To find out the prevelance of parasitic eggs/larvae of zoonotic importance, 160 faecal samples, 80 soil samples and 80 herbage samples from each of the selected park during four months i.e. from 1St June to 30th September 2007 were collected and examined. The public parks included; 1) Nasir Park, 2) Iqbal Park. Thus in total 640 samples were examined for prevelance of parasitic eggs/larvae of zoonotic importance including faeces, soil and herbage. At the same time 160 faecal samples of pet dogs and cats were collected from the Pet Centre of University of Veterinary and Animal Sciences, Lahore and were examined for the presence of zoonotic parasites. These samples were processed and examined according to the techniques i.e. direct smear method, flotation and Baerman techniques. Five samples of each material were collected every week. The effect of meteorological data was also studied. Overall infection of the parks showed that 118 (37%) out of 320 faecal samples, 44 (27.5%) out of 160 soil samples and 81(51%) out of 160 herbage samples were found positive for parasitic eggs/larvae whereas 243 (38%) out of total 640 samples were found positive for parasitic contamination. One hundred and eighteen (37%) out of 320 faecal samples were found positive in which 72 (61%) were positive for A ncylostoma caninum, 23 (19%) for Toxocara canis, 15 (13%) for Diplidium caninum and 8 (7%) were found positive for others. Out of 160 soil samples 44 (27.5%) were found positive for parasitic infection. Amongst these 31 (70%) were positive for Ancylostoma caninum, 9 (20%) were positive for Toxocara canis and 4 (10%) were positive for other nematodes. Eighty one (51%) out of 160 samples was positive for parasitic infection. Amongst these 48 (59%) were positive for Ancylostoma caninum, 21 (26%) for Toxocara canis and 12 (15%) for others were found positive. The total 243 (38%) out of 640 were found positive for parasitic contamination. Amongst those 53 (22%) were positive for Toxocara canis, 151(62%) for Ancylostoma caninum, 15 (6%) for Diplidium caninum and 24 (10%) for others including Tinia saginata, Strongyloids etc. To find out the prevalence of zoonotic parasites in pet dogs and cats 160 faecal, 80 for dogs and cats each, samples were collected form the pet centre of University of Veterinary & Animal Sciences, Lahore. Among dogs 25 (31%) out of 80 faecal samples were positive for parasitic eggs/larvae and while in cats 23 (29) out of 80 samples were positive for parasitic eggs/larvae. Overall 48(30%) out of 160 faecal samples were found positive for parasitic infection.
