Emergence of zoonotic infectious diseases represent one of the main threats to people worldwide. To properly understand and prevent zoonoses is fundamental to study their epidemiology and the possibility of spillover events, especially for commercially intensive domestic animals and humans. Here, we studied 210 wild birds from the “Ipucas” region, which consists of fragments of the Amazon Forest interspersed with fragments of the “Cerrado” that is subject to seasonal flooding and 75 domestic birds from neighboring poultry farming. Then, we molecularly diagnosed
Salmonella
and
Chlamydia
from wild birds and poultry. Among the wild birds, four were diagnosed with
Chlamydia psittaci
and 23 with
Salmonella
spp., while we detected 15 poultry infected by
Salmonella
spp. and no poultry with
C. psittaci
. We highlighted the common infections of wild and domestic birds in an anthropologically modified environment and potential spillover of
Salmonella
pathogens among wild and livestock birds. Those infections can harm the health of native and domestic species.
