Outline of Final Research Achievements

Present study performed to analysis what kind bacteria and blood paracyte are there in crow for showing whether crow can be candidate carrier of pathogen or not. It was shown that many crows have Haemoproteus, Leucocytozoon and filalia. The micro biotas of three crows also contained potentially pathogenic bacteria such as Campylobacter and Brachbacter. Intestinal micro biomes revealed the high frequency existence or vestige of potentially pathogenic microorganisms.
GPS data Logger analysis showed crows used livestock barns to get food throughout the year. Considerable number of crows moved between multiple barns, suggesting they might be vectors in the transmission of infectious disease. Further study showed that crows usually moved within approximately 4~5km and very few of them moved 100km during 2 month.
