Parasitological characterization of urban pigeons (Columba livia): a public health problem in Cuenca-Ecuador. 2019

Public health

Abstract

The pigeons’ population growth in urban areas has become an evident problem for public health and Cuenca city isn’t the exception.   A large number of Castilla pigeons (Columbia Livia), have everyday contact with people that life and settled in the urban area. Another critical point of bird overpopulation is the conflict with homeowners that share their habitat with them. This study identifies food markets and public squares as the most vulnerable places where this problem occurs. Food markets are a sensible place due the risks of contamination of the human consumption products. This critical aspect involves the transmission of a great number of diseases caused by endoparasites and ectoparasites. The study selected a significant sample of pigeons’ population, in the 9 de Octubre Urban Market. These animals were study through direct microscopic analysis and observations. For endoparasites diagnostic, a coproparasitary evaluation was made. All of these birds have a high presence of Phthiraptera lice among others arthropods that are considered zoonotic vectors; as well half of them live with high levels of endoparasites in their intestines. It is concluded that pigeons are transmitters of several zoonotic diseases such as: Chlamydia, Salmonellosis, Rizonosis and Colibacillosis; so it is important to take preventive measures to prevent infections, as well to promote the control the increase of its population in the city of Cuenca-Ecuador
