Antimicrobial Activity.
A method using scanning electron microscope to study the morphology of the bacterial and fungal microbes and thus determining antimicrobial activity is presented in the chapter.
Evaluation of plasma cortisol and TBARS levels in calves after short - term transportation
SUMMARY In the present study calves were subjected to stressful conditions that occure during short - term transportation. In order to describe the influence of transport stress to lipid peroxidation
The influence of different doses of α-tocopherol and ascorbic acid on selected oxidative stress parameters in in vitro culture of leukocytes isolated from transported calves.
Abstract The objective of the study was to assess in vitro the influence of various doses of two different antioxidants, α-tocopherol and ascorbic acid, on protective mechanisms against ROS in white
An evaluation of the effects of α-tocopherol and ascorbic acid in bovine respiratory disease complex occurring in feedlot calves after transport
Evaluating the effects of vitamins E and C on the development of the inflammation process and on selected defence mechanisms against infections induced by M. haemolytica found no differences in the percentage of cells sensitive to Lkt between the group given vitamin E and the calves which received vitamin C.
Bacteriophage therapy to combat bacterial infections in poultry
The progressive increase in the number of multi-drug resistant bacteria and the complete ban on the use of antibiotics in livestock feed in the EU, as well as the partial ban in the US, have led to the growth of research on theUse of bacteriophages to combat bacterial infections in humans and animals.
16S-ARDRA and MALDI-TOF mass spectrometry as tools for identification of Lactobacillus bacteria isolated from poultry
The MALDI-TOF MS and 16S-ARDRA assays are valuable tools for the identification of avian lactobacilli to the species level and can be used for discrimination of Lactobacillus bacteria from different habitats.
Characterization of heat-shock proteins in Escherichia coli strains under thermal stress in vitro.
The presence of very strong protective adaptation in the bacteria in unfavourable conditions, which is critical for the organism infected by them, is indicated by the localization of Hsps in cell fractions.
Conglutinin, CL-43 and CL-46--three bovine collectins.
Northern blot or immunocytochemical analysis confirm biosynthesis of bovine collectins mainly in the liver (conglutinin, CL-43) and in the thymus (CL-46) and show antiviral activities towards influenza A virus and rotaviruses and protective activity against bacterial infections.
Assessment of antibiotic susceptibility in Lactobacillus isolates from chickens
The findings indicate that intestinal lactobacilli should be considered a reservoir of resistance genes and that antibiotics must be used prudently in poultry production.
