background acinetobacter has become an important cause of different infections such as wound infection, due to its great ability to survive and spread in hospital settings and to develop resistance against many antibiotics. objectives the aim of this study was to investigate the antibiotic resistance among isolates of acinetobacter from wound infections during a 7-year period, from 2005 to 2011...

for development of pollinator parent resistant to powdery mildew disease of sugar beet, relatively resistant 14442 population was used. based on resistance index, 50 resisitant plants were selected to produce half sib family(h.s.f). after random pollination between these 50 plants, seed of h.s.f was harvesed. from these 50 plants, only 39 plants had produced enough seed. next year these h.s.f w...

conclusions the results showed that e. coli isolated from patients with uti had eight virulence factors with high frequencies. moreover, these results alleged a direct connection between virulence factors and antimicrobial resistance in e. coli. results the frequency of virulence factors papc, afa, sfa/foc, fimh, hly, neuc, ibea, and iucc were 53.3%, 51.7%, 53.3%, 56.7%, 23.3%, 31.7%, 20%, and ...

Background and Aims: To evaluate the effect of temperature on wheat streak mosaic virus (WSMV) resistance phenotype, through total protein, phenol, and peroxidase activity in bread wheat, a factorial experiment was conducted using Adl-Cross (resistant) and Marvdasht (susceptible) cultivars. Materials and Methods: Results showed that incubation at 32C changed the gene expression for resistance ...

conclusions these results indicated that eaec strains isolated from iranian children with diarrhea were heterogeneous and showed high resistance rates against commonly used antibiotics, which was similar to that reported in studies performed in other countries. results significant percentage of local eaec strains carried the virulence plasmid genes and formed biofilms. in addition, these strain...

ninety barley doubled haploid lines originated from crossing between six barley cultivars in cereal research department, seed and plant improvement institute, karaj, iran were evaluated for resistance to powdery mildew and some agronomic traits in field in 2007. six parent cultivars and a powdery mildew susceptible check cultivar, afzal were also included. sixty two doubled haploid lines showed...

background and objectives: heavy metals are considered as high risk biocides due to their harmful effects on human health, the environment and other living organisms. bacterial strains showing resistance to heavy metals has been used for removing such toxic materials from the environment. in this study we isolated and characterized a heavy metals-resistance halophilic bacterial strains from kal...
