One hundred sera from 49 patients with glandular toxoplasmosis were examined by a latex agglutination test, the dye test, an indirect haemagglutination test, and a double antibody sandwich enzyme linked immunosorbent assay (ELISA) for antitoxoplasma IgM. The results support previous findings that the dye test, indirect haemagglutination test, and latex agglutination test measure different antib...

Measurement of von Willebrand factor antigen (VWF : Ag) levels is usually performed in a specialised laboratory which limits its application in routine clinical practice. So far, no commercial rapid test kit is available for VWF : Ag estimation. This paper discusses the technical aspect of latex agglutination method which was established to suit the purpose of estimating von Willebrand factor (...

Latex agglutination assays utilizing polyclonal antibodies were developed for the top six non-O157 Shiga toxin-producing Escherichia coli (STEC) serogroups. Rabbit antisera were affinity purified through protein A/G columns, and the isolated immunoglobulins (IgGs) were covalently immobilized onto polystyrene latex particles. The resulting latex-IgG complex had a protein (IgG) load of 0.20 to 0...

Trichomoniasis is a worldwide infection and due to its complications rapid and accurate diagnosis of infection especially in pregnant women is very important. In this study, development of a latex agglutination test using native antigens for rapid diagnosis of trichomoniasis is investigated. Trichomonas vaginalis was harvested from TYIS33 culture medium and anti Trichomonas vaginalis antiserum ...

Cross-reactivity between Legionella spp. and Capnocytophaga ochracea was noted by latex agglutination tests (Serobact Legionella; Disposable Products, Adelaide, Australia). Four of 11 (36%) C. ochracea isolates agglutinated with latex reagents designed to identify Legionella pneumophila serogroups. C. ochracea isolated on buffered charcoal yeast extract media may give false-positive results in ...

in this study which has been carried out from 1996 until 1997 soluble latex agglutination antigen was prepared from L, donovani,sudan(s-1) by culturing in special media,harvesting,and later solubilizing by freezing and thawing.the antigen were futher prepared by high speed centrifugation.after measurement of the protein (lowry method) concentration of the antigen was set at 2.2 mg/ml,the antige...

Background: Rotavirus is a major cause of morbidity and mortality among children with gastroenteritis. Since the discovery of rotaviruses, several techniques have been used for their laboratory diagnosis; those included Electron Microscopy (EM) and enzyme immunoassay. These methods, however, are expensive and not readily available everywhere. We have developed a technique which can be used for ...

A new slide latex agglutination test was compared with microscopy and culture for diagnosing vaginal candidosis in 367 women attending a genitourinary medicine clinic. Vaginal candidosis occurred in 10% of the patients, and 7% had commensal carriage of Candida spp. The slide latex agglutination test was superior to microscopy in immediate diagnosis and was rapid and simple to perform. Of the pa...

A resurgence of interest in Toxoplasma gondii has occurred because this coccidian parasite causes lethal infections in immunologically compromised hosts and is responsible for at least 3,000 congenitally infected infants in the United States annually. Thus, rapid, specific, and inexpensive serologic tests are required for routine screening of patients, especially pregnant women. We have develop...
