ABSTRACT:
Geographical Information
Science (GIS) technologies have been used increasingly for ecology and
epidemiology of water-borne diseases, providing approach for animal health
issues. This study was set up to investigate the geographical distribution of
Bovine that was affected by Leptospira hardijo, in River Nile state, on
October 2012. Locations of targeted cattle were delimited using GPS. Fifty
three (53) of blood samples were collected, and screened in the laboratory for Leptospira
hardijo specific antibodies using indirect ELISA. 15.09% had evidence of
infection as determined by the presence of anti-leptospira antibodies. It was
inferred that no incidences were recorded in 45 locations out of the 53
selected locations in the state. Leptospirosis risk area for transmission was
mapped using 5 km buffer distance. Animals’ movements routes were mapped with
their contacts area and positive samples locations, hafair locations where
animals contacts were mapped. This study demonstrated the value of GIS and GPS
in disease mapping for animals’ health, and this might help
veterinary authorities to implement strategic interventions for animal disease
control.
