Comparing McMaster and Mini-FLOTAC for endoparasites diagnostic in goats

Abstract

The Brazil Northeast region has the higher goat national herd with the endoparasitosisas one of the main factors interfering in these productive chain. Aiming to compare diagnostic techniques to quantify goats endoparasites eggs and oocysts. Eggs and oocysts recovered from feces were identified from 45 goats, Capra aegagrus hircus, by counting eggs per gram of feces (EPG) McMaster (conversion factors 100x and 25x) and Mini-FLOTAC (conversion factors 5x and 10x). The statistical analysis were performed in the SPSS program version 21.0 and the statistical differences and accordance between the techniques, by Friedman (p<0.05) and kappa (p-value), respectively. Eggs from Strongylida, Strongyloidessp., Trichurissp. and Eimeriasp were identified. The coproparasitological methods applied were efficient in quantifying and identifying recovered eggs and oocysts. Although the similarity and accordance among techniques regarding the Eimeriasp. oocysts, the McMaster 25x; Mini-FLOTAC 5x and Mini-FLOTAC 10x were the methods that better recovered such oocysts. The Strongylida eggs were equally recovered by all the techniques. The Strongyloidessp. eggs were better recovered by the McMaster 25x; McMaster 100x and Mini-FLOTAC 5x techniques; and the Trichurissp. by McMaster 100x. Considering that both techniques used in this work were capable on recovering every eggs and oocysts, both can be adopted for coproparasitological diagnostic in goats.

A comparison of Mini-FLOTAC and McMaster techniques, overdispersion and prevalence of parasites in naturally infected North American bison (Bison bison) in the USA

“…Several studies comparing the Mini-FLOTAC and the McMaster techniques have focused on strongyle egg counts. In ruminants, such comparisons have been performed on cattle samples ( Bosco et al., 2014 ; Dias de Castro et al., 2017 ; Paras et al., 2018 ; Amadesi et al., 2020 ; Elghryani et al., 2020 ), sheep samples ( Rinaldi et al., 2014 ; Kenyon et al., 2016 ; Bosco et al., 2018 ; Paras et al., 2018 ; Alowanou et al., 2021 ; Vieira et al., 2021 ), goat samples ( Silva et al., 2020 ; Alowanou et al., 2021 ; Vieira et al., 2021 ) and llama samples ( Paras et al., 2018 ). Eimeria spp.…”

Winning strategies against Hemonchus

“…This method for controlling parasitism in the face of anthelmintic resistance of nematodes has been validated for use in sheep and goats in the U.S., with strong correlation to fecal egg per gram count and packed cell volume. 4 Fecal egg counts (FEC) performed by the Mini-FLOTAC or McMaster's methods [5][6] are important to perform periodically as a more quantitative method of monitoring, as well as determine other parasite genera that may be circulating in the herd or flock. Remember, FAMACHA only detects anemia, which is produced by Hemonchus.…”
