A study was carried out in Kamuli and Hoima districts in Eastern and Western regions of Uganda to
determine the Taenia solium porcine cysticercosis (PCC) and gastrointestinal (GI) parasites coinfection
status in pigs.
Materials and Methods:
One hundred and sixty-one households were selected randomly and visited between November and
December 2019. A household questionnaire was administered, and fecal and blood samples were
collected. Taenia spp. circulating antigen levels in the sample sera was tested using a commercial
enzyme-linked immunosorbent assay kit, apDia™ cysticercosis Ag ELISA. The modified McMaster
technique was used to identify and quantify the GI parasites.
The apparent animal level seroprevalence for PCC was 4.8% (95% CI 2.7 – 7.1) and differed across
the two districts (P = 0.018). At the pig herd level, the prevalence was 9.7% (5.5 – 14.4). The
prevalence of the different nematode eggs and coccidian oocysts in the two districts were as follows:
Strongyles 79.0% (95% CI 74.3 – 83.6), Coccidia 73.3% (95% CI 68.3 – 78.6), Trichuris spp. 7.4%
(95% CI 4.9 – 10.6), Strongyloides ransomi 2.1 (95% CI 0.7 – 3.5), Ascaris spp. 4.9 (95% CI 2.8 –
7.4). Overall, across the two districts, the arithmetic mean for the oocysts per gram (OPG) for
coccidia was 2042.2±5776.1 and eggs per gram (EPG) was highest in strongyles 616.1±991.
Overall, 57.4% of the porcine cysticercosis seropositive pigs were also positive for at least one of
the gastrointestinal helminths, which included strongyles, Strongyloides ransomi, Trichuris spp. and
The co-infection status of pigs with both PCC and GI parasites demonstrated by this study can
provide an incentive for integrating the control and management of both parasites with oxfendazole.
