Detection of Bacterial Contaminant of Newborn Calves and Their DOMS Pens
The aim of this scientific job is to describe reasons for pathogen loading in the environment and ways to reduce this loading and determination of these pathogens . Most pathogens are opportunistic exploit the contamination of pens bed and hutches by different types of calves secretions and inflammatory exudates from the uterus and mammary gland . The large isolated pathogens were Escherichia coli and Staphylococcus aureus and one isolate represent a genus Klebsiella . The main drugs were more active against these bacteria after the sensitivity test has been done ; Enrofloxacen , Flurphenicol, Colistin Sulfate and combination of Sulfadiazine Vs Trimethoprim. Amoxicillin , Ampicillin and Tetracycline were less active.
In recommendation, good ventilation, exposure to sun light and proper disinfection of the pens will share in decrease the rate of infections when occurred through indirect contact. Sensitivity test has been applied from time to time for passing the drug resistance.
