OBJECTIVE To elucidate the factors leading to catheter loss from recurrent infection in patients on continuous ambulatory peritoneal dialysis (CAPD). DESIGN All catheters removed from patients were prospectively examined for infection. SETTING CAPD unit in large tertiary-care general hospital. PATIENTS Sixty-five consecutive patients undergoing(More)
Sixty-six stool specimens from infants with diarrhoea in Nigeria were examined for the presence of viral pathogens. Rotaviruses were found in 25.8% of specimens and astroviruses in 1.5%. Serotypes were determined for 47.1% of the rotavirus positive specimens, all of which were serotype 1. RNA analysis revealed no unusual electrophoretic profiles. No enteric(More)
Spirochetes resembling Brachyspira aalborgi were found in the feces and rectal biopsies of a patient with persistent diarrhea. Although the organism failed to grow on bacteriologic media, it was found attached to the surfaces of the epithelial cells on the rectal lumen. Blunting and destruction of the cellular microvilli was evident. These induced(More)
The action of ciprofloxacin and norfloxacin on two strains of Escherichia coli was studied by diverse methods including electronmicroscopy, viable counting and continuous turbidimetric monitoring. During the first few hours of exposure to inhibitory concentrations of the drugs, the opacity of bacterial cultures continued to increase for a period that was(More)
The novel lipopeptide antibiotic, daptomycin, at a concentration of 8 mg/L, caused gross morphological changes in both a methicillin-sensitive and a methicillin-resistant strain of Staphylococcus aureus and in a strain of Enterococcus faecalis. The earliest (after 1 h) surface lesion observed was the appearance of boss-like processes randomly distributed on(More)
The author's autoethnographic article was accepted for publication and then blocked by her Institutional Review Board (IRB). The overt reasons for the " denial of approval " differ from accounts given behind closed doors. By weaving experience, excerpts from her article, and the responses of others into a narrative , the author creates an ongoing(More)
An accurate reflection of the pathogenicity of microorganisms and the therapeutic effects of antimicrobial agents on their growth necessitates testing within an in vivo environment. We have developed a novel diffusion chamber, incorporating two 0.22 microns membrane filters, for the growth of in vivo organisms. The chamber, which is implanted(More)
