Huanglongbing (HLB), also known as citrus greening, is the most serious disease affecting production in Asia, Africa, Americas, and Arabian Peninsula. HLB associated with α-Proteobacteria “CandidatusLiberibacter asiaticus” (CLas), “Ca. L. africanus” (CLaf), americanus” (CLam). The Bangladesh industry comprises mandarins, sweet oranges, pummelos, limes, lemons. In 2017-2018, a survey was conduct...
Escherichia coli O157, an etiological agent of hemorrhagic colitis and hemolytic uremic syndrome, is one of the leading worldwide public health threats. Genome sequencing of two O157 strains have revealed that the chromosome is comprised of a 4.1 Mb backbone shared by K-12 and a total of 1.4 Mb O157-specific sequences. Most of the large O157-specific sequences are prophages and prophage-like el...
BACKGROUND The hypervirulent Clostridium difficile ribotype 027 can be classified into subtypes, but it unknown if these differ in terms of severity of C. difficile infection (CDI). Genomic studies of C. difficile 027 strains have established that they are rich in mobile genetic elements including prophages. This study combined physiological studies, electron microscopy analysis and molecular b...
The order Sphingomonadales, containing the families Erythrobacteraceae and Sphingomonadaceae, is a relatively less well-studied phylogenetic branch within the class Alphaproteobacteria. Prophage elements are present in most bacterial genomes and are important determinants of adaptive evolution. An “intact” prophage was predicted within the genome of Sphingomonas hengshuiensis strain WHSC-8 and ...
Staphylococcus aureus clonal complex 398 is a livestock-associated pathogen that poses a worldwide threat because of its ability to colonize and infect both humans and animals. We used high-resolution whole-genome microarrays, prophage profiling, immune evasion cluster characterization and whole-genome sequencing to investigate the roles of prophages in the emerging human-adapted subpopulation ...
Chronological analysis of 125 Vibrio cholerae O139 strains isolated during 1993-2005 in Kolkata revealed the prevalence of two new genotypes of cholera toxin (CT) and novel combinations of ctxB and rstR alleles resulting in variant CTX prophages. One of the new genotypes of ctxB, which first appeared in 1996 with the re-emerged V. cholerae O139 strains that had CTX Calcutta phage, was designate...
