  Since, last several years, efforts are going on to eradicate or eliminate a number of infectious diseases of animals, with mixed success. Basically for eradicating, eliminating or controlling any infectious disease isolation and quarantine of sick animals as well as animals suspected for disease; strengthening disease monitoring and surveillance, effective vaccines and vaccination strategies along with other control measures including of treatment are of utmost importance. Most importantly a significant knowledge is required for countering infectious diseases and assessing the criteria for selection of disease to be eradicated next. The role of environmental factors in the process of disease dynamics need to be understood which further plays a contributory role in the process of combating and elimination of diseases. Despite continuous efforts against animal diseases like Rinderpest, Contagious bovine pleuropneumonia (CBPP) and Foot-and-mouth disease, Rinderpest (cattle plague) is the only one that is successfully eradicated till date in India. However, control programmes on CBPP also brought a significant reduction in the incidence of the disease but eradication status is yet to be declared. While the other disease control programmes viz., Foot-and-Mouth Disease Control Programme (FMDCP), National Control Programme on Brucellosis (NCPB), National Control Programme of Peste des Petits Ruminants (NCPPPR) and Avian Influenza: Preparedness, Control and Containment could not achieve the desired success. Nowadays, with the achievement of the global eradication status on rinderpest there is again a renewed interest in disease eradication and control of infectious diseases of animals and alleviating their public health concerns. The focus is also being given in the 12th five year plan of the country on monitoring and control of certain animal diseases of economic importance. In view of above facts, this is right time to discuss the strategies for combating and eradicating important infectious diseases of animals with particular reference to India, achievements of global rinderpest eradication programme and reasons thereof and possibly apply lessons while planning for the future activities. This article describes various prevention and control strategies for controlling the infectious diseases of animals that have been or should be targeted for eradication or elimination, direct and indirect benefits from control programmes, issues and opportunities for the future.

  Background: Johne’s disease is chronic incurable enteritis mainly responsible for reduced productivity in domestic livestock leading to extensive economic losses to the dairy industry world-wide. Therapeutic efficacy of ‘First indigenous vaccine’ developed using novel ‘Indian bison type’ biotype of Mycobacterium avium subspecies paratuberculosis (MAP) strain ‘S 5’ was evaluated for the treatment of clinical Johne’s disease in the farm herds of Jakhrana breed of goats. Farm herds of this important milch breed of semi-arid region of Rajasthan were endemically infected with Johne’s disease. Materials and Methods: Response to ‘Indigenous vaccine’ against Johne’s disease has been studied twice in this farm unit, first time in 2006-07 (Vaccine trail-I) and second time in the present study from 2013-14 (Vaccine trial-II). Data on improvement in health, clinical condition, productivity, reproductive performance, milk yield, survivability, morbidity, mortality, culling and shedding of MAP in feces were recorded before and after vaccination. In vaccine trial-II, 225 adult goats and 70 and 39 kids (above 3 months age) born to un-vaccinated and vaccinated goats were vaccinated one time between 2013 and 2014, respectively. Results: Reduction in shedding of MAP in this vaccine trial-II of infected goats and 1st generation kids was 45.5 and 100.0%, respectively. Presence of MAP in the blood of vaccinated goats was reduced by 23.0% at 360 DPV. Peak titers were achieved around 90 DPV and all vaccinated goats sero-converted by 360 DPV. High to very high morbidity, mortality and cullings encountered before vaccination in the infected Jakhrana goatherds were mainly due to Johne’s disease and were highly reduced after vaccination. Vaccination not only reduced clinical disease but also improved production performance (milk and meat production). Average gain in body weights were distinctly superior in the vaccinated goats and in the 1st generation kids born to vaccinated mothers. After vaccination there was overall improvement in the health of animals, kid survival rate, per animal productivity with respect to milk production and growth rates. Conclusion: Study concluded that ‘Indigenous JD vaccine’ developed using native MAP biotype can be employed both for the ‘Therapeutic management’ of the disease in the endemically infected goatherds and for the prevention of disease in naive and non-infected goats. The study can serve as model for the utilization of large population of non-productive domestic livestock and for the management and control of incurable Johne’s disease in endemically infected herds and flocks in the country.

  Bio-load of Mycobacterium avium subspecies paratuberculosis was estimated in the first mass screening of human population in Mathura region of South Uttar Pradesh. Of the 48,919 samples collected between December, 2010 and March, 2013 from Pathology laboratories, 26,390 were screened by indigenous ELISA kit, IS900 blood and stool PCR, IS1311 PCR_REA and stool microscopy. Of the 23,196 serum samples screened by indigenous ELISA, 34.0% were positive for MAP infection (Mathura-35.4% and Agra 14.2%). Percent prevalence of MAP infection was 28.3, 41.8, 37.4, 29.5, 41.1, 40.7, 42.5, 36.5 and 51.2 in patients suspected for diabetes, liver disorders, anaemia, thyroid disorder, tuberculosis, typhoid, abdominal disorders, inflammatory illness and ion imbalance, respectively. Of 3093 blood samples screened by IS900 PCR, 8.4% were positive (Mathura-9.2% and Agra-7.9%). Percent prevalence of MAP was 4.8, 7.0, 20.0, 4.9, 17.8, 7.6 and 12.7 in patients suspected for diabetic, liver disorder, skin disorders, anaemia, Malaria, typhoid and apparently normal individuals, respectively. Of the 101 stool samples screened by microscopy, 5.9% were positive and of these 2.9% were confirmed by IS900 PCR. IS1311 PCR_REA bio-typing showed ‘Indian Bison Type’ was the most prevalent biotype. Study indicated large scale exposure of human population to MAP infection in the Mathura region of South Uttar Pradesh and like in animals‘Indian Bison Type’ was the most prevalent biotype of MAP infecting human beings in this region.
