Infectious diseases and fish feeds management are probably the major expenses in the aquaculture business. Hence, it is a priority to define sustainable strategies which simultaneously avoid therapeutic procedures and reinforce fish immunity. Currently, one preferred approach is the use of immunostimulants which can be supplemented to the fish diets. Arginine is a versatile amino acid with impo...

Vaccinated, feed-trained largemouth bass fry (Micropterus salmoides floridanus) were cohabited with sham-vaccinated fish. Fish were exposed, under natural conditions, to Flavobacterium columnare, a ubiquitous bacterium associated with columnaris disease. During every time interval, the probability that a vaccinated fish would survive past time, t, was greater than for sham-vaccinated fish and s...

Conventional cytogenetic is the standard technique for detection of Philadelphia (Ph) chromosome in chronic myeloid leukemia (CML). Evaluation of abelson murine leukemia/breakpoint cluster region (abl/bcr) fusion using dual-colour fluorescence in situ hybridization (D-FISH) is an alternative approach allowing rapid and reliable detection of the disease. We employed the technique of interphase D...

Background: The prevalence of allergic diseases is increasing worldwide. The effective role of omega-3 fatty acids in the maturation of immune system and protection against atopic diseases has been well discussed. However, previous studies revealed conflicting results. This study was conducted to investigate the effect of fish oil consumption by nursing atopic mothers on the level of interferon...

Disease are recognized as one of the major constraint to sustainable animal production which can cause significant economic loss especially in aquaculture. Various chemotherapeutic agents have been traditionally used in the treatment and prevention of diseases in farmed fish but they are not recommended since improper and continuous use of antibiotics may lead to potential development of antibi...

The effects of dietary fatty acid supplementation on various disease parameters in the spontaneously autoimmune MRL-mp-lpr/lpr mouse model of systemic lupus erythematosus before onset of disease were investigated. A fat deficient diet was supplemented with the following oils: olive oil, sunflower oil, evening primrose oil (EPO), fish oil, and a fish oil/EPO mixture. The mice receiving a diet en...

background: it has been shown that serum total homocysteine (hc) is a risk factor for vascular disease which characterizes endothelial damage in the general and in the end-stage renal disease (esrd) population as well. whether n-3 polyunsaturated fatty acids decrease homocysteine (hcy) level has been a subject of controversy. methods: renal transplant patients were randomized in 2 groups and re...

Various methods have been developed to mitigate the adverse effects of the Federal Columbia River Power System on juvenile Pacific salmon out-migrating through the Columbia River basin. In this study, we found that hatchery-reared spring Chinook salmon Oncorhynchus tshawytscha in the river are in varying degrees of health, which may affect delayed mortality and the assessment of the effectivene...
