Detection of Chlamydia trachomatis inclusions in Mccoy cell cultures with fluorescein-conjugated monoclonal antibodies.

Stamm, W E, Tam, M, Koester, M, Cles, L

We compared two methods for identification of Chlamydia trachomatis inclusions in McCoy cell monolayers: conventional iodine staining and immunofluorescence staining with monoclonal antibodies...

Enzyme immunoassay for detection of antibody-coated bacteria.

Stamm, W E, Cutter, B E, Grootes-Reuvecamp, G A

To quantitatively evaluate factors potentially affecting antibody coating of bacteria in urine, we developed an assay with enzyme-linked rather than fluorescein-conjugated immunoglobulin. Using the...

Microtest procedure for isolation of Chlamydia trachomatis.

Yoder, B L, Stamm, W E, Koester, C M, Alexander, E R

Management of patients potentially infected with Chlamydia trachomatis has been hampered by the cost and time required to perform Chlamydia cultures. To isolate C. trachomatis, we developed a...

Nucleotide sequence of the variable domains within the major outer membrane protein gene from serovariants of Chlamydia trachomatis.

Lampe, M F, Suchland, R J, Stamm, W E

During studies in which we serotyped large numbers of Chlamydia trachomatis clinical isolates by using monoclonal antibodies, three novel serological variants (D-, D*, and I-) were identified. To...

Haemophilus ducreyi attaches to and invades human epithelial cells in vitro.

Totten, P A, Lara, J C, Norn, D V, Stamm, W E

Haemophilus ducreyi is a sexually transmitted pathogen that causes genital ulcers and inguinal adenopathy. Because chancroidal ulcers are most commonly located on the foreskins of uncircumcised...
