A longitudinal study was undertaken to investigate E. coli using standard biochemical and sugar fermentation tests. Faecal samples were taken from calves purposively three selected dairy farms in Bishoftu Ethiopia. Four different sampling times used observe the detection rate of coli. The overall 84/104 (80.70%). isolates points ranged 16.34% 25.00% which occurrence E.coli has a significant association. All isolated showed patterns. biotyped into 14 biotypes variation occurred for during first fourth points, pattern ranging 20.20% 31.00%. Among biotypes, VI III dominate with 55.95% 16.67% respectively. biotype (predominantly group VI) distribution concerning time have association (p=0.039).Diverse natures variations observed as main determinant. Farm management practice could reduce pathogen farm animals, particularly neonatal calves.
