“…Because pig raising in China is an important agricultural activity, and because of high potential for pig to human transmission, it is relevant to investigate the epidemiology of Cryptosporidium in these animals. Results from the current study showed that prevalence in pigs was similar as found in Korean (10.5%) (Yu and Seo, 2004) and Canada (11%) (Olson et al., 1997), but different from that reported from in Spain (21.9%) (Quilez et al., 1996), the United States (5.3%) (Sanford, 1987) and Germany (1.4%) (Wieler et al., 2001). Many factors may contribute to the different rates, including climate, farm practices and the porcine breeds in different countries.…”

Faecal samples from 1488 pigs were collected from six pig farms in Jiangsu province and Shanghai city, eastern China, stained by the modified acid-fast staining technique (MAFS) and observed by light and phase contrast microscopy to identify Cryptosporidium oocysts. A total of 178 (12%) positive animals were detected. Three randomly selected MAFS-positive samples from each farm were further analysed by reverse-transcription polymerase chain reaction (RT-PCR) using primers designed to amplify DNA fragments from the small subunit ribosomal RNA (SSU rRNA) gene. PCR products from two positive samples were sequenced. Phylogenetic analysis and a distances matrix generated from these sequences showed that the isolates belonged to the species C. parvum, and were most similar to the C. parvum'mouse' genotype. The identification of this C. parvum genotype in pigs has not been reported previously. These findings are discussed in the context of the epidemiology of Cryptosporidium on pig farms.

“…This high prevalence in our study may be due to irregular or limited parasitic infection control program. While, lower prevalence of Cryptosporidium infection in goats may be attributed to the environmental and ecological factors where relative low humidity and short period of rainfall may be recorded (Yu and Seo, 2004). Results revealed highest percent prevalence during summer season (22%), followed by autumn (14%), spring (12%) and lowest was (7%) in winter.…”

“…Inwazje C. parvum u pozostałych gatunków zwierząt gospodarskich i towarzyszących Wprowadzenie metod molekularnych do diagnostyki parazytologicznej pozwoliło na identyfikację C. parvum również u innych gatunków zwierząt niż przeżuwacze. Zarażenia C. parvum w stadach trzody chlewnej są na ogół rzadkie (70,87,107,115), z ekstensywnością inwazji na poziomie stada nie przekraczającą 1,4% (111). Poza Europą wynosi ona od 5,4% (Stany Zjednoczone) do 33,2% w Japonii (5, 40).…”

Cryptosporidium parvum is a zoonotic protozoan parasite occurring in a wide range of hosts. Invasions caused by this parasite have been reported in humans and in many animal species including birds. Despite its worldwide prevalence, infections have usually generated considerable losses in the livestock industry, mostly affecting calves, lambs and goat kids. It has previously been shown that ruminants are a major reservoir of zoonotic Cryptosporidium parvum and contact with an infected animal can lead to human infection. The application of molecular methods for parasitological diagnostics has increased our knowledge on the parasite hosts and its prevalence in humans and animals. They also confirmed their usefulness during epidemiological investigations and in surveillance studies of human and animal cryptosporidiosis. In this review the current state of knowledge concerning the importance of Cryptosporidium parvum invasions in farm and wild animals was presented.
