Development of Multiplex PCR Assays for the Identification of the 33 Serotypes of Streptococcus suis
Streptococcussuis is an important zoonotic agent causing severe diseases in pigs and humans. To date, 33 serotypes of S. suis have been identified based on antigenic differences in the capsular polysaccharide. The capsular polysaccharide synthesis (cps) locus encodes proteins/enzymes that are responsible for capsular production and variation in the capsule structures are the basis of S. suis se...
Colibacillosis caused by Escherichia coli infections account for significant morbidity and mortality in the poultry industry. Yet, despite the importance of colibacillosis, much about the virulence mechanisms employed by avian E. coli remains unknown. In recent years several genes have been linked to avian E. coli virulence, many of which reside on a large transmissible plasmid. In the present ...
Although alpha-thalassemia is the most common genetic abnormality in the world, there is currently no routine laboratory method to definitively identify individuals who are affected. We describe a rapid and simple method that utilizes deletion-sensitive primers to amplify normal DNA sequences. Deletions involving the regions responsible for most of the alpha-thalassemia cases in the US prevent ...
Three sets of oligonucleotide primers were used in the polymerase chain reaction (PCR) assay to detect Salmonella species. phoP primers specific to the phoP/phoQ loci of coliform pathogenic bacteria such as Salmonella, Shigella, Escherichia coli, and Citrobacter species served as presumptive indicators of enteric bacteria. In addition to the phoP primers, the Hin and the H-1i primers, which tar...
Two molecular biology methods were used to differentiate Salmonella enterica 1,4,[5],12:i:- strains: "Salmonella Check&Trace microarray" (CT) and multiplex PCR (mPCR). For 92 strains in CT result "Salmonella 1,4,[5],12:i:-" were obtained. Those strains were confirmed in mPCR as monophasic fljB-lack Salmonella Typhimurium. For 17 strains, which in CT assay were recognized as Salmonella Typhimuri...
زمینه و هدف: کلامیدیا تراکوماتیس شایع ترین عفونت مقاربتی باکتریایی در جهان است، اما اثر این عفونت بر باروری مردان هم چنان مورد بحث می باشد. با وجود گزارشاتی مبنی بر میان کنش مایکوپلاسما ژنیتالیوم و اسپرم، این پاتوژن نیز در نمونه منی افراد نابارور کم تر مطالعه شده است. در این مطالعه فراوانی عفونت کلامیدیا تراکوماتیس و مایکوپلاسما ژنیتالیوم در مردان نابارور مورد بررسی قرار گرفت.روش بررسی: از میان...
Background and Aims: A multiplex transcription-polymerase chain reaction (m-PCR) was developed for direct detection and discrimination between canarypox virus (CPV) and other avian poxvirus (APV). Materials and Methods: Three compatible primer sets were designed for m-PCR amplification of different loci fpv126, fpv140, and fpv167 located at highly conserved APV genes. Results: Results showed th...
بیماری¬های ویروسی ناشی از نپوویروس¬ها از مخرب¬ترین بیماری¬های ویروسی مو در سراسر جهان به حساب می¬آیند که با نماتدهای خانواده longidoridae منتقل می¬شوند. اغلب این ویروس¬ها دارای میزبان¬های طبیعی متعددی در بین گیاهان زینتی و غیر زینتی، درختان میوه و علف¬های هرز می¬باشند. پیکره اعضای این جنس دو بخشی، جورقطر و به قطر حدود 30 نانومتر می¬باشد. غلظت این ویروس¬ها در گیاه و به ویژه تاک پایین است و در نت...
Human herpesvirus 6 (HHV-6) can integrate its genome in human chromosomes and be germline transmitted (inherited chromosomally integrated HHV-6). We report a case of HHV-6 inherited from the mother unexpectedly diagnosed septic neonate. Since has recently been included multiplex polymerase chain reaction assays for meningitis/encephalitis, diagnosing status is essential to avoid misdiagnosis ac...
