Characteristics of Streptococcus pseudopneumoniae isolated from purulent sputum samples.
Streptococcus pseudopneumoniae is a recently described streptococcus that is phenotypically and genetically distinct from Streptococcus pneumoniae and other viridans streptococci. Key characteristics of S. pseudopneumoniae are the absence of a pneumococcal capsule, insolubility in bile, resistance or indeterminate susceptibility to optochin when incubated in 5% CO2 but susceptibility to optochi...
متن کاملAntimicrobial susceptibility profile of Streptococcus pseudopneumoniae isolated from sputum.
Streptococcus pseudopneumoniae is a recently described member of the Streptococcus mitis/oralis group of viridans streptococci that shares some characteristics with Streptococcus pneumoniae (1). Key characteristics of S. pseudopneumoniae are the absence of pneumococcal capsule, insolubility in bile, resistance or indeterminate susceptibility to optochin when incubated in 5% CO2 but susceptibili...
متن کاملProteases from Purulent Sputum
A procedure is described for the purification of the elastase and chymotrypsin-like enzymes from purulent sputum. This procedure permitted the isolation of 132 mg and 120 mg of the elastase and chymotrypsin-like enzymes, respectively, from 230 g of purulent sputum. The elastase enzymes consist of a family of five isozymes, and at least three isozymes comprise the chymotrypsin-like enzyme system...
متن کاملIncidence and pathogenic effect of Streptococcus pseudopneumoniae.
We evaluated the incidence of Streptococcus pseudopneumoniae in clinical isolates by phenotypic methods and DNA-DNA hybridization. The pathogenic role of this organism was investigated with the mouse peritonitis/sepsis model. Our results show a low incidence (1/120 pneumococcal isolates) and a potential pathogenic effect for S. pseudopneumoniae.
متن کاملStreptococcus pseudopneumoniae: an emerging respiratory tract pathogen
BACKGROUND & OBJECTIVES Streptococcus pseudopneumoniae a member of the Viridans Streptococci, is known to be associated with chronic obstructive pulmonary disease and respiratory tract infections (RTI). Very scanty information is available on the isolation of S. pseudopneumoniae from India. Hence, the present study was an attempt to isolate S. pseudopneumoniae from clinical samples and to study...
