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 herbal extracts

International Journal of Hygiene and Environmental Health, 2003
The antimicrobial activity of total herbal extracts has been investigated. The MIC of extracts of Evodia rutaecarpa and grape kernel ranged between 0.25 and 1 mg/ml against gram-positive cocci and P. aeruginosa. Cocci were killed after 30-90 min of incubation in grape kernel extract (0.5-1.5 mg/ml), and after 8 h in evodia extract (0.5-1 mg/ml ...

Bactericidal Activity of Wet Cerumen

Annals of Otology, Rhinology & Laryngology, 1984
The viable populations of seven species of bacteria were reduced 17% to 99% by treatment with a 3% suspension of human cerumen of the soft or “wet” type. Species tested for susceptibility to cerumen were Staphylococcus aureus, Staphylococcus epidermidis.

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

Analysis of Neutrophil Bactericidal Activity

2007
The primary function of neutrophils is to engulf and destroy invading pathogens. If the bactericidal capacity of neutrophils is defective, an individual may suffer from enhanced susceptibility to potentially fatal microbial infection. To identify such defects, and to investigate the mechanisms used to kill bacteria, the bactericidal activity of ...

Bactericidal activity of disinfectants

Glavnyj zootehnik (Head of Animal Breeding), 2020
The modern market of drugs off ers a wide range of disinfectants. However, the constant use of the same drugs contributes to the development of resistance in the microfl ora and reduces the quality of activities. In this regard to develop eff ective measures to combat and prevent infectious diseases, it is necessary to periodically monitor the activity

Measuring Neutrophil Bactericidal Activity

2018
The best-known role of neutrophils is control of pathogen growth. Neutrophils contain and kill pathogens through a variety of antimicrobial activities. Regardless of the mechanism, the ability to kill pathogens is a vital outcome. This chapter describes a method to measure the in vitro bactericidal activity of isolated neutrophils as the endpoint of ...

Bactericidal Activity of Tinidazole

Chemotherapy, 1977
The new antiprotozoal agent, tinidazole, was found to be bactericidal against all 52 isolates of obligate anaerobic bacteria tested, 42 Bacteroides fragilis, 4 clostridia and 6 ...

Photoinduced bactericidal activity of TiO2 films

Applied Biochemistry and Microbiology, 2011
A decline in CFU of gram-positive and gram-negative bacteria on the surface of UV illuminated TiO2 films (wavelength of 380 nm) is shown. A 29, 45, and 47% decrease in bacterial viability of Staphylococcus aureus, Staphylococcus epidermidis, and Escherichia coli, respectively, was seen following a 12-min exposition.

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.
