Introduction: The novel coronavirus disease 2019 (COVID-19) has huge impact on public health. RT-PCR of respiratory samples is generally accepted confirmatory test which can miss several cases due to various factors. Case description: A 32-years-old male without any co-morbidity presented with complaints cough and fever was negative for Reverse Transcription Polymerase Chain Reaction (RT-PCR) t...
Background: This study aimed to evaluate the diagnostic value of outer dense fiber 4 (ODF4), melanoma-associated antigen A3 (MAGEA3), and MAGEAB4 mRNAs in transitional cell carcinoma (TCC), using a small amount of cell reverse transcriptase-polymerase chain reaction (RT-PCR) on urinary exfoliated cells. Methods: We recruited a total of 105 suspected TCC patients and 54 sex- and age-matched non-...
Canine distemper virus (CDV) is the cause of canine distemper (CD) which is a severe and highly contagious disease in dogs. In the present study, a duplex reverse transcription polymerase chain reaction (RT-PCR) method was developed for the detection and differentiation of wild-type and vaccine strains of CDV. Four primers were designed to detect and discriminate the two viruses by generating 6...
Background and Aims: Influenza virus is a major pathogen involved in respiratory illnesses during winter seasons. A variety of diagnostic methods have been developed to identify influenza viruses in clinical specimen. Methods: Nasal and pharyngeal samples taken from patients were inoculated into Madin-Darby canine kidney (MOCK) cells and embryonated chicken eggs (ECEs). The culture media was a...
Background: Sinonasal symptoms were usually reported to appear initially, yielding the important for early detection of coronavirus disease 2019 (COVID-19). This study was conducted retrospectively investigate detailed sinonasal manifestations and dynamic profile real-time reverse transcription polymerase chain reaction (RT-PCR) results severe acute respiratory syndrome 2 (SARS-CoV-2) in COVID-...
A real-time reverse transcription-polymerase chain reaction (RT-PCR) assay was developed to rapidly detect the severe acute respiratory syndrome-associated coronavirus (SARS-CoV). The assay, based on multiple primer and probe sets located in different regions of the SARS-CoV genome, could discriminate SARS-CoV from other human and animal coronaviruses with a potential detection limit of <10 gen...
DNA products generated from a region of the measles virus genome by three RNA reverse transcription and amplification methods were cloned and sequenced, and the results were compared in order to evaluate the methods' relative fidelities. The methods were: (i) reverse transcription followed by a nested polymerase chain reaction (RT-nPCR), (ii) a combined RT-PCR using rTth polymerase and (iii) nu...
Background and Aims: Canine distemper (CD) is a deadly infectious disease of Canidae family. CD is a multi-systemic viral disease and is specified by wide range of clinical symptoms. The manifestations are not always indicative of CD, therefore a laboratory confirmation is necessary for suspected cases. Materials and Methods: Different clinical specimens of 19 CD suspected unvaccinated dogs wer...
