Evidence of host-associated populations of Cryptosporidium parvum in Italy.
Recent studies have revealed extensive genetic variation among isolates of Cryptosporidium parvum, an Apicomplexan parasite that causes gastroenteritis in both humans and animals worldwide. The parasite's population structure is influenced by the intensity of transmission, the host-parasite interaction, and husbandry practices. As a result, C. parvum populations can be panmictic, clonal, or eve...
متن کاملIntra-Species Diversity and Panmictic Structure of Cryptosporidium parvum Populations in Cattle Farms in Northern Spain
The intra-herd and intra-host genetic variability of 123 Cryptosporidium parvum isolates was investigated using a multilocus fragment typing approach with eleven variable-number tandem-repeat (VNTR) loci and the GP60 gene. Isolates were collected from intensively farmed diarrheic pre-weaned calves originating from 31 dairy farms in three adjoining regions in northern Spain (País Vasco, Cantabri...
متن کاملComplete development of Cryptosporidium parvum in host cell-free culture.
The present study describes the complete in vitro development of Cryptosporidium parvum (cattle genotype) in RPMI-1640 maintenance medium devoid of host cells. This represents the first report in which Cryptosporidium is shown to multiply, develop and complete its life cycle without the need for host cells. Furthermore, cultivation of Cryptosporidium in diphasic medium consisting of a coagulate...
متن کاملInvolvement of host cell integrin α2 in Cryptosporidium parvum infection.
Cryptosporidium parvum is an opportunistic pathogen in AIDS patients. It is an intracellular but extracytoplasmic parasite residing in a host cell-derived parasitophorous vacuole. It is still poorly understood how this parasite interacts with host cells. We observed that expression of the integrin α2 (ITGA2) gene in host cells was significantly upregulated upon C. parvum infection, and a higher...
متن کاملGenotyping of Coxiella burnetii from domestic ruminants in northern Spain
BACKGROUND Information on the genotypic diversity of Coxiella burnetii isolates from infected domestic ruminants in Spain is limited. The aim of this study was to identify the C. burnetii genotypes infecting livestock in Northern Spain and compare them to other European genotypes. A commercial real-time PCR targeting the IS1111a insertion element was used to detect the presence of C. burnetii D...
