New policies achieved during the past months, are now affecting the perfomance and competitiveness of industries as well as equipment designers and manufacturers. Natural gas (NG) consumption has been increased, and therefore, new technologies have been incorporated to chemical and manufacturing process. This study presents how policies governmental regulations and decrees, and technological tr...

A survey on myxosporean parasites of freshwater fishes from Mesopotamian part of Iran (south western part of the country, Khuzestan Province) was carried out. Some 280 individuals belonging to 14 different species were examined the prevalence of myxosporean parasites, morphology of the spores, plasmodial development, the infective site, and characteristics of the cyst location using the histolo...

Myxobolus cerebralis is the causative agent of whirling disease in salmonid fishes. In 2016, this invasive parasite was detected Alberta, Canada, for first time, initiating a comprehensive 3 yr monitoring program to assess where had spread within province. As part program, qPCR-based test developed facilitate detection environmental stages M. and from oligochaete host, Tubifex tubifex. During ~...

We used a quantitative genetics approach and estimated broad sense heritability (h2b) of myxospore count and the number of genes involved in myxospore formation to gain a better understanding of how resistance to Myxobolus cerebralis, the parasite responsible for whirling disease, is inherited in rainbow trout Oncorhynchus mykiss. An M. cerebralis-resistant strain of rainbow trout, the German R...
