Bactericidal activity of topical antiseptics and their gargles against Bordetella pertussis.

Bordetella pertussis is the etiological agent of whooping cough, a common cause of respiratory illness in both children and adults. In the present study, we investigated the bactericidal activity of four antiseptics-povidone-iodine (PVP-I), benzethonium chloride (BEC), chlorhexidine gluconate (CHG) and benzalkonium chloride (BAC)-against B. pertussis ATCC9797 and clinical isolates.

Treatment of Pseudomonas aeruginosa biofilms with a combination of fluoroquinolones and fosfomycin in a rat urinary tract infection model.

Foreign body-associated infectious disease is currently one of the most problematic hospital-acquired infections. Patients with placement of urinary catheters are especially susceptible to such infection, that is biofilm infection. In this study, we focused on the therapeutic efficacy of prulifloxacin (PUFX) against Pseudomonas aeruginosa OP 14-210, isolated from a patient with complicated urinary tract infection.

In vitro activities of oral cephem and telithromycin against clinical isolates of major respiratory pathogens in Japan.

The in vitro antibacterial activities of oral cephem antibiotics and ketolide telithromycin against major respiratory pathogens possessing beta-lactam-resistant mutations (within the pbp gene) and/or macrolide-resistant genes (erm and mef) were examined in clinical isolates collected at 66 institutes in all over the Japan between 2002 and 2003. Telithromycin showed the strongest antibacterial activity against methicillinsusceptible Staphylococcus aureus strains with and without macrolide-resistant genes, such as ermA or ermC gene. All the cephem antibiotics showed potent antibacterial activity against Streptococcus pyogenes, with minimum inhibitory concentrations (MICs) of 0.

Synergistic effect of fosfomycin and fluoroquinolones against Pseudomonas aeruginosa growing in a biofilm.

Ulifloxacin is the active form of the prodrug prulifloxacin and shows a highly potent antipseudomonal activity. In this study, we examined the combined effect of fosfomycin and ulifloxacin against Pseudomonas aeruginosa (P. aeruginosa) growing in a biofilm using a modified Robbins device with artificial urine, and compared it to that of the combination of fosfomycin and ciprofloxacin or levofloxacin.

Cell profiles of bronchoalveolar lavage fluid as prognosticators of idiopathic pulmonary fibrosis/usual interstitial pneumonia among Japanese Patients.

Background: The role of bronchoalveolar lavage fluid (BALF) cell profiles in predicting the clinical outcome of idiopathic pulmonary fibrosis (IPF)/usual interstitial pneumonia (UIP) is still under discussion.

Objective: To determine whether BALF cell profiles affect the survival of patients with UIP diagnosed by surgical lung biopsy/autopsy at the early stage of IPF.

Methods: This hospital-based retrospective cohort study used 81 Japanese patients with histologically proven IPF/UIP who underwent BAL examination.
