Abstract

Background: Haemoparasite infections represent a major cause of equine morbidity and mortality. This study was conducted to determine the prevalence, species distribution, and risk factors of these infections among horses in Kwara and Niger States, North Central Nigeria. Purpose: Investigating the occurrence of both single and mixed haemoparasite species, this research examined how factors such as age, body condition, and packed cell volume (PCV) influence infection rates in apparently healthy horses. Method: Sampling was performed on 102 apparently healthy horses, followed by blood collection and analysis via wet mount and thin blood smear techniques. Evaluation of the PCV was achieved using the haematocrit technique. For statistical analysis, univariate logistic regression was employed, with a value of p<0.05 considered statistically significant. Results: Positivity for at least one haemoparasite species was identified in 57 horses, representing 55.88% (95% CI: 46.21–65.13) of the sampled population. Detected were five distinct species: Anaplasma phagocytophilum, Babesia caballi, Theileria equi, Microfilaria of Setaria equina, and Trypanosoma equi identified as the most abundant at 34.31% (95% CI: 25.82–43.95). Furthermore, significant predictors associated with infection prevalence were determined to be age, body condition score, sex, PCV count, and horse ownership. Conclusion: Raised by the high infection rate in the study area is a noticeable concern regarding equine health. Underscored by these findings is the necessity for stringent control of ticks and other arthropod vectors to curtail the transmission of haemoparasites among horses within the region and across Nigeria.

Abstract

Background: Trichodina spp. are common ectoparasites of cultured fish and are associated with impaired health and productivity. Purpose: This study examined the prevalence, organ distribution, and host related factors associated with Trichodina infestation in farmed Clarias gariepinus. Method: Ninety five farmed C. gariepinus were randomly sampled from concrete, earthen, and plastic tank production systems. Gill, skin, and fin scrapings were examined for Trichodina infestation using wet mount preparations. Sex, total length, body weight, and Fulton’s condition factor were also assessed. Parasites were identified using standard parasitological techniques. Associations between infestation status and categorical variables were evaluated using chi-square tests. Differences in Fulton’s condition factor between infested and non infested fish were assessed using an independent samples t-test. Statistical significance was established at p < 0.05. Results: The overall prevalence of Trichodina infestation was 42.1% (40/95). The gills were the most frequently affected site (67.5%), followed by the skin (40.0%) and fins (12.5%). Sex was not significantly associated with infestation (χ² = 0.24, df = 1, p = 0.62). However, significant associations were observed between infestation and total length (χ² = 11.02, df = 4, p = 0.026) and body weight (χ² = 13.67, df = 6, p = 0.033), with higher prevalence in intermediate to larger sized classes. Infested fish had significantly lower Fulton’s condition factor compared with non infested fish (t = 2.31, df = 93, p = 0.023). Conclusion: Findings from this farm level investigation demonstrate an association between Trichodina infestation, organ specific distribution, host size, and Fulton’s condition factor in farmed African catfish under routine aquaculture conditions. Routine parasitological surveillance, improved farm management practices may therefore be important for reducing parasite burdens, promoting fish health and productivity.
