background: hydatidosis is one of the cosmopolitan parasitic zoonoses caused by the larval stage of echinococcus granulosus. diagnosis of hydatidosis is still an unresolved problem. serological tests using crude antigens for diagnosis of e. granulosus are sensi-tive, however their specificity are not satisfactory. therefore, who recommended spe-cific serological methods using specific antigens,...

heartworm infection is one of the most important parasitic diseases in dogs and an increasing number of cases are reported each year by necropsy in ahvaz. this study was conducted to determine the prevalence of dirofilaria immitisinfection and to investigate the risk factors related to heartworm disease in urban dogs in this area. blood samples were collected from 100 dogs from feb 2007 to feb ...

objective(s): the aim of this study was to estimate effects of hyperbaric (hb) treatment by determination of cd15s and cd11b leukocyte proinflammatory markers expression.  in addition, this study describes changes in cd77 and cd34 expression on rat endothelial cells in renal, pulmonary and cardiac tissue following exposure to hyperbaric pressure. materials and methods:expression of cd11b and cd...

capture elisa system was developed for diagnosis of visceral leishmaniasis (vl) using a monoclonal antibody raised against an antigen previously detected in the urine of vl patients. urine samples from confirmed vl cases from yemen, nepal, spain, sudan and brazil were tested in the capture elisa in comparison with urine samples from endemic and non-endemic areas along with urine samples from pa...

The Yersinia pestis pH 6 antigen was expressed by, and purified from, Escherichia coli containing cloned psa genes. By an enzyme-linked immunosorbence-based assay, purified pH 6 antigen bound to gangliotetraosylceramide (GM1A), gangliotriaosylceramide (GM2A), and lactosylceramide (LC) (designations follow the nomenclature of L. Svennerholm [J. Neurochem. 10:613-623, 1963]). Binding to GM1A, GM2...

Objective(s): An efficient vaccine against TB is an urgent need. TB peptides are safe candidate but they are weak immunogens and needs to be potentiated by adjuvant/delivery systems. The main purpose of the present study was to determine the potential of CHT based NPs containing ESAT-6 antigen of M. tuberculosis for inducing mucosal and systemic immune responses after intranasal and subcutaneou...
