This study was conducted in Menofia governorate to determine the most
common infectious diseases in beef cattle and associated risk factors. A total of 450
samples were collected from 150 diseased beef cattle of different ages, sex and seasons.
Results of blood smears revealed that 14.7% were positive for blood parasites,
including 9.3% and 5.4% for Babesia and Theileria infection, respectively. Meanwhile,
fecal examination revealed that 67.3% were positive for at least one gastrointestinal

and 10% respectively. Risk factor analysis revealed that sex and season were significant
with Babesia infection, as the cold season and females gender were 6 times and 3.45
times more susceptible than the warm season and males, while in Theileria infection
older age animals were 3.27 times more susceptible than young age as well animal age
was the main significant risk factor in gastrointestinal parasitic infection as older age,
were 1.991 times the young age of attainment Trichostrongylus infection while older age
was 1.946 times the young age in Moniezia infection. Additionally, the season was
significant determinant in respiratory tract infections as cold season, was 15.27, 14.46,
