Occurrence and genotypes of Giardia isolated from lambs in Spain
2009
Three hundred and eighty six faecal specimens were randomly collected from 1- to 3-month-old lambs from 16 farms in Spain to investigate the presence of different genotypes of Giardia duodenalis. Individual specimens were examined by IFA (Immunofluorescence assay) and beta-giardin PCR polymerase chain reaction. Cysts of G. duodenalis were shed by lambs in every flock analyzed, showing a prevalence by farms of 100%. The average prevalence of G. duodenalis for the 386 specimens was 42%, ranging from 8.3 to 80% depending on the farm. beta-giardin PCR positive samples were sequenced to determine the genotypes present at each farm and seven new subtypes of beta-giardin Assemblage E are reported …
Biological Profiling of Semisynthetic C19-Functionalized Ferruginol and Sugiol Analogues
2021
[EN] The abietane-type diterpenoids are significant bioactive compounds exhibiting a varied range of pharmacological properties. In this study, the first synthesis and biological investigation of the new abietane-diterpenoid (+)-4-epi-liquiditerpenoid acid (8a) together with several of its analogs are reported. The compounds were generated from the readily available methyl callitrisate (7), which was obtained from callitrisic acid present in Moroccan Sandarac resin. A biological evaluation was conducted to determine the effects of the different functional groups present in these molecules, providing basic structure-activity relationship (SAR) elements. In particular, the ferruginol and sugi…
