“…Avian genotype II was first described in turkey and was reported in parrot in the same year [14, 16]. Afterward, avian genotype II was found in ostriches [17]. Recently, chickens have also appeared to be a new host for avian genotype II.…”

“…Traditionally, three different species of Cryptosporidium ( C. baileyi , C. meleagridis , and C. galli ) were considered to be the major species in birds [4, 6, 17, 20, 23, 30]. Recently, more than 11 novel genotypes have been described which are genetically different from the above three species by means of molecular analysis, including avian genotypes (I–V), goose genotypes (I–IV), the Eurasian woodcock genotype and the black duck genotype [1, 9, 14–17, 20, 31]. C. meleagridis , C. parvum , and C. hominis carried by poultry may infect human beings through the oocysts in contaminated water or vegetables eaten uncooked [1, 13, 20, 31, 32].…”

Cryptosporidium is one of the most important parasites in poultry, and this pathogen can infect more than 30 avian species. The present study investigated the infection rate of Cryptosporidium among broiler chicken flocks. A total of 385 fecal samples from broiler chickens in 7 regions of Zhejiang Province collected from November 2010 to January 2012 were examined by microscopy. Thirty-eight (10%) samples were positive for Cryptosporidium infection, and 3 genotypes (Cryptosporidium baileyi, Cryptosporidium meleagridis, and avian genotype II) were identified by PCR and sequencing. A phylogenetic tree of the isolates was analyzed. These results suggest that cryptosporidiosis is widespread in poultry in Zhejiang Province, and is a potential threat to public health as well as the economy. This is the first report about the infection rate and molecular characterization of Cryptosporidium in broiler chickens in Zhejiang.

“…The avian genotype II has been described in ostriches and in several Psittaciformes species (SANTOS et al, 2005;MEIRELES et al, 2006;NG et al, 2006;SEVÁ et al, 2011;NGUYEN et al, 2013). Although Wang et al (2014b) reported the presence of avian genotype II in 0.78% (3/385) of fecal samples from chickens in China, Meireles et al (2006) did not observe infection among chickens that were experimentally infected with avian genotype II and screened for Cryptosporidium infection using cytology, histology and oocyst screening in feces.…”

Cryptosporidiosis is one of the main protozoan infections in birds. It manifests as either a respiratory or a digestive illness, and it affects a very large number of avian species across several continents. The aim of this review is to report on the main results of studies on cryptosporidiosis among birds and the importance of these results to veterinary medicine and public health.Keywords: Cryptosporidium spp., wild birds, poultry. ResumoA criptosporidiose constitui-se em uma das principais infecções por protozoários em aves, manifestando-se como enfermidade respiratória ou digestiva, em dezenas de espécies aviárias, em vários continentes. O objetivo desse trabalho foi relatar, por meio de revisão de literatura, os principais resultados de estudos sobre criptosporidiose em aves e sua importância para a medicina veterinária e saúde pública.Palavras-chave: Cryptosporidium spp., aves selvagens, aves domésticas.

“…Furthermore, several Cryptosporidium genotypes have been described in various bird species, including genotype I (Ng et al, 2006;Nakamura et al, 2009), genotype II (Santos et al, 2005;Meireles et al, 2006;Ng et al, 2006;Nakamura et al, 2009, Sevá et al, 2011Nguyen et al, 2013), genotype III (Ng et al, 2006;Nakamura et al, 2009;Qi et al, 2011), genotype IV (Ng et al, 2006) and genotype V Qi et al, 2011). Additional genotypes have also been identified in geese (Jellison et al, http://dx.doi.org/10.1016(Jellison et al, http://dx.doi.org/10.…”
