41.   Further complicating treatment is that some giardia organisms have developed resistance to Flagyl.

42.   He said the experiments suggest that the children will continue to develop resistance as a result of milder illness they suffer as a result of daytime mosquito bites.

43.   Health systems also must be better run so that the drugs are properly administered and followed up, to minimize the risk of the virus developing resistance.

44.   HIV, the virus that causes AIDS, mutates so rapidly it often develops resistance to a drug in a matter of months.

45.   Ho said he often saw resistance to the Abbott drug within months, although he confirmed that some patients had not developed resistance for six months.

46.   HIV swiftly develops resistance to drugs, forcing many people to change medications frequently.

47.   If a patient stops taking the drugs, the AIDS virus develops resistance to them, making further therapy ineffective.

48.   In addition, AIDS patients who develop resistance to the new drugs may, through sexual contact, be transmitting their resistance to others, Coates said.

49.   In addition, the study said the virus seems to develop resistance to other protease inhibitors after patients undergo a year of treatment with the Merck drug.

50.   In Type II diabetes, patients develop resistance to insulin, the hormone that controls blood sugar.
