AI Article Synopsis

  • - Toxoplasma gondii is a parasite affecting humans and wildlife, and a study in Taiwan looked at antibodies in 394 wild birds from 37 species, finding a seroprevalence of 23.35%.
  • - Birds of prey and those in aquatic environments had the highest infection rates, with adult birds showing greater seroprevalence compared to juveniles; clinical abnormalities were linked to infection.
  • - The findings indicate T. gondii is widely spread in Taiwan, raising concerns about its zoonotic potential and the need for further research on its impact on wild birds.

Article Abstract

Toxoplasma gondii is a zoonotic protozoon which is well known for infecting humans and wild animals. In the present study, antibodies to T. gondii were evaluated in 394 wild birds, belonging to 37 species, from 15 different administrative regions in Taiwan. Using modified agglutination test (MAT), the overall seroprevalence of infection was 23.35% (CI 95% = 19.17%-27.53%). Antibodies were detected in birds of prey (25.73%, CI 95% = 19.76%-31.70%), birds living in freshwater or marine systems (34.29%, CI 95% = 18.56%-50.01%) and ground-feeding birds (18.12%, CI 95% = 11.94%-24.31%). Adult birds showed higher seroprevalence than that in juvenile birds, and the presence of clinical abnormalities was associated with T. gondii seropositivity. The results showed that this pathogen has spread widely in Taiwan. This suggests the zoonotic potential of the disease, with transmission from urban to rural regions, and from terrestrial to aquatic systems. The pathogenicity of T. gondii infection in wild birds in Taiwan needs further investigation. This is the first study of the seroprevalence of T. gondii in wild birds in Taiwan.

H4Nx avian influenza viruses (AIVs) have been isolated from wild birds and poultry and can also cross the species barrier to infect mammals (pigs and muskrats). The widespread presence of these viruses in wild birds and poultry and their ability to be transmitted interspecies make them an undeniable hazard to the poultry farming industry. In the present study, we collected fecal and swab samples from wild birds and poultry in Guangdong Province from January 2019 to March 2024, and various subtypes of AIVs were isolated, including 19 strains of H4 subtype AIVs.

Influenza A virus (IAV) is a significant public health concern, causing seasonal outbreaks and occasional pandemics. These outbreaks result from changes in the virus's surface proteins which include hemagglutinin and neuraminidase. Influenza A virus has a vast reservoir, including wild birds, pigs, horses, domestic and marine animals.

Dealing with infections is a daily challenge for wild animals. Empirical data show an increase in reactive oxygen species (ROS) production during immune response. This could have consequences on telomere length, the end parts of linear chromosomes, commonly used as proxy for good health and ageing.

Bats are natural hosts for many emerging viruses for which spillover to humans is a major risk, but the diversity and ecology of bat viruses is poorly understood. Here we generated 8,176 RNA viral metagenomes by metatranscriptomic sequencing of organ and swab samples from 4,143 bats representing 40 species across 52 locations in China. The resulting database, the BtCN-Virome, expands bat RNA virus diversity by over 3.
