global population living in proximity volcanoes, with effects that can persist for days, decades, or even centuries. Living conditions these regions often involve chronic exposure contaminants air, water, soil, significantly...

In pathology laboratories, several volatile organic compounds (VOCs) are used, such as formaldehyde, ethanol, and xylene. These substances recognized genotoxic cytotoxic, which is why their handling poses risks to human health. The buccal micronucleus (MN) cytome assay a non-invasive, useful, simple method detect these effects in exposed individuals. aim of the study was evaluate risk genotoxicity cytotoxicity VOCs professionals S. Miguel Island, Azores, Portugal. comprised two groups:...
Monogeneans are the parasites mostly found on body surface and gills of fish can cause large losses in farmed fish. Some studies demonstrate elevated parasitic levels causing hematological alterations. But few them relate effects parasitism hematology histopathology native freshwater This study evaluated host-parasite relationship pacu (Piaractus mesopotamicus) parasitized by monogenean Anacanthorus penilabiatus. Hematological parasitological assessments were obtained 60 captured a farm...
Microscopic and molecular procedures are used to describe a new myxosporean species, Henneguya carolina sp. nov., found infecting the intestine of marine teleost fish Trachinotus carolinus on southern Atlantic coast Brazil. Spherical ellipsoid cysts, measuring up ~750 µm, display synchronous development. Mature myxospores ellipsoidal with bifurcated caudal process. Myxospore body length, width, thickness 12.7 ± 0.8 (12.0-13.4) 8.8 0.6 (7.5-9.6) 5.8 0.4 (5.0-6.4) respectively; 2 equal...
Abstract This study evaluated the influence of clomazone herbicide (2-[(2-chlorophenyl)methyl]-4,4-dimethyl-3-isoxazolidinone) contamination on hematological parameters and histological changes in gills liver silver catfish (Rhamdia quelen) from Madre River, Santa Catarina State, Southern Brazil. Fish were collected between March 2010 January 2012 at two different sites one site receiving residual water (contaminated site) rice culture (n = 49) another that do not receive (reference 48).
