This study shows the effectiveness of vaccination with an E2 subunit vaccine against classical swine fever (CSF) in 2-week-old piglets. Half of the piglets were carrying maternally derived antibodies (MDAs) at the time of vaccination. Three and 6 months later, antibody levels were compared between the two treatments. Moreover, reduction of virus transmission was investigated at 3 and 6 months by doing transmission experiments. The vaccine was found to be capable of reducing virus transmission significantly at both time intervals. Maternal immunity reduced vaccination-induced antibody levels after 3 and 6 months and possibly led to a less effective protection against virus transmission after 6 months.

HIV infection implicates a spectrum of tissues in the human body starting with viral transmission in the anogenital tract and subsequently persisting in lymphoid tissues and brain. Though studies using isolated cells have contributed significantly towards our understanding of HIV infection, the tissue microenvironment is characterised by a complex interplay of a range of factors, all of which can influence the course of infection but are otherwise missed in ex vivo studies. To address this knowledge gap, it is necessary to investigate the dynamics of infection and the host immune response in situ using imaging-based approaches.

Mathematical and statistical methods are invaluable in epidemiological investigations, enhancing our understanding of disease transmission dynamics and informing effective control measures. In this study, we presented a method to estimate transmissibility using patient-level data, with application to the 2015 MERS outbreak at Pyeongtaek St. Mary's Hospital, the Republic of Korea.

T-cell response plays an important role in SARS-CoV-2 immunogenicity. For people living with HIV (PWH) and solid organ transplant (SOT) recipients there is limited evidence on the reliability of commercially available T-cell tests. We assessed 173 blood samples from 81 participants (62 samples from 35 PWH; 111 samples from 46 SOT recipients [lung and kidney]) with two commercial SARS-CoV-2 Interferon-γ (IFN-γ) release assays (IGRA; SARS-CoV-2 IGRA by Euroimmun, and IGRA SARS-CoV-2 by Roche).

Introduction: Nonhuman primates (NHPs) can transmit zoonotic diseases to humans because of their close genetic relationship, facilitating the cross-species transmission of certain pathogens. In Thailand, Macaca is the most common NHP genus and their inhabits area are in close proximity of human, particularly in urban and suburban areas, where frequent interactions with humans increase the risk of pathogen transmission. The risk is influenced by factors such as the type of pathogen, the mode of transmission (e.

Unlabelled: Members of the RNA virus order infect hosts ranging from marine invertebrates to terrestrial mammals. As such, understanding the determinants of host range in this group of viruses, as well as their patterns of emergence and disease potential, is of clear importance.
