Virulence factors in streptococcal infective endocarditis
Institute of Dental Research Westmead Millennium Institutes Westmead Centre for Oral Health PO Box 533 Wentworthville NSW 2145 Tel (02) 98458772 Fax (02) 98457599 E-mail: [email protected] Infective endocarditis (IE) is a life threatening, endovascular infection occurring when bacteria enter the blood stream and adhere to heart valves. Mortality rates remain in the range of 1127% ....
متن کاملStudies on Streptococcal Bacteriophages
Evidence has been presented that the burst size in the Group A and Group C streptococcal phage-host systems are in general similar producing approximately 13 phage particles per infected coccus. The exception was the C1 phage which produced 10 times more virus particles than all the other phages tested. The eclipse period for the A25 phage-host system was found to extend for 34 min, while the C...
متن کاملStudies on Virulence
1. An automatic apparatus is described by which a new supply of food can be furnished actively growing organisms at any desired interval of time-an automatic transferring device. 2. A single strain of pneumococcus, Type I, Neufeld, which had become avirulent for mice, acquired virulence of maximal degree when grown in the described apparatus with skimmed milk sterilized in an Arnold sterilizer ...
متن کاملStructural characteristics of potential novel virulence factors, the host cytokine binding proteins of Aggregatibacter actinomycetemcomitans
Various gram-negative pathogens possess secreted or outer membrane proteins (OMPs) which interact with host cytokines. Of periodontal pathogens only Aggregatibacter actinomycetemcomitans (Aa) has been shown to sequester and uptake cytokines. We have identified two (OMPs) of Aa, bacterial interleukin receptor I (BilRI) and OM secretin channel (OMS), which interact with several cytokines, the int...
متن کاملStudies on the Conjugation of Streptococcal Nucleoprotein*
Recent observations on conjugated proteins (l-6) raise the question as to whether the prevailing ideas concerning the nature of the attachment of nucleic acids with the proteins are valid. With certain exceptions it has generally been assumed that the nucleoproteins are salts of a polyvalent nucleic acid and a polyvalent base (protein) (7). The ideas that nucleoproteins are salt-like (polar), o...
