We tested 41 bats for antibodies against Nipah and Hendra viruses to determine whether henipaviruses circulate in pteropid fruit bats (Pteropus giganteus) in northern India. Twenty bats were seropositive for Nipah virus, which suggests circulation in this species, thereby extending the known distribution of henipaviruses in Asia westward by >1,000 km.
To the Editor: The emergence of Nipah virus (NiV) in Malaysia in 1999 resulted in 265 known human infections (105 fatal), widespread infection in pigs (with >1 million culled to control the outbreak), and the collapse of the Malaysian pig export market (1). As with the closely related Hendra virus (HeV) that emerged in Australia in 1994 and caused fatal(More)
The indirect ELISA is a simple and useful method for detection of pathogen-specific antibodies in animal sera. However, non-specific or background binding is often a problem, especially when recombinant proteins from Escherichia coli are used. In this study, a comparative indirect ELISA in which the total reactivity and the background binding were(More)
Weaned pigs (6-week-old) and 7-day-old pre-weaned piglets were vaccinated with naked plasmid DNA expressing the gp55/E2 gene from classical swine fever virus (CSFV). Both groups of pigs were then given a booster dose of recombinant porcine adenovirus expressing the gp55 gene (rPAV-gp55). Following challenge with CSFV, 100% of weaned pigs and 75% pre-weaned(More)
To the Editor: Nipah virus (NiV) emerged in peninsular Malaysia in 1998 and 1999 as a respiratory and neurologic disease of domestic pigs and an acute febrile encephalitic disease in humans (1). Nipah virus infection is associated with a case-fatality ratio of 40% to 76% in humans (1,2). Cats (Felis catus) were infected with NiV at the site of the outbreak(More)
AIM To determine if pigs could support infection of a human Brucella isolate (Brucella 02/611) from New Zealand, and to study seroconversion to this isolate using a competitive ELISA. METHODS Ten weaner piglets were challenged with 4.8 x 10(8) cfu of organisms by the oral and ocular routes. Culture was attempted on blood samples taken prior to challenge,(More)
OBJECTIVE To measure the diagnostic performance of an Australian-developed ELISA for the detection of antibodies against the non-structural proteins (NSP) 3ABC of the foot and mouth disease (FMD) virus. DESIGN Test development and validation study. METHODS The diagnostic specificity was determined using 2535 sera from naïve animals and 1112 sera from(More)
Ferritin in serum from patients with increased serum ferritin levels has been studied both quantitatively and qualitatively. All techniques utilized in these studies are suitable to be used as routine screening tests for large numbers of patients. Electroimmuno assay (EIA) has been compared with the solid phase immunoradiometric (IRMA) assay as a technique(More)
