BACKGROUND Two important challenges to the use of serological assays for influenza surveillance include the substantial amount of experimental effort involved and the inherent noisiness of serological data. RESULTS I show that log-transformed serological data exist in an effectively one-dimensional space. I use this result, together with new mechanistic insights into serological assays, to de...

Methods A group of 195 women who attended prenatal care outclinic and obstetric emergency department was tested concomitantly for by RT-PCR serological tests. Results The virus detected two (1.02%) cases 17 (8.71%) patients had antibodies immunochromatographic Conclusions Due high r...

in an attempt to convert mass vaccination practices to the extended programme on immunization, a sero-evaluation study was carried out in rural iran in 1976. a total of 22 246 rural children of 2-12 years of age were sampled. blood samples taken on filter paper were tested by indirect hemagglutination technique to determine the level of circulating antibodies against tetanus toxoid. tetanus was...

INTRODUCTION The aim of this study was to evaluate the serological cross-reactivity between Leishmania sp. and other canine pathogens. METHODS Positive serum samples for Ehrlichia canis, Babesia canis, Toxoplasma gondii, Neospora caninum and Trypanosoma cruzi were tested using three serological methods enzyme linked immunosorbent assay (ELISA), indirect immunofluorescent antibody test (IFAT) ...
