Despite the overall progress of sheep farming in Brazil, infections with the gastrointestinal parasite Haemonchus contortus represent one the most important problems in sheep production, aggravated by... ... |
Author(s): KATIKI, L. M.; FERREIRA, J. F. S.; ZAJAC, A. M.; MASLER, C.; LINDSAY, D. S.; CHAGAS, A. C. de S.; AMARANTE, A. F. T. The most challenging obstacles to testing products for their anthelmintic activity are: (1) establishing a suitable nematode in vitro assay that can evaluate potential product use against a parasitic... ... |
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... ... |
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... ... |
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... ... |
Author(s): ALEMÁN GAINZA, Y.; FANTATTO, R. R.; NICIURA, S. C. M.; CHAGAS, A. C. de S. The control of gastrointestinal nematodes of small ruminants has been carried out through intense and indiscriminate use of anthelmintics. |
Author(s): BASSETTO, C. C.; CHOCOBAR, M. L. E.; GAINZA, Y. A.; SANTOS, L. A. L.; BELLO, H. J. S.; SILVA, N. M. M.; AMARANTE, A. F. T.; CHAGAS, A. C. de S. A novel larval development test (LDT) named RESISTA-Test© was developed to detect anthelmintic resistance using a 96-well culture plate. |
