  • Lechtenberg, K.F.; Nagaraja, T. G.; Chengappa, M. M. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1998)
    Antibiotic susceptibility patterns of thirty-seven isolates of Fusobacterium necrophorum (21 biotype A and 16 biotype B) from liver abscesses of feedlot cattle were determined. These isolates were generally susceptible ...
  • Paddock, Zachary; Shi, Xiaorong; Bai, Jianfa; Nagaraja, T. G. (2012)
    Shiga toxin-producing Escherichia coli (STEC), particularly O157, are major food borne pathogens. Non-O157 STEC, particularly O26, O45, O103, O111, O121, and O145, have also been recognized as a major public health concern. ...

    Fusobacterium necrophorum was the predominant bacterial isolate from liver abscesses of feedlot cattle fed with or without tylosin. The major difference in the bacterial flora of liver abscesses between cattle groups was ...
  • Lechtenberg, K.F.; Leipold, H.W.; Nagaraja, T. G. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1986)
    Fusobacterium necrophorum was the predominant bacterial isolate from 49 liver abscesses. Biotype A tended to occur in pure infections and produced a more severe tissue reaction than biotype B, which tended to occur as a ...
  • Harmon, D.L.; Nagaraja, T. G. (Kansas Agricultural Experiment Station, 1986)
    The ruminant animal has the unique advantage of microbial digestion in the rumen. This relationship between host animal and microbial population presents some unique advantages and disadvantages to the animal in terms ...

    Four-ruminally fistulated, multiparous, pregnant Holstein cows were studied to characterize ruminal adaptations during the transition from gestation to lactation. Cows were fed typical far-off and close-up diets, a late ...
  • Park, A.F.; Titgemeyer, Evan C.; Cochran, R.C.; DeFrain, J.M.; Ferdinand, E.E.; Wallace, N.; Nagaraja, T. G.; Johnson, D.E.; Shirley, John E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2002)
    We used four ruminally fistulated, multiparous, pregnant Holstein cows to delineate microbial adaptations in dairy cows as they experienced the transition from one lactation to the next. Diets consisted of typical ...
  • Park, A.F.; Titgemeyer, Evan C.; Cochran, R.C.; DeFrain, J.M.; Ferdinand, E.E.; Nagaraja, T. G.; Johnson, D.E.; Shirley, John E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2002)
    Four-ruminally fistulated, multiparous, pregnant Holstein cows were used to delineate changes in ruminal fermentation in dairy cows as they experienced the transition from one lactation to the next. Diets consisted of ...
  • Butler, B.A.; Loneragan, G.H.; Thomson, Daniel U.; Nagaraja, T. G.; Reinhardt, Christopher D. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2012)
    Of all food safety challenges facing the beef industry, Escherichia coli O157:H7 has consistently presented the greatest economic remonstrance to meat packers and retailers. Cattle naturally shed E. coli O157:H7 in their ...
  • Narayanan, S.; Okwumabua, O.; Staats, J.; Oberst, Richard D.; Nagaraja, T. G.; Chengappa, M. M. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1998)
    DNA finger printing (restriction fragment length polymorphism analysis) was employed to genetically compare Fusobacterium necrophorum isolates of liver abscesses, ruminal wall, and ruminal contents from the same animal. ...
  • Paddock, Z. D.; Bai, Jianfa; Shi, X.; Renter, David G.; Nagaraja, T. G. (2013)
    A multiplex PCR was designed to detect E. coli O104:H4, a hybrid pathotype of Shiga toxigenic and enteroaggregative E. coli, in cattle feces. A total of 248 fecal samples were tested and 20.6% were positive for the O104 ...
  • Clary, E.M.; Brandt, Robert T., Jr.; Nagaraja, T. G. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1990)
    Batch culture fermentations were used to determine the effects of fat type [none, animal tallow (AT), soybean oil soapstock (SOY), or yellow grease (YG)] and ionophore type [none, lasalocid (L), monensin + tylosin in a ...
  • Bartley, E.E.; Nagaraja, T. G. (Kansas State University. Agricultural Experiment Station, 1983)
    Lasalocid or monensin (600 mg per 1000 lb body weight daily) was tested on cattle bloating on high grain diets. Bloat was reduced 92% by Lasalocid and 64% by monensin. When fed throughout the finishing period, lasalocid ...
  • Lintzenich, B.A.; Cochran, R.C.; Vanzant, E.S.; Beaty, J.L.; St. Jean, G.; Brandt, Robert T., Jr.; Nagaraja, T. G. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1993)
    Sixteen ruminally fistulated steers were used to study the effects of supplemental alfalfa level (.25 or 1.0% body weight [BW]) and method of processing (hay or pellets) on wheat straw utilization. Response to increased ...
  • Coe, M.L.; Wallace, N.; Kemp, K.E.; Parrott, J.C.; Nagaraja, T. G. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1996)
    Twelve ruminally cannulated Holstein steers were used to determine the effect of monensin (0, 20, 30, and 40 g/ton) on grain bloat. Steers were fed a bloat-provocative, high-grain diet at 1% of body weight twice daily. ...
  • Beharka, A.A.; Nagaraja, T. G.; Morrill, J.L. (Kansas Agricultural Experiment Station, 1990)
