Brucella is an intracellular pathogen capable of infecting animals and humans. The aim of this study was to identify Brucella spp in sera of high risk individuals by a polymerase chain reaction (PCR)-based method. A total of 180 patients suspected to have Brucellosis were examined by serological tests. To establish a PCR protocol for diagnosis of active brucellosis, DNA was extracted from the s...

In this article, the development of a new TaqMan-based one-step real-time reverse transcriptase-polymerase chain reaction (RT-PCR) assay for detection and quantification of Crimean-Congo hemorrhagic fever virus (CCHFV) RNA is described. Selected oligos targeting the highly conserved S region of CCHFV were designed by using our oligo design and analysis software, Oligoware 1.0. None of the prime...

Phylogenetic and "fingerprinting" analyses of the 16S rRNA genes of prokaryotes have been a mainstay of microbial ecology during the last two decades. However, many methods and results from studies that rely on the 16S rRNA gene for detection and quantification of specific microbial taxa have seemingly received only cursory or even no validation. To directly examine the efficacy and specificity...

In the present research, molecular detection of bovine leukocyte adhesion deficiency (BLAD) and complex vertebral malformation (CVM)in a population of Iranian Holstein cows has been carried outusing milk somatic cells by polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP). The BLAD and CVM are monogenic and autosomal recessive heredity lethal syndrome in Holstein-Friesi...

objective: utility of pcr-rflp and species-specific pcr as novel and fast methods for identification and discrimination of causative agents of relapsing fever, borrelia persica and b. microtii in infected blood were investigated. materials and methods: genomic dna of b.persica and b.microtii species were extracted from the highly infected blood samples. two fragments of glpq and 16srdna genes ...

OBJECTIVES In order to develop a multiplex RT-PCR assay using the GeXP analyser for the simultaneous detection of four different NA serotypes of H5-subtype AIVs, effective to control and reduce H5 subtype of avian influenza outbreak. DESIGN Six pairs of primers were designed using conserved and specific sequences of the AIV subtypes H5, N1, N2, N6 and N8 in GenBank. Each gene-specific primer ...

background: visceral leishmaniasis (vl) or kala-azar is an important parasitic disease caused by protozoan parasites of the genus leishmania including l. donovani and l. infantum. some evidences show that vl is present in some areas of kermanshah province and this study aimed to characterize the causative agent of vl in this region. methods: bone marrow sample was obtained from 9 vl patients fr...

AIMS To evaluate three oligonucleotide primer pairs--two specific for 16S and 23S rRNA sequences of Burkholderia cepacia, and the third specific for internal transcribed spacer region of 16S-23S sequences of B gladioli--for the identification and differentiation of reference and clinical strains of these and other species. METHODS The three primers sets were applied in polymerase chain reacti...

Avibacterium paragallinarum is Gram-negative bacteria that cause infectious coryza (IC), an acute respiratory disease of chickens. Despite vaccination of Layer and breeder farms of Iran against IC, they are still experiencing the disease clinically and there is no knowledge of serotypes prevalence of this bacterium in this country. This study designed to determine serovar identity by molecular ...
