Myelitis tract. Studies have shown respiratory tract infections within 4–39 days prior to the onset of transverse myelitis. Or, tuberculosis, syphilis, and brucellosis are also known to cause myelitis in immune-compromised individuals. Myelitis is a rare manifestation of bacterial infection. Fungi have been reported to cause spinal cord disease either by forming abscesses inside the bone or by granuloma. In general, there are two groups of fungi that may infect the CNS and cause myelitis - primary and secondary pathogens. Primary pathogens include the following: "Cryptococcus neoformans", "Coccidioides immitis", "Blastomyces dermatitides", and "Hystoplasma capsulatum". Secondary pathogens are opportunistic agents that primarily
Composition of the human body are averages of different numbers reported by different references. The adult human body averages ~53% water. This varies substantially by age, sex, and adiposity. In a large sample of adults of all ages and both sexes, the figure for water fraction by weight was found to be 48 ±6% for females and 58 ±8% water for males. Water is ~11% hydrogen by mass but ~67% hydrogen by atomic percent, and these numbers along with the complementary % numbers for oxygen in water, are the largest contributors to overall mass and atomic composition figures. Because of water content, the human body
