Brittle Weld Crack Starters in Drop Weight Tests, (1998)
A number of brittle weld bead crack starters have been examined and the shortcomings of each are discussed. The standard ASTM methods have been found to be unreliable. A crack starter developed at...
We used a double-label immunofluorescence assay to examine the ability of Chlamydia trachomatis serovar F to infect and develop within HeLa 229 cells previously infected with serovar E. No exclusion...
Distribution of an antigenically related iron-regulated protein among the Neisseria spp.
Mietzner, T A, Barnes, R C, JeanLouis, Y A, Shafer, W M, Morse, S A
Several iron-regulated proteins of Neisseria gonorrhoeae have been reported. One of these, a 37,000-molecular-weight protein (37K protein), appears to be common to all gonococcal isolates. Recently,...
Tubulin and high-molecular-weight polypeptides as Giardia lamblia antigens.
Torian, B E, Barnes, R C, Stephens, R S, Stibbs, H H
We determined the antigenic specificities of nine murine monoclonal antibodies to Giardia lamblia. Four distinct antibody reaction patterns were detected by immunofluorescence with G. lamblia...
Tilton, R C, Judson, F N, Barnes, R C, Gruninger, R P, Ryan, R W, Steingrimsson, O
Four hundred and seventy-three men and women at high risk for sexually transmitted disease were tested for the presence of Chlamydia trachomatis in the urethra or the endocervix. Four groups were...
Enzyme immunoassay to determine exposure to Chlamydia pneumoniae (strain TWAR).
Ladany, S, Black, C M, Farshy, C E, Ossewaarde, J M, Barnes, R C
Recent studies suggest that a group of Chlamydia strains known as TWAR, which are now proposed to be a new species called Chlamydia pneumoniae, may be a frequent cause of respiratory disease in the...
Quantitative culture of endocervical Chlamydia trachomatis.
Barnes, R C, Katz, B P, Rolfs, R T, Batteiger, B, Caine, V, Jones, R B
We examined the number of Chlamydia trachomatis inclusions produced in the initial passage of cell cultures of endocervical specimens from 1,231 women with positive chlamydial cultures who attended a...
Magder, L S, Klontz, K C, Bush, L H, Barnes, R C
We compared the performance of a commercial enzyme immunoassay (EIA) (Chlamydiazyme; Abbott Diagnostics, North Chicago, Ill.) with that of cell culture for the detection of Chlamydia trachomatis...
Barnes, R C, Wang, S P, Kuo, C C, Stamm, W E
The technical complexity of determining the serovar of Chlamydia trachomatis strains has limited the use of serotyping in clinical and epidemiologic studies. We developed a simple method for rapidly...
Laboratory diagnosis of human chlamydial infections.
Chlamydia trachomatis is a human pathogen that causes ocular disease (trachoma and inclusion conjunctivitis), genital disease (cervicitis, urethritis, salpingitis, and lymphogranuloma venereum), and...
Prevalence of antibody to LAV/HTLV-III among homosexual men in Seattle.
Collier, A C, Barnes, R C, Handsfield, H H
The prevalence of antibody to LAV/HTLV-III among homosexual men attending a community clinic and a sexually transmitted disease clinic in Seattle, Washington in early 1985 was 42 per cent and 32 per...
We used a double-label immunofluorescence assay to examine the ability of Chlamydia trachomatis serovar F to infect and develop within HeLa 229 cells previously infected with serovar E. No exclusion...

Seroepidemiology of chlamydia in Costa Rica.
Vetter, K M, Barnes, R C, Oberle, M W, Rosero-Bixby, L, Schachter, J
A population-based study of the sero-epidemiology of chlamydia was performed among a nationally representative sample of 760 Costa Rican women aged 25 to 59 years. Interviews and sera collection were...
