Escherichia Coli And Antibiotic Resistance To Tetracycline Antibiotics, Taylor L. Dodgen
Escherichia Coli And Antibiotic Resistance To Tetracycline Antibiotics, Taylor L. Dodgen
Senior Honors Theses
Escherichia coli cells growing under ideal conditions are able to complete one reproduction cycle in as little as every twenty minutes. Since so many generations are able to be observed, one should theoretically be able to observe thousands of generations and determine evolution’s effects over a short period of time. In this experiment, E. coli K12 cells were cultured under ideal growth conditions but in the presence of antibiotics as a selective environmental stress in order to select for resistance. This was accomplished by serially passing colonies that were in close contact with two different, but similar antibiotics over a …

Application Of Mentofin^® In Broilers With Clinical Infectious Bursal Disease To Reduce Escherichia Coli Related Problems After Vaccination Against Newcastle Disease, K. Tayfun Çarli, Kaan Önat, Elçi̇n Günaydin
Turkish Journal of Veterinary & Animal Sciences
In this study Mentofin^® was used in commercial broiler chickens naturally exposed to infectious bursal disease virus (IBDV) and administered live Newcastle disease virus (NDV) vaccine to evaluate the ability of Mentofin^® to reduce Escherichia coli-related respiratory lesions, immunomodulate Newcastle disease (ND) vaccine response, change pharyngeal aerobic bacterial counts, and have certain impacts on specific production parameters. Mentofin^® was added to the drinking water (100 ml/500 l water) of broiler chickens aged between 3 and 5 days. ND and IBD vaccinations were administered via drinking water to 15-day-old chickens. NDV vaccination was given again when the chickens were 20 days …
