The purpose of this study was to evaluate the transmission of pathogenic respiratory bacteria to thirteen 5-month-old specific pathogen free (SPF) pigs, during the slaughtering process in a commercial slaughterhouse. Before transportation, the SPF pigs and the lorry were checked to confirm the absence of pathogenic respiratory bacteria. Nine SPF pigs (group 1) were in contact in a conventional ...
در این مطالعه بیماریزایی عفونت همزمان ویروس a/chicken/iran/m.1/2010) h9n2)و باکتری اورنیتوباکتریوم رینوتراکئال (ort- r87-7/1387) و تمایل این عفونت به بافت های مختلف و همچنین انتشار آن در بدن جوجه های نژاد لگهورن spf موردبررسی قرار گرفت. همچنین علایم بالینی و ضایعات کالبدگشایی در پرندگان مبتلا ارزیابی شد. چهل قطعه جوجه تفریخ شده از تخم مرغ جنین دار spf در سن 21 روزگی به صورت تصادفی به دو گروه ت...
The persistent public health threat of animal to human transmission of influenza A virus (IAV) has stimulated interest in rapid and accurate detection of all IAV subtypes in clinical specimens of animal origin. In this study, a new set of primers and probes was designed for one-step pan-IAV reverse-transcription fluorescence resonance energy transfer (FRET)-PCR. The detection limit of one-step ...
The distribution of the immune complex vaccine virus for infectious bursal disease (IBD) in tissue was examined and the viral loads of the organs were quantitatively compared. One-day-old specific pathogen free (SPF) and maternally immune broiler chickens were injected subcutaneously with the vaccine. Lymphoid and non-lymphoid tissues were collected at various time intervals during the experime...

the invention of polymerase chain reaction (pcr) has been a milestone in the history of biological and medical sciences. the applications of pcr have not only completely revolutionised the research in the field of molecular genetics as well as animal and plant biotechnology, but the technique has also proved its relevance and ingenious utility in other fields of forensic sciences, molecular sys...
We compared two consensus primer PCR human papillomavirus (HPV) genotyping methods for the detection of individual HPV genotypes and carcinogenic HPV genotypes as a group, using a stratified sample of enrollment cervical specimens from sexually active women participating in the NCI/Costa Rica HPV16/18 Vaccine Efficacy Trial. For the SPF(10) method, DNA was extracted from 0.1% of the cervical sp...
