background : immunological response of host and parasite play a key role in developing vaccination and immunization. the present study deals with the immune response and effecter mechanism, which was confirmed by migration inhibition factor (mif). methods : the present work was conducted in parasitological lab of postgraduate department of zoology, government holkar science college, indore (...
Background: Leishmania major (L.major) is a causative agent of leishmaniasis. The disease has now become a public health problem. Modulation of the immune responses to inhibit the infection or the proliferation of the parasite is an effective way to overcome the leishmaniosis. Leishmania parasite secretory-excretory antigens are responsible for immune system modulation; therefore, they are u...
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: ornithobilharziosis as one of the parasitic infections may give rise to serious economic problems in animal husbandry. the aim of the study was to prepare and compare the somatic and excretory-secretory (es) antigens of o. turkestanicum in gel diffusion test. methods: excretory-secretory (es) and somatic antigens of ornithobilharzia turkestanicum were prepared from collected worms ...
fasciolosis diagnosis, due to low sensitivity of coprological diagnostic method has been challenging for a long period. in this study, dot-elisa, one of the simplest and the most sensitive tests in this regard, was evaluated using excretory-secretory antigens of fasciola hepatica to diagnose human fasciolosis three groups consisting of patients infected with fasciolosis (n= 95), patients with o...
purification of parasitic antigens is a major activity in immunoparasitology because of its application in immunodiagnosis, vaccination analysis of immunopathology, preparation of monocolomal antibody and finding out the cross reactive antigens versus specific antigens of a parasite. in this survey f2 ultrafiltration excretory secretory antigens of ascaris lumbricoides and toxocara cati were se...
Background: Fasciolosis is a worldwide disease with major economic and public health consequences. Early detection of the infection is important for the prevention and control of the disease. ELISA allows for early detection of fasciolosis in man and animals. Fasciolosis is caused by Fasciola hepatica and F. gigantica in man and domestic animals respectively. These two species have many similar...
BACKGROUND: Toxocara canis is the most prevalent intestinal roundworm of canid species. OBJECTIVES: This study aims to evaluate the effects of Toxocara canis excretory-secretory antigens (TcES Ag) on modulating the immune system in Experimental Allergic Encephalomyelitis (EAE) model. METHODS: Adult worms of T.canis were collected from dogs to obtain excretory-secretory antigens. Female C57BL/6m...
Background and purpose: One of the transmission ways of the congenital toxoplasmosis is through the placenta to the fetus, therefore, its diagnosis at early stage is very important. Toxoplasma gondii parasite contains various antigens of which excretory-secretory antigens (E/SA) are used in designing Elisa avidity kit. The aim of this study was to compare the results of commercial kit and desig...
Toxoplasma gondii is an obligatory intracellular protozoan that infects all warm-blooded vertebrates. Almost one-third of people throughout the world are infected by this parasite. Although toxoplasmosis is often lethal in HIV/AIDS patients, neoplastic disease, bone marrow or heart transplant recipients, it results in life-long protective immunity in healthy people. Hence, different antigens of...
