Resistance Mechanism of Chloramphenicol in Streptococcus haemolyticus, Streptococcus pneumoniae and Streptococcus faecalis [PDF]
Microbiology and Immunology, 1977 AbstractThe chloramphenicol resistance of Streptococcus haemolyticus, Streptococcus pneumoniae and Streptococcus faecalis isolated from clinical materials was proved to be due to an inactivating enzyme produced by these bacteria. The inactivated products of chloramphenicol were identified as 1‐acetoxy, 3‐acetoxy and 1,3‐diacetoxy derivatives by thin ...

Evaluation of matrix-assisted laser desorption ionisation time-of-flight mass spectrometry (MALDI-TOF MS) for the Identification of Group B Streptococcus. [PDF]
, 2019 Objective Group B Streptococcus (GBS) is a leading cause of neonatal meningitis and sepsis worldwide. Intrapartum antibiotics given to women carrying GBS are an effective means of reducing disease in the first week of life.

Colon‐Targeted Natural Polysaccharide‐Berberine Armored Hydrogel for the Treatment of Colitis
Advanced Healthcare Materials, EarlyView.In this research, a novel hydrogel system targeting the colon is developed, incorporating Rhubarb polysaccharides and berberine‐loaded dendrimer. This hydrogel, forms through intermolecular hydrogen bonding and electrostatic interactions, accumulates in colonic tissues, effectively alleviating pathological immune hyperactivation while modulating gut ...

Nonencapsulated Streptococcus pneumoniae: Emergence and Pathogenesis
mBio, 2016 While significant protection from pneumococcal disease has been achieved by the use of polysaccharide and polysaccharide-protein conjugate vaccines, capsule-independent protection has been limited by serotype replacement along with disease caused by ...

Studies of bacteriophages induced from Streptococcus cremoris strain R1 : is R1 a double Lysogen? : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Genetics at Massey University, New Zealand [PDF]
, 1979 Early studies on Streptococcus cremoris strain R₁ suggested that it was polylysogenic. Later, it was reported that its induced lysates contained bacteriophages (phages) of two types which were believed to differ in their morphology, buoyant densities ...

Competence in Streptococcus pneumoniae and Close Commensal Relatives: Mechanisms and Implications
Frontiers in Cellular and Infection Microbiology, 2019 The mitis group of streptococci comprises species that are common colonizers of the naso-oral-pharyngeal tract of humans. Streptococcus pneumoniae and Streptococcus mitis are close relatives and share ~60–80% of orthologous genes, but still present ...

Streptococcus anginosus ("Streptococcus milleri"): the unrecognized pathogen [PDF]
Clinical Microbiology Reviews, 1988 "Streptococcus milleri" is an unofficial name that has been applied to a group of streptococci which, although basically similar, show various hemolytic, serological, and physiological characteristics. The species name Streptococcus anginosus has recently been recognized as the approved name for these organisms. Streptococci known as "S.
