  • 1 November 2009
Antibiotics are among the most successful drugs used for human therapy. However, since they can challenge microbial populations, they must be considered as important pollutants as well. Besides beingExpand

Antibiotics and Antibiotic Resistance Genes in Natural Environments
The large majority of antibiotics currently used for treating infections and the antibiotic resistance genes acquired by human pathogens each have an environmental origin. Recent work indicates thatExpand

Antibiotics as intermicrobial signaling agents instead of weapons
It has been widely assumed that the ecological function of antibiotics in nature is fighting against competitors. This made them a good example of the Darwinian struggle-for-life in the microbialExpand

Haematozoa in forest birds from southern Chile: Latitudinal gradients in prevalence and parasite lineage richness
The existence of latitudinal gradients in species richness and their abundance is known for many free living organisms but few cases have been reported for parasitic diseases. In addition,Expand

Mutation Frequencies and Antibiotic Resistance
Antibiotic resistance can be achieved by horizontal acquisition of resistance genes (carried by plasmids or transposons), by recombination of foreign DNA into the chromosome, or by mutations inExpand

Development of a framework for fire risk assessment using remote sensing and geographic information system technologies
Forest fires play a critical role in landscape transformation, vegetation succession, soil degradation and air quality. Improvements in fire risk estimation are vital to reduce the negative impactsExpand

A global view of antibiotic resistance.
Antibiotic resistance is one of the few examples of evolution that can be addressed experimentally. The present review analyses this resistance, focusing on the networks that regulate its acquisitionExpand

Functional role of bacterial multidrug efflux pumps in microbial natural ecosystems.
Multidrug efflux pumps have emerged as relevant elements in the intrinsic and acquired antibiotic resistance of bacterial pathogens. In contrast with other antibiotic resistance genes that have beenExpand

Sex chromosome linkage of 5S rDNA in rainbow trout (Oncorhynchus mykiss).
The karyotype of the rainbow trout is characterized by a primitive XX/XY sex-determining chromosomal system. (Thorgaard et al., 1977). In the present study using FISH we have physically linked the 5SExpand
