“…in donkeys was 11.8% using a competitive-ELISA (MACHACOVÁ et al, 2013) and in Colombia, 11 of the 56 examined donkeys presented antibodies against Neospora spp. measured by Dot-ELISA (BLANCO et al, 2014). Due the different methodology used in the studies, comparisons between these studies and the present study are difficult to make.…”

Sarcocystis neurona and Neospora hughesi are coccidian protozoa that can cause neurological illness in horses in America. In this study we report seroprevalence of Neospora spp. andS. neurona in sera of 333 donkeys from the northeastern region of Brazil. Antibodies to Neospora spp. were detected in 2% (7 donkeys) of 333 sera tested by the indirect fluorescent antibody test (IFAT) with a cut-off dilution of 1:40. Antibodies to S. neurona were found in 3% (10 donkeys) of the samples tested by IFAT (cut-off ≥50) and 21% (69 donkeys) by the direct agglutination test (SAT ≥50). The SAT and IFAT results for S. neurona showed a poor concordance (value of Kappa=0.051). This is the first report ofNeospora spp. antibodies in Brazilian donkeys and the first detection of antibodies against S. neurona in this animal species.

“…and S. neurona exposure in donkeys (Equus asinus) from other countries is scarce (MACHACOVÁ et al, 2013;BLANCO et al, 2014). Donkeys are used traditionally for working roles, however in some parts of the world they are increasingly being used for milk production.…”

“…The majority of the South American studies were conducted in Brazil, with only two out of twelve studies conducted in Colombia. The studies conducted in Colombia reported seroprevalence rates of 1.23% using IFAT assays [25], and one study utilized ELISA assays, reporting a seroprevalence of 19.7% [18].…”

Equids can be infected by Neospora spp., and its infection is associated with neurological and reproductive disorders. This systematic review and meta-analysis aimed to assess the prevalence of anti-Neospora caninum antibodies in horses, donkeys and mules worldwide between 2012 and 2022. Five scientific databases were consulted: MEDLINE, ScienceDirect, PubMed, LILACS and SciELO, using the descriptors “protozoan” or “neospora” AND “horses” or “donkeys” or “mules”. A total of 1909 studies were screened, and 25 studies met the inclusion criteria. The pooled prevalence of Neospora spp. infection in equids, based on a total of 11,076, was 8.34% (95% CI: 4.78–14.17%). Further analysis by species revealed no statistically significant difference in the prevalence of Neospora spp. infection across equids: 8.5% (95% CI 5.03–13.99%) in horses, 7.36% (CI 2.08–22.94%) in donkeys and 6.07% (95% CI 0.71–36.83%) in mules. Regarding diagnostic tests, the prevalence of Neospora spp. infection determined by the indirect fluorescent antibody test (IFAT) was 8.08% (95% CI: 3.74–16.61%), by the enzyme-linked immunosorbent assay (ELISA) was 7.91% (95% CI: 3.71–16.08%), and by the modified agglutination test (MAT) was 20% (95% CI: 15.37–25.60%). This meta-analysis provided valuable and comprehensive insights into the prevalence of Neospora spp. infection in horses, donkeys, and mules using serological detection methods. The results highlight the wide distribution of Neospora spp. infection in equids across all continents, indicating the importance of this infection. Transmission of the parasite can occur both horizontally (directly between animals) and vertically (from mother to offspring), further emphasizing the significance of understanding and managing this infection in equid populations.

“…In another study in Brazil, researchers found antibodies to Neospora in 2 of 500 donkeys studied using IFAT (cut-off 1:100) [ 6 ]. Antibodies to Neospora were also reported in 11 (19.7%) of 56 donkeys from Colombia by using Dot-ELISA [ 2 ], in 52 (52%) of 100 donkeys from Iran by the Neospora agglutination test (NAT, cut-off 1:80) [ 8 ], and 28 (11.8%) of 238 donkeys from Italy by using competitive inhibition ELISA [ 12 ]. Again, comparison of seroprevalences among the studies should be interpreted cautiously because of different laboratory methods used to detect anti- Neospora antibodies.…”

Seroepidemiology ofSarcocystis neuronaandNeospora hughesiinfections in domestic donkeys (Equus asinus) in Durango, Mexico

et al. 2017

There is currently no information regarding Sarcocystis neurona and Neospora hughesi infections in donkeys in Mexico. Here, we determined the presence of antibodies against S. neurona and N. hughesi in donkeys in the northern Mexican state of Durango. Serum samples of 239 domestic donkeys (Equus asinus) were assayed for S. neurona and N. hughesi antibodies using home-made enzyme-linked immunoassays; six (2.5%) of the 239 donkeys tested seropositive for S. neurona. The seroprevalence of S. neurona infection was comparable among donkeys regardless of their origin, health status, or sex. Multivariate analysis showed that seropositivity to S. neurona was associated with increased age (OR = 2.95; 95% CI: 1.11–7.82; p = 0.02). Antibodies to N. hughesi were found in two (0.8%) of the 239 donkeys. Both exposed donkeys were healthy, 3- and 6-year-old females. This is the first evidence of S. neurona and N. hughesi infections in donkeys in Mexico.
