The bactericidal activity of sparfloxacin

Journal of Antimicrobial Chemotherapy, 1992
Sparfloxacin was found to display a biphasic response against Escherichia coli, Staphylococcus aureus and Staphylococcus epidermidis in nutrient broth. Its optimum bactericidal concentration was found to be identical for all three species which contrasts with other clinically available fluoroquinolones that are more active against E.

Bactericidal activity of peroxynitrite

Archives of Biochemistry and Biophysics, 1992
Peroxynitrite is a strong oxidant formed by macrophages and potentially by other cells that produce nitric oxide and superoxide. Peroxynitrite was highly bactericidal, killing Escherichia coli in direct proportion to its concentration with an LD50 of 250 microM at 37 degrees C in potassium phosphate, pH 7.4.

Bactericidal activity of tuftsin

Molecular and Cellular Biochemistry, 1981
The biological activities of the phagocytosis stimulating tetrapeptide, Thr-Lys-Pro-Arg are discussed. A brief account on the stimulation by tuftsin of phagocytosis of various particles, including bacteria was reported. Stimulation of bactericidal activity by this tetrapeptide was investigated in vitro as well as in vivo.

Anomalous Serum Bactericidal Activity

American Journal of Clinical Pathology, 1973
The in vitro assay of serum bactericidal activity in several recent patients with severe infection has shown an unexpected prozone effect. That is, the undiluted, or minimally diluted serum from a patient receiving antibiotic therapy with cephalothin showed growth of a microbial inoculum, whereas more dilute specimens inhibited growth.

Bactericidal activity of disinfectants on listeria

Journal of Applied Bacteriology, 1993
A. VAN DE WEYER, M.‐J. DEVLEESCHOUWER AND J. DONY. 1993. The bactericidal activity on Listeria spp. of nine disinfectants used in the food industry was studied by previously published methods. The disinfectants were diluted to the test concentation in sterile standard hard water.

Analysis of Neutrophil Bactericidal Activity

2014
This chapter describes two methods for measuring the bactericidal activity of neutrophils. These are a new simple fluorescence-based assay, which quantifies bactericidal activity by measuring changes in bacterial fluorescence associated with a loss of membrane potential over time, and a more traditional colony counting protocol. Two variations of these

A bactericidal activity of microsomal preparations

Mutation Research/Genetic Toxicology, 1980
Exposure of suspension of Salmonella typhimurium tester strains TA1535, TA1537 and TA98 to mouse hepatic post-mitochondrial supernatants (S9) resulted in appreciable loss of bacterial viability. This lethal activity was destroyed by heating at 56 degrees C for 30 min. The toxic component of the S9 has not been identified.
