A survey of two acute district general hospitals (A and B) was undertaken to investigate the extent of methicillin-resistant Staphylococcus aureus (MRSA) contamination of ward-based computer terminals. Of 25 terminals examined, MRSA was identified in six (24%). Environmental contamination was of a low level. Five of the MRSA positive terminals were from… (More)
A steady rise in the number of isolations of Mycobacterium xenopi from patients in a general hospital led to an examination of water taps. Most patients had been accommodated in a group of wards which had a common water supply. This organism was recovered from 35 of 69 outlets, mostly from hot and mixer taps in those wards. Mycobacterium kansasii was also… (More)
An ELISA was developed to determine the reactivity of peroxidase labelled Protein A and a recombinant Protein A + Protein G construct, to sera from a variety of laboratory, domestic and wild animals from Africa. There was variability in the binding capacity of sera from individuals of the same species, but four groups could be recognized. Sera from birds… (More)
Two established immunodiagnostic techniques, immunofluorescence and indirect haemagglutination, were compared with ELISA (enzyme-linked immunosorbent assay) using intact promastigotes as antigen for the detection of specific antibodies against Leishmania in the serum of patients with visceral or mucosal leishmaniasis from the Sudan. The ELISA was found to… (More)
A skin test survey was conducted among 1035 children aged 7-19 years living in three cities in Vietnam. Fifteen new tuberculins, including leprosin-A, were applied; an induration of 2 mm diameter or more was considered positive. Compared to some other tropical countries, low levels of sensitisation were recorded and remarkable regional differences were… (More)
Living flies collected from three locations were cultured on selective medium for Campylobacter spp. Campylobacter jejuni was isolated from five (2.4%) of 210 flies examined. These results suggest that the potential hazard to health from the transmission of campylobacters from animals to human food by flies is small.
There have been considerable improvements in the collection of health-related quality of life (HRQOL) data in oncology over the past 20 years. The facility with which HRQOL information can now be collected from patients has also been associated with an improved understanding of the meaning of HRQOL and the association between HRQOL and patients' treatment… (More)
A 66-year-old man presented with arthritis of the right knee of 3 months' duration. Cytologic examination of synovial fluid (SF) showed numerous lipid laden macrophages. Radiographs and a nuclear scintigram established the presence of a fracture of the lateral tibial plateau. The diagnostic significance of lipid laden macrophages in SF is reviewed.
Infections with Leishmania parasites are initiated by bites from infected sandflies; the injected promastigotes are attacked by phagocytic cells but succeed in entering cells of the macrophage family and surviving in them. The secrets of the success of the extracellular form in penetrating the host cell and of the intracellular form in surviving in a… (More)
