A defining and extremely limiting trait of the Roman numeral system is that it lacks a character to designate the number 0. The system also has no way to represent negative or decimal numbers. This all goes back to the fact that Roman numerals were developed primarily to count and keep track of things for commerce. defining and extremely limiting trait of the Roman numeral system is that it lacks a character to designate the number 0.

Francisella tularensis is a common gram negative bacteria that is found throughout the United States, but is most commonly located in the central states (Missouri, Arkansas, Illinois, Oklahoma, Tennesee). This small microbe is the cause of a medical condition diagnosed as rabbit fever (Tularemia).
Tularemia is an epizootic infection caused by Francisella tularensis (19). Any age, sex, or race is universally susceptible to infection (12, 28, 52). Tularemia is primarily a disease of wild animals that is transmitted to humans by a contaminated environment or ectoparasites.rancisella tularensis is the etiologic agent of tularemia and, with rare exception, the only disease produced by this genus. The organism is a small, Gram-negative, pleomorphic, nonmotile, nonspore-forming coccobacillus measuring 0.2 x 0.2 to 0.7 mm.
