Table 3.

Prevalence of the three pathogens analyzed in the feral pigeon population in Madrid, sampled at three different times.

Sampling time Chlamydophila psittaci Campylobacter jejuni Campylobacter coli
Nov. 2006 59.7%a (37/62) 81.8%b (36/44) 0% (0/44)
May 2007 37.0%a (10/27) 86.4%b (19/22) 4.5% (1/22)
Nov. 2007 51.8%a (14/27) 35.7%b (10/28) 0% (0/28)
Overall 52.6% (61/116) 69.1% (65/94) 1.1% (1/94)

Presence of the pathogens was determined by PCR analysis and sequence alignments with Genbank (see Methods).

a Statistically significant differences among sampling time for Chlamydophila psittaci: November 2006- May 2007 (p = 0.030); May 2007- November 2007 (p = 0.049); November (2006-2007)- May 2007 (0.047).

b Statistically significant differences among sampling time for Campylobacter jejuni: November 2006- May 2007 (p = 0.032); May 2007- November 2007 (p = 0.001); November 2006- November 2007 (p = 0.001); November (2006-2007)- May 2007 (0.001).
