“…However, most reports on the prevalence in chickens were published in the 1980s and 1990s, with infection rates ranging from 4.5 to 50% depending on the location and the methods used in detection (de Graaf et al, 1999). In contrast, in the past 10 years there have been only about six reports (Trampel et al, 2000;Kimura et al, 2004;Huber et al, 2007;Soltane et al, 2007;Shemshadi et al, 2010;Smith et al, 2010). Likewise, there are only a few reports (about seven) concerning Cryptosporidium infections in ducks (Mason, 1986;Richter et al, 1994;O'Donoghue, 1995;Morgan et al, 2001;Kuhn et al, 2002;Huber et al, 2007;Amer et al, 2010).…”

“…In European countries such as Scotland and Greece, the infection rates in broilers were 18.7% (26/139) and 24.3% (17/70), respectively (Randall, 1982;Papadopoulou et al, 1988). In Africa, 24% (54/225) and 4.5% (9/200) prevalence rates were reported in Morocco and Tunisia, respectively (Kichou et al, 1996;Soltane et al, 2007). In Japan and Iran, rates of 33.3% (4/12) and 23.8% (57/152) were observed, respectively, in broiler chickens (Itakura et al, 1984;Shemshadi et al, 2010).…”

Few data are available on the molecular characterization of Cryptosporidium spp. in chickens and ducks in China. In this study, 2579 faecal samples from 46 chicken farms and eight Pekin duck farms in 21 prefectures in Henan Province were examined. The overall infection rate of Cryptosporidium was 10.6% (163/1542) in layer chickens (10 out of 17 farms), 3.4% (16/473) in broilers (five out of 29 farms), and 16.3% (92/564) in Pekin ducks (four out of eight farms), respectively. The highest infection rates were observed in 31-day-old to 60-day-old layer chickens (24.6%) and 11-day-old to 30-day-old Pekin ducks (40.3%). The season of highest prevalence in chickens was spring (15.6%) and the lowest was winter (P B0.01). One hundred and eightyseven Cryptosporidium-positive samples were analysed by polymerase chain reaction (PCR)Árestriction fragment length polymorphism analysis of the small subunit rRNA gene, and 55 were further analysed by DNA sequencing of the PCR products. Two Cryptosporidium species were identified: Cryptosporidium baileyi (184/187) on 15 chicken farms and four duck farms, and Cryptosporidium meleagridis (3/187) on three layer chicken farms. C. baileyi was the predominant Cryptosporidium species, found in all age groups of chickens and all Cryptosporidium-positive ducks examined, whereas C. meleagridis was only identified in 31-day-old to 120-day-old layer chickens. Considering the large size of the chicken industry and the close contact between chickens and humans, and that C. meleagridis is the third most common Cryptosporidium parasite in humans, then C. meleagridis could potentially become an emerging zoonosis in some areas in China.

“…Like C. parvum, C. meleagridis appears to have a large host range and has been described from a wide range of avian species including turkeys, parrots, chickens, cockatiels and a red-legged partridge (O'Donoghue, 1995, Morgan, et al, 2000b, Darabus and Olariu, 2003, Abe and Iseki, 2004Huber et al, 2007;Pagès-Manté et al, 2007;Soltane et al, 2007). Experimental transmission studies have shown that C. meleagridis can infect broiler chickens, ducks, turkeys, calves, pigs, rabbits, rats, mice (O'Donoghue, 1995, Darabus and Olariu, 2003, Huang, et al, 2003.…”

ResumoEstudos referentes á criptosporidiose são essenciais, devido sua relevância em saúde pública e por sua patogenicidade em animais de produção e de companhia. Nos últimos 20 anos, houve uma rápida expansão das pesquisas envolvendo o gênero Cryptosporidium, em grande parte relacionada a estudos moleculares, propiciando a descrição de várias espécies, genótipos e subtipos do parasito. A caracterização molecular de isolados de diferentes origens (animal, humana e ambiental) tem sido amplamente usada com o intuito de investigar o potencial zoonótico deste protozoário. As formas de transmissão documentadas são de animais para o ser humano, de pessoa para pessoa, por meio de ingestão ou do uso de água destinada a lazer contaminada direta ou indiretamente com oocistos esporulados. A elevada taxa de animais naturalmente infectados e a susceptibilidade ao protozoário justificam a importância de se atentar para a ocorrência desta enfermidade. Assim, são demonstrados aspectos epidemiológicos desta zoonose em animais domésticos. Palavras-chave: Cryptosporidium spp., ruminantes, equinos, caninos, felinos AbstractStudies related cryptosporidiosis will be essential, due to its relevance in public health and pathogenicity in pets and production animals. Over the past 20 years, there has been a rapid expansion of research involving the Cryptosporidium genus, largely related to molecular studies, providing a description of
