Adjuvant Activity of N -Acetyl Muramyl Dipeptides for the Induction of Delayed-Type Hypersensitivity to Azobenzenearsonate- N -Acetyl- l -Tyrosine in Guinea Pigs
Infection and Immunity - Tập 29 Số 3 - Trang 1193-1196 - 1980
Ichiro Azuma, Keiichi Kamisango, Ikuo Saiki, Yoshiro Tanio, Shigeru Kobayashi, Yuichi Yamamura
The adjuvant activity of 23 kinds of synthetic N -acetyl muramyl dipeptide analogs on the induction of delayed-type hypersensitivity to azobenzenearsonate- N -acetyl- l -tyrosine was examined in guinea pigs.
A recombinant 15-kilodalton carboxyl-terminal fragment of Plasmodium yoelii yoelii 17XL merozoite surface protein 1 induces a protective immune response in mice
Infection and Immunity - Tập 61 Số 6 - Trang 2462-2467 - 1993
T M Daly, Carole A. Long
Since the developmental stages of malarial parasites which replicate within erythrocytes are responsible for the morbidity and mortality associated with this disease, antigens produced by these stages have been proposed as candidates for a vaccine. One surface protein of merozoites (MSP-1) has been shown to immunize both rodents and primates against virulent challenge infection in experime...... hiện toàn bộ
Toll-Like Receptor 2-Dependent Protection against Pneumococcal Carriage by Immunization with Lipidated Pneumococcal Proteins
Infection and Immunity - Tập 82 Số 5 - Trang 2079-2086 - 2014
Kristin Moffitt, Mojca Škoberne, A. Howard, L. Cristina Gavrilescu, Todd M. Gierahn, Scott Munzer, Bharat L. Dixit, Paul J. Giannasca, Jessica B. Flechtner, Richard Malley
ABSTRACTInfections withStreptococcus pneumoniaecause substantial morbidity and mortality, particularly in children in developing nations. Polysaccharide-conjugate vaccines provide protection against both invasive disease and colonization, but their use in developing countries is limited by restri...... hiện toàn bộ
Comparative Virulence of Streptococcus pneumoniae Strains with Insertion-Duplication, Point, and Deletion Mutations in the Pneumolysin Gene
Infection and Immunity - Tập 67 Số 2 - Trang 981-985 - 1999
Anne M. Berry, Abiodun D. Ogunniyi, D. Craig Miller, James C. Paton
ABSTRACT Pneumolysin is a 471-amino-acid toxin produced by Streptococcus pneumoniae which has both cytolytic and complement activation properties. We have constructed a derivative of the type 2 S. pneumoniae strain D39 in which the portion of...... hiện toàn bộ

Role of Streptococcus gordonii Amylase-Binding Protein A in Adhesion to Hydroxyapatite, Starch Metabolism, and Biofilm Formation
Infection and Immunity - Tập 69 Số 11 - Trang 7046-7056 - 2001
Jeffrey Rogers, Robert Palmer, Paul E. Kolenbrander, Frank A. Scannapieco
ABSTRACT Interactions between bacteria and salivary components are thought to be important in the establishment and ecology of the oral microflora. α-Amylase, the predominant salivary enzyme in humans, binds to Streptococcus gordonii , a primary colonizer of the tooth. Previous studies have i...... hiện toàn bộ
Characterization of an amylase-binding component of Streptococcus gordonii G9B
Infection and Immunity - Tập 60 Số 11 - Trang 4726-4733 - 1992
Frank A. Scannapieco, G G Haraszthy, M I Cho, Michael J. Levine
The goal of the present study was to begin characterizing the amylase-binding component(s) on the surface of Streptococcus gordonii G9B. Alkali extracts but not phenol-water extracts of this bacterium inhibited 125I-amylase binding to S. gordonii G9B. To identify the bacterial components involved in amylase binding, the alkali extract was subjected to affinity chromatography on amylase-Sep...... hiện toàn bộ
Polymorphonuclear leukocyte adherence to nylon: effect of oral corticosteroids
Infection and Immunity - Tập 26 Số 2 - Trang 542-546 - 1979
J. McGillen, John Phair
The effect of orally administered glucocorticoids on polymorphonuclear leukocyte adherence was studied by using the nylon fiber adherence assay. Inhibition of adherence 4 h after administration of the agent was confirmed, and in addition, augmentation of adherence was noted 24 h after ingestion of prednisone. Crossover studies revealed inhibition and augmentation to be cell associated as w...... hiện toàn bộ
Eukaryotic SNARE VAMP3 Dynamically Interacts with Multiple Chlamydial Inclusion Membrane Proteins
Infection and Immunity - Tập 89 Số 2 - 2021
Duc‐Cuong Bui, Lisa M. Jorgenson, Scot P. Ouellette, Elizabeth A. Rucks
Chlamydia trachomatis , an obligate intracellular pathogen, undergoes a biphasic developmental cycle within a membrane-bound vacuole called the chlamydial inclusion. To facilitate interactions with the host cell, Chlamydia modifies the inclusion ...
Characterization of rickettsial attachment to host cells by flow cytometry
Infection and Immunity - Tập 60 Số 5 - Trang 2030-2035 - 1992
H. Li, David H. Walker
The mechanisms of rickettsial attachment have been studied by measuring quantitative changes in rickettsial binding to host cells by flow cytometry after different treatments of the rickettsiae and host cells. Time-dependent binding of Rickettsia conorii to host cells was demonstrated by the increasing intensity of host cell surface fluorescence of rickettsia-host cell combinations when ex...... hiện toàn bộ
