Psychiatric disorders such as schizophrenia are commonly accompanied by cognitive impairments that are treatment resistant and crucial to functional outcome. There has been great interest in studying cognitive measures as endophenotypes for psychiatric disorders, with the hope that their genetic basis will be clearer. To investigate this, we performed a(More)
AIMS To investigate the prevalence and virulence characteristics of Escherichia coli O157:H7 after a number of beef process operations at a commercial Irish abattoir. METHODS AND RESULTS Two 12-month studies were carried out. The first study (study 1) examined the prevalence of E. coli O157:H7 at up to six sites on carcasses at eight stages of the(More)
Thirty-six carcasses were sampled over a 12-month period at an Irish beef abattoir. Between one and five carcass sites (including the hock, brisket, cranial back, bung, inside round and outside round) were sampled after hind leg skinning, hide removal, bung tying, evisceration, splitting, washing, chilling for 24 h and boning, using a wet and dry, cotton(More)
It was recently suggested that the Kibra polymorphism rs17070145 has a strong effect on multiple episodic memory tasks in humans. We attempted to replicate this using two cohorts of European genetic origin (n = 319 and n = 365). We found no association with either the original SNP or a set of tagging SNPs in the Kibra gene with multiple verbal memory tasks,(More)
AIMS To determine the prevalence, serotype and antibiotic resistance profile of Salmonella isolates in cattle and on carcasses at a commercial Irish abattoir. METHODS AND RESULTS Faecal, rumen and carcass samples were collected from a beef abattoir over a 12-month period and examined for the presence of Salmonella spp. Isolates were serotyped, phage typed(More)
Cattle are known reservoirs and asymptomatic excretors of Cryptosporidium, a protozoan parasite that causes severe and protracted diarrhoea in people. The incidence of Cryptosporidium was investigated in 288 matched samples taken from beef carcases of 1 g samples of faeces retrieved immediately after de-legging, 25 cm2 samples of beef excised from the rump(More)
INTRODUCTION A highly polymorphic T homopolymer was recently found to be associated with late-onset Alzheimer's disease risk and age of onset. OBJECTIVE To explore the effects of the polymorphic polyT tract (rs10524523, referred as '523') on cognitive performance in cognitively healthy elderly individuals. METHODS One hundred eighty-one participants(More)
The prevalence of Cryptosporidium spp. in 50 l samples of water used to wash beef carcasses at (a) an abattoir with a borehole water (BH) supply (n = 46) and (b) an abattoir with a river water (RW) supply (n = 48) was determined. In addition, a 100 l water sample and post-wash carcass samples (n = 24) were collected from the RW supply on a single day in(More)
Cattle were visually inspected in the lairage of a commercial abattoir and assigned to a category ranging from 1 (very clean) to 5 (very dirty) depending on the observed cleanliness of the hide. Animals from categories 2, 3 and 5 were slaughtered and total viable counts (TVCs) enumerated at five sites (hock, brisket, cranial back, bung and inside round) on(More)
AIMS The aim of this research was to examine the effect of thermal treatments on the viability and infectivity of Cryptosporidium parvum oocysts attached to a beef surface. METHODS AND RESULTS This study examined the effects of heat treatment (60 or 75 degrees C) on the viability of C. parvum oocysts inoculated onto the surface of beef muscle estimated by(More)
