The species C. sakazakii was identified with primer pair Csakf
(50-ACGCCAAGCCTATCTCCGCG-30) and Csakr (50-ACGGTTGGCGTCATCGTG-
30) and PCR conditions used were denaturation at 94 C
for 3 min, followed by 30 cycles of 94 C for 1 min, annealing at
67 C for 30 s, and 72 C for 1 min. Final elongation was performed
at 72 C for 5 min (Stoop et al., 2009). The amplification products
generated have about 500 bp. C. malonaticus identificationwas also
performed using the primer pair Cmalf (50-CGTCGTATCTCTGCTCTC-
30) and Cmalr (50-AGGTTGGTGTTCGCCTGA-30) (Stoop et al., 2009).
PCR conditions were denaturation at 94 C for 3 min, followed by
30 cycles of 94 C for 1 min, 60 C for 30 s, and 72 C for 30 s.
Elongation was at 72 C for 5 min. The amplification product
generated has 251 bp. Fragment sizes were estimated by comparison
against a DNA ladder (NZYDNA Ladder 1 and NZYDNA Ladder
5, NZYTech).
