introduction: tuberculosis (tb) remains a deadly infectious disease despite all the efforts to reduce its incidence. spread of multidrug resistant tb has seriously undermined the efforts to control the disease globally. in this study protein expression profile of mdr and sensitive isolates of mtb were analyzed and compared in order to identify proteins, which could be used in prevention, diagno...

Seed proteins of eight species of the genus Suaeda (Chenopodiaceae) were compared by means of polyacrylamide disc gel electrophoresis. Different samples of the same species showed not less than 89% similarities, and geographical separation had no remarkable effect on seed protein patterns of the same species. Morphological heterogenity, that creates difficulties in infrageneric classificat...

background: dicrocoelium dendriticum, a liver trematode of herbivores, and man is very prevalent among ruminants of iran, resulting in causing significant economic losses. recently its phenotype polymorphism has been found in iran, a phenomenon that may affect the protein profile of the parasite. objectives: the aim of this study was to determine the somatic protein profiles of d.dendriticum in...

Antiviral proteins (AVP), present in silkworm fecal matter, show activity against nuclear polyhedrosis virus (NPV) in vitro and in vivo. The extract of silkworm fecal matter prepared in phosphate buffer solution of pH 7.5 was subjected to 50% solid ammonium sulfate precipitation to enrich AVP, then which was dialyzed. The dialysate was applied to the column containing silica gel-G, the column e...

oestrus ovis is an economically important parasite of small ruminants and a zoonotic parasite with many reports of ophthalmomyiasis in human from iran and other countries. the aim of the peresent studywas the isolation and identification of excretory-secretory (es) and somatic (s) antigens of o. ovis second and third stage larvae (l2, l3) collected from arabi sheep breeds located in southwest o...
