Multilocus sequence typing database for Streptococcus agalactiae contains a spurious allele of the transketolase gene

ABSTRACT The tkt (transketolase) gene is one of the seven gene fragments used in the multilocus sequence typing (MLST) system for Streptococcus agalactiae.We discovered that the tkt_134 allele is derived from a homologous gene Green gaint (which we designate tktX) that is not present in all S.agalactiae; all known strains that contain a match to th

Estimating ventilation rates in rooms with varying occupancy levels: Relevance for reducing transmission risk of airborne pathogens.

BackgroundIn light of the role that airborne transmission plays in the spread of SARS-CoV-2, as well as the ongoing high global mortality from well-known airborne diseases such as tuberculosis and CAL CITRATE measles, there is an urgent need for practical ways of identifying congregate spaces where low ventilation levels contribute to high transmis
