Aim Species on islands are at high risk of extinction due to environmental changes, including global warming, land-use alterations and invasions. At local scales, extinctions can be offset by strategies promoting in situ persistence. We explored how persistence-related traits plants—that is, linked belowground resource conservation, growth, size longevity—on edaphic respond variation insularity...
background and objectives: citrobacter freundii is an opportunistic pathogen causing nosocomial infections and resistant to various antibiotics. we aimed to determine the clonal relationship of c. freundii isolates using pulsed-field gel electrophoresis (pfge). materials and methods: fifty clinical isolates of c. freundii were collected from the main hospital in kermanshah. after antibiotic sus...
conclusions the inter- and intra-hospital dissemination of resistant clones is a matter of concern and is an indicator of the level of the improvement and surveillance of standard hygiene, particularly disinfection and hand washing before and after contact with patients. given the emergence of mbl-producing strains, surveillance has become an important procedure to control the transmission of r...

background acinetobacter baumannii is an opportunistic pathogen, related with nosocomial infections such as bacteremia, urinary tract infections, and ventilator-associated pneumonia. multidrug resistant (mdr) a. baumannii strains are first line causes of infection, especially in patients hospitalized at intensive care units (icus). infection with mdr a. baumannii strains has a longer duration a...
forty monoconidial isolates of magnaporthe grisea were examined, for an identification of vegetative compatibility group and a characterization of genetic diversity, using rep-pcr genomic fingerprinting. the isolates were collected from weeds digitaria sanguinalis (crabgrass), setaria italica (foxtail millet), echinochloa crus-galli (barnyard millet), and some other unknown ones during 2003 - 2...
A reciprocal transplant-replant experiment was carried out to investigate the clonal plasticity and local specialization of OAFE population (O type) and BF population (U type) of a clonal rhizome herb Iris japonica in contrasting reciprocal heterogeneous habitats on Jinyun Mountain. U Population had better performance of plant size and clonal propagation (including allocation to clonal propagat...
