Use of monoclonal antibodies to type Shigella flexneri in Bangladesh.
A panel of 10 mouse and rat monoclonal antibodies specific for different type- and group-specific O-antigenic determinants of Shigella flexneri lipopolysaccharide was used to serotype 240 isolates of S. flexneri from Bangladesh. Three immunoglobulin M antibodies were used in a direct slide agglutination test; seven immunoglobulin G antibodies were absorbed to Staphylococcus aureus and used in a...
متن کاملImmunochemical Study of a Bacterial Endotoxin: Shigella Flexneri Type Z
The endotoxins of the Gram-negative bacteria have similar biological and chemical properties. The toxic antigen of Shigella flexneri Type Z was selected as a representative endotoxin, and it was confirmed that the antigen consists of a polysaccharide conjugated with phospholipid and protein. By the technique of zone electrophoresis, the polysaccharide of the purified endotoxin was shown to be c...
متن کاملPhage-dependent changes in Shigella flexneri type antigen synthesis.
Lysogenic conversion of Shigella flexneri type antigens was studied with the aid of wild-type and thermosensitive mutant phages. With all wild-type phages, the appearance of glycosylated antigen was accompanied by the appearance of polyprenyl phosphate glucose synthetase activity. With some of the mutant phages, the appearance of glycosylated antigen was not followed by the formation of lipid-l...
متن کاملKeratitis due to Shigella flexneri.
Multiresistant Shigella flexneri isolates were cultured from the cornea and stool of a girl. Genetic analysis showed the isolates were identical. Shigella spp. are rare causes of ulcerative keratitis; there have only been 14 published cases since 1943. Although prognosis after local treatment is good, shigellosis is a systemic infection, possibly leading to dehydration.
متن کاملChemoprophylaxis of Shigella flexneri keratoconjunctivitis in rabbits.
Chloramphenicol, chlortetracycline, streptomycin, and sulfisoxazole prevented keratoconjunctivitis in rabbit eyes infected with Shigella flexneri. The route of administration of the agent and the dose were important variables in controlling the infectious process. This assay system appears to be a useful technique for the in vivo evaluation of chemotherapeutic agents.
