Precision biotic as an effective replacement of hydrolyzed yeast and butyrate in antibiotic free diets of broiler chickens raised under field conditions.

A total of 1,436,000 Ross 380 AP broiler chicks were included in the experiment, which was conducted in two cycles with 20 houses per cycle and 35,900 birds per house. The objective was to evaluate, under field conditions, the impact of a precision biotic (PB) on the growth performance and cecal microbiome of broiler chickens, in comparison to enzymatically hydrolyzed yeast (EHY) and butyrate (BT) in an antibiotic-free diet. Each cycle consisted of six (6) houses under PB supplementation, and 14 houses under the regular dietary program used by the integration.

Intraocular Metastatic Lung Adenocarcinoma Masquerading as an Intermediate Uveitis.

Purpose: To report on the clinical and cytopathological features of metastatic lung adenocarcinoma to the eye masquerading as an intermediate uveitis.

Methods: Retrospective chart review.

Results: A 63-year-old woman with a history of lung adenocarcinoma in remission presented with progressive vision loss and floaters in the right eye.

Avian influenza overview September-December 2024.

Between 21 September and 6 December 2024, 657 highly pathogenic avian influenza (HPAI) A(H5N1) and A(H5N5) virus detections were reported in domestic (341) and wild (316) birds across 27 countries in Europe. Many HPAI outbreaks in domestic birds were clustered in areas with high poultry density and characterised by secondary farm-to-farm spread. Waterfowl, particularly the mute swan, were primarily affected during this reporting period, with HPAI virus detections focused on south-eastern Europe.

Optimizing contact tracing for avian influenza in poultry flocks.

Contact tracing is commonly used to manage infectious diseases of both humans and animals. It aims to detect early and control potentially infected individuals or farms that had contact with infectious cases. Because it is very resource-intensive, contact tracing is usually performed on a pre-defined time window, based on previous knowledge of the duration of the incubation period.
