detection of mycoplasma synoviae (ms) by culture and polymerase chain reaction (pcr) has been reported from commercial chicken farms in different provinces of iran. in some reports the phylogenetic analysis of ms isolates based on 16s rrna and variable lipoprotein hemagglutinin (vlha) genes have been carried out. the pcr product containing partial 16s rrna genes of iranain isolates was sequence...
infection by toxoplasma gondii is widespread inhumans and many other species of warm-blooded animals. it can cause significant morbidity and mortality in the developing fetus and in immunocompromised individuals,including humans with acquired immunodeficiency syndrome (aids) or submitted to cancer chemotherapy.among livestock, sheep and goat are more widely infected with t. gondii. this parasit...
conclusions our study demonstrated that the b1 gene, more so than the re gene, showed positive samples and can be used to detect toxoplasmosis, although the b1 gene, in comparison to the re gene, did not show any superiority of molecular diagnosing capability. results also showed that toxoplasma molecular detection methods can be used instead of routine serological detection methods in a clinic...
Aflatoxin B1-contaminated feeds and foods induce various health problems in domesticated animals humans, including tumor development hepatotoxicity. B1 also has embryotoxic effects different livestock species humans. However, it is difficult to distinguish between the indirect, maternally-mediated toxic direct embryotoxicity of aflatoxin mammals. In present study, we investigated B1-induced a z...
more than 185 species, strains and unclassified theileria parasites are categorized in the entrez taxonomy. the accurate diagnosis and proper identification of the causative agents are important for understanding the epidemiology, prevention and appropriate treatment. this study aims to discuss the importance of two genes of theileria annulata 18s ribosomal rna (18s rrna) and theileria annulata...
Background and Aims: Many bacteria including Escherichia coli may enter into a viable but non-culturable (VBNC) state under unfavorable stresses, which are unable to be detected by culture-based methods. In this study, the use of Reverse Transcription PCR (RT-PCR) for detection of VBNC state of E. coli O157:H7 was investigated. Materials and Methods: Escherichia. coli O157:H7 was inoculated i...
In this study, to increase information about the relationship between caprine and ovine isolates of Pasteurella multocida, 16S rRNA gene sequencing of 9 goats (5) and sheep (4) isolates were investigated. Also, capsular type and toxAgene presentation was studied in this paper. All isolates, except one, belong to capsular type A, and toxA+ strain distributed among strains were isolated from both...
one hundred and fifty blood samples were prepared from cattle of a region in isfahan. the extracted dna from blood cells were analyzed by a. centrale (amori strain) specific nested-pcr using primers derived from 16s rrna gene. all blood smears were negative for a. centrale like structures. the results showed that 2 of total 150 blood samples (1.33%) were a. centrale (amori strain) positive by s...
Studies on earthworms using molecular markers are rare in Africa except a handful from South Africa. Reports on Libyodrilus violaceous,an earthworm found in West Africaare available including their metal tolerance and bioaccumulation capacity but their molecular characterization and ecotoxicology studies are scarce. In this study, triplicate L. violaceous specimens were collec...
