To determine GASTROINTESTINAL PARASITES of pet dogs of Urmia this study was carried out in a peroid of 14 months form April 2005 to June 2006. Two hundered and six fecal samples i.e; 169 and 37 samples from male and female dogs respectively, were collected from small animal’s clinics of Urmia city. The dogs were studeied in two age groups of £6 months and>6 months included number of 60 and 146 respectively. The results indicated that 71 (34.46%) of the specimens have been infected at least by one parasite. The PARASITES were identified as follows: Giardia and Cryptosporidium 6 (2.6%), Hook worm and Toxacara spp 6 (2.91%) and Hook worm, Toxacara spp, Isospora spp 27 (13.1%), 20 (9.7%) and 3 (1.45%), respectively. In this survey 2 (0.97%) were infected to cestoda. Majority of the dog owners (82.2%) were not found to be aware of the potential risk of canine PARASITES to human health and their knowledge were found unsatisfactory.

Examination of faecal samples of 6,430 school children aged between 2 and 20 years, for GASTROINTESTINAL PARASITES using sedimentation and Kato smear techniques was carried out in Benin City, Nigeria between January 1997 and December 1998. Four thousand two hundred and thirty six (65.8%) were infected. Three species of protozoa and 8 species of helminths were recorded as follows: Entamoeba histolytica (6%), Entomoeba coli (4.8%), Giardia lamblia (5.2%), Schistosoma mansoni (2.4%), Fasciola gigantica (2.3%), Taenia sp. (1.3%), Ascaris lumbricoides (17.0%), Enterobius vemicularis (1.5%), Trichuris trichiura (6.8%), Necator americanus (13.9%), and Strongyloides stercoralis (3.9%). Prevalence of infection increased with increase in age to a maximum value of 8.15% among the 6-9 years age group (junior primary pupils) and thereafter decreased with increase in age, to the least value of 28.6% among the 17-20 years old (senior secondary). The nursery pupils recorded the highest prevalence for protozoa and the nematode Ascaris lumbricoides infections while the senior primary pupils had the highest infection rates for the fluke Schistosoma mansoni and for all other nematode PARASITES recorded (apart from Ascaris). The junior secondary pupils recorded the highest prevalence for the liver fluke, Fasicola gigantica while the senior secondary pupils recorded the least prevalence for all the parasitic infections. Infections were significantly high (P<0.05) in the rainy season (April-October) and low in the dry season (November-March). The high infection rate is considered to be due to general poor sanitation in the environment and the poor sanitary habits of children.

Background: Dogs play an important role in transmission of PARASITES and zoonotic diseases, especially in developing countries. We aimed to investigate the prevalence of internal PARASITES in stray and pet dogs in Palestine. Methods: Fecal samples were collected during the period between Jan to May 2019. A total of 150 fecal samples were collected and tested for PARASITES using sedimentation and flotation techniques. The targeted dogs were both pet dogs and stray dogs and were grouped according to gender and age. Results: Although there was no significant difference in infestation between males and females, the prevalence rate of infestation in males was 63. 1% compared to females 72. 4%. Dogs of ages under one year had similar rate of infestation compared to older dogs with a rate of 67. 3% and 67. 4% respectively. Infestations were significantly higher (P<0. 05) in stray dogs 81. 4% compared to pet dogs 48. 4%. The highest infestation rate was with Toxocara canis 46. 0% followed by Dipylidium caninum 23. 0%, Echinococcus spp. 14. 0%, Isosopora canis 9. 0%, Ancylostoma caninum 8. 0%, Giarda spp. 5. 0%, Strongyloides spp. 4. 0%, Trichuris vulpis 3. 0%, and Cryptosporidium spp. 3. 0%. Conclusion: Local dogs in Palestine, especially stray dogs, are infested with different types of intestinal PARASITES that may cause many common and noncommon diseases to humans. To prevent the spread of these PARASITES, future public health should be proposed and applied by authorities to achieve a healthy status of the residents in the country. Health awareness spread among people about the seriousness of the diseases transmitted by dogs must also be activated.

Introduction of ostrich (Struthio camelus domesticus), a new exotic host species to a new ecosystem like Iran, necessitates the study of its infectious diseases including parasitic infestations. For a period of one year, from 2002–03, faecal samples of 254 ostriches on 5 farms located at different parts of Iran, including Garmsar, Semnan province (n = 85); Nashtaroud, Mazandaran province (n = 29); Saveh, Central province (n = 47); Eshtehard, Ghazvin province (n = 8) and around Tehran, Tehran province (n = 85) were examined for GASTROINTESTINAL PARASITES. Our findings revealed the presence of Libostrongylus douglasii in 55% of the examined birds in Nashtaroud and 25% of birds of Eshtehard farms. In the latter farm, 12.5% in the ostriches harboured Heterakis dispar in their alimentary canals. Oocyst of Eimeria sp. was found in ostrich on farm of Garmsar. All these PARASITES are reported for the first time from ostriches in Iran.

