leptospirosis is one of the most prevalent zoonotic diseases worldwide. currently, multivalent whole-cell leptospiral vaccines can induce protection against leptospirosis. therefore, preparation and formulation of new generations of vaccines that can stimulate long-term immunity for leptospirosis control are essential. the aim of this study was to prepare and characterize alginate microspheres ...
the liver fluke fasciola hepatica causes fascioliasis, a liver disease in most part of the world and particularly in north of iran. diagnosis of the diseases is anchored in coprological manner but serological methods are preferable due to some obscurities. in this study, sera obtained from human patients infected with fasciola hepatica were tested by the enzymelinked immunotrotransfer blot (eit...
The effects of tyrosine kinase inhibitors (TKIs) were evaluated on growth inhibition of intracellular Toxoplasma gondii in host ARPE-19 cells. The number of tachyzoites per parasitophorous vacuolar membrane (PVM) was counted after treatment with TKIs. T. gondii protein expression was assessed by western blot. Immunofluorescence assay was performed using Programmed Cell Death 4 (PDCD4) and T. go...
We have generated recombinant adenoviruses encoding three genetically modified surface antigens (SAGs) of the parasite Toxoplasma gondii, that is, AdSAG1, AdSAG2, and AdSAG3. Modifications included the removal of their glycosylphosphatidylinositol (GPI) anchoring motifs and, in some cases, the exchange of the native signal peptide for influenza virus hemagglutinin signal sequence. Adenovirus im...
Toxoplasma gondii can infect nearly all warm-blooded animals. We report an acute fatal T. gondii infection in the endangered giant panda (Ailuropoda melanoleuca) in a zoo in China, characterized by acute gastroenteritis and respiratory symptoms. T. gondii infection was confirmed by immunological and molecular methods. Multilocus nested PCR-RFLP revealed clonal type I at the SAG1 and c29-2 loci,...
To develop a multiple antigenic peptide (MAP) vaccine against toxoplasmosis, tri-epitope MAP constructs were made in dimeric fashion. The constructs included one B-cell and two T-cell epitopes derived from Toxoplasma gondii antigens (SAG1, GRA4 and GRA1) situated in tandem through the GGG spacer sequence, with the latter positioned adjacent to a polylysine core. Immunization of BALB/c and Kunmi...
Toxoplasma gondii atypical type II genotype was diagnosed in a pet peach-faced lovebird (Agapornis roseicollis) based on histopathology, immunohistochemistry, and multilocus DNA typing. The bird presented with severe neurological signs, and hematology was suggestive of chronic granulomatous disease. Gross post-mortem examination revealed cerebral hemorrhage, splenomegaly, hepatitis, and thicken...
