Recombinant Dense Granule Protein (NcGRA4) Is a Novel Serological Marker for Infection in Goats.

is widely recognised as one of the most significant causes of abortion in cattle, with infections also occurring in sheep and goats. To prevent and control animal neosporosis, it is crucial to develop sensitive and specific methods for detecting infection. Recently, several recombinant proteins have been utilised in serological assays for the diagnosis of neosporosis.

SARS-CoV-2 Seroprevalence in Unvaccinated Adults in Thailand in November 2021.

Between the first case of COVID-19 in January 2020 and the end of 2021, Thailand experienced four waves of the epidemic. The third and fourth waves were caused by the alpha and delta strains from April 2021 to November 2021. Serosurveillance studies provide snapshots of the true scale of the outbreak, including the asymptomatic infections that could not be fully captured by a hospital-based case detection system.

Development and evaluation of recombinant GRA8 protein for the serodiagnosis of Toxoplasma gondii infection in goats.

Background: The development of sensitive and specific methods for detecting Toxoplasma gondii infection is critical for preventing and controlling toxoplasmosis in humans and other animals. Recently, various recombinant proteins have been used in serological tests for diagnosing toxoplasmosis. The production of these antigens is associated with live tachyzoites obtained from cell cultures or laboratory animals for genomic extraction to amplify target genes.
