Anthelmintic efficacy in sheep and goats under different management and deworming systems in the region of Lisbon and Tagus Valley, PortugalGastrointestinal parasitesSmall ruminantsAnthelmintic efficacyFECRTLisbon and Tagus ValleyPortugalResearch Areas: MicrobiologyABSTRACT - Infections caused by gastrointestinal parasites have been described worldwide as one of the most important issues impacting small ruminant production. The systematic administration of anthelmintic (AH) drugs without following good practice principles has led to an increase in anthelmintic resistance (AR). There is scarce information regarding AH efficacy in small ruminants in Portugal. This study aimed to characterize by in vivo methods the presence and level of AR in four farms in the region of Lisbon and Tagus Valley. All four farms kept small herds in extensive management systems and used different deworming protocols. The active substances used were fenbendazole and a combination of mebendazole plus closantel in a dosage according to the manufacturers’ instructions. On day 0 (T0), fecal samples were collected from all study animals, and animals in the treatment group (n = 40) were dewormed with the AH previously chosen by the assistant veterinarian. Animals in the control group (n = 30) did not receive any AH drug. The fecal sample collection was repeated on day 15 (T15), and the control group was treated. Egg counts were performed using the McMaster method for the eggs per gram (EPG), and AR was evaluated by the fecal egg count reduction test (FECRT) with a 95% confidence level (CL). The results from this experiment indicated that the four farms presented AR with two farms to fenbendazole (FECRT of 48% and 85%) and two farms to mebendazole plus closantel (FECRT of 66% and 79%). These results indicate that the gastrointestinal parasites of the four studied Portuguese farms are resistant to benzimidazoles, which suggests an increase in AR regarding nematodes in small ruminant production systems in PortugalMDPIRepositório da Universidade de LisboaAntunes, Maria InêsLima, Miguel SaraivaStilwell, GeorgeRomeiras, Maria InêsFragoso, LuisMadeira de Carvalho, Luís2023-02-22T22:48:20Z2022-12-012022-12-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10400.5/27338engAntunes MI, Lima MS, Stilwell G, Romeiras MI, Fragoso L, Madeira de Carvalho LM. 2022.
