A variety of bacterial species play a major role in appendicitis. Both aerobic and anaerobic gram positive and gram negative bacteria such as, Bacteroides fragilis, Streptococcus species, Escherichia coli, Klebsiella species and Citrobacter freundii cause appendicitis. Appendicitis is usually polymicrobial. The case assumes importance because of single aetiological agent i.e. unimicrobial and n...

The close phylogenetic relationship of the important pathogen Streptococcus pneumoniae and several species of commensal streptococci, particularly Streptococcus mitis and Streptococcus pseudopneumoniae, and the recently demonstrated sharing of genes and phenotypic traits previously considered specific for S. pneumoniae hamper the exact identification of S. pneumoniae. Based on sequence analysis...

BACKGROUND Streptococcus pneumoniae is a major human pathogen. The emergence of penicillin resistant strains since the 1970s has been life threatening and the evolution of the bacteria have enabled itself to develop resistance to many other antibiotics such as the macrolides and the fluoroquinolones. This study aims to characterize S. pneumoniae isolates for the presence of penicillin and macro...

Invasive infection of multidrug-resistant Streptococcus pneumoniae is a serious clinical concern. Here, we report the complete genome sequence of a multidrug-resistant S. pneumoniae serotype 19F strain isolated from a patient with an invasive infection in Sapporo, Japan.

Streptococcus pneumoniae (S. pneumoniae) is a significant human bacterial pathogen and the major cause of pneumonia. In the post-antibiotic era, S. pneumoniae endocarditis is rare but carries a high risk of central nervous system (CNS) involvement. We present a case of invasive S. pneumoniae infection, which led to a cardioembolic stroke in a young man from septic emboli. Diagnosing a dissemina...

Streptococcus pneumoniae is a primary cause of bacterial infection in humans. Here, we present the complete genome sequence of S. pneumoniae strain A026, which is a multidrug-resistant strain isolated from cerebrospinal fluid.

The usefulness and reliability of partial sequence analysis of the manganese-dependent superoxide dismutase gene (sodA), autolysin (lytA) gene amplification and species-specific PCR based on the D-alanine:D-alanine ligase (ddl) gene for differentiating each member of the mitis group of the genus Streptococcus was investigated. On the phylogenetic tree based on sodA partial sequences (366 bp) fr...

Azithromycin is broad spectrum macrolide antibiotic with long half life and excellent tissue penetration. an azalide antimicrobial agent active in vitro major pathogens responsible for infectious of the respiratory tract, skin soft children. In children azithromycin usually given as either a 3- day course 10 mg/kg/day on first day,followed by 5 further 4 days. subclass microlide antibiotics. It...
