Highly pathogenic avian influenza (HPAI) H5 virus exposure in domestic cats and rural stray cats, the Netherlands, October 2020 to June 2023.
Euro Surveill
October 2024
Article Synopsis
- * Out of 701 stray cats, 11.8% tested positive for HPAI H5, while only 0.46% of 871 domestic cats were positive, showing stray cats are exposed more often, likely from hunting wild birds.
- * Additionally, stray cats in nature reserves and older cats had higher odds of being HPAI H5 positive, while domestic cats showed more exposure to H1 influenza viruses.
Prevalence of elephant endotheliotropic herpesvirus (EEHV) infections in Asian elephants in Japan was assessed by determination of EEHV gB specific antibody levels. Among 28 healthy Asian (sub) adult elephants from 11 zoos, 27 animals exhibited intermediate to high antibody levels. Like elsewhere worldwide, this suggested exposure of Asian elephants in Japan to at least one EEHV (sub) species.

- A study examined different partition layouts in open-plan offices to enhance speech privacy while maintaining effective communication among workers.
- Four layouts—face-to-face, parallel, crossed-rod, and orthogonal—were tested using computer modeling at heights of 1.2, 1.5, and 1.8 meters.
- Results indicated that parallel and crossed-rod layouts provided the best speech privacy at lower heights, with face-to-face setups being the least effective, emphasizing the need for strategic office design and worker spacing to improve privacy.
Elephant endotheliotropic herpesvirus (EEHV) causes lethal hemorrhagic disease (HD) in Asian and African elephants. Although rapid detection of viremia and supportive treatments may improve survival rates, an effective vaccine would mitigate the devastating effects of this virus. In elephants, chronic infection with EEHV leads to adaptive immunity against glycoproteins gB and gH/gL, the core entry machinery for most herpesviruses.

Sialic acid (Sia)-binding paramyxoviruses contain a hemagglutinin-neuraminidase (HN) protein that possesses both Sia-binding and -cleavage activities. The multivalent, dynamic receptor interactions of paramyxovirus particles provide virion motility and are a key determinant of host tropism.
