Immunomagnetic separation and PCR detection show Shigellae to be common faecal agents in children from urban marginal communities of Costa Rica
Achí Araya, María Rosario; Mata Jiménez, Leonardo; Siles Díaz, Xinia; Lindberg, Alf A. (1996)Culture and immunomagnetic separation-polymerase chain reaction assays (IMS-PCR) were used to isolate and identify Shigella flexneri, S. dysenteriae type I and S. sonnei in faeces from 250 children up to 5 years and from ... -
Rapid and sensitive detection of Shigella sonnei in feces by the use of an O-antigen-specific monoclonal antibody in a combined immunomagnetic separation-polymerase chain reaction assay
Achí Araya, María Rosario; Lindberg, Alf A. (1996-08)OBJECTIVE: The aim of the present work was to develop a rapid, specific and highly sensitive diagnostic method for the detection of Shigella sonnei directly from stool samples. DESIGN AND METHODS: An immunomagnetic ... -
Serum Antibody Titres to Shigella Lipopolysaccharides and Invasion Plasmid Antigens in Healthy Costa Rican and Swedish Women
Achí Araya, María Rosario; Mata Jiménez, Leonardo; Lindberg, Alf A. (1994)Specific serum antibody titres to defined lipopolysaccharides (LPS) of Shigella spp. and Salmonella serogroup B (BO) and Shigella invasion plasmid antigens (Ipa) were determined by enzyme immunoassays in healthy Costa Rican ... -
Trites of class-specific anitbodies against Shigella and Salmonella lipopolysaccharide antigens in colostrums and breast milk of Costa Rican, Swedish and Vietnamese mothers
Achí Araya, María Rosario; Dac Cam, Phung; Forsum, Urban; Karlsson, Kerstin; Sáenz, Patricia; Mata Jiménez, Leonardo; Lindberg, Alf A. (1992)Enzyme immunoassays (El A) were used to estimate titres of class-specific antibodies against purified and chemically defined phenol-water-extracted lipopolysaccharide (LPS) antigens of Salmonella serogroup B (BO), Shigella ...
