Host cell infection by sexually transmitted disease (STD)-causing microbes and fertilization by spermatozoa may have some mechanisms in common. If so, certain noncytotoxic agents could inhibit the functional activity of both organisms. High molecular mass poly(sodium 4-styrenesulfonate) (T-PSS) may be one of these compounds. T-PSS alone (1 mg/ml) or in a(More)
Galectins are a family of beta-galactoside binding proteins that have been proposed as host receptors for bacteria because beta-galactoside carbohydrates are common in bacterial membrane glycolipid lipooligosaccharides (LOS) and lipopolysaccharides. We investigated the interaction of galectin-3 with gonococcal LOS that make lactosyl (Lc2 or Lac),(More)
OBJECTIVE To assess the contraceptive properties, antimicrobial activity, and safety of mandelic acid condensation polymer (SAMMA). DESIGN Experimental study of SAMMA's in vitro and in vivo properties. SETTING Academic research laboratories. PATIENT(S) Healthy volunteers for semen donation in an academic research environment. INTERVENTION(S)(More)
The spread of sexually transmitted infections (STIs) and limited methods for control of pregnancies presents high risks to the reproductive health of women. Methods controlled by women and directed toward disease prevention and contraception are needed. We report on preclinical studies of the biological properties of sodium cellulose sulfate (Ushercell)(More)
The role of glycosaminoglycans (GAGs) in the invasion of host cells by Chlamydia pneumoniae strains TW-183 and A-03 was investigated and compared with the role of invasion by C. trachomatis serovars L2 and E. The quantities of epithelial and endothelial cell-surface GAGs, as well as chlamydial elementary body (EB)-surface GAGs, were investigated. When(More)
The in vitro activity of gentamicin, tobramycin, kanamycin, and amikacin in combination with ampicillin was determined against aminoglycoside-resistant group B streptococci. Synergy in each combination was determined by quantitative kill curves and demonstrated in all the combinations tested.
BACKGROUND Tobramycin is a critical cystic fibrosis treatment however it causes ototoxicity. This study tested d-methionine protection from tobramycin-induced ototoxicity and potential antimicrobial interference. METHODS Auditory brainstem responses (ABRs) and outer hair cell (OHC) quantifications measured protection in guinea pigs treated with tobramycin(More)
A passive hemagglutination test devised for diagnosis of trench fever was easily performed and highly sensitive and specific. Tanned sheep erythrocytes were sensitized with soluble antigen from Rochalimaea quintana. The test detected antibody in six of seven cases of primary infection and in four cases of late, relapsed trench fever. Titers of antibody(More)
PROBLEM Secretory leukocyte protease inhibitor (SLPI) is an innate immune peptide present on the genitourinary tract mucosa that has antimicrobial activity. In this study, we investigated the interaction of SLPI with Neisseria gonorrhoeae. METHOD OF STUDY ELISA and far-Western blots were used to analyze binding of SLPI to gonococci. The binding site for(More)
Neisseria gonorrhoeae and Chlamydia trachomatis are the common bacteria isolated from bacterial cervicitis and are the leading etiological agents for pelvic inflammatory disease. Neisseria gonorrhoeae cause infection of the mucosa of fallopian tubes in organ culture by attaching to microvilli of nonciliated cells, phagocytosis by these cells, transport(More)
