BACKGROUND Lactic acid production is considered to be the major protection mechanism of lactobacilli against vaginal infections due to genital pathogens. Some species of Lactobacillus are also hydrogen peroxide (H(2)O(2)) producers. Nonoxynol-9 (N-9) is a nonionic detergent and is the active component of many spermicidal preparations. It immobilizes sperm(More)
The vagina has been increasingly viewed as an "ecosystem" whose normal microflora help protect it from invading pathogens, including those that cause urinary tract infections and sexually transmitted diseases. We tested new strains of lactobacilli as potential probiotics for maintenance of urogenital tract health, as well as prevention and therapy of(More)
Lactobacillus fermentum strain L23 produced a small bacteriocin, designated bacteriocin L23, with an estimated molecular mass of < 7000 Da. Isolation, purification, and partial characterization of bacteriocin L23 are described. It displayed a wide inhibitory spectrum including both Gram-negative and Gram-positive pathogenic strains and two species of(More)
This work deals with the design of multimode/multifrequency airborne radar suitable for imaging and subsurface sounding. The system operates at relatively low frequencies in the band ranging from VHF to UHF. It is able to work in two different modalities: (i) nadir-looking sounder in the VHF band (163 MHz) and (ii) side-looking imager (SAR) in the UHF band(More)
