This Concept Map, created with IHMC CmapTools, has information related to: LAB 16 neisseria mycobacteria anaerobes infections, meningococcal (epidemic) meningitis infections In about 15% of these individuals, the organism invades the blood and disseminates, leading septicemia and from the there may cross the blood-brain barrier causing meningitis., Bacteroides fragilis habitat and infections The most common cause of anaerobic infections in humans. It is also a predominant organism of the normal human intestinal tract. It mainly causes anaerobic wound infections., Neisseria meningitidis infection meningococcal (epidemic) meningitis, THE MYCOBACTERIA examples Mycobacterium leprae, Neisseria gonorrhoeae frequency approximately 2,000,000 cases per year in the U.S., Mycobacterium tuberculosis infection tuberculosis, Mycobacterium tuberculosis frequency Approximately 20,000 new cases of tuberculosis a year in the U.S.; worldwide, there are over 8,800,000 new cases of tuberculosis each year and nearly 3,000,000 deaths., OBLIGATE ANAEROBES examples Bacteroides fragilis, Neisseriae, Mycobacteria, and obligate anaerobes organisms THE MYCOBACTERIA, Mycobacterium leprae frequency rare, THE NEISSERIAE microscopic appearance Gram-negative diplococci, Mycobacterium leprae infection leprosy, gonorrhea types of infection In 1% - 3% of infected women and a lower percentage of infected males, the organism invades the blood and disseminates, causing a rash, septic arthritis, endocarditis, and/or meningitis., THE MYCOBACTERIA microscopic appearance acid-fast bacilli, Neisseria meningitidis frequency between 2000 and 3000 cases per year in the U.S., THE MYCOBACTERIA examples Mycobacterium tuberculosis, meningococcal (epidemic) meningitis infections N. meningitidis infects the nasopharynx of humans causing a usually mild or subclinical upper respiratory infection in about 85% of those infected., Neisseriae, Mycobacteria, and obligate anaerobes organisms OBLIGATE ANAEROBES, Neisseria gonorrhoeae infection gonorrhea, THE NEISSERIAE examples Neisseria meningitidis
