“…However, in this study, the infection rate of Cryptosporidium was lower than those in free-living wild birds in Hungary (5.8% 6/103), Brazil (6.6% 16/242), and Spain (8.3% 36/433) [22][23][24]. Other studies have also reported much higher infection rates of Cryptosporidium in wild birds than this study, e.g., in wild captive psittacines in Brazil (10.64% 5/47), Java sparrows (Lonchura oryzivora) in northern China (13.42% 47/350), and North American red-winged blackbirds (Agelaius phoeniceus) (17.1% 12/70), and Canada geese (23.4% 49/209) in Ohio and Illinois [25][26][27][28]. Previous studies recorded Cryptosporidium infection rates in domestic birds of 2.3%-4.86% in Brazil [29][30][31] and 0.82%-8.1% in China [32][33][34][35][36].…”

Cryptosporidium is an important protozoan parasite that can cause gastrointestinal diseases in humans and that also causes respiratory and gastrointestinal diseases in birds. In this study, we investigated the occurrence of Cryptosporidium species in migratory whooper swans in China. Fecal samples (n = 467) from whooper swans were collected from Sanmenxia Swan Lake National Urban Wetland Park, China. The samples were analyzed for Cryptosporidium species and genotypes with PCR along a sequence analysis of the small subunit rRNA. Cryptosporidium was detected in eight of the 467 (1.7%) samples. The analysis of the small subunit rRNA sequence data revealed two zoonotic species (Cryptosporidium parvum and Cryptosporidium andersoni) and one genotype (Cryptosporidium goose genotype II). These are the first data on the positive rate of Cryptosporidium spp. in whooper swans in China, and they suggest that whooper swans can harbor the zoonotic species C. parvum and C. andersoni in China.

“…was detected in 43.95% (80/182) of fecal samples using the centrifugation-sedimentation technique followed by Ziehl-Neelsen staining (Henriksen and Pohlenz, 1981). However, it is important to highlight that molecular techniques have also been used in studies with birds (Sevá et al, 2011;Ferrari et al, 2018;Oliveira et al, 2017). Despite the scarcity of studies on Cryptosporidium spp.…”
