Lentil is a poor competitor of weeds and its sensitivity to herbicides is a major hurdle for large scale production. The present study was conducted to select herbicide resistant lentil genotypes through seed mutagenesis. Seeds of three advanced lentil genotypes (LPP 11001, LPP 11100 and LPP 11116) were treated with two different concentrations of ethyl methanesulfonate (EMS; 0.1 and 0.2%), hyd...

BACKGROUND Pyrethroid insecticides are widely utilized in dengue control. However, the major vector, Aedes aegypti, is becoming increasingly resistant to these insecticides and this is impacting on the efficacy of control measures. The near complete transcriptome of two pyrethroid resistant populations from the Caribbean was examined to explore the molecular basis of this resistance. PRINCIPA...

Introduction: Biofilm formation in Staphylococcus aureus is a major virulence factor. Both methicillin-sensitive Staphylococcus aureus (MSSA) and methicillin-resistant Staphylococcus aureus (MRSA) are common causes of community- and hospital-acquired infections and are associated with biofilm formation. The status of biofilm-forming genes has not been explored in Jordanian nasal carriers of S. ...

Recently, high resistance to pyrethroid insecticides has been associated with ineffective field treatments against Triatoma infestans (Klug) (Hemiptera: Reduviidae) in northern Argentina. Samples were collected from two areas in Argentina (Salta and La Rioja) and one are in Bolivia (Yacuiba), and they were subjected to toxicological and biochemical assays. All populations were resistant to delt...

The alteration of wild populations has been discussed as a solution to a number of humanity's most pressing ecological and public health concerns. Enabled by the recent revolution in genome editing, clustered regularly interspaced short palindromic repeats (CRISPR) gene drives-selfish genetic elements that can spread through populations even if they confer no advantage to their host organism-ar...

Combination antiretroviral therapy (cART) effectively suppresses viral load in HIV-infected individuals, but it is not a cure. Bone marrow transplants using HIV-resistant stem cells have renewed hope that cure is achievable but key questions remain e.g., what percentage of stem cells must be HIV-resistant to achieve cure?. As few patients have undergone transplants, we built a mechanistic model...

Spatial variation in parasitic infections is common, and has the potential to drive population divergence and the reproductive isolation of hosts. However, despite support from theory and model laboratory systems, little strong evidence has been forthcoming from the wild. Here, we show that parasites are likely to cause reproductive isolation in the adaptive radiation of three-spined sticklebac...

conclusions the clinical klebsiella strains isolated from lahore region, pakistan exhibited resistance to most commonly used antibiotics, which can be a serious threat to public health. the study reported some potential actinomycetes strains, which exhibit promising activity against multidrug resistant klebsiella strains. results the isolated klebsiella strains showed resistance against most of...
