متن کاملSporothrix schenckii and Sporotrichosis.
Sporotrichosis, which is caused by the dimorphic fungus Sporothrix schenckii, is currently distributed throughout the world, especially in tropical and subtropical zones. Infection generally occurs by traumatic inoculation of soil, plants, and organic matter contaminated with the fungus. Certain leisure and occupational activities, such as floriculture, agriculture, mining, and wood exploitatio...
متن کاملActivation of the alternative complement pathway by fungal melanins.
Melanins are complex biological pigments formed by the oxidative polymerization of phenolic and/or indolic compounds. These pigments have been implicated in the pathogenesis of some microbial infections, malignancies, degenerative disorders, and autoimmune diseases. Recent studies have demonstrated that melanins have antigenic and anti-inflammatory properties. These findings led us to further e...
متن کاملActivation of the alternative complement pathway by intraocular lenses.
To determine if posterior chamber polymethylmethacrylate lenses with polypropylene loops activate complement, the authors measured levels of C3a, C4a and C5a by radioimmunoassay in human sera incubated with and without these lenses. Human sera incubated with intraocular lenses showed elevated levels of C3a and C5a but no change in C4a. There were no statistically significant differences in the ...
متن کاملActivation of the alternative complement pathway by Naegleria fowleri.
Naegleria fowleri amoebae were lysed by adult fresh human serum, and their multiplication was inhibited in culture medium supplemented with 10% fresh human serum. Heat inactivation (56 degrees C, 30 min) of serum abrogated these lytic and inhibitory effects. Absorption of human serum with amoebae failed to reduce immunoglobulin levels, and no specific antibody was detected in untreated or treat...
