Abstract

Columba livia domestica
pigeons were collected from Ismailia city, Egypt, during the year 2017.
They were found to be infected by intestinal helminths, two cestodes, Raillietina
echinobothrida
and Cotugnia polyacantha and a nematode, Ascaridia columbae. The
heavy metals levels (Mn, Zn, and Fe) in pigeon's muscles and intestine, in
addition to helminths, were measured. R. echinobothrida revealed the
highest in heavy metals accumulation compared to C. polyacantha and A.
columbae. Bioaccumulation factor was most obvious and dominant in muscles
than intestine of infected pigeons in respect to R. echinobothrida\ C.
livia model ranked in concentration from highest to lowest as follows:
(Mn>Zn>Fe), followed by A. columbae\ C. livia model. R.
echinobothrida /C. livia , C. polyacantha/C. livia,
and A. columbae /C. livia are considered effective models
for monitoring heavy metals pollution for Mn, Zn, and Fe, especially in areas
where pollution levels are still relatively low, and have an essential role in
bioremediation of heavy metals accumulation in pigeon's tissues. This study
also emphasized how environmental science and parasitology might profit from
each other. Further studies should be executed in studying the role of pigeon's
helminths in monitoring heavy metals pollution.
