Seroprevalence of Brucella antibodies in Donkeys (Equus asinus) in Yobe south senatorial zone, Northeastern Nigeria.

Abstract: A cross-sectional survey was conducted to determine the seroprevalence and risk factors influencing the presence of Brucella spp. antibodies in donkeys in Yobe south senatorial zone, Nigeria. The study was aimed at determining the importance of Brucella spp. infection in donkeys (Equus asinus). A total of 200 sera samples from of 105 males and 95 female donkeys were collected and screened for brucellosis using the rose bengal plate test (RBPT) and the indirect enzyme-linked immunosorbent assay (iELISA). Data obtained were analyzed to determine associations and risk factors. The analysis revealed that 21.5% and 18.5% were seropositive by RBPT and iELISA respectively, with 22.0% and 20.0% of the male and female donkeys being seropositive by RBPT, and 19.0% and 17.9% of the male and female donkeys being seropositive by iELISA, respectively. There was a statistically significant association between donkey age and positive rate of iELISA for detecting Brucella infection. Though the positive rate was higher for males than females, there was no statistically significant association between sex and location of donkeys and the sensitivities of RBPT and iELISA for detecting Brucella infection. In conclusion, this study indicates that brucellosis exists with high seroprevalence particularly among male and adult donkeys and is of public health significance and economic importance because it can lead to infertility and abortion in the stock.

This research article focuses on a survey investigating the prevalence and influencing factors of Brucella bacteria infection in donkeys in Northeastern Nigeria. The study found that brucellosis, the disease caused by the bacteria, is of public health and economic concern due to its high presence in these animals, and its potential implications for fertility and abortion.

Study Objectives and Methods

  • The purpose of this research was to conduct a wide-ranging survey to measure the prevalence of Brucella spp. antibodies in donkeys, with a specific focus on the donkey population in the Yobe south senatorial region of Nigeria.
  • The study aimed to highlight the implications of Brucella spp. infections in donkeys (Equus asinus) which is crucial for managing the animal health and consequently public health.
  • The researchers collected a total of 200 sera samples from 105 male and 95 female donkeys.
  • These samples were then screened for evidence of brucellosis using two different techniques: the rose bengal plate test (RBPT) and the indirect enzyme-linked immunosorbent assay (iELISA).

Results

  • A total of 21.5% and 18.5% of the samples tested positive for antibodies to Brucella spp. by the RBPT and iELISA tests, respectively.
  • When broken down by sex – 22.0% and 20.0% of the male and female donkeys tested positive by RBPT, and 19.0% and 17.9% of the male and female donkeys tested positive by iELISA, respectively.
  • The data analysis revealed a significant correlation between the age of the donkeys and the positive rate of detection of Brucella infection by the iELISA.

Conclusions

  • Despite the higher rate of prevalence in male donkeys, there was no statistically significant correlation found between the sex and location of the donkeys and the sensitivities of the RBPT and iELISA tests.
  • The findings imply that brucellosis is a prevalent issue in the examined donkey population, particularly amongst the adult and male segments of the population. This has serious public health implications as well as economic implications: the infection could lead to infertility and abortion in the animals.
