Specimens of cerebrospinal fluid from 201 patients with meningitis caused by Neisseria meningitidis groups A/B/C/135, Streptococcus pneumoniae (23 types), and Haemophilus influenzae type b were tested for the presence of specific bacterial antigens by latex agglutination, counterimmunoelectrophoresis (CIE), and protein A co-agglutination. Specific antigens were found in 75% of the specimens by ...

The group A rotavirus staphylococcal co-agglutination test was evaluated and its sensitivity and specificity compared with an in-house enzyme-linked immunosorbent assay (ELISA) and a commercial latex agglutination test (Rotalex). In addition, the storage stability of the staphylococcal reagents was ascertained. Examination of 136 clarified suspensions of diarrhoeal faeces by the staphylococcal ...

The diagnosis of visceral leishmaniasis involves isolation of the parasites in culture or invasive and risky techniques including demonstration of parasite in stained preparations of relevant tissues such as spleen, bone marrow or lymph node by light microscopic examination remains a gold standard. Serological tests using rK39 in ELISA or rapid immunochromatographic tests, direct agglutination ...

Introduction: The precise mechanism for antisperm antibody (ASA) mediated fertility impairment is unclear. In the male reproductive tract, ASA may have an adverse impact on sperm maturation and function or overall semen quality. In this study, the percentage of ASA-IgA was determined by the direct Mixed Agglutination Reaction (MAR) test in men from infertile couples in Khorramabad city. Further...

Methods Twenty hospitals (Hospitals A to T) throughout Taiwan (8 in northern, 2 in central, 7 in southern, 2 in eastern Taiwan, and one in rural island) were cultured for Legionella. We followed the standardized protocol to perform environmental cultures using (1) water samples; (2) BCYE and DGVP culture media; (3) latex agglutination test (LAX) and direct fluorescent antibody (DFA) technique f...

The spontaneous appearance of a second paratyphoid infection in a guinea pig population during the endemic stage of an earlier epidemic is reported. A comparative study of the gross pathology of the two infections indicated a difference in the loci of development of the respective organisms in the animal host. The two types were readily differentiated by direct agglutination with specific immun...

A quantitative particle agglutination assay using mobile holographic imaging and deep learning is demonstrated for point-of-care testing.
