Prevalence of zoonotic and other gastrointestinal parasites in police and house dogs in Alexandria, Egypt

Aim: This work estimates the gastrointestinal parasites of police and house dogs in Egypt with reference to its zoonotic risk. Materials and Methods: Fecal samples of 180 from police and house dogs were collected and then examined by different flotation and sedimentation techniques. Results: Prevalence of gastrointestinal parasites in police dogs was 7.5% and, in house dogs was 40%. Fecal examination of 120 police dogs revealed Toxocara canis eggs in 0.8%, Ancylsotoma caninum 1.7%, Trichuris vulpis 0.8 %, Cystoisospora canis 4.2% and Giardia species1.7%. Examination of 60 house dogs revealed Toxocaracanis eggs in 5% and Toxoascaris leonina 1.7 %, Cystoisospora canis 3.3%, Giardia species 31.7%, Entamoeba histolytica 18.3% and Cryptosporidium spp. 1.7%. Furthermore, age, sex, uncooked feed and communal housing revealed significant enteric parasite (P <0.05). Moreover, the zoonotic risks of police and house dogs were T. canis, A. caninum, T. vulpis, Giardia species, E. Histolytica and Cryptosporidium species. The puppies are representing the most zoonotic risk. Conclusion: In spite of, hygienic measures, regular deworming and high quality feeding of police and house dogs, a range of different parasites were recorded in this work. Parasitic zoonosis from police and house dogs has to be considered, especially for dog trainers and owners.
