when you need to know what the organism is, ex if the bacteria has a hx of resistance to antibiotics, you may want a narrower, more efficient spectrum antibiotic. a cx can give definite ID of organism within 24 hrs, which helps with initial therapy and antibiotic susceptibility tests can be done within 48 hrs as well. microbiological assessment can be continued for duration of tx, our own normal flora may carry antibiotic resistance genes that can be passed on to the pathogen.
The Iditarod Trail, also known historically as the Seward-to-Nome Mail Trail, refers to a thousand-plus mile (1,600 km) historic and contemporary trail system in the US state of Alaska. The trail began as a composite of trails established by Alaskan native peoples.
A team preparing for the Iditarod usually covers 2,000 to 3,000 miles (3,219 to 4,828 km) before the race. Since dogs can only pull a sled over snow and ice, mushers training on dry land use an all-terrain vehicle in place of a sled. Mushers work to get themselves in good physical condition before a race, too. They may need to run behind the sled at certain points in the race, and the frigid conditions on the trail can take a toll on their bodies, so being physically fit is an advantage.
