Intracranial abscesses are rare complications of Streptococcus pneumoniae infections, and to our knowledge, there have been no case reports of post-infectious vasculitis developing in such patients. Here we describe the case of a 48-year-old post-splenectomy male who developed post-infectious vasculitis following S. pneumoniae otitis media complicated by mastoiditis, osteomyelitis, meningitis, ...

Resistance to peptide deformylase inhibitors in Escherichia coli or Staphylococcus aureus is due to inactivation of transformylase activity. Knockout experiments in Streptococcus pneumoniae R6x indicate that the transformylase (fmt) and deformylase (defB) genes are essential and that a def paralog (defA) is not. Actinonin-resistant mutants of S. pneumoniae ATCC 49619 harbor mutations in defB bu...

Counter immuno electrophoresis was done on concentrated urine samples of 166 children with lower respiratory tract infection for the detection of Streptococcus pneumoniae and haemophilus influenzae type b antigens. About 101⁄4 cases showed the presence of Strept. Pneumoniae Polysaccharide antigen and1.8% H. influenzae antigen. No growth was seen on blood culture in 91.8% while 0.8% showed Strep...

Over six months 10 biochemically and physiologically atypical strains of Streptococcus pneumoniae were isolated from eye swabs. Conventional methodology showed that these strains possessed characteristics of both S pneumoniae and other alpha haemolytic streptococci. The use of sodium dodecyl sulphate - polyacrylamide gel electrophoresis (SDS-PAGE) enabled us to characterise these strains as S p...

results the number of s. pneumoniae isolates resistant to benzylpenicillin, imipenem, oxacillin and ceftazidime were 94.5%, 100%, 100%, and 21.8%, respectively. analysis of mutation in the genes for pbp showed that 85% of isolates had mutations in pbp2x, pbp2b and pbp1a. susceptibility to benzylpenicillin was decreased once the number of mutated pbp genes in s. pneumonia increased. according to...

The aim of the present research was focused on the antibacterial, preliminary phytochemical and pharmacognostical properties of Vicoa indica (L.)DC. via in vitro approach. The aqueous and organic solvent (hexane, chloroform and methanol) extracts from the leaves of Vicoa indica (Asteraceae) were tested against Escherichia coli, Klebsiella pneumoniae, Salmonella typhi, Vibrio parahaemolyt...
