This study was conducted in Menofia governorate to determine the mostcommon infectious diseases in beef cattle and associated risk factors. A total of 450samples 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.

Regarding the bacteriological examinationrevealed that 92% were positive for bacterial culture; Klebsiella, Pseudomonas,Citrobacter, Proteus species and mixed infection represented 56%, 15.3%, 6%, 4.7%,and 10% respectively. Risk factor analysis revealed that sex and season were significantwith Babesia infection, as the cold season and females gender were 6 times and 3.45times more susceptible than the warm season and males, while in Theileria infectionolder age animals were 3.27 times more susceptible than young age as well animal agewas 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 agewas 1.946 times the young age in Moniezia infection. Additionally, the season wassignificant determinant in respiratory tract infections as cold season, was 15.27, 14.46,8.89, 4.48, 25.08 times more susceptible than warm season for Klebsiella, mixedinfection, Citrobacter, Proteus, and Pseudomonas respectively. In conclusion, this studyspot highlights on the most important infectious diseases among beef cattle in MenofiaGovernorate.
