A four-year prospective study was carried out to determine the incidence and rate of development of resistance by common urinary tract infection (UTI) pathogens to quinolone antimicrobial agents. Results show that there is high intrinsic resistance to the quinolones among strains of Pseudomonas aeruginosa (43.4%), Escherichia coli (26.3%), and Proteus spp. (17.1%). Over four years, rising rates...

We evaluated the in vitro antibiotic susceptibilities of 31 coagulase-negative Staphylococcus isolates causing septicemia in neutropenic patients undergoing norfloxacin prophylaxis. All the strains but one were resistant to 1 microgram of norfloxacin per ml. At the same concentration, ciprofloxacin, ofloxacin, imipenem, and pefloxacin were inhibitory for 19 (61%), 19 (61%), 18 (58%), and 14 (45...

A group of selected enzymes were subjected to continuous pulsed electric field (PEF) treatments to evaluate the inactivation effect of PEF. For a treatment time of 126 s, 51.7% and 83.8% of pepsin was inactivated at 37.0 kV/cm and 41.8 kV/cm, respectively. Enzyme activity of polyphenol oxidase decreased 38.2% when treated at 33.6 kV/cm for 126 s. Enzyme activity decreased 18.1% and 4.0% for per...

BACKGROUND AND OBJECTIVES Pulsed electric field (PEF) is a novel emerging technology which is believed to have the potential to substitute conventional thermal pasteurization (HTST). In the current study PEF was compared with HTST based on microbial inactivation and quality attributes. MATERIALS AND METHODS Juice was prepared by extracting it from Semirum apples. They were chilled to 4°C over...

The identification, prevention, and prompt treatment of exacerbations are major objectives of asthma management. We looked at change in PEF, symptoms, and use of rescue agonists during the 425 severe exacerbations that occurred during a 12-month parallel group study (FACET) in which low and high doses of budesonide with and without formoterol were compared in patients with asthma. Oral corticos...
