Cercospora leaf spot (CLS) epidemics in sugar beet have been increasing in recent years causing higher use of fungicides. Concomitantly, the availability of effective fungicides is at risk because of resistance development in the fungus, the lack of new active ingredients as well as restrictive approval practices. A key option for an integrated management of CLS is cultivation of resistant vari...

The Russian wheat aphid, Diuraphis noxia (Mordvilko) (Hemiptera: Aphididae), causes severe damage to barley, Hordeum vulgare L. (Poales: Poaceae), in the highlands of Ethiopia. Little information is available on the control of this pest in Ethiopia. An experiment aimed at evaluating the resistance of barley varieties from the USA to D. noxia populations and determining biotypic variation betwee...

BackgroundShorter but effective tuberculosis treatment regimens would be of value to the community. High-dose rifampicin has been associated with more rapid and secure lung sterilization may enable shorter regimens.MethodsWe randomly assigned adults who were given a diagnosis rifampicin-susceptible pulmonary 6-month control regimen, similar 4-month regimen at 1200 mg/d (study 1 [SR1]), or 1800 ...

Abstract Bacterial blight ( X. oryzae pv. ) is a serious disease in rice across the world. To better control disease, it important to understand its epidemiology and how key aspects of this (e.g. infection efficiency, spatial spread) change according environment local site conditions season), management, particular, variety resistance. explore this, we analysed data on progress resistant suscep...

background and objectives: pseudomonas aeruginosa is one of the most important causative agents of nosocomial infections especially in icu and burn units. p. aeruginosa infections are normally difficult to eradicate due to acquired resistance to many antibiotics. recent appearance of carbapenem resistant p. aeruginosa isolates is considered a major healthcare problem. the present study was cond...

background: resistance patterns among nosocomial bacterial pathogens in hospitals may vary widely from country to coun­try at any given point and within the same country over time. acinetobacter baumannii is one of the most important bacte­rium causes hospital acquired infections. therefore, surveillance of antibiotic resistance of a. baumannii is necessary, espe­cially in our country which the...

The distribution and fluconazole susceptibilities of Candida species isolated over a 5-year period were investigated. Susceptibilities were determined by using a new microtiter procedure and the National Committee for Clinical Laboratory Standards (NCCLS) proposed standard. The new method correlated well with the NCCLS proposed standard and gave very clear end points. Results indicate that ther...

The MICs and MBCs of CI-934, ciprofloxacin, difloxacin (A-56619), A-56620, norfloxacin, enoxacin, amifloxacin, and coumermycin were determined for 43 clinical isolates of Enterococcus faecalis known to be resistant to penicillin-aminoglycoside synergy. Results were compared with those obtained for 37 synergy-susceptible E. faecalis and 22 Enterococcus faecium strains. Although no substantial di...
