The ethiological factor of periodontal diseases is the presence periodontopathogens; in state imbalance with commensals they begin to affect pathologically. With a decrease number periodontopathogens biofilm, it possible restore balance and prevent or their transition stage remission. Nowadays, most informative accessible diagnostic method for determining real-time polymerase chain reaction (PC...

introduction and aims: the role of human papillomavirus (hpv) in the etiology of esophageal squamous cell carcinoma (escc) is not clear. previous studies have found highly variable (from 0% to 67%) prevalence of hpv in escc tumor. however, prevalence of hpv in escc tumor seems to be higher in areas with high incidence of escc , such as china and south africa. iran is one of the areas of the wor...

conclusions the observed results indicated the necessity of good care in abattoir, butcheries and during food distribution, mainly ground beef. also, a zero tolerance policy could be useful to control e. coli o157 in meat products nationwide. results overall, 1.5% of ground beef samples were contaminated with the o157 e. coli strain meanwhile 1% of samples contained the o157:h7 strain and 0.5% ...

PCR: polymerase chain reaction TMP-SMX: trimethoprim-sulfamethoxazole XLA: X-linked agammaglobulinemia INTRODUCTION Helicobacter cinaedi is an unusual cause of cellulitis in immunocompromised patients. The organism is fastidious, and blood cultures are often negative, making the diagnosis challenging, especially in those without systemic signs. We report a case of chronic H cinaedi cellulitis i...

Enzyme immunoassay and polymerase chain reaction have become the «gold standard» for detection of biological pathogens. The method amplified – immuno-PCR allows to combine both methods into a single platform preserve their advantages achieve high sensitivity analysis. purpose this work is consider possibilities prospects using PCR-amplified pathogenic agents. Immuno-PCR makes it possible detect...
