rotavirus is the most important pathogen responsible for acute diarrhea in infants and young children. the incidence of rotavirus infection was studied in 156 children less than six years of age who were suffering from acute gastroenteritis, between february 22, 2006 and february 21, 2007 in mashhad. rotavirus antigen was detected by latex agglutination test (rotascreen) in 28.8% of the stool s...

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 (...

In order to demonstrate that cells of Candida spp. may show considerable nonspecific agglutination in latex agglutination tests, 150 clinical and reference isolates of 12 yeast species were systematically studied by applying various test parameters. In fact, 40 (26.7%) of these isolates revealed nonspecific results, significantly associated with the time allowed for agglutination.

Vaginal swabs from women who on clinical evidence were thought to have vaginal candidosis were examined for yeasts by conventional laboratory methods (microscopy and culture) and also assayed for Candida antigens using a rapid (3 min) slide latex particle agglutination tests. Results showed that a diagnosis of vaginal candidosis based on clinical criteria alone is unreliable: only half of the w...

A simple method for capsular serotype determination of Klebsiella is described, using staphylococci or latex particles coated by specific antibodies and the supernatant of a bacterial suspension in saline as antigen. These methods may be at least as reliable as other methods and easier to perform and less expensive than other methods.

OBJECTIVES To compare the performance of three diagnostic methods for Trichomonas vaginalis infection-latex agglutination, saline wet mount, and culture. METHODS Vaginal swabs from 3807 women attending antenatal clinics were tested for the presence of T vaginalis by latex agglutination. All positives and the following two negatives were tested by wet preparation and culture. RESULTS The pre...

A latex particle agglutination test previously shown to be suitable for the rapid identification of Escherichia coli strains of human origin producing heat-labile enterotoxin (R. A. Finkelstein and Z. Yang, J. Clin. Microbiol. 18:23-28) is equally applicable to strains of porcine origin.
