During an experimental infection of sheep with Fasciola hepatica or F. gigantica, MM3-SERO and MM3-COPRO ELISA tests were applied to compare the kinetics of antibody production and coproantigen release between the 2nd and 32nd week post-infection (wpi). The Kato-Katz technique was used to measure the kinetics of egg shedding by both Fasciola species (eggs(More)
This study was conducted to determine: (1) the associations between anti-Fasciola hepatica antibody levels in milk and some productive and reproductive parameters in dairy cattle, and (2) the threshold antibody level associated with loss of productivity, at both herd and individual level. Anti-F. hepatica antibodies were analysed by MM3-SERO ELISA in milk(More)
Fascioliasis is a re-emerging parasitosis produced by liver flukes of the genus Fasciola. In this study we used protein fingerprinting (PMF) and MS/MS analysis to investigate the Fasciola secretory antigens that are recognized by mAb MM3. The results showed that mAb MM3 binds to several Fasciola cathepsins L1 and L2, but also co-purifies a Kunitz-type(More)
We carried out a field evaluation of the MM3-SERO ELISA for the diagnosis of Fasciola hepatica infection, by analysing serum and milk samples from individual cows and samples from bulk milk tanks. The diagnostic performance of the assay was assessed with serum samples from all 257 cows in eight fluke-free herds, and 240 cows with natural fasciolosis(More)
This work describes the presence of high-affinity iron uptake systems in Vibrio anguillarum serotype O3 strains (subgroups A and B), isolated from diseased fish and environmental samples, as well as the presumptive effect of iron on their virulence. All strains demonstrated an ability to grow under iron-limiting conditions, production of catechol-type(More)
In this study, we evaluate the MM3-COPRO method for detection of Fasciola coproantigens in human fecal samples, and the usefulness of a new preservative/diluent, CoproGuard, developed for preservation of Fasciola coproantigens. The MM3-COPRO assay was evaluated with 213 samples from healthy patients, 30 Fasciola positive fecal samples (according to the(More)
Infections caused by human parasites (HPs) affect the poorest 500 million people worldwide but chemotherapy has become expensive, toxic, and/or less effective due to drug resistance. On the other hand, many 3D structures in Protein Data Bank (PDB) remain without function annotation. We need theoretical models to quickly predict biologically relevant(More)
There are many drugs described with very different affinity to a large number of receptors. In this work, we selected Drug-Target pairs (DTPs/nDTPs) of drugs with high affinity/non-affinity for different targets like proteins. Quantitative Structure-Activity Relationships (QSAR) models become a very useful tool in this context to substantially reduce time(More)
BACKGROUND Human fasciolosis is a re-emerging disease worldwide and is caused by species of the genus Fasciola (F. hepatica and F. gigantica). Human fasciolosis can be diagnosed by classical coprological techniques, such as the Kato-Katz test, to reveal parasite eggs in faeces. However, although 100% specific, these methods are generally not adequate for(More)
Blood-feeding parasites have developed biochemical mechanisms to control heme intake and detoxification. Here we show that a major antigen secreted by Fasciola hepatica, previously reported as MF6p, of unknown function (gb|CCA61804.1), and as FhHDM-1, considered to be a helminth defense molecule belonging to the family of cathelicidin-like proteins(More)
