| dc.description.abstract | Present study aimed at studying the outbreak epidemiology of anthrax in livestock in Karnataka. It also aimed in isolating and characterizing Bacillus anthracis from outbreak areas. A retrospective study over a period of 17 years was done based on the outbreak data available from ICAR-NIVEDI. It could be noticed that dry region of Karnataka were more affected than hilly zones and transition zones and number of outbreaks in coastal areas were nil. It was observed that highest number of outbreaks happened during September (13.13%) followed by August and October which are post monsoon and monsoon seasons of Karnataka. Least number of out breaks occurred during April and May which are dry season. Statistical analysis revealed that the environmental factors soil pH (6.98 ± 0.01), soil moisture (24.77 ± 2.52) %, available soil calcium (921 ± 75.97) mg/kg, soil potassium (128.39 ± 64.17) ppm and wind velocity (2.96 ± 0.68) km / hrs have positive impact on presence of anthrax. Risk prediction map revealed that north eastern taluks and south eastern parts of Karnataka are the risky zones in further outbreaks. In outbreak investigation study, it was possible to find that sheep were the species and 1 to 3 years were the age group primarily affected. Unscientific housing, unscientific disinfection, carcass management and absence of proper vaccination were the important management practices noticed to be the cause of initiation of disease and creation of incubator areas. Upon isolation and characterization, 13 out of 17 clinical samples collected from different areas of Karnataka were found to be positive for Bacillus anthracis and confirmed through PCR. Five out of 15 soil samples were positive for anthrax. Phylogenetic analysis revealed that all field isolates collected during the study grouped in same clad. | en_US |
