Prevalence of Gastrointestinal Nematodes, Cestodes, and Protozoans of Goats in Nyagatare District, Rwanda

Abstract

Goat farming significantly contributes to the efficient use of land and socioeconomic development in developed and developing countries. During the fiscal year 2017-2018, goats made up 13.5% of the total live livestock exported by Rwanda. Gastrointestinal parasites (GIPs) can negatively impact goat production, especially in developing countries like Rwanda. This study aimed to determine the impact of the goat' age and location (administrative cell) on the prevalence of gastrointestinal nematodes, cestodes, and protozoans (GiNCPs) of goats in Nyagatare district, Rwanda. Methods: In this cross-sectional study, 149 faecal samples were collected from apparently unwell goats and analyzed using the simple flotation technique. Strongyle-type nematodes (STNs) infections were graded using the McMaster method. Pearson chi-square tests of independence were calculated to assess the impact of the goat' age and location on the prevalence of GiNCPs in the study area. Results: All the goats (100%) were infected with GiNCPs. The identified types of parasites were STNs (96.0%), Coccidia (83.2%), Moniezia spp (14.8%), Strongyloides papillosus (12.8%), Nematodirus spp (0.7%) and Trichuris ovis (0.7%). Nearly 85.9% (128/149) of the goats were coinfected with 2 to 4 types of parasites and the coinfection of STNs and coccidia preponderated at 58.4%. The location (administrative cell) of the goats correlated with the prevalence of monieziasis (p<0.05). The goat's age category was also associated with the prevalence of strongyloidiasis (p<0.05). Conclusion: All the goats (100%) were infected with GiNCPs. The location (administrative cell) of the goat also correlated with the prevalence of monieziasis. In addition, the goat's age category was associated with the prevalence of strongyloidiasis. These findings show that any control program for caprine gastrointestinal parasitoses in the study area should focus on STNs and Coccidia.

Gastrointestinal nematodiasis of goats in Somali pastoral areas, Ethiopia

“…The current study found that the overall prevalence of GINs in goats in the study area was 54.17%, which agrees with prevalence reports of 52.67% from Hararghe, eastern Ethiopia ( Belina et al, 2017 ) and 53.29% from Haramaya, eastern Ethiopia ( Ahmed et al, 2017 ). However, it is comparatively lower than prevalence reports of 78.2% from Alage, Southern Ethiopia ( Moje et al, 2021 ) and 100% nematode prevalence in goats from Nyagatare district, Rwanda ( Tumusiime et al, 2022 ). Similarly, the current study disagrees with prevalence reports of 42.1% in Tullo district, western Hararghe, Ethiopia ( Getachew et al, 2017 ) and 26.6% of GINs prevalence in goats from Damaturu, Yobe State, Nigeria ( Adamu and Kyari, 2023 ).…”

“…Sorghum, maize, barley, wheat, and beans are among the most widely farmed crops. The estimated goat population in the district is approximately 13,885 ( CSA, 2016 ; Tumusiime et al, 2022 ) (See Fig. 1 ).…”

Gastrointestinal parasites in free grazing goats from Ayacucho, Peru: prevalence and risk factors associated with infection in herds

“…Thailand with 87.2%(Wuthijaree et al, 2022), and Ethiopia with 54.17% (Hussein et al, 2023)(Cardoso et al, 2012), and in Rwanda with a prevalence of 100%(Tumusiime et al, 2022). Regarding previous studies carried out in the area of Ayacucho, Mendoza (2023) found a prevalence of 100% in creole goats from the district of Pacaycasa, Ayacucho, during the rainy season.…”

“…Then the coverslip was carefully placed on a slide and taken to the microscope (OPTICA B-292®). Positive samples were analyzed using a modi ed McMaster protocol (Tumusiime et al, 2022), to assess the number of eggs/oocysts per gram of feces. Intensity burdens (low, moderate, and high) were evaluated according to Taylor et al (2007).…”

“…Goat farming is one of the livestock activities that contribute to the socioeconomic growth of developing regions (Tumusiime et al, 2022), ensuring food security and offering economic income to smallholders in rural areas (Monau et al, 2020). In Peru, goat population is distributed between the mountains and the coast, concentrating in the regions of Piura, Ayacucho, Ica, and Lima, where about 9.64% of the total population is located in Ayacucho (MINAGRI, 2021).…”
