“…Indicated (11) that the peacock in Al Saada Zoo and the Agricultural Center in Diwaniyah was infected with a mixed infection, and the infection with the Cryptosporidium was recorded at a rate of 33.33%. Globally (12) in Tokyo reported a 7.5% infection rate for Yezo deer according to a PCR test for the Cryptosporidium spp.…”

The current study aimed to investigate parasites in some animals located in Al-Mahaweel reserve located north of Babel Governorate in central Iraq during the winter season. In the study, 261 fecal samples were collected from six species of animals, including Dama dama, Gazelle subgutturosa, Gazelle gazelle, and Macaca sp. and two types of birds are ostrich, Struthio camelus, and peacock, Pavo cristatus to investigate Parasitic infections. Entamoeba recorded the highest infection rate of 81%, followed by cryptosporidium spp. with an infection rate of 42%, Isospora sp. 40%, and the lower rate of infection with the Balantidium sp. of 28.57%, Ascaris sp. of 22.85%, Toxocara canis 20%, and one ectoparasite, Hyalomma Marginatum on ostriches with a rate of 16%. This study showed that parasitic infections are widespread in captive animals in the winter season, and they are among the dangerous causes for the health of these animals. Where it is necessary to conduct more studies to examine the mechanism of transmission of parasites among protected animals.

“…Cryptosporidium species, the causative agents of cryptosporidiosis, are the important opportunistic intestinal pathogens that can infect various hosts including cattle and humans (1)(2)(3). The ingestion of contaminated water and foods is the main risk factor for calves and other hosts as well as humans for Cryptosporidium spp.…”

The aim of this study was to compare three diagnostic methods for the diagnosis of cryptosporidiosis and to detect subtypes ofCryptosporidium parvum by sequences analyses of gp60 gene in diarrheic calves in several herds in Konya province located in Central Anatolia Region of Turkey. Fecal samples were collected from a total of 194 pre-weaned calves (n=158, ≤15 days old, and n=36, 15 to 40 days old), with diarrhoea. For comparative diagnosis, all samples were examined by modified Ziehl-Neelsen staining of fecal smears for the presence of oocyst, nested PCR-RFLP of SSU rRNA and TaqMan qPCR for the detection of Cryptosporidium DNA. A total of 92 (47.4%) and 104 (53.6%) out of the examined samples were found positive by microscopic examination and molecular tools, respectively. The diagnostic sensitivity and specificity of microscopic identification were determined as 88.5% and 100.0%, respectively compared to molecular assays. Cryptosporidium parvum was the only detected species in all positive samples by species-specific qPCR and nested PCR-RFLP assays. Species identifications were further confirmed by sequence analyses of the SSU rRNA PCR products. There was no statistically significant difference in C. parvum prevalence between early pre-weaned calves and calves older than 15 days. The sequence analyses of the gp60 gene of C. parvum isolates revealed a one subtype IIaA13G2R1 belonging to zoonotic family IIa in diarrheic calves

Cryptosporidium species infect domestic animals, livestock, and humans. These protozoan parasites are frequently reported as major environmental contaminants in many countries despite their differing climatic, socioeconomic, and demographic factors. This review focuses on the research findings that relate to Cryptosporidium epidemiology, genetic diversity, and associated risk factors relating to animals, contaminated water sources, and humans in Japan. Adequate knowledge of these factors is essential for understanding the economic and public health importance of cryptosporidiosis in Japan so that effective control strategies against it are implemented. Cryptosporidium infections are highly prevalent in animals in Japan. Among the different animal species, cattle infections stand out because of their economic importance and zoonotic potential. Living circumstances in Japan restrain Cryptosporidium transmission between humans, but there is evidence to suggest that animals, especially those in close contact with humans, can be potential sources of human infections. Water sampling studies have provided clues about how environmental contamination with Cryptosporidium oocysts can cause infections in livestock and wild animals. There is some evidence of personto-person transmission of cryptosporidiosis, but only occasionally and under certain circumstances. By identifying the major role played by animals in Cryptosporidium transmission to people in Japan, we highlight the urgent need for disease control against this pathogen.
