A Case of Spontaneous Streptococcus Salivarius Meningitis
This article discusses Streptococcus salivarius meningitis in a 39-year old woman. She was admitted to the hospital for general fatigue, headache, and fever. Cerebrospinal fluid analysis revealed leukocytosis and cultures were positive for Streptococcus salivarius. Streptococcus salivarius meningitis is rare and has been documented to be associated with procedures involving the spinal column su...
متن کاملPeculiarities of the DNA of MM1, a temperate phage of Streptococcus pneumoniae.
The abundant presence of temperate phages in the chromosomes of clinical isolates of Streptococcus pneumoniae has been well documented. The genome of MM1, a temperate phage of pneumococcus, has been isolated as a DNA-protein complex. The protein is covalently bound to the DNA, was iodinated in vitro with Na125I, and has an Mr of 22,000. Electron microscopy and enzymatic analyses revealed that t...
متن کاملcadDX operon of Streptococcus salivarius 57.I.
A CadDX system that confers resistance to Cd(2+) and Zn(2+) was identified in Streptococcus salivarius 57.I. Unlike with other CadDX systems, the expression of the cad promoter was negatively regulated by CadX, and the repression was inducible by Cd(2+) and Zn(2+), similar to what was found for CadCA systems. The lower G+C content of the S. salivarius cadDX genes suggests acquisition by horizon...
متن کاملIdentification of Streptococcus bovis and Streptococcus salivarius in clinical laboratories.
Streptococci identified as Streptococcus bovis, S. bovis variant, and Streptococcus salivarius were examined with respect to physiological and serological characteristics and cellular fatty acid content. Similarities in physiological reactions and problems encountered in serological analysis were noted, suggesting that an expanded battery of physiological tests is needed to definitively identif...
متن کاملDual functions of Streptococcus salivarius urease.
A urease-deficient derivative of Streptococcus salivarius 57.I was constructed by allelic exchange at the ureC locus. The wild-type strain was protected against acid killing through hydrolysis of physiologically relevant concentrations of urea, whereas the mutant was not. Also, S. salivarius could use urea as a source of nitrogen for growth exclusively through a urease-dependent pathway.
