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
Vitreous body in the frontal parts of the eye (aqueous humour) which is continuously replenished, the gel in the vitreous chamber is stagnant. Therefore, if blood, cells or other byproducts of inflammation get into the vitreous, they will remain there unless removed surgically. These are known as floaters. If the vitreous pulls away from the retina, it is known as a vitreous detachment. As the human body ages, the vitreous often liquefies and may collapse. This is more likely to occur, and occurs much earlier, in eyes that are nearsighted (myopia). It can also occur after injuries to the eye or inflammation
