Antibiotic resistance of faecal enterococci in poultry, poultry farmers and poultry slaughterers [PDF]

Journal of Antimicrobial Chemotherapy, 2002
The prevalence of resistance in enterococci to antibiotics, commonly used for therapy in poultry or as antimicrobial growth promoters (AMGPs), was determined in faecal samples of two chicken populations: broilers in which antibiotic and AMGP use is common and laying-hens with a low antibiotic usage.

First report in Cuba of the presence of the louse Goniodes colchici (Denny, 1842) (Phthiraptera: Goniodidae) on Gallus gallus domesticus (Galliforme, Phasianidae).

Acta Scientiarum: Animal Sciences
Laying hens are affected by numerous species of lice. High infestations cause intense itching, irritation and destruction of feathers. In addition to interfering with the nutrition and rest of the birds, with the consequent impact on meat and egg ...

A New Threshold Switching Device With Tunable Negative Differential Resistance Based on ErMnO3 Polymorphs

Advanced Functional Materials, EarlyView.
Polymorph engineering in ErMnO3 enables low‐voltage, forming‐free threshold switching with tunable negative differential resistance. Conducting orthorhombic regions embedded in an insulating hexagonal matrix provide controlled Joule‐heating‐enhanced Poole–Frenkel transport. The hexagonal phase prevents excessive heating and breakdown.

Bio‐Inspired Multimodal Hardware Front‐End Enabled by 2D Floating‐Gate Memory for UAV Perception

Advanced Functional Materials, EarlyView.
A MoS2/h‐BN /graphene floating‐gate memory underpins a bio‐inspired multimodal front end that integrates visual, inertial, and airflow cues. A 4 × 4 FG memory array encodes temporal intensity differences, while IMU‐ and airflow‐driven threshold modulation suppresses self‐motion artifacts, enabling fast, low‐power, robust autonomous UAV tracking and ...
