J Infect Dis . 1998 Nov; 178(6):1707-12. PMID: 9815223
Transmission of Chlamydia trachomatis and Neisseria gonorrhoeae among infected men and their female sex partners was examined using a design enhancing the likelihood that spread was directed from men to...

Sex Transm Dis . 1994 Nov; 21(6):332-7. PMID: 7871447
Background And Objectives: Gonococcal infections caused by penicillinase-producing Neisseria gonorrhoeae (PPNG) isolates have increased in geographic distribution and prevalence. It was postulated that PPNG strains would become endemic in Honolulu...

J Infect Dis . 1993 May; 167(5):1106-11. PMID: 8098052
Restriction fragment length polymorphism (RFLP) and plasmid analyses were used to evaluate an outbreak of Haemophilus ducreyi in San Francisco. Fifty-four cases of culture-confirmed chancroid occurred between May 1989 and...

Motley M, Sarafian S, Knapp J, Zaidi A, Schmid G
Antimicrob Agents Chemother . 1992 Aug; 36(8):1639-43. PMID: 1416845
We determined the susceptibilities of 94 strains of Haemophilus ducreyi isolated in various municipalities in the United States between 1982 and 1989 to the following antimicrobial agents: amoxicillin-clavulanic acid, ceftriaxone,...

Sarafian S, Knapp J
Sex Transm Dis . 1992 Jan; 19(1):35-8. PMID: 1561586
To determine the distribution and extent of temporal changes in Haemophilus ducreyi strains in the United States, 342 isolates of H. ducreyi collected in 18 urban areas in the United...

Sarafian S, Johnson S, Thomas M, Knapp J
J Clin Microbiol . 1991 Oct; 29(10):2333-4. PMID: 1939592
Thirty isolates of Haemophilus ducreyi collected in Thailand in 1984 were characterized by plasmid content. Three novel plasmids with estimated molecular masses of 1.8, 2.6, and 2.8 MDa were observed...

Sex Transm Dis . 1991 Oct; 18(4):201-4. PMID: 1771472
One hundred and fifty-two beta-lactamase-producing Neisseria gonorrhoeae isolates from Japan (n = 25; 1983, 1985, 1986), Taiwan (n = 14; 1983, 1984), and the Republics of Singapore (n = 58;...

J Clin Microbiol . 1991 Sep; 29(9):1949-54. PMID: 1663518
Intraspecies genotypic heterogeneity among Haemophilus ducreyi isolates was examined by using genomic fingerprints with rRNA from Escherichia coli as a probe. DNA from 44 isolates of H. ducreyi was digested...

J Clin Microbiol . 1991 Jan; 29(1):70-5. PMID: 1704384
An agglutination assay was used to examine the binding of purified human S protein (vitronectin, serum spreading factor) to 201 clinical isolates of Neisseria gonorrhoeae. Strains belonging to the protein...

Sex Transm Dis . 1990 Apr; 17(2):67-71. PMID: 2113718
beta-lactamase plasmids confer high-level penicillin resistance on strains of Neisseria gonorrhoeae and may be mobilized between strains by conjugative plasmids. The authors examined 32 isolates belonging to 23 auxotype/serovar (A/S)...
