“…According to the Chilean governmental reference laboratory ISP (Public Health Institute), from a total of 917 human salmonella isolates obtained from sick persons during 1994, 84.4% belonged to salmonella serogroups B and D (FernaÂ ndez, 1995). Although the number of pigeons sampled in the present study does not allow a de® nitive assessment of the prevalence of salmonella in the feral pigeon population of Santiago, we believe that further epidemiological studies are needed in view of the possible importance of this agent both for the commercial poultry and the human populations (Niida et al, 1983).…”

“…During the past 5 years, more and more people have asked us about methods of controlling this population, mainly because of damage to private and/or public possessions . On the other hand, the role of pigeons in the transmission of diseases to both humans and domestic species has been well documented by different authors (Weber et al, 1979;Alexander et al, 1982Alexander et al, , 1985Haag & Gurdan, 1990;Orlandella et al, 1992).…”

A total of 100 free-living urban pigeons (Columba livia) were captured in the city of Santiago, Chile, in order to evaluate, for the ® rst time, their health status. Negligible antibody titres (1 to 3 log2) were detected in 22% of the birds against a strain of the paramyxovirus (PMV) serotype 1. No pigeons had antibodies against PMV serotype 7 and avian in¯uenza. Salmonella sp. belonging to serogroups B and D were isolated from the intestinal tract of three pigeons (3%). The protozoa Haemoproteus columbae, Plasmodium sp., and Leucocytozoon sp. were not detected in any pigeons. Trichomonas gallinae was detected in 11%, without observation of either clinical signs or gross pathological changes at necropsy. Sixty-seven percent of the birds showed the presence of the chewing lice Columbicola columbae and Campanulotes bidentatus compar, and 1% harboured the mite Laminosioptes cysticola. Seven species of nematodes were identi® ed. The frequency at which each species was detected was; Tetrameres sp. (14%), Capillaria annulata (1%), Capillaria columbae (11%), Capillaria obsignata (1%), Ascaridia columbae (5%), Dispharynx spiralis (2%), and Gongylonema ingluvicola (2%). The class Cestoda, found in one pigeon, was represented by the species Aporina delafondi. No trematodes were detected in the sampled birds.
