A. N. Al Khalaf helminthes , Egret , Egretta alba , Saudi ArabiaExamination of the alimentary tracts of 9 Great Egret (Egretta alba) found freshly died in their inland places around Al-Qassim area during migration season in September and October revealed infection by 6 species of helminths. The extracted parasites were include two cestode worms, three nematodes and one acanthocephala. They were identified as Uniciuna species, Choano-taenia, Subulura species, Contrac-aecum species, Syphacia species and Polymorphus species. None of any examined carcass appears free from infection. The rate of distribution of the parasite in the examined birds was varied between 66.6%, 11.1%, 44.4%, 44.4%, 66.6% and 2.2 % for the previous parasites respectively. The rate of Parasite burden for each species was moderate to low, as it was 3.4, 2.0, 2.65, 3.25, 5.16 and 4.5 from the previous parasites respectively. None of these parasites was published previously in Saudi Arabia as infect this type of Egret. Their morphological characters and their distribution were described in detail

In this study a total of 200 stray dogs housed in Safe Harbor Animal Rescue and Clinic (SHARC), South Florida, USA were clinically and parasitologically examined for intestinal helminthes. In this investigation, dogs were clinically examined and monitored for intestinal parasites for 6 successive weeks, treated with specific drugsand investigated for the possibility of reinfestation with intestinal parasites within theclosed quarters of the animal shelter environment. Fecal floatation technique revealed three types of parasitic eggs in fecal samples of 46 (23%) dogs, including Ankylostoma spp. 30 (15%), Toxocara canis 10 (3.5%), and Dipylidium caninum 6 (3%). Clinical examination of investigated dogs revealed bloody diarrhea associated with abdominal pain, anemia, poor hair coat and the presence of segments of tapeworms approximately in the size of grain of rice in the feces of some dogs. Some dogs showed frequent cough. Some dogs that were tested negative for Ankylostoma spp. and Toxocara canis tested positive later indicating definite contamination in the environment of the shelter. Some dogs developed tapeworm infestation during this study indicting the presence of infective flees in contact dogs. Control measures and therapy were discussed.
