An alternative method for detecting the production of slime by coagulase negative staphylococci was compared with the routinely used Christensen method on 124 isolates of coagulase negative staphylococci from carriage sites, blood cultures, and infected peritoneal dialysis fluids. The alternative method requires the use of a specially prepared solid(More)
Methicillin-resistant Staphylococcus aureus (MRSA) isolates recovered in Irish hospitals between 1971 and 2002 were characterized using multilocus sequence typing (MLST) (n = 130) and SCCmec typing (n = 172). Where atypical SCCmec typing results were obtained, PCR amplification of entire SCCmec elements, analysis of amplimer mobility, and nucleotide(More)
Among 137 members of 30 families, 6% (and 8% of those aged under 15 years) were seropositive for toxocara antibodies. In these seropositive subjects and in 84 patients known to have raised toxocara titres the commonest clinical features were abdominal pain, hepatomegaly, anorexia, nausea, vomiting, lethargy, sleep and behaviour disturbances, pneumonia,(More)
The Fc gammaR receptors for IgG, Fc gammaRI, Fc gammaRII and Fc gammaRIII were measured on neutrophils and monocytes from 36 patients suspected of systemic infection. These results were compared with 30 blood donor controls to assess the level of expression as an early indicator of bacterial infection. Fc gammaRI expression on neutrophils was found to be(More)
The efficacy of inhaled amphotericin B in prevention of invasive aspergillosis in patients with granulocytopenia (granulocytes less than 0.5 X 10(9)/l for greater than 10 days) was investigated over a 12-month period. Amphotericin B prophylaxis was administered twice daily for the period of granulocytopenia to 34 patients who were at risk during 144(More)
In order to evaluate the diagnostic usefulness of Gram-staining films from petechial lesions in suspected meningococcal infection, data from 52 patients with confirmed infection were reviewed. Gram-negative diplococci were found in specimens from skin films in 80% (24/30) patients with petechiae. This is significantly better than results reported for(More)
Between Dec. 1992 and Aug. 1993, the MRSA population in the Federated Dublin Voluntary Hospitals and St James's Hospital group was studied with an antibiogram-resistogram (AR) typing scheme in which AR patterns were determined by testing susceptibility to 22 antibiotics and chemicals by a modified Stokes' disk diffusion technique. The typing scheme divided(More)
Between 1989 and 1998, the number of patients carrying methicillin-resistant Staphylococcus aureus in one Dublin hospital increased fourfold, and the antibiogram-resistogram (AR) type distribution changed. In 1989, the predominant AR types were AR01 and AR02; in 1993, AR14 predominated; and in 1994, AR14 and AR13 were predominant. By 1998, the prevalence of(More)
Risk factors predictive of methicillin-resistant Staphylococcus aureus (MRSA) colonization in 786 of 910 nursing home residents were evaluated. A customized questionnaire was completed by theresidents, who were screened for MRSA. The risk factors significantly associated with MRSA colonization were male sex, age >80 years, residence in the nursing home for(More)
