In elasmobranchs, blood cells originate from the thymus, spleen, and two organs associated with gonads esophagus: epigonal Leydig (LO), respectively. LO parenchyma, various granulocyte types, thrombocytes, lymphocytes were observed, notable species-specific diversity. Cells of in catshark Galeus melastomus characterized using immunohistochemistry, immunofluorescence, electron microscopy. Image analysis sections treated anti-proliferative cell nuclear antigen antibody revealed that...
ABSTRACT Freshwater ecosystems worldwide are experiencing native fish losses with severe threats to the conservation of freshwater biodiversity and ecosystem functioning, debate on whether cause is biotic or abiotic disturbance still open. Temporal variation in assemblages was analysed over an 18 year period 14 waterways lowland backwaters Po River north‐eastern Italy, which important feeding, spawning nursery sites for fish. In 1991, eight exotic species were collected. less than 20 years...
Per- and polyfluoroalkyl substances (PFAS) are resistant to breakdown now considered ubiquitous concerning contaminants. Although scientific legislative interest in these compounds has greatly increased recent decades, our knowledge about their environmental fate effects on organisms is still incomplete, especially those of the new generation PFAS. In this study, we analysed level PFAS contamination fish fauna Po River, most important waterway Italy, evaluate influence different factors...
Abstract We aimed to evaluate the effects of environmental doses perfluorooctanoic acid (PFOA) on bioconcentration and gene expression in common carp ( Cyprinus carpio ). Adult male female were exposed (200 ng/L) experimental (2 mg/L) PFOA for 56 d. Carp 200 ng/L had levels below level detection all tissue samples analyzed, whereas variable concentrations measurable various tissues from 2 mg/L. The glutathione S‐transferase (GST) gene, coding a detoxifying enzyme, increased dose‐dependent...
Plastic debris occurring in freshwater environments, which can either come from the surrounding terrestrial areas or transported upstream, has been identified as one of main sources and routes plastic pollution marine systems. The ocean is final destination land- based microplastic sources, but compared to occurrence effects microplastics ecosystems remain largely unknown. A thorough examination scientific literature on abundance, distribution patterns, characteristics environments...

Abstract Background Changes in the production of proliferating cell nuclear antigen (PCNA), a 36 kd protein involved synthesis, within intestinal epithelia can provide an early indication deviations to normal functioning. Inhibition or stimulation proliferation and PCNA be determined through immunohistochemical staining tissue. expression act as warning system changes gut this application has not been applied fields aquatic parasitology fish health.

The European perch, Perca fluviatilis L. is a common paratenic host of dioctophymatid nematodes belonging to the genus Eustrongylides. In this host, once infected oligochaetes, which serve as first intermediate are ingested, Eustrongylides migrates through intestine and frequently encountered within musculature, free body cavity, or encapsulated on viscera. current study details Italian record sp. with larvae reported in muscle P. fluviatilis. Uninfected nematode-infected tissues perch were...
Immunopathological and ultrastructural studies were carried out on the gills of bream, Abramis brama, naturally infected with copepod Ergasilus sieboldi intestine brown trout, Salmo trutta, acanthocephalan Echinorhynchus truttae. Infected showed extensive tissue damage due to attachment, including hyperplasia, as well proliferation mast cells, rodlet cells mucous cells. In parasitized more abundant than in uninfected gills. They free within lacunae, outside inside blood vessels primary...
Immunopathological and ultrastructural studies were conducted on the intestine of barbel Barbus barbus sheatfish Silurus glanis that naturally infected with acanthocephalan Pomphorhynchus laevis. Enteric helminths often cause inflammation digestive tract, inducing recruitment different types immune cells at site infection. The results our study clearly demonstrated mast (MC) dominant which occur in both hosts. MC associated fibroblasts found close proximity to, inside, capillaries intestine,...
Histochemical and ultrastructural investigations were conducted on the mucous cells of intestine brown trout, Salmo trutta L., naturally infected with cestode Cyathocephalus truncatus (Pallas, 1781) acanthocephalan Echinorhynchus truttae Shrank, 1788. A subpopulation 45 S. examined which 15 specimens harboured E. truttae, C. fish, control group, uninfected. In histological sections, hyperplasia hypertrophy evident at site parasite infection. Enhanced mucus secretion was also recorded in...
Abstract Background Among the European cyprinids, tench, Tinca tinca (L.), and pathological effects their cestodes may effect, have received very little or no attention. Most literature relating to Monobothrium wageneri Nybelin, 1922, a common intestinal cestode of for example, has focused on aspects its morphology rather than host-parasite interaction. Results Immunopathological ultrastructural studies were conducted intestines 28 collected from Lake Piediluco, which 16 specimens harboured...
