The incidence of meticillin resistant Staphylococcus aureus (MRSA) remains stable and Clostridium difficile infection (CDI) continues to decline in England, while meticillin susceptible Staphylococcus aureus (MSSA) continues to rise, the latest data from Public Health England (PHE) shows.

According to the latest PHE quarterly trends report in MRSA and MSSA, Gram-negative bacteraemia and CDI, the incidence rates of hospital-onset and community-onset MRSA bacteraemia in the period July to September 2018 were similar to those in the same period last year, at 0.8 cases per 100,000 bed-days and 1.5 cases per 100,000 population.

In relation to CDI, comparing July to September 2017 and July to September 2018, both counts and incidence rate (per 100,000 population) of all reported CDI decreased by 2%; from 3657 to 3592 cases and 26.1 to 25.6, respectively.

However, the incidence rate of hospital-onset MSSA bacteraemia increased by 7% from 9.0 to 9.6 cases per 100,000 bed-days while the incidence rates of community-onset cases remained at 15.5 cases per 100,000 population when comparing the same two time periods.

The incidence rate of all reported E. coli bacteraemia has also continued to increase. Comparing July to September 2018 to the same period last year shows a 5% increase in both counts and incidence rate of all reported cases.

Meanwhile, between April to June 2017 and July to September 2018, there was a 17% increase in the counts of Pseudomonas aeruginosa bacteraemia, and a 22% increase in the counts of all reported Klebsiella spp. bacteraemia cases.
