“…Our findings further showed that the prevalence of G. duodenalis was 4.0% and 4.3% in sheep and goats, respectively. These results are consistent with many previous studies in Iran and elsewhere [2,[32][33][34][35][36][37]. In two previous Iranian studies, the prevalence of G. duodenalis was estimated at 6.2% (12/192) in sheep, and at 5.0% (5/100) in goats in Yazd [29].…”

Gastrointestinal parasites (GIP) are a major cause of disease and production loss in livestock. Some have zoonotic potential, so production animals can be a source of human infections. We describe the prevalence of GIP in domestic mammals in Southeastern Iran. Fresh fecal samples (n = 200) collected from cattle (n = 88), sheep (n = 50), goats (n = 23), camels (n = 30), donkeys (n = 5), horse (n = 1), and dogs (n = 3) were subjected to conventional coprological examination for the detection of protozoan (oo)cysts and helminth ova. Overall, 83% (166/200) of the samples were positive for one or more GIP. Helminths were found in dogs, donkeys, sheep (42%), camels (37%), goats (30%), and cattle (19%), but not in the horse. Protozoa were found in cattle (82%), goats (78%), sheep (60%), and camels (13%), but not in donkeys, dogs, or the horse. Lambs were 3.5 times more likely to be infected by protozoa than sheep (OR = 3.5, 95% CI: 1.05–11.66), whereas sheep were at higher odds of being infected by helminths than lambs (OR = 4.09, 95% CI: 1.06–16.59). This is the first study assessing the prevalence of GIP in domestic mammals in Southeastern Iran.

“…In sheep, assemblage E was identified in 79.5% of positive isolates typed, while assemblage A was identified in 20.5% of faecal samples positive for G. duodenalis. With the exception of one study conducted on sheep in Victoria, which reported a higher prevalence of assemblage A J o u r n a l P r e -p r o o f compared to assemblage E in sheep (Nolan et al, 2010), all other studies reported that assemblage E was the dominant assemblage in Australian sheep (McCarthy et al, 2008;Yang et al, 2009;Sweeny et al, 2011;Yang et al, 2014;Yang et al, 2015). In the present study, all the sheepderived assemblage E sequences were identical and all clustered into a sheep cluster.…”

“…and this will require further studies [159]. The prevalence of the infection in sheep, using quantitative multiplex PCR, in 474 fecal samples from 2 sales yards on 4 occasions and 96 effluent samples, was 6.5% with the zoonotic species C. parvum and C. ubiquitum accounting for 54.2% of the positive samples [160].…”

Background: Cryptosporidiosis is a zoonotic disease caused by the important parasitic diarrheal agent Cryptosporidium spp. Cryptosporidiosis occurs in all classes of animals and man with a rapidly expanding host range and increased importance since the occurrence of human immunodeficiency virus/acquired immunodeficiency syndrome in man. Objectives: To review the global picture of cryptosporidiosis in man and animals with emphasis on prevalence and risk factors. Methods: Current relevant literature on cryptosporidiosis was reviewed. Results: Cryptosporidiosis is widely distributed and the risk factors vary from one region to another with hygiene and immune status as important risk factors. Conclusions: Cryptosporidium spp. associated mortality has not only been reported in immune-compromised patients, but also in immune-competent patients. Yet in many countries not much attention is paid to the control and prevention of this infection in animals and man. The neglect of this disease despite the serious threat it poses to animals, their husbandry, and humans, has led the World Health Organization to list it among globally neglected diseases. To control and prevent this infection more effort needs to be directed at controlling the risk factors of the infection in man and animals.
