As free-living crows are a potential source of Campylobacter infections in broilers and cattle, we characterized Campylobacter spp. isolated from crows using multilocus sequence typing and antimicrobial susceptibility testing. We obtained 82 samples from 27 birds captured at seven different times using a trap set in Tochigi prefecture, Japan. Campylobacter jejuni was isolated from 55 (67.1%) of the 82 samples and classified into 29 sequence types, of which 21 were novel. Tetracycline and streptomycin resistance rates were 18.2% and 3.6%, respectively. These results show that most types of C. jejuni infecting crows differ from those isolated from humans, broilers, and cattle. Thus, the importance of free-living crows as reservoirs of Campylobacter infections in broilers and cattle may be limited.

Background: Biosecurity is a key strategy for reducing poultry diseases and increasing farm productivity and profitability. In Cameroon where infectious diseases represent one of the main constraint in poultry sector, data on on-farm biosecurity implementation is scarce. This study assessed livestock farmers' advisors' knowledge of biosecurity and evaluated biosecurity compliance on Cameroonian broiler farms.

When pigs and beef cattle are processed in a slaughterhouse, the inedible parts are often used to produce meat and bone meal, which is a valuable supplement for pigs and chickens. However, the production of meat and bone meal requires heating, which can reduce the amino acid (AA) digestibility of this byproduct in pigs and chickens. Therefore, the objective of the current study was to determine the effects of species, heat damage, and interaction between these factors on standardized ileal digestibility (SID) of AA in meat and bone meal.

(1) Background: Understanding the distribution of serovars in food, animals, and their environments is crucial for identifying infection sources and monitoring pathogen prevalence in the food chain. This study analysed serovars in Poland from 2016 to 2020, focusing on their epidemiological significance. (2) Methods: Isolation of was carried out following PN-EN ISO 6579 standards, and serotyping was performed using the White-Kauffmann-Le Minor scheme.

In the last decades, significant progress in welfare assessment of commercially farmed species has been achieved. Since then, various initiatives applied and improved existing protocols, or developed new ones for species like farmed rabbits or fish. This has resulted in a wide range of protocols, indicators and measures potentially lacking standardization and harmonization.

Understanding the sources and fate of antibiotics from livestock, humans, and aquaculture, as well as their transport via rivers to reservoirs, is crucial to design effective management strategies to mitigate associated risks. This study investigates the sources, fate, and transport of antibiotic residues in the river-reservoir system to inform strategies for mitigating their ecological impacts on water-related ecosystem. The MARINA-antibiotics (China-1.
