Journal ArticleDOI
Performance comparison of benchtop high-throughput sequencing platforms
Nicholas J. Loman,Raju Misra,Timothy J. Dallman,Chrystala Constantinidou,Saheer E. Gharbia,John Wain,John Wain,Mark J. Pallen +7 more
TL;DR: The performance of these instruments were compared by sequencing an isolate of Escherichia coli O104:H4, which caused an outbreak of food poisoning in Germany in 2011, and the MiSeq had the highest throughput per run and lowest error rates.
Journal ArticleDOI

Nick Andrews,Julia Stowe,Freja C M Kirsebom,Samuel E. Toffa,T S Rickeard,Eileen Gallagher,Charlotte Gower,Meaghan Kall,Natalie Groves,Anne Marie O’Connell,David Simons,Paula Blomquist,Asad Zaidi,S. Nash,Nurin Iwani Binti Abdul Aziz,Simon Thelwall,Gavin Dabrera,R. Myers,Gayatri Amirthalingam,Saheer E. Gharbia,Jeffrey C. Barrett,Richard Elson,Shamez N Ladhani,Neil M. Ferguson,Maria Zambon,Colin Campbell,Kevin K. Brown,Susan Hopkins,Meera Chand,Mary Ramsay,Jamie Lopez Bernal +30 more
TL;DR: Primary immunization with two doses of ChAdOx1 nCoV-19 or BNT162b2 vaccine provided limited protection against symptomatic disease caused by the omicron variant, but that protection waned over time.
Journal ArticleDOI
Biochemical and chemical studies on strains designated Prevotella intermedia and proposal of a new pigmented species, Prevotella nigrescens sp. nov.
Haroun N. Shah,Saheer E. Gharbia +1 more
TL;DR: It is proposed that a new species, Prevotella nigrescens, should be created for the genetically distinct group of strains that hybridized with strain ATCC 33563T, which is designated the type strain of P. Nigrescens.
Journal ArticleDOI
The use of a 16S rDNA directed PCR for the detection of endodontopathogenic Bacteria
TL;DR: The study evaluates a 16S rDNA directed polymerase chain reaction (PCR) to detect and differentiate bacteria in necrotic root canal samples to focus on species that are fastidious concerning culture or are difficult to differentiate after culturing by biochemical methods.
Journal ArticleDOI
Characterization of Prevotella intermedia and Prevotella nigrescens isolates from periodontic and endodontic infections.
Saheer E. Gharbia,Markus Haapasalo,Haroun N. Shah,Anja Kotiranta,Kari Lounatmaa,Michelle A. Pearce,Deirdre A. Devine +6 more
TL;DR: The results show that P. intermedia and P. nigrescens may have different site specificities and surface properties and thus emphasize the need for accurate identification of these two species for the evaluation of their role in the pathogenesis of oral infections.
