Bacteriolysis by a Species of Streptomyces [PDF]

open access: yesJournal of General Microbiology, 1951
SUMMARY: The lysis of dead Bacterium coli by concentrates prepared from filtrates of a Streptomyces sp. is probably due to proteolysis. In any event the lysis can be accounted for by proteolysis, even if the action of other bacteriolytic enzymes cannot be excluded.

WhyD tailors surface polymers to prevent premature bacteriolysis and direct cell elongation in Streptococcus pneumoniae

open access: yeseLife, 2022
Penicillin and related antibiotics disrupt cell wall synthesis in bacteria causing the downstream misactivation of cell wall hydrolases called autolysins to induce cell lysis.

Induction of Bacteriolysis by Cysteamine and Its Derivatives [PDF]

open access: yesJournal of General Microbiology, 1958
Cysteamine and certain closely related derivatives induced lysis in a majority of 28 strains of Bacillus; cultures of all other genera tested were resistant. Forty-three additional sulphur and/or nitrogen containing compounds were unable to induce lysis. Optimum conditions for cysteamine activity included exposure of metabolizing post-log.

Lipopolysaccharide increases lysozyme adhesion to chitin

open access: yesJournal of Education, Health and Sport, 2019
Background. To study the effect of lipopolysaccharide on the adsorption of lysozyme on chitin.Methods. Egg white lysozyme, lipopolysaccharide and chitin were used. The lyophilized cells of M. lyzodeikticus were used as a lysozyme substrate.

Human complement regulators C4b-binding protein and C1 esterase inhibitor interact with a novel outer surface protein of Borrelia recurrentis. [PDF]

open access: yesPLoS Neglected Tropical Diseases, 2010
The spirochete Borrelia recurrentis is the causal agent of louse-borne relapsing fever and is transmitted to humans by the infected body louse Pediculus humanus. We have recently demonstrated that the B.

Bacteriolysis – a mere laboratory curiosity?

open access: yesCritical Reviews in Microbiology, 2018
The role of bacteriolysis in the pathophysiology of microbial infections dates back to 1893 when Buchner and Pfeiffer reported for the first time the lysis of bacteria by immune serum and related this phenomenon to the immune response. Later on, basic anti-microbial peptides and certain beta-lactam antibiotics have been shown not only to kill ...

A Single-Domain Antibody Targeting Complement Component C5 Acts as a Selective Inhibitor of the Terminal Pathway of the Complement System and Thus Functionally Mimicks the C-Terminal Domain of the Staphylococcus aureus SSL7 Protein

open access: yesFrontiers in Immunology, 2018
The complement system is an efficient anti-microbial effector mechanism. On the other hand abnormal complement activation is involved in the pathogenesis of multiple inflammatory and hemolytic diseases.
