Prevalence, seasonal and geographical distribution of parasitic diseases in dogs in Plateau State Nigeria: a 30-year retrospective study (1986-2015).

Abstract

Parasitic diseases of dogs are now major economic and public health issues in Nigeria due to indiscriminate reproduction of dogs, lack of appropriate policies on pet ownership and diseases control as well as inadequate veterinary care. In order to understand the prevalence, seasonal variation and distribution of parasitic diseases of dogs in this region of Nigeria, the present study conducted a 30-year retrospective analysis in the referral veterinary centre, Vom, and analysed data using the Chi square test and the factor analysis. Of the 26,844 dogs handled between January 1986 and December 2015, 17,663 (65.8%) had different parasitic diseases. Yearly distribution of parasitic diseases varied significantly (p < 0.0001) and ranged between 52.0 and 85.4%. Age, seasonal and disease specific prevalence rates ranged between 2.8 and 80.5%. Prevalence rates in females 78.2% (95% CI 77.6-78.9) and indigenous breed 70.0% (95% CI 69.2-70.7) were significantly higher (p < 0.0001) from those of the males 47.2% (95% CI 46.2-48.1) and exotic breeds of dogs 60.7% (95% CI 59.8-61.6), respectively. Ancylostomosis was the most prevalent (15.9%) disease while Barkin Ladi recorded the highest regional prevalence. It is pertinent to enact appropriate disease control policies and observe control programmes including vector control and improved hygiene to curtail the economic and public health threats associated with these diseases.
