Antibacterial action of spermine: effect on urinary tract pathogens.
The basic polyamine spermine was tested for antibacterial activity at two pH levels by the modified cup method against a variety of gram-positive and gram-negative organisms isolated from urine. At pH 6.4, with concentrations ranging from 39 to 2,500 mug per 0.1 ml, there were no clear zones of inhibition seen with any of the gram-negative test organisms, although some adverse effect on growth ...
متن کاملLethal Action of Potassium Permanganate on Vibrios
Potassium permanganate pills were used by Rogers (1913) in cholera cases to neutralize the toxins of the cholera vibrio, and 'permanganate is commonly used to disinfect clothes, well water and tank water, cholera stools, etc., during an epidemic. Hands also are often washed with permanganate solutions after attending cholera cases. There are various old references to potassium permanganate in d...
متن کاملLethal action of ribonuclease for thermophilic bacilli.
Thompson, T. L. (University of Nebraska, Lincoln), and J. M. Shively. Lethal action of ribonuclease for thermophilic bacilli. J. Bacteriol 91:673-676. 1966.-Exposure of a thermophilic bacillus, NU 47, to 0.2 mug/ml of pancreatic ribonuclease resulted in a drastic reduction of viable cells. The observed lethality is thought to be associated specifically with the ribonuclease, since heat treatmen...
متن کاملSpermine protects mice against lethal sepsis partly by attenuating surrogate inflammatory markers.
The pathogenesis of sepsis is partly attributable to dysregulated inflammatory response mediated by pathogen-associated molecular patterns (PAMPs) (for example, endotoxin) and damage-associated molecular patterns (DAMPs) (for example, high-mobility group box 1 [HMGB1]). An endogenous ubiquitous polyamine, spermine, inhibits endotoxin-induced cytokine release in vitro, but its capacities to atte...
متن کاملDoes toxic defence in Nycticebus spp. relate to ectoparasites? The lethal effects of slow loris venom on arthropods.
The venom produced by slow lorises (Nycticebus spp.) is toxic both intra- and inter-specifically. In this study we assessed the ecoparasite repellent properties of their venom. We tested venom from two Indonesian slow loris species: Nycticebus javanicus and Nycticebus coucang. Arthropods directly exposed to brachial gland secretions mixed with saliva from both species were immediately impaired ...
