Gastrointestinal helminths of stray dogs in Erzurum province: prevalence and risk to public health

Dogs have an important role in public health due to their close contact with humans and living in common areas. This study was aimed to investigate the presence and prevalence of gastrointestinal system helminths in stray dogs in Erzurum province. Gastrointestinal helminth eggs were detected in a total of 190 out of 446 (42.6%) in stray dogs in Erzurum province. In the study, taeniid eggs (17.71%, 79/446), T. canis (16.82%, 75/446), T. leonina (12.78%, 57/446), Linguatula spp. (4.48%, 20/446), spiny-headed worms (2.91%, 13/446), hookworms (2.69%, 12/446), Alaria spp. (1.12%, 5/446) and Trichuris spp. (0.22%, 1/446) eggs were observed. In addition, proglottid structures of Mesocestoides spp. (3.14%), Taenia spp. (2.69%), and D. caninum (1.12%), adults of Alaria spp. (0.22%), T. canis (0.22%), and T. leonina (0.22%) were detected. According to the results of the study, zoonotic parasites including taeniid cestodes, T. canis, Linguatula spp., spiny-headed worm, hookworm, Alaria spp., and Trichuris spp. were common in stray dogs in the province. Public health risks can be reduced by regular deworming of dogs, proper management of the process, prevention of environmental contamination with dog feces, and proper enforcement of sanitation protocols.
