Risk factors of fecal colonization with extended-spectrum β-lactamase-producing in special nursing homes in Japan.

Objective: Japanese welfare facilities for the elderly are called as special nursing home (SNH), providing conventional-type with group care or unit-type with individual care. We investigated the risk factors of fecal colonization with extended-spectrum β-lactamase-producing (ESBL-E) of elderly who required care at SNH in Japan.

Methods: The feces discharged on diaper were obtained from the total of 100 residents with fecal incontinence in 9 SNHs located in Tokyo, Japan.

A survey on bacterial contamination of lavage water in electric warm-water lavage toilet seats and of the gluteal cleft after lavage.

Electric warm-water lavage toilet seats are in wide use as an appliance beneficial for the maintenance of hygiene and the prophylaxis and improvement of conditions such as constipation and hemorrhoids. In this study, we surveyed the bacterial content in the lavage water of warm-water lavage toilet seats, and fecal bacterial contamination of the gluteal and genital regions due to droplet infection from post-defecation lavage, to examine the problems inherent to the use of such lavage units. The presence of viable bacteria in lavage water was confirmed in this survey.

Molecular epidemiological analysis of methicillin-resistant staphylococci in a neonatal intensive care unit.

To investigate the contamination by and transmission of MRSA/MRCNS in the old NICU of Hospital A and the relocated NICU (new NICU), we isolated and evaluated staphylococci from nurses' palms, towels under the heads of neonates, infant incubators (including portholes and infant covers), and room air. Detection rates of MRSA/MRCNS isolated from different sample locations were 52.6% in the old NICU and 53.
