The aim of this study was to test the potential diagnostic usefulness of recombinant Toxoplasma gondii rhoptry antigens, ROP2 and ROP4, with respect to toxoplasmosis detection and infection phase distinction in laboratory mouce by determining specific serum IgM and IgG antibodies with the use of indirect ELISA technique. The mice antibody response to ROP(More)
Toxoplasmosis is one of the most common parasitic infections worldwide. An effective vaccine against human and animal toxoplasmosis is still needed to control this parasitosis. The polymorphic rhoptry proteins, ROP5 and ROP18, secreted by Toxoplasma gondii during the invasion of the host cell have been recently considered as promising vaccine antigens, as(More)
Inter-individual variation in immune response to widely used prophylactic vaccines against infectious diseases is strongly influenced by sex, MHC (Major Histocompatibility Complex), age and current hormones status of vaccinated individuals. Numerous findings showed that microorganisms residing at different sites of human or animal body (natural microbiota),(More)
The article presents selected data concerning pathogenesis, clinical manifestations, natural and specific resistance and vaccines against T. gondii infections. Toxoplasma gondii protozoan has been recognized as one of the most successful parasites infecting any nucleated cell of human individuals and most warm-blooded animals. The infection causes(More)
One of the most characteristic features of many intracellular parasite infections is their chronicity indicating that the host immune system is not capable of eradicating the pathogen. Toxoplasma gondii is the most successful parasite worldwide, infecting an extraordinarily broad range of hosts (endothermic animals and humans) and almost all cell types.(More)
End-point-attached heparinized polyethylene (H-PE) was implanted for 2 months into the peritoneum of C57B1/6 mice. The proliferation of bone marrow cells (BMCs) from implanted and non-implanted mice was investigated in M-CSF supplemented medium, in the presence or absence of macrophage-specific monoclonal antibodies (mAbs). The mAb HC 7.67.B, recognizing a(More)
Macrophage-mediated early nonspecific immunological response is an important part of the immunity against intracellular parasite Toxoplasma gondii. The immunological functions of macrophages are closely connected with iron metabolism and acquiring of iron mainly from transferrin by the receptor-mediated endocytosis. The level of specific transferrin(More)
Toxoplasma gondii, the etiological agent of toxoplasmosis, is an Apicomplexa obligate intracellular protozoan parasite, which is able to infect any nucleated cell of numerous endothermic vertebrates. The combined abilities to actively penetrate host cells and perfectly control the fate of the parasite-containing vacuole (parasitophorus vacuole, PV)(More)
