ABSTRACT To provide information on the transmission dynamics of cryptosporidial infections in domestic small ruminants and potential role sheep goats as a source for human cryptosporidiosis, Cryptosporidium -positive isolates from 137 diarrheic lambs 17 goat kids younger than 21 days age were examined by using genotyping subtyping techniques. Fecal specimens collected between 2004 2006 71 7 farms distributed throughout Aragón (northeastern Spain). parvum was only species identified...
Cryptosporidium spp. infections in calves cause serious economic losses livestock and pose an important zoonotic risk. The aim of this study was to investigate the prevalence cattle on island Gran Canaria. Faecal samples were collected from adult a total 15 farms, questionnaire survey conducted farmers. presence oocysts faeces determined by microscopy, showing infection rates 45.9% 4.1% adults, with positive correlation faecal scores infected animals (p < 0.0001). Samples amplified PCR...
Limited molecular data exist on the prevalence and subtype distribution of Blastocystis spp., most prevalent parasite in human animal feces worldwide. A total 44 different subtypes (STs) are currently recognized based sequence small subunit ribosomal RNA (SSU-rRNA) gene. This is a study spp. hospitalized patients with gastrointestinal symptoms northern Spain. We analyzed 173 Blastocystis-positive by using nested PCR for detection, identification, phylogenetic analyses, genetic diversity...
SUMMARY Faecal specimens from 287 diarrhoeic calves younger than 21 days, collected over a 2-year period (2006–2007) 82 dairy cattle farms in 14 provinces across the north of Spain, were examined for presence Cryptosporidium oocysts. Overall, 63 (76·8%) and 166 (57·8%) tested positive by microscopy. In order to elucidate genetic diversity, selected 149 originating 61 genotyping subtyping techniques. parvum was only species identified PCR-RFLP SSU rDNA all isolates sequencing subset 50...
This study describes a novel immunization strategy against avian coccidiosis using exosomes derived from Eimeria parasite antigen (Ag)-loaded dendritic cells (DCs). Chicken intestinal DCs were isolated and pulsed in vitro with mixture of sporozoite-extracted Ags tenella, E. maxima, acervulina, the cell-derived isolated. Chickens nonimmunized or immunized intramuscularly subsequently noninfected coinfected acervulina oocysts. Immune parameters compared among nonimmunized/noninfected,...
Blastocystis sp. is known to be the most prevalent parasite in fecal samples of humans worldwide. In present report, a case–control study (1:9.89 (≈10)) was performed, by analyzing data from 3682 patients who attended public hospital northern area Spain showing gastrointestinal symptoms. Diagnosis performed human means optical microscopy. The prevalence with symptoms 9.18% (338/3682). Most sp.-infected tested negative for protozoa and helminths, were underweight foreign-born (26.4%), mainly...
Parasites are concerning food-borne pathogens. Some of them currently not being routinely controlled in food, probably because their burden on public health is underestimated and the relative importance different transmission routes completely known. Parasitic incidences could be avoided if preventive technologies were applied during food processing. Effective inactivation treatments based heat or freezing, but side effects collide head-on with current consumer trends new culinary habits....
The aim of this study was to analyse and characterise Cryptosporidium spp. in sheep goats Gran Canaria (Spain) identify the risks economic factors related disease. During sampling, a semi-structured survey conducted with farmers, faecal samples were collected from lambs, goat kids, sheep, adult total 30 farms. Adult examined microscopically for presence oocysts, only three positive being found one goats. PCR SSU rRNA gene performed on all juvenile samples, lambs (8.3%), (6.9%), kids (23.3%),...
Abstract. The abundance, seasonal activity patterns and development rates of the tick Ixodes ricinus (L.) (Acari: Ixodidae), as well microclimate features site study, are described for a 9‐year‐long study (1994–2002) in north‐central Spain. According to drag captures, larvae had unimodal pattern, with maximum observed around July–August, whereas nymphs displayed bimodal pattern (May–June August–September) strong dominance spring activity. An inversion this larger autumn peak, was years humid...
SUMMARY Faecal specimens from diarrhoeic pre-weaned calves ( n =61) and lambs =127) collected over a 1-year period (2008–2009) at 27 cattle 28 sheep farms in Galicia (NW Spain) were examined for the presence of Cryptosporidium oocysts positive selected molecular examination. Overall, 30 (49·2%) 39 (30·7%) tested by microscopy. PCR products SSU rRNA locus obtained calf isolates 23 lamb isolates. Restriction analyses generated profiles C. parvum all except 9 5 that yielded banding patterns...
Although IL17A is associated with the immunological control of various infectious diseases, its role in host response to Eimeria infections not well understood. In an effort better dissect host-pathogen interactions avian coccidiosis, a neutralizing antibody (Ab) chicken was used counteract bioactivity vivo. Chickens infected tenella and treated intravenously Ab, exhibited reduced intracellular schizont merozoite development, diminished lesion score, compared untreated controls....
Species A rotavirus (RVA) is a major viral pathogen causing diarrhea in suckling piglets. Studies on its genetic heterogeneity have implications for vaccine efficacy the field. In this study, fecal samples (n = 866) from diarrheic piglets younger than 28 days were analyzed over two-year period (2018-2019). Samples submitted 426 farms located 36 provinces throughout Spain and tested using real-time PCR (qPCR) reverse transcription (RT-qPCR) five enteric pathogens. The individual prevalence...
