Genetic dissection of drug resistance in trypanosomes
The trypanosomes cause two neglected tropical diseases, Chagas disease in the Americas and African trypanosomiasis in sub-Saharan Africa. Over recent years a raft of molecular tools have been developed enabling the genetic dissection of many aspects of trypanosome biology, including the mechanisms underlying resistance to some of the current clinical and veterinary drugs. This has led to the id...
متن کاملDrug Resistance
عفونت و تهاجم ارگانیسم های انگلی به بدن، عامل اصلی بیماری و مرگ انسانها از آغاز بشریت بوده است . در حقیقت بسیاری از اشکال حیات بدون غلبه بر ارگانیسم های زنده دیگر، قادر به ادامه زندگی نخواهند بود. انسانها معمولا مستعد تهاجم ارگانیسم های کوچکتری مانند کرمها، آمیب ها، قارچها، باکتریها و ویروسها هستند. این عوامل مکان خاصی را در بدن انتخاب کرده، مواد ضروری لازم برای حیات و تکثیر خود را دریافت نموده...
متن کاملMalaria drug - resistance in Iran
Introduction: Malaria is a public health problem for approximately 2.4 billion people, 40% of the world’s population, particularly in the tropical and subtropical countries. Countries in Asia, and Latin America, the islands of the South, West, and central pacific ocean are all affected. Drug resistance is the greatest challenge in combating against malaria. Drug resistance in malaria is now w...
متن کاملHigh Prevalence of Drug Resistance in Animal Trypanosomes without a History of Drug Exposure
BACKGROUND Trypanosomosis caused by Trypanosoma congolense is a major constraint to animal health in sub-Saharan Africa. Unfortunately, the treatment of the disease is impaired by the spread of drug resistance. Resistance to diminazene aceturate (DA) in T. congolense is linked to a mutation modifying the functioning of a P2-type purine-transporter responsible for the uptake of the drug. Our obj...
متن کاملModulation of mitochondrial electrical potential: a candidate mechanism for drug resistance in African trypanosomes.
Bloodstream forms of four populations of the livestock pathogen Trypanosoma congolense, isolated from different natural infections, have been shown to exhibit a wide range of sensitivities to the trypanocide isometamidium chloride (Samorin(R)). In mice the 50% curative doses (CD50) for Samorin range from 0.007 to 20 mg/kg body weight. Uptake of isometamidium chloride demonstrated Michaelis-Ment...
