Shigella boydii serotypes in Egypt.
While Shigella boydii serotypes have been reported on numerous occasions from many parts of the world (Weil and Saphra, 1953), they rarely have comprised more than a small proportion of the total number of Shigella found, and knowledge of their distribution, cultural characteristics, immunological relationships and pathogenicity is incomplete in some respects. This is particularly true of the m...
متن کاملIdentification and characterization of Shigella boydii 20 serovar nov., a new and emerging Shigella serotype.
Analysis of 163 putative Shigella isolates from Canada and the USA showed biochemical reactions consistent with Shigella species, although none of the isolates reacted with antiserum raised against any of the well-established or provisional Shigella serotypes. All these isolates, provisionally designated serotype SH108, were positive for the ipaH gene and the invasion-associated locus. All ferm...
متن کاملCharacterization of Shigella dysenteriae serotypes 11, 12, and 13.
We conducted serologic and biochemical studies on strains of three provisional Shigella serotypes. Included were 19 strains of serotype 3873-50 from three countries (1 from Mexico, 1 from Netherlands Antilles, and 17 from the United States), 13 strains of serotype 3341-55 from three countries (1 from Canada, 1 from Bulgaria, and 11 from the United States), and 19 strains of serotype 19809-73 fr...
متن کاملIncrease in drug resistance among Shigella dysenteriae, Sh flexneri, and Sh boydii.
Two thousand three hundred and seventy strains of Shigella dysenteriae, Sh flexneri, and Sh boydii isolated in England and Wales from 1974 to 1978 were tested for resistance to 12 antimicrobial drugs. Eighty per cent of strains were resistant to one or more drugs, with sulphonamide resistance occurring most frequently. Resistance to streptomycin, tetracycline, ampicillin, and chloramphenicol in...
متن کاملMolecular and phenotypic characterization of potentially new Shigella dysenteriae serotype.
From September 1997 to November 1998, the French National Center for Salmonella and Shigella received 22 Shigella isolates recovered from 22 different patients suffering from dysentery. None of these isolates reacted with any of the antisera used to identify established Shigella serotypes, but all of them agglutinated in the presence of antisera to a previously described potentially new Shigell...
