“…andersoni is also a major species detected in cattle, especially post-weaned or adults [24]. There are several studies on C. andersoni detected in cattle in Japan [2,11,14,16,17,20,26]. Here, we did not detect this species, perhaps because we only sampled from calves.…”

ABSTRACT. Cattle are major hosts of Cryptosporidium. Cryptosporidiosis in neonatal calves is associated with retarded growth, weight loss and calf mortality, and zoonotic infections in humans. Fecal samples were collected from calves in Ishikari District, Hokkaido, Japan and examined by PCR and sequence analyses. Among the 107 fecal samples collected in May and June 2012, 25 (23%) were positive for Cryptosporidium, including 8 samples (7%) having C. parvum, 10 (9%) having C. bovis and 7 (7%) having C. ryanae. This is first time C. ryanae has been detected in Hokkaido. Furthermore, it is the first detection of C. ryanae from pre-weaned calves in Japan. Microscopic observation with the flotation method is powerful and traditional tool for screening for Cryptosporidium species, but it sometimes leads to low detection of Cryptosporidium with low oocyst shedding intensity. If calves with or without diarrhea are examined using the molecular diagnostic tools, C. bovis and C. ryanae might be detected in other areas of Japan including Hokkaido. Here, the zoonotic species, C. parvum, was also observed. Therefore, calves can be potential sources of cryptosporidial infections for humans and other animals. The detection of C. parvum was statistically correlated with diarrhea in calves.

“…Knowledge about the C. andersoni Kawatabi strain is mainly based on the morphology of its oocysts, the sequences of its 18S rRNA and other genes, and its infectivity to mice, all of which make it dissimilar to C. andersoni isolates from cattle in other countries. This strain appears as the following two forms: type A (which is identical to the C. andersoni Kawatabi strain reported previously) and type B (a novel genotype, with a thymine nucleotide insertion in the 18S rRNA gene not present in type A), which has wide-spread transmission among cattle in Japan [ 55 , 102 , 115 ]. The infectivity of this strain has been studied in both immunocompetent and immunodeficient mouse models [ 100 , 116 ], where knowledge about the minimum number of oocysts needed to reliably establish the infection was gained, thereby providing a mouse model for further investigations.…”

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.

“…Perbedaan prevalensi yang didapat salah satunya karena disebabkan oleh sistem pemeliharaan, suhu dan kelembaban asal bibit sapi yang dijual di Pasar Hewan Beringkit. Hal ini sesuai dengan pernyataan yang dinyatakan oleh (Matsubayashi et al, 2009) dan (Putigani et al, 2010) bahwa perbedaan prevalensi dapat disebabkan oleh adanya perbedaan umur hewan, jenis kelamin, imunitas hewan, sanitasi, pencemaran parasit, sistem pemeliharaan, kepadatan populasi, dan kondisi wilayah. Pada penelitian ini sampel yang diambil dari pasar hewan beringkit rata-rata pemeliharaannya hampir sama dan jumlah sampel yang diambil pada penelitian ini tidak merata.…”

Bali cattle are one of the indigenous cattle breeds in Indonesia that are the direct result of domestication from wild bulls. Gastrointestinal protozoan infection is still a factor that often disturbs the health of bali cattle. This study aimed to determine the prevalence and intensity of gastrointestinal protozoa infection in bali calves breeds in Beringkit Animal Market, Badung Regency. The examination was conducted using the floating method, with fecal samples from 100 bali cattle seedlings and the Mc Master method to determine protozoan infection. The results found 41% of the samples were infected with gastrointestinal protozoa. Based on gender, the prevalence of gastrointestinal protozoa infection in male bali calves was 41.1% and in female bali calves was 40.9%. The types of gastrointestinal protozoa found were Eimeria sp, and Balantidium sp. The average infection intensity of Eimeria sp, 36% with an infection intensity of 622.5 ± 2359.21 oocysts/gram of feces, and Balantidium sp, 17% with an infection intensity of 58.82 ± 75.99 cysts/gram of feces. The prevalence in this study was moderate. Male and female cattle have the same chance of being infected with gastrointestinal protozoa. The average infection intensity of Eimeria sp, and Balantidium sp, both protozoa were mild. It is recommended to improve environmental sanitation around bali breeding calves, routine feces cleaning and hygienic feeding methods
