Bacteriostatic and bactericidal effects of antibiotics on Bacteroides
The bacteriostatic or bactericidal action of metronidazole, clindamycin, tetracycline, chloramphenicol, cefoxitin and penicillin were determined against sixteen Bacteroides fragilis strains and six B. thetaiotaomicron strains. Drugs were considered bactericidal when minimal bactericidal …

Molecular Basis of Peptidoglycan Recognition by a Bactericidal Gut Lectin
The mammalian gut is densely populated by varied microbial species. This relationship is mutually beneficial as long as bacteria remain corralled in the gut lumen. The epithelium is protected by the secretion of antimicrobial proteins by specialized epithelial cells in the intestinal crypts. This …

Bactericidal efficiency of a helically coiled tube turbulent flow processing system
… additional data are needed on factors affecting bactericidal efficiency of helically coiled tube heat exchange systems. More basic information is needed on flow properties, and on heat exchange characteristics of these systems. In addition to this, information on bacterial destruction is required …

The Ligand and Function of the RegIII Family of Bactericidal C-Type Lectins
… is the first example of a family of directly bactericidal C-type lectins. We also present evidence for the regulation of these bactericidal proteins by colonization with an intestinal microflora. Therefore, the research presented in this thesis elucidates the function of three members of the …

Antimicrobial Nanoparticles: A Green and Novel Approach for Enhancing Bactericidal Efficacy of Commercial Antibiotics
… (E. durans and S. bovis). Cef-GNPs exerted bactericidal action on both P. aeruginosa and E. durans by disrupting the cellular membrane resulting in leakage of cytoplasmic content and death of bacterial cell. Our investigation and results provides an additional step in the development of …

The Bactericidal Activity of Human Polymorphonuclear Leukocytes Before and After the Ingestion of Glucose
<p>The bactericidal test has been used to determine whether the consumption of concentrated carbohydrate affects the ability of human leukocytes to destroy bacteria. Subjects were given a dose of 100 grams of glucose. Two hours later a blood sample was drawn and incubated with Staphylococcus …

Strategies to potentiate bactericidal antimicrobial activity based on the suppression of bacterial stress response systems
… the SOS response has been shown to enhance the bactericidal activity of antimicrobials such as quinolones. Furthermore, bactericidal antimicrobials such as quinolones are also associated with the accumulation of reactive oxygen species (ROS) under aerobic conditions, inducing reactions that can …

The isolation and assessment of the antimicrobial activity of bacteriolytic and bactericidal endolysins of enterobacteriaceae infecting bacteriophages
Thesis submitted in fulfilment for the requirements of the degree of Master of Health Science in Medical Laboratory Science, Durban University of Technology, Durban, South Africa, 2025.

To devise a method of expressing the bactericidal efficiency of a disinfectant other than the standard F.D.A. phenol coefficienct method
Thesis (M.S.)--Michigan State College of Agriculture and Applied Science. Dept. of Bacteriology, 1940

Evaluation of the Photometric Assay Method to Quantitate the Bactericidal Action of Normal and Immune Rabbit Sera on SALMONELLA PULLORUM
<p>The bactericidal antibody test depends on the presence of sufficient complement, magnesium ions, and specific antibody to produce killing of certain gram negative bacilli. This study was undertaken to demonstrate whether or not Salmonella pullorum is an organism which is susceptible to this …

Physiological Factors Affecting the Bactericidal Activity of the Western Fence Lizard (Sceloporus occidentalis) for the Lyme Disease Spirochete, Borrelia burgdorferi
… was quantified. Adult lizards had higher bactericidal activity than first-year juveniles, suggesting that complement-mediated inactivation develops with maturity and/or exposure to spirochete antigens. Also, bactericidal activity was positively associated with lizard tick load and body …

Generation of SOS inhibitors as co-drugs to potentiate the activity of bactericidal antibiotics and to block the emergence of antibiotic resistance
… were found to potentiate the activity of bactericidal antibiotics and reduce the ability of bacteria to acquire antibiotic resistance mutations. This study highlights the ability of RecA inhibitors to potentiate the activity of antibiotics and provides a strategy for prolonging the life …

High throughput measurement of antibody and complement mediated immunity to meningococcal disease
… of protection for meningococcal disease is serum bactericidal activity. The importance of bactericidal activity was established by Goldschneider et al. (1969) who demonstrated an inverse relationship between disease incidence and bactericidal titres of ≥1:4. The importance of antibody and …

A molecular investigation of the antimicrobial functions of the human S100 host-defense proteins
… the second half of this thesis, we examine the bactericidal properties of the four S100 proteins. Our results agree with prior work on the bactericidal properties of S100A7. Furthermore, we show that CP and S100A15, but not S100A12, possess bactericidal activity at pH 5, and that CP is a …

Inactivation of foodborne pathogens by fruit wines
… produced from grapes have been found to possess bactericidal properties on a number of pathogens in vitro, suggesting possible health benefits that may be derived from microbiological safety. This study investigated the bactericidal effects in wines made from fruits other than grape. The …

In vivo display: a selection and its derivatives for antimicrobial peptide lead identification
… including bacteriolytic, bacteriostatic, bactericidal and growth rate reducing or weakly inhibitory. The cytoplasmic selection, in which the peptide library is fused to the C-terminus (cIVD) or the N-terminus (nIVD) of EmGFP produced 39 and 5 peptides, respectively. Of the 39 peptides …

Size Dependent Antimicrobial Properties of Sugar Encapsulated Gold Nanoparticles
… the dGNPs to be bacteriostatic as well as bactericidal. The dGNPs exhibited their bactericidal action through the disruption of the bacterial cell membrane causing leakage of cytoplasmic content. The overall outcomes of this study suggest that dGNPs hold promise as a potent antimicrobial …
