In many species benzoate is conjugated in the liver with glycine to form hippurate, after prior formation of benzoyl-CoA, which then reacts with glycine in a transacylation catalysed by glycine N-acylase (EC 2.3.1.13) (Bridges et al., 1970). This enzyme has been prepared from mitochondria (Schachter & Taggart, 1954; Bartlett & Gompertz, 1974), although there is no information about its submitoc...

background : ascaridia galli , the largest nematode of small intestine of birds, especially the native poultry, may give rise to serious illness, pathological defects and economical losses even in modern poultry production systems. although various measures have been undertaken to vaccinate poultry against a.galli , no satisfactory results were obtained so far. however, there is no report on th...

Background and Aims: Prevention of Lumpy skin disease (LSD) in cattle is heavily dependent on vaccination. Since the genetic structure of LSD virus has the close relatedness with other Capri-pox virus (CaPV). Therefore, the use of vaccine strains of CaPV derived from sheep and goat would be useful to protect cattle against LSD. Materials and Methods: The susceptible calves of dairy farms were ...

Activity of S-adenosylmethionine-dependent arginine methyltransferase was substantially higher in sonicated bone marrow samples from 6 patients with chronic erythremic myelosis than in bone marrow from 3 patients with untreated pernicious anemia, 2 patients with autoimmune hemolytic anemia, and 4 normal persons. Increased activity of this enzyme may be one of the factors contributing to the pat...

In the present study the effect of the locally produced genetic adjuvant of ginea pig specific CpG-motif-containing oligodeoxynucleotide (CpG-ODN) in an inactivated FMD virus vaccine was evaluated. Boosting the ginea pigs with FMD vaccine along with CpG-ODN adjuvant produced relatively higher ratio (5-fold) of FMDV-specific IgG2a / IgG1 than those vaccinated in the absence of CpG-ODN. The neutr...

newcastle disease (nd) is one of the most serious illnesses of chickens. live vaccines are widely used to prevent chicken from the disease all over the world. to access the effective and potentiate nd vaccine, a homogenous subpopulation from lasota strain was selected following cultivation of the virus on primary chicken embryofibroblast (cef) cells. pathogenicity indices and molecular characte...
