Acipenser stellatus (stellate sturgeon) represents a sturgeon species of great importance for the scientific community and fishermen that has been intensively captured for decades. Besides of overfishing and poaching, their reproduction sites have been destroyed and their natural habitats were affected by pollution. In consequence, wild populations of stellate sturgeon have decreased dramatical...

Day-old chicks from 3 hatcheries were placed on bedding paper and brought to a commercial broiler farm between January and July 2016. Sixty-six samples of the paper, which were stained with meconium droppings of the chicks, were collected and examined for isolation of cephalosporin-resistant Enterobacteriaceae. Cefotaxime (CTX)-resistant Klebsiella pneumoniae (1 isolate) and Enterobacter cloaca...

This experiment was one part of a larger study investigating problems of aggression towards females by male broiler breeder fowl. To investigate causal mechanisms, we were interested in determining (1) if feed-restriction during rearing affects behaviour towards females at sexual maturity and (2) if aggressiveness towards females is correlated with general levels of aggressiveness. We compared ...

with the complexity and amount of information in a wide variety of comparative performance reports in poultry production, making a decision is difficult. this problem is overcomed only when all data can be put into a common unit. for this purpose, five different decision making analysis approaches including  maximin, equally likely, weighted average, ordered weighted averages and technique for ...

Cultivar of roses (Rosa spp.) has been grown in greenhouses in Qazvin region of Iran for local markets. Agrobacterium tumefaciens strains were isolated and identified from six different samples of roses plants imported from the Netherland to Iran. During August and September of 2012, nearly 2-5% of rose plants in two different greenhouses in the province of Qazvin were observed with crown gall ...

Reoviruses are important pathogens responsible for poor growth performance and silent losses in the poultry industry. They are associated with many disease and syndromes such as malabsorption (runting and stunting syndrome), respiratory diseases and immunosuppression. Broiler birds are most susceptible to viral infections during the early post hatching period. Therefore, the transfer of materna...

The objectives of the present study were the subtyping of Campylobacter jejuni subsp. jejuni strains obtained from humans and different animal species using PCR-RFLP, and the detection, by means of the same technique, of strains related to serotype PEN O19:LIO 7, the main C. jejuni serotype linked to Guillain-Barré Syndrome (GBS). Seventy C. jejuni strains isolated from human feces (n=33), prim...

Broiler flocks often become infected with Campylobacter and Salmonella, and the exact contamination routes are still not fully understood. Insects like darkling beetles and their larvae may play a role in transfer of the pathogens between consecutive cycles. In this study, several groups of beetles and their larvae were artificially contaminated with a mixture of Salmonella enterica serovar Par...
