Identification of causative pathogens in eyes with bacterial conjunctivitis by bacterial cell count and microbiota analysis.

Purpose: To determine the causative pathogens in eyes with bacterial conjunctivitis.

Design: Evaluation of diagnostic test or technology.

Participants: Thirteen eyes diagnosed clinically with bacterial conjunctivitis and 12 eyes with normal conjunctival sac were studied.

Bacterial hazards of sludge brought ashore by the tsunami after the great East Japan earthquake of 2011.

Objectives: The aim of this study was to identify bacteria in sludge brought by the 2011 tsunami in Japan to determine the necessary precautions for workers who handle the sludge.

Methods: Two sludge samples and one water sample were collected from each of two sites in Miyagi Prefecture in June 2011. We also obtained control samples from a paddy field and a dry beach in Fukuoka, Japan.

Synergism of Staphylococcus aureus colonization and allergic reaction in the nasal cavity in mice.

Background: The aim of this study is to investigate the reciprocal effect of Staphylococcus aureus colonization and allergic rhinitis in an allergy model of mice.

Methods: BALB/c mice with intraperitoneal ovalbumin (OVA) sensitization and/or intranasal S. aureus inoculation were prepared.

Small and rough colony pseudomonas aeruginosa with elevated biofilm formation ability isolated in hospitalized patients.

Pseudomonas aeruginosa is a key pathogen of nosocomial infection, and causes persistent infection in patients with specific diseases like cystic fibrosis (CF). It has been reported that patients affected with CF discharge, at a high frequency, small colony variants with high adherence ability. In routine laboratory testing, we found atypical small and rough type (SR) colony variants of P.

[A bacteriological study of multiple-drug-resistant Pseudomonas aeruginosa isolates derived from 2 patients].

We investigated the isolation circumstances of multiple-drug-resistant Pseudomonas aeruginosa (MDRP) in the UOEH hospital and the bacterial analysis of isolated MDRP. From January to October 2003, MDRP was isolated from 2 patients. During this period, the isolation frequency of MDRP was 0.

[Control measures against Serratia marcescens colonization at the neonatal intensive care unit of UOEH hospital].

In September 2001, twelve neonatal intensive care unit (NICU) patients were found to be colonized with pigment-producing strains of Serratia marcescens. The UOEH Infection Control Group (ICG) committee investigated the source of this epidemic and carried out several remedial measures. Immediate investigation of both the environment and the hands of health care workers were enforced.
