Some specific numbers regarding M. tuberculosis


Some specific numbers regarding M. tuberculosis?
I checked my islands library system and there weren't any books that focused on M. tuberculosis specifically, none that talked about its specific details. I'm hoping someone here can answer some questions. - What is the life span and life cycle of M. tuberculosis? - Is the habitat of TB just people, with no specific area in the world? - If TB is a decomposer, what does it specifically decompose if it has no set location?

M.tuberculosis does not have a life span i mean if u r talking about what is the time taken for one M.tb to divide into two then it is more than 24 hrs because to get a colony u need to wait for about5-6 weeks so basically they are slow growing bacteria n about the life cycle they usually have ony one host n that is human beings n they settle first in one's lungs n then if not treated prperly they disperse throughout ine's body n lead to miliary tuberculosis . Now low sanitation, less awareness to TB n poor economic conditions play a major role in a particular part of population is considered for TB epidemiology n for ur 3rd bit of question Mycobacterium tuberculosis is only a pathogen not a decomposer but other species under the genus mycobacterium are decomposersn some are non pathogenic like for example Mycobacterium hiberniae. Hope this helps
