Active surveillance and associated epidemiological risk factors of caprine paratuberculosis in selected district of Odisha, India.

Caprine paratuberculosis (PTB) is a progressive, debilitating and production-limiting disease that causes significant economic losses and raises public health concerns. The goal was to study active surveillance and associated epidemiological risk factors of caprine PTB in selected district of Odisha, India. The 818 goats of various ages, sexes and breeds were randomly screened in ten different districts for a year based on history, clinical signs and fecal smear examination using the Ziehl-Neelsen stain, yielding an overall prevalence of 38.75%, with clinical and sub-clinical PTB at 8.06 and 30.68%, respectively. A molecular tool, IS900 polymerase chain reaction, was also used to confirm the disease. With subsp (MAP) bacilli and endoparasite infections, the majority of affected goats (69.08%) were low shedders. Puri coastal district had the highest prevalence (52.29%) followed by Sambalpur (48.61%), while Khordha had the lowest prevalence (26.41%). Caprine PTB was more common in goats over 2 years old (51.23%), in the Ganjam breed (42.30%), in females (39.17%) and in goats housed on earthen floors (55.83%) according to chi-square analysis. The current study concluded that higher (30.68%) observations of subclinical PTB were cause of real concern due to its insidious spread as well as its zoonotic significance with potential human consequences, which requires immediate attention at all levels. Because of the public health importance of this hidden killer disease, the current findings would be useful in developing a roadmap for implementing prevention and control policies, prompting provision for adequate funding with elaborative research.
