“…Although most species predominantly infect the intestine, there is a distinct group of gastric cryptosporidia consisting of C. muris in rodents (Tyzzer, 1907(Tyzzer, , 1910, C. serpentis in reptiles (Levine, 1980), C. (muris) andersoni in ruminants (Lindsay et al, 2000), C. galli in birds (Pavlásek, 1999;Morgan et al, 2001). Cryptosporidium muris was described by Tyzzer in 1907 in gastric glands of mice and was later found in other rodents (Iseki, 1986;Pavlá sek and Lávicka, 1995;Chalmers et al, 1997;Torres et al, 2000) and a rock hyrax (Procavia capensis) (Anderson, 1991). All natural rodent hosts of C. muris belong to the families Muridae and Cricetidae.…”

“…The infection rate with C. parvum in cattle under one month of age was high in the world, as shown in previous reports [12,14], and secondly, that, C. muris oocysts were detected in the fecal samples of adult cattle raised in the public farms situated in the upstream of all rivers under research. In view of these results, it is likely that C. parvum oocysts may originate from private farms.…”

“…To our knowledge, our data first showed the seasonal changes in the density C. parvum oocyst detected in water samples from the rivers in Hokkaido. Recent epidemiological reports on C. parvum, showed that oocysts were detected in polluted farms of many foreign countries in [12,14]. Oocysts were not consistently detected in river water all the year round.…”

ABSTRACT. An epidemiological study was carried out in natural water supplies of Hokkaido, one of the largest dairy prefectures in Japan. To investigate the prevalence of Cryptosporidium parvum (C. parvum) oocysts water samples were collected from three rivers in the eastern area of Hokkaido from August 1999 to October 2001, and C. parvum oocysts were collected and purified by the ferric sulfate flocculation method. The oocysts were detected using the immunofluorescent assay test (IFAT) and 4', 6-diamidino-2-phenylindole (DA PI) staining. The seasonal change in the number of oocysts detected was observed. Oocysts increased in numbers from the late summer to the early autumn (from August to November), thereafter, they exhibited a trend to decrease until December, when no oocysts could be detected. The maximum number of oocysts detected in the three rivers was 3.50, 5.00 and 3.33 oocysts/ l, respectively. The oocyst density in river water changed in relation to the season in 1999, 2000 and 2001. This report first cleared up the seasonal changes in C. parvum oocysts number in river water. KEY WORDS: Cryptosporidium parvum oocyst, river water, seasonal change.

“…For instance, some studies showed that the prevalence of cryptosporidiosis in calves and cattle was higher in winter (Garber et al 1994;Mohammed et al 1999). According to Bull et al (1998) and Torres et al (2000) reports in wild animals, the prevalence of cryptosporidiosis was not age depended. On the other hands, in Iran, some studies found significant relationship among Cryptosporidium infection and age (Gharekhani et al 2014;Heidarnegadi et al 2012).…”

Cryptosporidiosis is one of the important zoonotic diseases caused by an intracellular protozoan parasite called Cryptosporidium. This study aimed to investigate the prevalence of Cryptosporidium spp. infection on 1,115 ruminants, cattle, sheep and goats, in Lorestan province, Iran. Using formol-ether concentration technique and modified Ziehl-Neelsen staining method afterwards, the overall prevalence of Cryptosporidium spp. infection in ruminants of Lorestan province was 7.17 %. Prevalence of infection was 9.07 % (39 of 430), 5.80 % (20 of 345) and 6.18 % (21 of 340) for cattle, sheep and goats respectively. There was no significant difference between contamination of all examined animals and different geographical and climatic situations (P [ 0.05) and diarrhea was not directly associated with Cryptosporidium infection (P [ 0.05). In conclusion, the prevalence of cryptosporidiosis in Lorestan province was relatively low, but it should be noticed that this opportunistic parasite is zoonosis and also can make epidemics in ruminants as well as human population in suitable conditions.
