The aim of this study was to develop a PCR for the diagnosis of Fasciola hepatica infection in feces of sheep based on the ribosomal internal transcribed spacer. Detection of infection was possible from the second week post-infection in experimentally infected sheep by amplification of a 292bp fragment. This PCR was employed for the detection of anthelmintic resistance (AR) in naturally infecte...
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 protective role of Sickle Cell Trait (SCT) in malaria endemic areas has been proved, and prevalence of HbS gene in malaria endemic areas is high. Splenic infarction is a well-known complication of SCT, while the association with malaria is considered rare. A Nigerian boy was admitted to our ward after returning from his country of origin, for P. falciparum malaria. He underwent abdominal ul...
Cells of the VSR751 strain, which was previously isolated as a photoresistant revertant of the visA-deleted (hemH-deleted) strain of Escherichia coli K-12, accumulated uroporphyrin (uro), coproporphyrin (copro) and protoporphyrin IX (proto), but did not accumulate as much protoporphyrin as cells of the parental strain (hemH-deleted). Therefore, we concluded that strain VSR751 must be defective ...
The zoonotic potential of Cryptosporidium was studied in one of the most densely populated provinces of Egypt regarding livestock and people. In a representative survey, faecal samples from cattle, buffalo and stool samples from diarrhoeic children (<10 years) were investigated. Parameters assumed to be related to cryptosporidiosis were recorded for animals and children. Animal samples (804) we...
the protective capacity of the crude extracts from larval and nymphal stages of hyalomma anatolicum anatolicum was examined in the new zealand white rabbits. the rabbits were randomly divided into 3 groups of five animals. the rabbits in groups 1 and 2 were immunized with crude extracts of larval and nymphal antigens, respectively and group 3 was served as control. following challenge of each r...
the features of helicobacter pylori adhesins, their interactions with their host counterparts, regulated and selective gene expressions are amongst the many clever strategies this microorganism undertakes to survive the otherwise sterile gastric milieu. the ingenious crafting of these interactions and the respective host reactions govern, in part, an array of consequences ranging from asymptoma...
