The development of a rhinovirus (RV)-RNA-specific reverse transcription (RT)-PCR assay is complicated by the close homology between the RV and enterovirus (EV) genomes in the highly conserved 5'-noncoding region, which is chosen for primer design in most RT-PCR assays. We have developed a sensitive, rapid, and RV-specific nested RT-PCR assay and have used it to test nasopharyngeal aspirates fro...
بیماری تیلریوز یکی از مشکلات مهم در عدم پیشرفت صنعت دامپروری در مناطق گرمسیری و نیمه گرمسیری جهان است.تیلریوز یکی از بیماری های مهم تک یاخته ای خونی منتقله از راه کنه می باشد که در گاو، گوسفند، بز و سایر نشخوارکنندگان وحشی گزارش شده است. تیلریا لستوکاردی و تیلریا اویس به عنوان عوامل ایجاد کننده تیلریوز گوسفندی در ایران شناخته شده اند اما به لحاظ اپیدمیولوژیک وضعیت این بیماری در ایران به خوبی شن...
Human rhinoviruses (HRVs) are positive-stranded RNA viruses belonging to the Enterovirus genus in the family of Picornaviridae. Identification of the specific strain in HRV disease has been difficult because the traditional serological method is insensitive, labor intensive, and cumbersome. With the fast progress in molecular biological technique, more sensitive and faster molecular methods hav...
We report a nested reverse transcription-polymerase chain reaction (RT-PCR) assay for hantavirus using primers selected to match high homology regions of hantavirus genomes detected from the whole blood of hantavirus cardiopulmonary syndrome (HCPS) patients from Brazil, also including the N gene nucleotide sequence of Araraquara virus. Hantavirus genomes were detected in eight out of nine blood...
We evaluated the use of an integrated cell culture-reverse transcription-PCR (ICC-RT-PCR) procedure coupled with nested PCR to detect human astroviruses, enteroviruses, and adenovirus types 40 and 41 in surface water samples that were collected and evaluated by using the Information Collection Rule (ICR) method. The results obtained with the ICC-RT-PCR-nested PCR method were compared to the res...
In view of the high circulation of migratory birds and the environmental and climatic conditions which favor the proliferation of arthropods, the Brazilian Pantanal is susceptible to circulation of arboviruses. However, the amount of data concerning arbovirus vectors in this area is scarce; therefore the aim of this study was to conduct a preliminary investigation of Culicidae species in the Nh...
