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.
