Evaluation of 16 commercial antibody ELISAs for the detection of bovine viral diarrhea virus-specific antibodies in serum and milk using well-characterized sample panels.

s (min. 94%, max. 100%). Both DS e and AS e were lower when testing milk samples compared to serum samples. These results confirm that serologic monitoring of BVDV-free herds should be performed using serum ...

Comparative Tick-Borne Encephalitis (Virus) Surveillance in Belgium 2009-2015: Experiences with Diagnostic Tests, Sentinel Species and Surveillance Designs

describes 5 Belgian veterinary serological studies with enzyme-linked immunosorbent assays and seroneutralisation tests (ELISA / SNT), in which several surveillance schemes were used (active/passive, ...

A more sensitive, efficient and ISO 17025 validated Magnetic Capture real time PCR method for the detection of archetypal Toxoplasma gondii strains in meat.

the diagnosis of toxoplasmosis. Whereas serological tests are useful to prove contact with the parasite has occurred, the actual presence of the parasite in the tissues of a seropositive animal is not ...

Belgian Wildlife as Potential Zoonotic Reservoir of Hepatitis E Virus.

E virus (HEV) and can have a zoonotic origin, particularly in high-income countries. In this study, 383 sera from wild boars were selected for serology; for virological analyses, 69 sera and 61 livers from ...

Prenatal diagnosis and prevention of toxoplasmosis in pregnant women in Northern Vietnam: study protocol.

followed-up by the gynaecologists according to a predefined protocol. Every participant will be informed on her serological status, risk factors and prevention measures and is offered appropriate medical ...

Outbreak investigations and molecular characterization of foot-and-mouth disease viruses circulating in south-west Niger.

determined by the two-dimensional virus neutralization test (2dmVNT), revealing a close antigenic match between the field isolate from Niger and three FMDV serotype O vaccine strains. Serological analyses ...

Detection and characterization of Brucella spp. in bovine milk in small-scale urban and peri-urban farming in Tajikistan.

addition, sequence analysis of the rpoB gene suggests that one cow was infected with B. abortus and another cow was most likely infected with B. melitensis. The discrepancies between the serology and ...

Pre-registration efficacy study of a novel marker vaccine against classical swine fever on maternally derived antibody positive (MDA+) target animals.

treatment groups using generalized randomized block design (GRBD) blocking on serological status and pen location. Of the 40 piglets with MDA s, 30 piglets were vaccinated either orally (n = 15) or ...

Evaluation of three competitive ELISAs and a fluorescence polarisation assay for the diagnosis of bovine brucellosis.

low specificity, especially when used in a herd. C- ELISA3 could not be recommended as confirmatory test on individual animals to determine whether false positive serological test results had occurred. ...

Seroprevalence of brucellosis in patients with prolonged fever in Bangladesh.

METHODOLOGY: Blood samples were collected from 300 pyretic patients from October 2007 to May 2008 and subjected to three serological tests: Rose-Bengal plate test (RBT), standard tube agglutination test (STAT), ...
