Inadequate infection control and improper wound-care practices likely led to this 28-month-long outbreak of severe infections in a skilled nursing facility. Whole genome sequencing and phylogenetic analysis suggested that intrafacility transmission of a single highly transmissible GAS strain was responsible for the outbreak in facility A. Integration of genomic epidemiology tools with traditional epidemiology and infection control assessments was helpful in investigation of a facility-wide outbreak.

High rates of carriage of group B streptococci were found among men (38%) and women (42 3 %) attending a clinic for sexually transmitted diseases. Swabs from the perineal/ anorectal area gave the highest isolation rate and those from the urethra the lowest. The subpreputial sac was an important site for carriage of the organism, and there was a strong association between streptococcal isolation and balanitis. Of 92 couples studied, neither partner was colonised with group B streptococci in 36. In a further 36 one or other was colonised and in 20 both were colonised. Serotyping and phage typing showed that only three of these 20 couples were colonised with similar strains of the organism.

SummaryThe Jembec/Neigon transport-and-culture system for the rapid diagnosis of gonorrhoea has been assessed by 167 sets of investigations in 128 named female contacts of infected men. The system offers the same advantages of efficiency and speed as the Transgrow transport-and-culture sysyem, but it is also more flexible and much less time-consuming. IntroductionThe Transgrow transport-and-culture system, when
