Novel strain of Shigella dysenteriae serotype 7 from India
نویسندگان
چکیده
We describe a strain of Shigella dysenteriae serotype 7 which had novel biochemical and genetic characters. Unlike other S. dysenteriae, it produced gas, fermented mannitol, was a late-lactose fermenter and harboured the set 1A and set 1B genes. The significance of such atypical strains is that they are difficult to identify. If such strains are missed, they could prove to be a serious public health problem because the infectious dose is very low and they may harbour integrons contributing to drug resistance.

Shigella dysenteriae Serotype 1, Kolkata, India
Since July 2002, bacteriologically confirmed shigellosis cases have increased, and multidrug-resistant Shigella dysenteriae serotype 1 strains have reemerged in patients hospitalized with diarrhea in Kolkata, India. The isolated strains of S. dysenteriae 1 showed resistance to chloramphenicol (80%), ampicillin (100%), tetracycline (100%), co-trimoxazole (100%), nalidixic acid (100%), norfloxaci...
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...

We sequenced and analyzed Shigella dysenteriae strain Sd1617 serotype 1 that is widely used as model strain for vaccine design, trials and research. A combination of next-generation sequencing platforms and assembly yielded two contigs representing a chromosome size of 4.34 Mb and the large virulence plasmid of 177 kb. This genome sequence is compared with other Shigella genomes in order to und...
متن کاملHistopathological study of rabbit intestinal mucosa infected with a hybrid strain of Shigella dysenteriae 1 carrying LPS biosynthesis genes of Salmonella enterica serovar typhimurium.
The rfb gene cluster and the rfc gene of Salmonella enterica were introduced earlier into an invasive Shigella dysenteriae 1 strain by triparental cross. Antiserum was raised in rabbit against lipopolysaccharide isolated from the hybrid strain. Both the hybrid and the invasive S. dysenteriae 1 strain were found to have a titer of 1:2560 while for S. enterica, it was 1:640. Ligated ileal loops w...
متن کاملClonal relationships among Shigella serotypes suggested by cryptic flagellin gene polymorphism.
The presence of cryptic fliC alleles in the genomes of 120 strains representative of the four Shigella species was investigated. One fragment was obtained by PCR amplification of fliC, with a size varying from 1.2 to 3.2 kbp, depending on the species or serotype. After digestion with endonuclease HhaI, the number of fragments in patterns varied from three to nine, with sizes of between 115 and ...
