  The genera Cryptosporidium and Giardia are among the most common protozoal parasites causing small intestinal abnormalities of dogs.  In this study, 200 fecal samples of herd and guard dogs were collected randomly from different rural areas around Mahabad city and referred to the laboratory after stabilization with formalin and polyvinyl alcohol solutions. Samples were microscopically studied using concentration method followed by the Trichrome-Gumurian and modified Ziehl-Neelsen staining techniques. In general, 9 (4.5%) and 31 (15.5%) of the studied dogs were infected with Cryptosporidium and Giardia respectively. The highest incidence of cryptosporidium was observed in dogs less than 6 months (10.43%) and the lowest incidence was in the age group more than 4 years (1.54%). The highest levels of Giardia infection were found in the 6-12 months age group (25%) and the lowest in the 1-4 years age group (8.62%). The prevalence of infection with cryptosporidium and giardia in male dogs was 4.67% and 14.95%, respectively, and 4.30% and 16.13% in female dogs, respectively. The prevalence of both protozoa in male and female dogs as well as in different age groups was not statistically significant. There were no significant relation between age and gender with prevalence of both parasites. However, the level of infection with both Cryptosporidium and Giardia protozoa in dogs with inappropriate sanitation was higher than those with proper sanitary status, but this difference was not statistically significant.

  Cryptosporidium parvum is an enteric pathogen of a broad range of animals including ruminants. It is also important in terms of public health due to its transmission from animals to humans. The purpose of the present study was to determine the infection rate of this parasite in lambs raised in farms of Jovein area as a center of sheep production in khorasan-razavi province. At first, some sheep flocks were selected randomly, then fecal samples were collected from the rectum of 300 lambs with the age of 10 days to two months during four seasons between summer 1393 to spring 1394 (July 2014 to May 2015). After recording the sampling time, age, sex, and presence or absence of clinical signs of diarrhea in studied lambs, the samples were transported to the parasitology laboratory. Smears were prepared and stained by modified Ziehl-Neelsen method and examined by light microscopy using magnification of 100× (oil immersion). The results of 150 cases of diarrheic and 150 cases of non- diarrheic stools showed that the infection rate is 3% (9 positive samples). Two (1.3%) and 7 (4.6%) positive samples belonged to diarrheic and non- diarrheic lambs, respectively. The Chi-square test revealed no statistically significant correlation between the protozoan infection rate with diarrhea, age, sex and season of sampling. Although the cryptosporidium infection rate in lambs were relatively low in Jovein area, but sheep should not be overlooked as a possible source of infection that could threaten public health.   Manuscript profile

  Cryptosporidium is a small coccidian parasite invaded and replicated within the epithelial cell lining of digestive, respiratory, and conjunctiva organs of vertebrates. Cryptosporidium is an intracellular and exocytoplasmic organism. It has been shown to be an important cause of enterocolitis and self-limited diarrhea in numbers of animals with defect in their immunity system. In this survey, we examined 419 fecal samples including sheep and goats population of Mahabad city, Iran. Forty nine samples of this examined animals (17 samples of sheep and goats are under 1 year old, 11 samples of sheep and goats between 1 and 2 years, 9 samples of sheep and goats between 2 and 3 years, 8 samples between 3 and 4 years old, and 4 samples of sheep and goats are over 4 years) are positive with a view of shedding of oocyst. There was significant statistical relationship between infection rate and sex P<0.05. There was significant statistical relationship between infection rate and age P<0.05. There was significant statistical relationship between infection rate and seasons of the year P<0.05 and there was no significant statistical relationship between sheep population and goat population in Mahabad city (P>0.05).

   Cryptosporidium is a parasite that can cause diarrhea in sheep. Disease caused by Cryptosporidium is a zoonotic disease. Given its importance, this study carried out to evaluate the Cryptosporidium infection rate in sheep in Noubaran distinct of Saveh County in 2014.  In this cross-sectional study on 266 asymptomatic sheep, fecal samples were collected and transported to the laboratory and condensed. then samples were stained using modified Ziehl-Neelsen technique and examined by the use of an optical microscope.  The prevalence of Cryptosporidium infection in studied samples was 10.5%. The results indicate that the rate of infection in rams was higher than ewes, the rate of infection in less than 1 year old sheep was higher than over 1 year old ones, and the rate of infection in herds with over 100 sheep was higher than herds with less than 100 sheep. Of course, no statistically significant relation was seen between factors such as age, gender and the number of herds with disease (p>0.05) This study showed that Cryptosporidium infection in sheep in this area was noticeable. Meanwhile, as this study has been done on animals without clinical signs, asymptomatic sheep could be a potential source to spread the infection to humans and ultimately the community.
