Figure 1: Distribution of the most likely infecting serogroups according to the species sampled.
Icterohaemorrhagiae most likely infecting serogroup (n=59), followed by Autumnalis (n=8). Most uncommon serogroups found were Ballum, Pyrogenes, Canicola, Tarassovi, Grippotyphosa, Celledoni and Australis, with only one reaction each. Co-agglutinations represented 17.7% of all positive reactions, hampering the identification of the most likely infecting serogroup in 16 samples.
Regarding the sampling sites (Appendix 1), the sample sizes varied from 459 (location 9) to 4 (location 11). Location 9 comprised the garbage dump close to the airport, where 435 egrets were captured. Cats and dogs were captured in all sampling locations. The sampling location 6 (TrĂªs Paus village; n = 17) was the one with higher percentage of seroreactive animals (35.3% of all positive samples), and location 11 (DPV village, an irregular settlement; n = 4) presented no seroreactive animals. The proportion of seroreactive animals according to the sampling locations is presented on Figure 2.
