Serological Investigation of Major Respiratory Viruses in Sheep in North Shewa, Ethiopia: Parainfluenza Virus, Bluetongue Virus, Maedi-Visna Virus and Peste des Petits Ruminants Virus.
Article in Veterinary medicine and science, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundRespiratory diseases significantly affect small ruminants, leading to considerable illness and mortality. These conditions are often multifactorial, resulting from interactions among pathogens, host immunity and environmental stressors.
objectiveThis study aimed to detect antibodies against major respiratory viruses, bluetongue virus (BTV), Maedi-Visna virus (MVV), parainfluenza virus type 3 (PI-3) and Peste des petits ruminants virus (PPRV) in sheep from the North Shewa Zone, Ethiopia.
methodsA cross-sectional serological survey was conducted between September and November 2018, involving 135 sheep from the Menz-Mama and Menz-Gera districts. Serum samples were analysed using enzyme-linked immunosorbent assays (ELISA): competitive ELISA for BTV and PPRV and indirect ELISA for MVV and PI-3. Data were analysed using STATA software, and descriptive statistics were used to estimate the frequency of antibodies against the target viruses.
resultsPI-3 showed the highest seropositivity (60.74%), followed by PPRV (27.41%), BTV (12.59%) and MVV (8.15%). Overall, 76.3% of sheep had antibodies to at least one virus, 26.67% to two viruses and 2.22% to three. In Menz-Mama, among 64 sheep tested, 3.13% were seropositive for MVV and PPRV, 37.5% for PI-3 and 18.75% for BTV. A total of 57.81% had antibodies to at least one virus and 3.13% to two. In Menz-Gera, higher seroprevalence was observed: 12.68% for MVV, 81.69% for PI-3, 49.3% for PPRV and 7.04% for BTV. A total of 92.96% of sheep had antibodies to at least one virus, 47.89% to two and 4.23% to three, indicating substantial viral exposure and potential co-infection.
conclusionsThese findings indicate widespread circulation of respiratory viruses, with PI-3 being the most seroprevalent. Integrated control measures, including enhanced surveillance, targeted vaccination and improved husbandry practices, are urgently needed to reduce the disease burden and support sustainable sheep farming in the region.
