Biology of Haemophilus ducreyi.
The etiological agent of the sexually transmitted genital ulcer disease chancroid was first described in 1889 by Auguste Ducrey following repeated autoinoculation of purulent ulcer material from a series of patients. The organism was isolated on artificial media a decade later but has remained difficult to isolate consistently, resulting in controversy over its characteristics and role as the c...
متن کاملProperties of single cardiac Na channels at 35 degrees C
Single Na channel currents were recorded in cell-attached patches of mouse ventricular myocytes with an improved patch clamp technique. Using patch pipettes with a pore diameter in the range of 200 nm, seals with a resistance of up to 4 T omega were obtained. Under those conditions, total noise could be reduced to levels as low as 0.590 pA rms at 20 kHz band width. At this band width, propertie...
متن کاملThe incubation of laminin, collagen IV, and heparan sulfate proteoglycan at 35 degrees C yields basement membrane-like structures
Three basement membrane components, laminin, collagen IV, and heparan sulfate proteoglycan, were mixed and incubated at 35 degrees C for 1 h, during which a precipitate formed. Centrifugation yielded a pellet which was fixed in either potassium permanganate for ultrastructural studies, or in formaldehyde for Lowicryl embedding and immunolabeling with protein A-gold or anti-rabbit immunoglobulin...
متن کاملChancroid and Haemophilus ducreyi.
Haemophilus ducreyi is the causative agent of chancroid, one of the genital ulcerative diseases. H. ducreyi is the major cause of genital ulcer disease in Africa and Southeast Asia and is of increasing concern in the United States. Definitive diagnosis of chancroid requires the isolation and identification of H. ducreyi, but isolation of this organism is difficult and the available medium is no...
متن کاملTyping Haemophilus ducreyi by indirect immunofluorescence assay.
Rabbits were inoculated with untreated whole cells of 16 strains of Haemophilus ducreyi. Homologous titres in an indirect immunofluorescence test ranged from 1/320 to 1/1280. No cross reactions, or very few, were observed between antisera to these strains and 22 other (possible taxonomically related) species, strains, and genera. A large diversity in types of antigen was observed among the stra...
