Summary

The number of isolates (n=61) showed a significant decrease in comparison with October 2010 (n=110). Salmonella enterica subsp. I ser 4,[5], 12 : i : - was the predominant serotype (1% in October 2010, 8% in October 2011). Uncommon New Zealand serotypes identified this month included S. Typhimurium phage type 141 which has not been confirmed by ERL since 1996 (14 human isolates between 1992-1995). Salmonella Enteritidis phage type 47 (recent travel to China) and S. Typhimurium phage type U311 (no travel history reported) were isolated for the first time in New Zealand. Salmonella Typhimurium has been the most common serotype confirmed by ERL for many years, usually representing between 44% to 56% of the Salmonella serotypes confirmed by ERL but this month this serotype only represented 38%.
