Pure culture experiments were conducted to assess the bacteriostatic and bactericidal effects of phlorotannins (PT) isolated from Ascophyllum nodosum (brown seaweed) on Escherichia coli O157:H7. In Ex...
A study was conducted with 48 weaned barrows (283 d, 8.450.14 kg) to determine the effect of Achyranthes bidentata polysaccharide (ABPS) supplementation on pig performance, immunologic...
In 2004, J첩rgensen and coworkers proposed the MUC4 gene as a candidate gene of enterotoxigenic Escherichia coli (ETEC) F4ab/ac receptor in piglets and a mutation of G??C in intron 7 of MUC4 was...
摘要含有E. coli gaIK和gpt基因的重组DNA pPB22用显微注射法导入昆明白小鼠受精 卵,经发育,最后得到21只成年小鼠。其中1只小鼠的肝脏显示出E. coli gpt酶活性,但未检测出E. coli galK酶活性。印迹分子杂交表明,外源的pPB 22重组DNA已整合到2只小鼠的染色体上,其中包括那只肝脏中显示E. cola gpt酶活性的小鼠。 ...
A PCR-aided monitoring of verotoxin-producing Escherichia coli (VTEC) was performed over the period of 12 months by using fresh feces collected monthly from 5 dairy cows that had been identified as VT...
Enterotoxigenic Escherichia coli is a major cause of diarrhea in neonatal and post-weaning piglets. To determine the most common fimbrial antigens of ETEC in piglets with diarrhea, two investigations ...
Recombinant heterologous proteins can be produced as insoluble aggregates partially or perfectly inactive in Escherichia coli. One of the strateges to improve the solubility of recombinant proteins is...
Copper-bearing montmorillonite (Cu-MMT) was produced by Cu2+ cation exchange reaction. X-ray diffraction analysis showed that that the (001) basal spacing of the MMT crystal lattice increased from 1.5...
To isolate the β-galactosidase producing thermophilic bacteria, samples of mud and water were collected from hot springs of avolcanic area near Golden Springs in New Zealand. Among eleven isolated str...
Lectin activities and chemical characteristics of Escherichia coli, Lactobacillus spp. and Bifidobacterium spp. originating from the porcine cecal mucosal layer were studied based on hemagglutination ...
Compost is used mainly as an organic fertilizer, but it is also used as bedding material for cattle. Dairy cattle have been identified as a main reservoir of pathogenic Escherichia coli O157:H7. Furth...
An experiment was conducted to assess the interaction between genotypes and dietary lysine content in commercial broiler chicks by measuring growth, and response to sheep red blood cells (SRBC) and Es...
