Streptococcal myositis as a complication of juvenile dermatomyositis.

The infection of muscle is an infrequent condition. We report on a patient with a juvenile form of dermatomyositis who developed infectious myositis caused by Streptococcus pyogenes. The inflammatory myopathy probably favoured the colonization of muscle during a bacteremia related to the skin lesions. The main forms of streptococcal myositis, which can currently be differentiated by means of imaging techniques, are discussed in addition to its treatment and prognosis.

Characterization of a 225 kilodalton rhoptry protein of Plasmodium falciparum.

A monoclonal antibody (24C6 4F12) raised against Plasmodium falciparum culture supernatant antigens gave a multiple dot picture on schizonts when assayed by immunofluorescence on P. falciparum erythrocytic stages. The corresponding antigen was localized in the peduncle of rhoptries by immunoelectronmicroscopy. On Western blots of P. falciparum schizonts, a major antigen of 225 kDa and a minor one of 240 kDa were recognized by this McAb. Pulse chase analysis of [35S]methionine biosynthetic labeling of P. falciparum culture demonstrated that the 240 kDa molecule was the precursor of the 225 kDa and that its processing occurred between 0 and 4 h after synthesis. Biosynthesis of the 240-225 kDa antigen occurred only during schizogony.
