Nineteen safflower genotypes (Carthamus tinctorius L.) that originated from different geographical regions were screening for their response to infection with Macrophomina phaseolina, the charcoal rot pathogen at the research farm of Gorgan University of Agricultural Sciences and Natural Resources, Gorgan, Iran, in 2005. The plants were evaluated for length and width of necrotic lesion at the e...

Background: Vancomycin (glycopeptide)-resistant enterococci (VRE or GRE) can cause serious problems for hospitalized patients due to the limited options for treatment of VRE infections. As infection with VRE increases in hospitals, further knowledge about vancomycin resistant genes is needed. Methods: Isolates of Enterococcus spp. were collected from hospitalized patients in Tehran (Iran) durin...

BACKGROUND The importance of the C-C chemokine receptor type 5 (CCR5) in HIV infection and disease progression was recognized with the discovery of the Δ32 allele. Individuals homozygous for this mutation lack functional CCR5, and are almost completely resistant to HIV infection. Heterozygous individuals display decreased cell surface CCR5, which slows disease progression. Phenotypic expression...

<p>The resistance in seedling and adult plant of 13 varieties 37 lines oats against stem rust caused by <em>Puccinia graminis</em> f. sp. <em>avenae</em> was evaluated. TNQ TFQ races isolates AMEX18.21.1.1 AMEX18.18.1.1 for evaluation; isolate plants were used. The Diamante, Menonita, Karma Turquesa resistant to the race, but susceptible AMEX18.18.1.1, other two is...

conclusions the results of this study illustrated the persistence of resistant bacteria in the environment, and highlight the reservoir of resistance, associated with use of antibiotics, as feed additive in poultry production. results out of the 55 mrsa strains, all isolates were at least resistant to penicillin, 58% showed resistance to erythromycin and 55% were resistant to ciprofloxacin. on ...

The aim study antibacterial effects of silver nanoparticles against resistant strains of E.coli bacteria.12 strains of E. coli strains arising urinary infection were isolated from hospitalized patient in zabolhospitals. Minimum inhibitory concentration of winter cherry were determined by dilution method in various concentration on bacteria. The highest MIC values was found to be 100ppm against ...

Staphylococcus pseudintermedius (SP) and methicillin-resistant SP (MRSP) is one of the most important veterinary pathogens in dog. Herein, from a total 126 S. pseudintermediusstrains, 23 MRSP (18%) were identified. Multi-Locus Sequence Typing (MLST) revealed that strains belonged to ST71 (26%), which have been already reported Italy other countries. Interestingly, nine new sequence types (39%),...

Mupirocin MICs and mupA presence were determined in 108 staphylococci causing prosthetic joint infection. Zero of 35 isolates (0%) of methicillin-susceptible Staphylococcus aureus, 4/15 (27%) methicillin-resistant S. aureus isolates, 3/16 (19%) methicillin-susceptible coagulase-negative staphylococci, and 11/42 (26%) methicillin-resistant coagulase-negative staphylococci were mupirocin resistan...
