Streptococcus agalactiae, or Group-B Streptococcus is a Gram-positive nonmotile bacterium and is the leading cause of bacterial sepsis, pneumoniae and meningitidis in neonates in U.S. and Europe. It usually behaves as a commensal organism that colonizes the gastrointestinal or genital tract of 25-40% of healthy women, but it can cause life-threatening invasive infection in[..]

Staphylococcus aureus are Gram-positive nonmotile coccus that grows in aerobic and anaerobic conditions, in which it forms grape-like clusters. S. aureus is an important nosocomial and community-acquired pathogen. It produces numerous toxins including superantigens that cause unique disease entities such as toxic-shock syndrome and staphylococcal scarlet fever. Its genetic[..]

Staphylococcus aureus are facultative anaerobic Gram-positive cocci, that is a major cause of hospital acquired (nosocomial) infection of surgical wounds and infections associated with indwelling medical devices. S. aureus causes food poisoning by releasing enterotoxins into food, and toxic shock syndrome by release of superantigens into the blood stream. Over the last decade,[..]

The Group-A Streptococcus (Streptococcus pyogenes) remains an important human pathogen, associated with a range of superficial skin and throat infections as well as a variety of more serious invasive infections and autoimmune sequelae such as acute rheumatic fever and post-streptococcal glomerulonephritis (Ref.1). S. pyogenes strains are grouped into two classes on the basis of[..]

Staphylococcus epidermidis is a Gram-positive nonmotile bacterium that grows in aerobic and anaerobic conditions, in which it forms grape-like clusters. It produces numerous toxins including superantigens that cause unique disease entities and has emerged as a causative agent of infections often associated with implanted medical devices. The S. aureus and[..]

Based on differences in their compositions and the linkages of cell wall polysaccharides, Streptococci are classified into eight serotypes as follows; Streptococcus mutans (Serotypes c, e, and f), Streptococcus sobrinus (Serotypes d and g), Streptococcus cricetus (Serotype a), Streptococcus rattus (Serotype b), Streptococcus ferus (Serotype c),[..]

Streptococcus pneumoniae (also known as Pneumococcus or Diplococcus pneumoniae) is a Gram-positive coccus and is among the most significant causes of bacterial disease in humans. It is responsible for a high proportion of cases of pneumonia, acute otitis media, acute sinusitis, bacteremia and meningitis. There are 90 known serotypes of S. pneumoniae, each of which[..]
