To guide control policies, it is important that the determinants of influenza transmission are fully characterized. Such assessment is complex because the risk of influenza infection is multifaceted and depends both on immunity acquired naturally or via vaccination and on the individual level of exposure to influenza in the community or in the household. Here, we analyse a large household cohor...

Highly Pathogenic Avian Influenza (HPAI) H5N1 is a major problem in poultry industry many countries. It became endemic disease Indonesia since 2003. Recently, research revealed that current circulate HPAI has switched from clades 2.1 to 2.3.2.1. To eradicate this disease, methods such as stamping out and quarantine seem not suitable applied one of main sector agricultural commodity some areas C...

Serological monitoring is a feature of surveillance programmes for the detection of the circulation of notifiable low pathogenic avian influenza (LPAI) viruses in commercial poultry holdings. Commercial multispecies nucleoprotein (NP) enzyme-linked immunosorbent assays (ELISAs) have been replacing the haemagglutination inhibition (HI) test as pre-screening tools. Few comparative studies have be...

The study was aimed at determining the prevalence of pandemic influenza (H1N1) 2009 among patients with respiratory tract diseases during July-December 2009 using real-time reverse transcription polymerase chain reaction. Haemagglutination inhibition (HI) assay was performed to detect antibody titres against pandemic influenza in 255 medical personnel, 307 members of the general population duri...

In Vietnam, serological post H5N1 vaccination surveillance using the HI test is applied to assess the efficiency of the vaccination in addition to virological monitoring. In this paper we report on the evaluations of the performances of the haemagglutination inhibition (HI) test and of a H5-ELISA, using chicken and duck field samples. The evaluations were conducted by comparison with a pseudoty...

Between January 1990 and September 1992, thirty patients ranging in age from 7 months to 43 years with a diagnosis of dengue fever (DF) or dengue haemorrhagic fever (DHF) were admitted to the Intensive Care Unit (ICU) of the University Hospital, Kuala Lumpur. 21 of these patients were serologically confirmed to have dengue infection by either IgM-capture ELISA andfor haemagglutination inhibitio...

Newcastle Disease (ND) has been recognized for a long time as one of the major production and health constraints to rural poultry. There have been increasing reports by private veterinarians of ND outbreaks in commercial farms in the Federal Capital Territory (FCT), Nigeria but the epidemiological status of the disease in local chickens is unknown and outbreaks are usually not reported. A serol...

This study describes an epizootic of respiratory tract disease caused by influenza virus infection in a large population of equines in Luxor and Aswan, Upper Egypt, during the winter of 2000. The epizootic started in January and the infection rate reached its peak in February before gradually decreasing until the end of April, 2000. Horses, donkeys and mules of all ages and both sexes were affe...

Untreated earlobe capillary blood samples from 5958 girls were screened for rubella antibodies by placing them directly onto haemolysis-in-gel (HIG) test plates. The method is in our experience quick, reliable and also acceptable to young girls. The method is convenient for testing for natural immunity before vaccination and in most but not all cases satisfactory as a test for seroconversion af...

A dot enzyme immunoassay (DEIA) for the detection of antibodies to dengue virus was tested for use as a tool in the presumptive diagnosis of dengue fever and dengue haemorrhagic fever. Paired sera from the following groups of patients were tested using the DEIA and the haemagglutination inhibition (HI) test: those with primary dengue fever; those experiencing a second dengue infection; and febr...
