AIMS To assess the value of a new rapid fluorescence method for the diagnosis of microsporidiosis in HIV seropositive patients. METHODS Microsporidian spores in stools were demonstrated by using the fluorochrome stain Uvitex 2B. The new technique was evaluated in three groups of HIV seropositive patients with diarrhoea. Group 1: 19 patients with biopsy confirmed E bieneusi infection (186 stoo...
Tick-transmitted diseases are an emerging health problem, and the hard tick Ixodes ricinus is the main vector for Borrelia spp., tick-borne encephalitis virus and most of the spotted fever Rickettsiae in Europe. The aim of the present study was to examine the incidence of rickettsial infection in the southernmost and south central parts of Sweden and the Åland Islands in Finland, the risk of in...
total igm, iga, and igm-rheumatoid factor (rf) and iga-rf were quantitated in the serum and synovial fluid of 35 seropositive and 8 seronegative rheumatoid arthritis (ra) patients, using a sensitive enzyme-linked immunosorbent assay (elisa). mononuclear cells isolated from peripheral blood and synovial fluid of three seropositive patients were also stimulated in vitro with phorbol myristate ace...
Results from a representative survey of respondents in Florida are given, concerning their knowledge about members of their personal network, and specifically how many people respondents know in selected subpopulations. We employ a method known as a "network scale-up method". By using a collection of subpopulations of known size, and also asking about one subpopulation (those who are seropositi...
Scrub and murine typhus infections are under-diagnosed causes of febrile illness across the tropics, and it is not known how common they are in Bangladesh. We conducted a prospective seroepidemiologic survey across six major teaching hospitals in Bangladesh by using an IgM enzyme-linked immunosorbent assay. Results indicated recent exposure (287 of 1,209, 23.7% seropositive for Orientia tsutsug...
We tested for negative effects of West Nile virus (WNV) on a breeding population of eastern bluebirds in Alabama by comparing fecundity and reproductive success in years before and after the arrival of WNV and by comparing fecundity, reproductive success, and overwinter survival of seropositive and seronegative individuals within the same population in the same years. We found that female blueb...
OBJECTIVE To assess the effect of bacterial vaginosis (BV) on the risk of high-grade squamous intraepithelial lesions (HSIL) among HIV-seropositive women. METHODS A hospital-based prospective cohort study of HIV-seropositive women was conducted in Johannesburg, South Africa from January 2005 to September 2009. Multivariate log-binomial and Poisson regressions were used to estimate prevalence ...
Neuropsychological impairments punctuate the early neurological involvement among HIV-1 infected patients. Three groups of patients, twenty in each were selected. The first group consisted of seronegative local controls, the second being a group of asymptomatic seropositive patients and the third a group of seropositive symptomatic individuals. All these three groups were tested using standard ...