Background: Stray cats are considered an important source of various human and animal diseases, particularly diseases of parasitic helminths. We aimed to investigate the distribution of zoonotic species of GASTROINTESTINAL helminths in stray cats in Meshkin-Shahr district in Ardabil Province in the northwest of Iran. Methods: The GASTROINTESTINAL tract of 104 stray cats from villages of Meshkin-Shahr district were provided during 2014-2015. Each GASTROINTESTINAL tract was cut into distinct sections, including esophagus, stomach, small intestine, and large intestine, and each section was examined separately for detection of helminths. Helminths were collected and then identified at the species level after clearing and staining. Results: Overall, 88 out of 104 cats (84. 6%) were found to be infected with at least one GASTROINTESTINAL helminth. The rate of infection for each species was as follows: Toxocara mystax (syn. cati) (49%), Taenia taeniaeformis (44. 2%), Joyexiella pasqualei (32. 7%), Dipylidium caninum (23. 1%), Rictularia cahirensis (4. 8%), and Physaloptera praeputialis (4. 8%). Among these PARASITES, only Ph. praeputialis was collected from the stomach, all other helminths were collected from the small intestine. Conclusion: The results demonstrate a high infection rate of stray cats with zoonotic helminths. The presence of zoonotic species in stray cats, particularly T. mystax, has public health importance.

BACKGROUND & OBJECTIVE: Mesenchymal tumor of the GASTROINTESTINAL tract comprises a diverse group of neoplasms which occurs in adults. With recognition of immunohistochemical profile in recent years, GASTROINTESTINAL stromal tumor (GIST) has been grouped separately from other sarcomas. No therapeutic modality except. Surgey has ever demonstrated definitive evidence of clinical benefit in GIST. These tumors occur most commonly in the stomach, followed by small intestine, and are rare in the colon and rectum and extremely rare in the esophagus. GIST also arises rarely in the omentum, mesentery and peritoneum.CASE: A 69-year-old male was admitted to surgical ward with clinical and CT scan findings of large, movable abdominal mass behind the stomach with probable origin from the pancreas. Explorative laparatomy revealed an 18 x 16 cm mass in lesser omentum. Pathological and immunohistochemical techniques revealed malignant GIST.CONCLUSION: GASTROINTESTINAL stromal tumor should be considered in the differential diagnosis of the abdominal mass.

Supervision on bird's health Care which is on sale in the Isfahan City is of great importance because of its close and direct contact with people. In this study 412 Specimen of feces of the birds which are on sale in bird sellers were tested microscopically for detection of various PARASITES contamination applying standard and regular floatation Method. 41 Cases were positive for PARASITES in cladding 32 cases contaminated with Oocyst of Eimeria equivalent 7.6%. 4 cases contaminated with egg of Raillietina 0.95 percent and 5 cases only contaminated with egg of Ascaridia galli 1.18 percent.

Background: Cats play a crucial role in the epidemiology of GASTROINTESTINAL helminthic PARASITES and also play a major role in transmitting of these PARASITES through faecal contamination of soil, food or water. The aim of this study was to determine the species of GASTROINTESTINAL helminthes PARASITES in stray cats from a rural area of Bandar-e-Anzali, Iran.Method: GASTROINTESTINAL helminthes were collected from 50 necropsied stray cats (Felis catus) after capturing them by trapping from different regions of the city and humanely euthanatized in Bandar-e-Anzali, a port in the Caspian Sea in northern Iran, from March to November 2003.Results: The prevalence of infection was 90%, with those of individual PARASITES being Diplopylidium nolleri 54%, Physaloptera praeputialis 32%, Ancylostoma tubaeforme 20%, Joyeuxiella pasqualei 10%, Toxocara cati 8%, Pterygodermatites affinis 6%, Ancylostoma caninum 4%, and Taenia taeniaeformis 2%. Concurrent infections with two or more PARASITES were recorded in 34% of the individuals. In relation to the sex, the differences were not significant.Conclusion: P. praeputialis, T. cati, D. nolleri and sometime J. pasqualei are the commonest Helminthes in cats. This is the first reported isolation of P. affinis and A. caninum infections from cats in Iran.
