Kurzfassung:
In the present study, we analyzed the presence of antibodies to four different influenza viruses ( pH 1N1, hH 1N1, sw H 1 N 1, and sw H 3 N 2) in the sera of 2094 backyard pigs from M exico C ity. The sera were obtained between 2000 and 2009. Objectives The aim of this study was to perform a retrospective analysis of the 2000–2009 period to determine the seroprevalence of antibodies against pH 1N1, hH 1N1, sw H 1 N 1, and sw H 3 N 2 viruses in sera obtained from backyard pigs in M exico C ity. Methods Antibody detection was conducted with hemagglutination inhibition assay ( HI ) using four influenza viruses. We used linear regression to analyze the tendency of antibody serum titers throughout the aforementioned span. Results We observed that the antibody titers for the pH 1 N 1, sw H 1 N 1, and sw H 3 N 2 viruses tended to diminish over the study period, whereas the antibodies to hH 1 N 1 remained at low prevalence for the duration of the years analyzed in this study. A non‐significant correlation ( P 〉 0·05) between antibody titers for pH 1 N 1 and sw H 1 N 1 viruses was observed (0·04). It contrasts with the significance of the correlation (0·43) observed between the sw H 1 N 1 and sw H 3 N 2 viruses ( P 〈 0·01). Conclusions Our findings showed no cross‐antigenicity in the antibody response against the same subtype. Antibodies against pH 1 N 1 virus were observed throughout the 10‐year study span, implying that annual strains shared some common features with the pH 1 N 1 virus since 2000, which would then be capable of supporting the ongoing presence of these antibodies.
