Staphylococcus aureus carrying PVL gene remain major health problem associated with highly virulent infections. Characterization of such gene is important to know the impact and the functional significance of nucleotide variations. PCR and standard sequencing were performed for twelve Sudanese strains from different sources. Protein structures prediction, modeling and physiochemical analysis we...

objective: survey of molecular characterization of nucleoprotein gene of h9n2 avian influenza viruses and determination of the genetic relationship of iranian h9n2 viruses and other asian viruses. materials and methods: the nucleoprotein (np) genes from 4 isolates of h9n2 viruses isolated from commercial chickens in iran during 2008-2009 were amplified by rt-pcr method and sequenced. nucleotid...

dialysis and non-dialysis group were comparable for age and sex and whether the apparent differences in small numbers of patients was statistically significant. We studied the immediate effect of dialysis and found no significant difference in the peak acid output measured in the same 14 patients before and after dialysis,2 but on reviewing our data we find that the basal acid output was signif...

The Bacteriological Code contains Principles and Rules governing the naming of prokaryotic taxa. However, interpretation of the Code is not always easy, nor is the dynamic link between the names of taxa and a particular taxonomic opinion always fully appreciated.

coloured plates 83. Price 15s. net. This work is intended for use in conjunction with a textbook on Bacteriology and Parasitology. The present edition includes twenty-six new coloured plates by Dr. van Rooyen, in addition to the illustrations contained in the first edition. Perhaps the most admirable feature of the atlas is that it is comprehensive and yet compact. The excellent illustrations s...

The objective of this paper focused on the ffects of dietary nucleotides (NT) on histopathological alternations of striped catfish Pangasianodon hypophthalmus, after exposure to water-borne silver nanoparticles (AgNPs) and silver nitrate (AgNO3). Fish were fed with a diet containing nucleotide (0.75%) or control diet for 10 weeks and then divided into 3 experiments including control, 20 µ...

BACKGROUND Ciprofloxacin, ceftriaxone and pivmecillinam are the antibiotics currently recommended by the World Health Organization (WHO) for the treatment of dysentery in children; yet there have been no reviews of the clinical effectiveness of these antibiotics in recent years. METHODS We reviewed all literature reporting the effect of ciprofloxacin, ceftriaxone and pivmecillinam for the tre...

Listeriosis is a sporadic disease of ruminants that causes meningoencephalitis, septicemia and abortion. In this study, the usefulness of immunoperoxidase technique was investigated in early diagnosis of cattle listerial abortions. For this purpose, 96 smears prepared from vaginal swab samples that were collected from aborting cattle were stained for L. monocytogenes by immunoperoxidase techniq...

Streptococcus (S.) dysgalactiae subsp. equisimilis is responsible for severe diseases in humans, including primary bacteraemia, pneumonia, endocarditis, and toxic shock syndrome. Infection in some animal species can also occur, although a few studies have looked into cross-species infectivity. In horses, S. equisimilis is generally considered infrequent or opportunistic, but has recently been i...
