Southeastern Cooperative Wildlife Disease Study, University of Georgia, Athens, GA, USA.
Aspergillosis is the most commonly and widely reported fungal infection in birds. Disease development is often secondary to stressors that cause immunocompromise, and it is typically regarded as a disease of captivity. We retrospectively evaluated data from 133 birds diagnosed with aspergillosis at the Southeastern Cooperative Wildlife Disease Study from 2001-2023 to assess diversity and relative frequency across avian taxa, gross and histologic lesion patterns, and comorbidities.

H7N9 avian influenza virus (AIV) first emerged in February 2013 in China, and early isolates were all low pathogenic (LP). After circulation for a few years in live poultry markets of China, LP H7N9 AIVs evolved into a highly pathogenic (HP) form in late 2016. Deduced amino acid sequence analysis of hemagglutinin (HA) gene revealed that all HP H7N9 AIVs have obtained four-amino-acid insertion at position 339-342 (H7 numbering), making the cleavage site from a monobasic motif (LP AIVs) to a polybasic form (HP AIVs).

The seasonal trends and profiles of respiratory viruses vary by region and season. Due to limited information and the population's vulnerability, we conducted the hospital-based surveillance of respiratory viruses in Eastern Uttar Pradesh.

Programme for Emerging Infections, Infectious Disease Division, International Centre for Diarrhoeal Disease Research, Bangladesh (icddr,b), Mohakhali, Dhaka 1212, Bangladesh.
Background: Influenza remains a significant public health challenge in low- and middle-income countries (LMICs) like Bangladesh, where vaccine uptake remains low despite the substantial disease burden. Physicians play a vital role in promoting vaccination, yet their intentions and influencing factors are not well understood.
Methods: We conducted a cross-sectional study from June to October 2022 across four tertiary-level hospitals in Bangladesh using a questionnaire grounded in the Theory of Planned Behavior (TPB).
Retrospective cross-sectional study on bronchiectasis in adult Aboriginal Australians: disease characteristics and comparison with ethnically diverse global bronchiectasis registry cohorts.
BMJ Open Respir Res

Darwin Respiratory and Sleep Health, Darwin Private Hospital, Darwin, Northern Territory, Australia.
Background: Globally, adult Indigenous people, including Aboriginal Australians, have a high burden of chronic respiratory disorders, and bronchiectasis is no exception. However, literature detailing bronchiectasis disease characteristics among adult Indigenous people is sparse. This study assessed the clinical profile of bronchiectasis among adult Aboriginal Australians and compared against previously published international bronchiectasis registry reports.
