مقدمه: بیماری هپاتیت A بوسیله ویروس هپاتیت A ایجاد می‌شود و از راه مدفوعی-دهانی منتقل می‌شود و سبب ایمنی مادام‌العمر همراه است. این بیماری شیوع نسبتاً بالایی در کشورهای در حال توسعه دارد، به طوری که بیشتر افراد در سنین کودکی به آن مبتلا می‌شوند. در نتیجه امروزه سرولوژی این بیماری در بزرگسالان کاهش یافته است. این مطالعه جهت بررسی آنتی بادی هپاتیت A (HAV IgG Anti) در کارکنان بالغ شاغل در بیمارس...
Rubella serum assays performed in the laboratory of the Materno-Infantil Presidente Vargas Hospital (HMIPV) from 1998 to 2002 were reviewed to determine if IgG avidity assays should be implemented. IgG was determined using the Enzyme Linked Fluorescent Assay, ELFA, VIDAS system, bioMerieux or the Microparticle Enzyme Immunoassay, MEIA, Axsym system, Abbott, and IgM was determined using the ELFA...
BACKGROUND & AIMS Since 2009/10, a 10- and a 13-valent pneumococcal conjugate vaccine (PCV) are available, but only the 10-valent vaccine is now being used for the children in the Netherlands. As the vaccines differ in number of serotypes, antigen concentration, and carrier proteins this study was designed to directly compare quantity and quality of the antibody responses induced by PCV10 and P...
Diagnostic Methods for and Clinical Pictures of Polyomavirus Primary Infections in Children, Finland
We used comprehensive serodiagnostic methods (IgM, IgG, and IgG avidity) and PCR to study Merkel cell polyomavirus and trichodysplasia spinulosa-associated polyomavirus infections in children observed from infancy to adolescence. Comparing seroconversion intervals with previous and subsequent intervals, we found that primary infections with these 2 viruses were asymptomatic in childhood.
In the United States, approximately 9% of the measles cases reported from 2012 to 2014 occurred in vaccinated individuals. Laboratory confirmation of measles in vaccinated individuals is challenging since IgM assays can give inconclusive results. Although a positive reverse transcription (RT)-PCR assay result from an appropriately timed specimen can provide confirmation, negative results may no...
Cytomegalovirus (CMV) seroprevalence among U.S. children 1 to 5 years old was assessed in the National Health and Nutrition Examination Survey of 2011 to 2012. The overall seroprevalence (95% confidence interval) of IgG was 20.7% (14.4 to 28.2%), that of IgM was 1.1% (0.4 to 2.4%), and that of low IgG avidity was 3.6% (1.7 to 6.6%), corresponding to a 17.3% (10.1 to 26.7%) prevalence of recent ...
A cross-sectional study was conducted to determine the seroepidemiology of Toxoplasma infection and its risk association among people having close contact with animals. A total of 312 blood samples were collected from veterinary personnel (veterinarian, technicians, and students) and pet owners from veterinary clinics and hospitals in the area of Klang Valley, Malaysia. About 4 cc of blood samp...
