cryptosporidium parvum in cattle, sheep and pigs in galicia (n.w. spain).infection by cryptosporidium parvum has been detected for the first time in cattle and swine in galicia (n.w. spain). the organisms were also found in one of 69 sheep examined. although in most cases the parasite was found in young diarrhoeic animals, its presence in asymptomatic mature cattle and piglets was also detected.19911858293
detection of infectious cryptosporidium parvum oocysts in mussels (mytilus galloprovincialis) and cockles (cerastoderma edule).infective cryptosporidium parvum oocysts were detected in mussels (mytilus galloprovincialis) and cockles (cerastoderma edule) from a shellfish-producing region (gallaecia, northwest spain, bounded by the atlantic ocean) that accounts for the majority of european shellfish production. shellfish were collected from bay sites with different degrees of organic pollution. shellfish harboring c. parvum oocysts were recovered only from areas located near the mouths of rivers with a high density of gra ...200010788352
occurrence of cryptosporidium parvum and giardia duodenalis in healthy adult domestic determine the prevalence and intensity of infection of cryptosporidium spp. and giardia duodenalis in healthy adult domestic ruminants, faecal samples were collected from 379 cattle of between 3 and 13 years old, 446 sheep and 116 goats selected at random from 60 dairy farms and 38 and 20 herds, respectively, in galicia (nw spain). cryptosporidium spp. oocysts were detected in 32 cows (8.4%), 24 sheep (5.3%) and in nine goats (7.7%) from, respectively, 48.3% of the farms and 34.2 and 30.0% of ...200717569991
contribution of treated wastewater to the contamination of recreational river areas with cryptosporidium spp. and giardia duodenalis.samples of the influent and final effluent from 12 wastewater treatment plants from galicia (nw, spain) were analyzed for the presence of cryptosporidium spp. oocysts and giardia duodenalis cysts. all of the plants discharge effluent to a hydrographic basin in which there are numerous recreational areas and fluvial beaches. the samples (25-50 liters) were collected in spring, summer, autumn and winter of 2007. a total of 96 samples were analyzed using techniques included in the us environmental ...200818538816
presence of cryptosporidium spp. and giardia duodenalis through drinking evaluate the presence of cryptosporidium spp. and giardia duodenalis in the influent and final effluent of sixteen drinking water treatment plants located in a hydrographic basin in galicia (nw spain) - in which the principal river is recognised as a site of community importance (sci) - estimate the efficiency of treatment plants in removing these protozoans and determine the species and genotypes of the parasites by means of a molecular assay. all plant samples of influent and final effluent ...200818684490
occurrence of giardia and cryptosporidium in wild birds in galicia (northwest spain).faecal samples were obtained from 433 wild birds being treated in wildlife recovery centres in galicia (northwest spain), between february 2007 and september 2009. the birds belonged to 64 species representing 17 different orders. giardia cysts and cryptosporidium oocysts were detected by an immunofluorescence antibody test and identified at the molecular level by established pcr-sequencing methods. the overall prevalence of giardia was 2·1% and that of cryptosporidium, 8·3%. to our knowledge, t ...201525669618
presence of cryptosporidium scrofarum, c. suis and c. parvum subtypes iiaa16g2r1 and iiaa13g1r1 in eurasian wild boars (sus scrofa).the aim of the present study was to identify the species of cryptosporidium infecting eurasian wild boars (sus scrofa) in galicia (nw, spain). a sampling of 209 wild boars shot in different game preserves was carried out during the hunting season in 2009-2010. all samples were examined for cryptosporidium infection, using both immunological and molecular tools. cryptosporidium oocysts in faecal samples were identified using a direct immunofluorescence technique with monoclonal antibodies (dfa). ...201323643454
genotype and subtype analysis of cryptosporidium isolates from calves and lambs in galicia (nw spain).faecal specimens from diarrhoeic pre-weaned calves (n=61) and lambs (n=127) collected over a 1-year period (2008-2009) at 27 cattle and 28 sheep farms in galicia (nw spain) were examined for the presence of cryptosporidium oocysts and positive specimens were selected for molecular examination. overall, 30 calves (49.2%) and 39 lambs (30.7%) tested positive for cryptosporidium by microscopy. pcr products of the ssu rrna locus were obtained for 27 cryptosporidium positive calf isolates and 23 lamb ...201020380767
cryptosporidium contamination in harvesting areas of bivalve molluscs.cryptosporidium contamination was evaluated in areas in galicia (northwestern spain) where bivalve molluscs are harvested. galicia is the main mussel-producing region in europe. data were collected on water contamination of effluents that are discharged into these areas. cryptosporidium spp. were detected by immunofluorescence microscopy and molecular methods in 71% of the river water samples (n = 7), 64% of raw sewage samples (n = 11), 50% of effluents from wastewater treatment plants (n = 16), ...200616416917
prevalence of and risk factors involved in the spread of neonatal bovine cryptosporidiosis in galicia (nw spain).an epidemiological study was carried out on farms in galicia (nw spain) to investigate the prevalence of and the risk factors associated with the spread of infection by cryptosporidium parvum in calves of less than 3 weeks of age. a total of 22 cattle farms (10 beef herds and 12 dairy herds) were visited once every 21 days between january and december 2000. a faecal sample was collected directly from the rectum of each of the 844 calves born during the study period. each sample was studied macro ...200211992706
