Since their discovery, antimicrobial drugs have proved remarkably effective for the control of bacterial infections. However, it was soon evident that bacterial pathogens were unlikely to surrender unconditionally, because some pathogens rapidly became resistant to many of the first effective drugs.

Annual Review of Pharmacology and Toxicology, 1992
Infection with human immunodeficiency virus (HIV) is a chronic process with persistent, high rates of replication. The virus exhibits high rates of mutation over time within the same individual. It is thus not surprising that drug-resis tant mutants of HIV emerge under the selective pressure of prolonged chemotherapy, especially with the knowledge of ...

DRUG RESISTANCE IN TUBERCULOSIS
Infectious Disease Clinics of North America, 1997Drug-resistant tuberculosis remains a worldwide problem. New laboratory methods have improved our ability to more rapidly identify resistant strains, but the most effective approach is to prevent the appearance of resistance by appropriate choice of antibiotics and directly-observed therapy.

Resistance to Castration – Resistance to Drugs
2013Up to 70 % of newly diagnosed patients with advanced prostate cancer (PCa) will progress to castration-resistant prostate cancer (CRPC) and, in most cases (from 50 to 70 %), will develop hematogenous bone metastasis. Once PCa cells spread to the skeleton, cancer-related death becomes inevitable, with a death burden of more than 28,000 cases in 2012, in

Trends in Pharmacological Sciences, 1989
Recently the first report of zidovudine-resistant human immunodeficiency virus obtained from AIDS patients was published. Resistance to antiviral agents may result from single point mutations in the virus genome. Several mechanisms of resistance have already been elucidated at the biochemical level but the clinical significance of drug resistance is ...

This chapter provides an overview of our current understanding of the mechanisms associated with the development of antimicrobial drug resistance, international differences in definitions of resistance, ongoing efforts to track shifts in drug susceptibility, and factors that can influence the selection of therapeutic intervention. The latter presents a

Trends in Microbiology, 1994
The mechanisms of action of antiviral drugs and of drug resistance are known in remarkable detail, partly because X-ray crystallographic structures are known for many target viral proteins. Resistance usually involves amino acid substitutions in the target protein that prevent drug binding or prevent an enzyme from accepting the drug as a substrate ...

Drug resistance is an ever present, dark shadow of cancer chemotherapy. Resistance developing as a consequence of treatment with cancer chemotherapeutic agents was a phenomenon recognized at the outset. In the days when the genome was generally considered to be static or fixed, tumor-cell drug resistance occurring in the patient, in animal models, and ...

Endeavour, 1984
Abstract Since it was introduced into Europe from South America by the Jesuits at the beginning of the 17th century, quinine has been one of the most effective drugs for the treatment of malaria. During this century a number of synthetic antimalarial drugs have been introduced but while these have had considerable success their extensive and ...

Drug resistance in ostertagiasis
Veterinary Parasitology, 1988Benzimidazole- and levamisole-resistant Ostertagia circumcincta from sheep have been reported from several countries, but there are no reports of anthelmintic-resistant O. ostertagi in cattle, where resistance has been confirmed in controlled trials.
