Avian metapneumovirus (aMPV) represents one of the most prevalent diseases of poultry mainly in combination with other pathogens, and it is increasing among chickens. In the present study, the detection and characterization of an aMPV subtype B strain circulating in broiler flocks based on fusion (F) gene. In phylogenetic analysis, the isolates are located in B subtype cl...
Objective(s): Listeria monocytogens, Bacillus cereus and Campylobacter jejuni are three toxin producing bacteria over the world, especially in Iran, and it is essential to find a certain, rapid procedure to identify these microorganisms. In this research, these bacteria were simultaneously detected by multiplex PCR technique in foods. Materials and Methods: The primary approval of bacterial str...
Background and purpose: Staphylococcus aureus (S. aureus) produces various toxins. One of the most important toxins is enterotoxin. Enterotoxin A and B play a major role in food poisoning. This research was conducted to determine the enterotoxin A and B genes in S. aureus strains. Materials and methods: In this study, 223 specimens were collected from the skin and nose of patients, medical ...
a polymerase chain reaction-restriction fragment length polymorphism (pcr-rflp) test was performed to investigate the allele frequencies of the insulin-like growth factor (igf1 and igf2 genes) in 90 broilerchickens. a 793 bp fragment of igf1 gene and 1146 bp fragment of igf2 gene were amplified and digested with hinfi and hsp92ii restriction enzymes,respectively. two types of alleles of a and b...
Calpastatin (CAST) is a specific inhibiter of Calpains, playing a role in meat tenderization and myogenesis. In the present study the polymorphism of the CAST gene ofKhalkhali goat in Azerbaijan province in Iran was investigated by polymerase chain reaction and restriction fragment length polymorphism technique (PCR-RFLP). Genomic DNA was extracted from whole blood samples collected from 200 Kh...
Veritable identification and differentiation of avian species is a vital step in conservative, taxonomic, forensic, legal and other ornithological interventions. Therefore, this study involved the application of molecular approach to identify some avian species i.e. Chicken (Gallus gallus), Muskovy duck (Cairina moschata), Japanese quail (Coturnix japonica), Laughing dove (Streptopelia senegale...
Lymphomas are solid tumors of immune system and Non-Hodgkin Lymphomas (NHL) is the most prevalent lymphomas; with wide ranges of histological and clinical features, it is so difficult to identify them. Herein, various bioinformatics tools (such as gene differential expressions, epigenetics and protein analysis) employed to find new treatment approach for NHL based on gene expression variation b...
Background and Aim: In addition to exposure to Mycobacterium tuberculosis (MTB), development of tuberculosis is influenced by environmental and host genetic factors, and clinical disease only occurs in less than 10% of the infected individuals. Vitamin D metabolism leads to activation of macrophages and restricts the intracellular growth of mycobacterium. This effect may be influenced by poly...
conclusions: premature stop codon in the s gene was observed in all countries with evaluable hbv genome sequences. co-existence of detectable hepatitis b surface antigen (hbsag) and s gene premature stop codon was inconsistent with other studies. investigations on yield truncated hbsag are suggested to determine if they can affect elisa hbsag results. background: we have previously reported on ...
