Human Salmonella Isolates, 2010 No. 8, August

- The number
of isolates (n=96) showed an increase in comparison with August 2009 (n = 76).
Salmonella Typhimurium phage type RDNC-May 06 (14 in August 2010, 8 in August
2009) was the predominant serotype this month. Uncommon New Zealand serotypes identified this month
included S. Ohio (8 human isolates since 2000)
and S. Typhimurium phage type 208 (2 human isolates since 2000). Salmonella
Apapa and S. Glostrup were isolated for the first time in New Zealand. No
recent overseas travel reported.
- During the
month of August 2010, the Enteric Reference Laboratory confirmed 66 ovine
isolates of Salmonella Brandenburg from the South Island
(2009: 49 ovine isolates). A delay in human cases of S.
Brandenburg has been observed since 1998, with human cases usually
increasing in September and October. Seven human cases were confirmed during
the month of August, 6 of which were from the South Island
(2009: 1 human case).
- A increase
in numbers of S. Typhimurium RDNC-May 06 has been observed over the months of
July and August this year in the Auckland region in comparison with 2009 but
the total number of Salmonella isolates has been on the increase as well: 2009
(148), 2010 (169). This phage type is one of our most common phage type in New Zealand.
