background and objectives: diagnosis of avian tuberculosis by conventional culture method is still considered as the “gold standard” technique. the main objective of this study was to compare growth of mycobacterium avium subsp. avium on four specific mycobacterial cultures such as glycerinated lowenstein-jensen medium, pyruvate-enriched lowenstein- jensen medium, mycobactin j-supplemented herr...

Recently, misuse or overuse of antibiotics has led to the antibiotic resistance problem, a global healthcare problem. Most virulence factors and biofilm formation in Pseudomonas aeruginosa are controlled by quorum sensing (QS). The inhibition QS system inhibitor molecules been suggested as novel alternative antivirulence approach which no need kill bacteria. In present study, inhibitory potenti...

The effects of drought simulated via osmotic stress induced by polyethylene glycol (PEG) in the growing medium were examined on two Wild cherry (Prunus avium L.) clones (6A and 8A) based thirteen morphometric, physiological, biochemical traits. shoot tips exposed to PEG concentrations (20 50 g L-1) designed for micropropagation with axillary buds. results showed that all morphological physiolog...
