Here again, much of the blame can be laid to human activity. Antibiotic-resistant bacteria, for example, are largely a human creation. Miracle drugs such as penicillin and tetracycline have been so overprescribed and then misused by patients that they have encouraged the bugs to develop immunities. The result is infections that are nearly impossible to treat. One deadly microbe, a type of staph that often causes postsurgical infections in hospitals, can now be attacked with only one antibiotic, vancomycin...
Often packed into the bodies of ticks, below, no bigger than the head of a pin are bacteria that cause flu-like symptoms in 100,000 Americans each year. The best-known illness is Lyme disease, which, left untreated, can lead to arthritis, paralysis of facial nerves and meningitis. Antibiotics are the standard treatment. Another tick-borne disease, human granulocytic ehrlichiosis, caused by a particularly aggressive bacterium identified in 1994, can result in death if tetracycline treatment does not start early enough. Trials of a preliminary vaccine for Lyme disease began in 1992, and will end later this year...
