Keratitis 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 کاملLactoferrin-binding proteins in Shigella flexneri.
The ability of Shigella flexneri to interact with lactoferrin (Lf) was examined with a 125I-labeled protein-binding assay. The percent binding of human lactoferrin (HLf) and bovine lactoferrin (BLf) to 45 S. flexneri strains was 19 +/- 3 and 21 +/- 3 (mean +/- standard error of the mean), respectively. 125I-labeled HLf and BLf binding to strain M90T reached an equilibrium within 2 h. Unlabeled ...
متن کاملShigella flexneri sepsis in an infant.
Shigellosis continues to be an important public health problem in developed countries, since communication in the world village has become more frequent. In addition, this disease is difficult to be prevented because only a small number of bacteria are required to cause infection, and it has exhibited steady trends towards multiple drug resistance. This report describes a 7-month-old female inf...
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.
متن کاملtmRNA Is Essential in Shigella flexneri
Nonstop mRNAs pose a challenge for bacteria, because translation cannot terminate efficiently without a stop codon. The trans-translation pathway resolves nonstop translation complexes by removing the nonstop mRNA, the incomplete protein, and the stalled ribosome. P1 co-transduction experiments demonstrated that tmRNA, a key component of the trans-translation pathway, is essential for viability...
