Program logic of a service collaboration to support parents with intellectual disability.

Background: This article describes the Steps to Confident Parenting (SCP) program, developed by an Australian family service consortium. The SCP integrates home-based and case-management services to enhance the skills of parents with a diagnosed or suspected intellectual disability/cognitive impairment and to prevent child protection interventions.

Method: 'Program explication' methodology documented the components/activities, and underpinning evidence for this practitioner designed service through interviews with nine agency staff.

Characteristics of gram-negative urinary tract infections caused by extended spectrum beta lactamases: pivmecillinam as a treatment option within South Dublin, Ireland.

Background: The prevalence of urinary tract infections (UTIs) caused by extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae is increasing and the therapeutic options are limited, especially in primary care. Recent indications have suggested pivmecillinam to be a suitable option. This pilot study aimed to assess the viability of pivmecillinam as a therapeutic option in a Dublin cohort of mixed community and healthcare origin.

CapE (capture, amplify, extract): A rapid method for detection of low level contamination of water with Verocytotoxigenic Escherichia coli (VTEC).

Verocytotoxigenic Escherichia coli (VTEC) is associated with a wide spectrum of disease from mild self-limiting diarrhoea to haemolytic uremic syndrome. Contaminated drinking water is accepted as an important route of transmission in Ireland as elsewhere however established methods for detection of VTEC in drinking water have limitations. We describe a sensitive and rapid method for detection of VTEC from large volumes (20 to 30L) of drinking water based on filtration, enrichment culture of filters and real-time PCR detection of VTEC virulence and O antigen determinants from enrichments.

Real-time PCR detection of Dinophysis species in Irish coastal waters.

Diarrhetic shellfish toxin-producing Dinophysis species occur in Irish coastal waters throughout the year. Dinophysis acuta and Dinophysis acuminata are the most commonly occurring species and are responsible for the majority of closures of Irish mussel farms. This study describes the development of a qualitative real-time polymerase chain reaction (PCR) assay for identification of D.

DNA extraction method affects microbial community profiles from soils and sediment.

To evaluate whether different deoxyribonucleic acid (DNA) extraction procedures can affect estimates of bacterial community composition, based on the 16S ribosomal ribonucleic acid gene denaturing gradient gel electrophoresis (DGGE) profiles, we compared four in situ lysis procedures using three soils and one marine sediment. Analysis of DGGE profiles, generated by polymerase chain reaction of purified DNA extracts, demonstrated that the choice of DNA extraction method significantly influenced the bacterial community profiles generated. This was reflected both in the number of bands or ribotypes detected from each sample and in subsequent principle coordinate analysis and unweighted-pair group method using arithmetic average analyses.

Accessing the black box of microbial diversity and ecophysiology: recent advances through polyphasic experiments.

The microbial ecology of a range of anaerobic biological assemblages (granular sludge) from full- and laboratory-scale wastewater treatment bioreactors, and of crop-growing and peat soils, was determined using a variety of 16S rRNA gene-based techniques, including clone library, terminal restriction fragment length polymorphism (TRFLP) and denaturing gradient gel electrophoresis (DGGE) analyses. Fluorescent in situ hybridization (FISH) using 16S rRNA gene-targeted probes was employed to complete a "full-cycle rRNA approach" with selected biomass. Genetic fingerprinting (TRFLP and DGGE) was effectively used to elucidate community structure-crop relationships, and to detect and monitor trends in bioreactor sludge and specific enrichment cultures of peat soil.
