Anthelmintic effect of Pterogyne nitens (Fabaceae) on eggs and larvae of Haemonchus contortus: analyses of structure-activity relationships based on phenolic compounds. Author(s): LIMA, C. S.; PEREIRA, M. H.; ALEMÁN GAINZA, Y.; HOSTE, H.; REGASINI, L. O.; CHAGAS, A. C. de S. Due to high prevalence and large pathogenicity, Haemonchus contortus is the main gastrointestinal nematode in tropical and subtropical regions. This species is responsible for severe economic losses t... ... Repository: BDPA Publication year: 2021
Biological activity of cinnamaldehyde, citronellal, geraniol and anacardic acid on Haemonchus contortus isolates susceptible and resistant to synthetic anthelmintics. Author(s): FROTA, G. A.; SANTOS, V. O. dos; RODRIGUES, J. F. V.; OLIVEIRA, B. R.; ALBUQUERQUE, L. B.; VASCONCELOS, F. R. C. de; SILVA, A. C.; TEIXEIRA, M.; BRITO, E. S. de; SANTOS, J. M. L. dos; VIEIRA, L. da S.; MONTEIRO, J. P. Abstract: Parasitism by gastrointestinal nematodes is a challenge for small ruminant farming worldwide. It causes productive and economic losses, especially due to parasite resistance to conventional... ... Repository: BDPA Publication year: 2023
Chemical composition and anthelmintic activity in vitro of the essential oil of Mentha piperita: preliminary data. Author(s): MESQUITA, R. J. M.; MONTEIRO, J. P.; CATUNDA, F. E. A.; TEIXEIRA, M. Abstract: Research towards plant compounds with activity against worm parasites has been carried out for a number of decades; however it is especially important now when drench resistance has compromi... ...
