Cryptosporidium Taxonomy: Recent Advances and Implications for Public Health (Review) [PDF]

, 2004
There has been an explosion of descriptions of new species of Cryptosporidium during the last two decades. This has been accompanied by confusion regarding the criteria for species designation, largely because of the lack of distinct morphologic ...

Identification of novel cryptosporidium genotypes from the Czech Republic [PDF]

, 2003
Isolates of Cryptosporidium from the Czech Republic were characterized from a variety of different hosts using sequence and phylogenetic analysis of the 18S ribosomal DNA and the heat-shock (HSP-70) gene.

The Cryptosporidium "mouse" genotype is conserved across geographic areas. [PDF]

, 1999
A 298-bp region of the Cryptosporidium parvum 18S rRNA gene and a 390-bp region of the acetyl coenzyme A synthetase gene were sequenced for a range of Cryptosporidium isolates from wild house mice (Mus domesticus), a bat (Myotus adversus), and cattle ...

Sheep may not be an important zoonotic reservoir for Cryptosporidium and Giardia parasites [PDF]

, 2005
Little is known of the prevalence of Cryptosporidium and Giardia parasites in sheep and the genotypes that they harbor, although potentially sheep may contribute significantly to contamination of watersheds.

Therapeutic Effects of Matricaria chamomilla Extract in an Immunosuppressed Mouse Model of Cryptosporidiosis

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
Chamomile (Matricaria chamomilla) extract significantly reduced oocyst shedding and intestinal lesions in immunosuppressed mice infected with Cryptosporidium parvum, while enhancing antioxidant defences (GPx, TAC). These findings suggest chamomile as a promising phytotherapeutic agent for cryptosporidiosis. ABSTRACT Background Cryptosporidiosis, caused

Comparative analysis reveals conservation in genome organization among intestinal Cryptosporidium species and sequence divergence in potential secreted pathogenesis determinants among major human-infecting species

BMC Genomics, 2019
Background Cryptosporidiosis is a major cause of gastrointestinal diseases in humans and other vertebrates. Previous analyses of invasion-related proteins revealed that Cryptosporidium parvum, Cryptosporidium hominis, and Cryptosporidium ubiquitum mainly

Simplified methods for obtaining purified oocysts from mice and for growing Cryptosporidium parvum in vitro [PDF]

, 1996
Seven- to 8-day-old Arc/Swiss mice were infected with 100,000-120,000 Cryptosporidium parvum oocysts. At 8 days postinfection (PI) the jejunum, ileum, cecum, colon, and rectum were removed.

Gastrointestinal Parasites of Domestic Ducks (Anas platyrhynchos domesticus) in Kathmandu, Nepal

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
Gastrointestinal parasites in ducks raised on smallholder farms in Kathmandu, Nepal, are investigated using copromicroscopic examination. A diverse range of protozoa and helminth parasites are detected including the first records of Entamoeba spp., Cryptosporidium sp. and Tyzzeria sp. in ducks in Nepal.

Occurrence of Cryptosporidium spp. and Cystoisospora belli among adult patients with diarrhoea in Maputo, Mozambique

Heliyon, 2018
Infections with Cryptosporidium spp. and Cystoisospora belli are important causes of diarrhoea in HIV patients. Nevertheless, information concerning these two parasites is scarce in many African countries, including Mozambique.
