Higher complement C4 gene copy number constitutes a shared genetic risk factor for giant cell arteritis and IgA vasculitis

open access: yesArthritis &Rheumatology, Accepted Article.
Objective Low copy number (CN) of complement C4 isoforms and high CN of retroviral HERV‐K elements are known risk factors for many immune‐mediated inflammatory diseases (IMIDs), often showing sex‐biased effects. Here, we assessed whether CN variation within the C4 gene contributes to giant cell arteritis (GCA) and IgA vasculitis (IgAV), two complex ...

Contributions of birds to the feeding of ticks at host community level: Effects of tick burden, host density and yearly fluctuations

open access: yesTicks and Tick-Borne Diseases
The eco-epidemiology of tick-borne diseases hinges on the abundance and distribution of hosts that sustain tick populations and the pathogens they carry.

Injuries in deep time: interpreting competitive behaviours in extinct reptiles via palaeopathology

open access: yesBiological Reviews, EarlyView.
ABSTRACT For over a century, palaeopathology has been used as a tool for understanding evolution, disease in past communities and populations, and to interpret behaviour of extinct taxa. Physical traumas in particular have frequently been the justification for interpretations about aggressive and even competitive behaviours in extinct taxa.

Case Report on the Management of Bird Feathers and Droplet Infection in Lungs

open access: yesJournal of Pharmacy and Bioallied Sciences
Birds can carry most of the diseases. The few diseases are people’s bird feathers and droplets infection in the lungs. Because it occurs due to very close and regular contact with the birds, it affects the human immune system.

Long‐term trends in parasite diversity and infection levels: approaches and patterns

open access: yesBiological Reviews, EarlyView.
ABSTRACT Parasites exist in every ecosystem, affecting nearly all organisms and playing a complex role in human societies. On the one hand, they contribute substantially to biodiversity and support ecosystem stability by performing essential ecological functions.

The spread of non‐native species

open access: yesBiological Reviews, EarlyView.
ABSTRACT The global redistribution of species through human agency is one of the defining ecological signatures of the Anthropocene, with biological invasions reshaping biodiversity patterns, ecosystem processes and services, and species interactions globally.

Parrot Trade and the Potential Risk of Psittacosis as a Zoonotic Disease in Indonesian Bird Markets

open access: yesBirds
Wildlife trade, both legal and illegal, is increasingly recognized as a key factor in the rise of emerging viral infectious diseases, and this is especially apparent in Asia, where large numbers of wildlife are openly offered for sale in bird markets. We

The impacts of biological invasions

open access: yesBiological Reviews, EarlyView.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological
