Article Synopsis
- Respiratory diseases in pigs lead to production losses and higher use of antibiotics on farms.
- An analysis of lung and pleural lesion scores from pig carcasses at slaughterhouses in Italy was conducted to assess the effectiveness of antimicrobial use (AMU) on 113 farms.
- Significant correlations were found between lung scores and the use of critical antimicrobials, suggesting that monitoring these lesions can help improve antibiotic management and reduce unnecessary usage.
Article Synopsis
- Optimizing antimicrobial usage (AMU) in livestock is essential to combat antimicrobial resistance, and a study analyzed AMU in over 1,000 cattle herds in Aosta Valley, Italy, from 2008 to 2018.
- Dairy cows comprised more than 95% of the total AMU, with average annual herd-level AMU being low, but significant use of third and fourth generation cephalosporins and intramammary antimicrobials was noted.
- The study found decreasing trends in total AMU over time and a positive association with herd size, suggesting the need for ongoing monitoring and prudent AMU practices even in small farms to ensure any potential issues are addressed.
Gastric lesions in pigs cause welfare and economic losses. Their prevalence in heavy pigs reared for premium products (e.g.

- Respiratory diseases in pigs are a significant issue in production, and assessing lung lesions at slaughter can aid in disease surveillance and epidemiology.
- Variations in assessment methods, observers, and abattoir practices create inconsistencies, making it difficult to compare research findings.
- This study compared two scoring systems for lung lesions in pigs and found that while both methods agreed on severe lesions, they differed in identifying healthy lungs, suggesting the Blaha method is better for surveillance, whereas Madec offers more detailed information for farm assessments.
Article Synopsis
- The rise of colistin resistance is concerning since colistin is a last-resort drug for serious gram-negative bacterial infections in humans.
- A mobile colistin resistance gene was isolated from a piglet in Italy, marking the first detection of this gene from animal sources in that region.
- Whole genome sequencing showed the strain was resistant to multiple antibiotics but surprisingly susceptible to colistin, indicating that the gene could persist in an environment with no colistin use due to the presence of other neighboring resistance genes.
Information regarding the relationship between animal welfare (AW) and antimicrobial use (AMU) in dairy cows is limited. The current study aimed to investigate this relationship on Italian farms and to identify potential targets of AMU reduction. The study was performed at 79 Italian dairy farms housing over 15,000 cows during 2019.

AMI and PMI are equally essential to guarantee food safety and to monitor swine health and welfare. However, little is known about the ability of AMI to predict conditions that are possibly found during PMI.
View Article and Find Full Text PDFThe complex health problem of antimicrobial resistance (AMR) involves many host species, numerous bacteria and several routes of transmission. Extended-spectrum β-lactamase and AmpC (ESBL/AmpC)-producing are among the most important strains. Moreover, wildlife hosts are of interest as they are likely antibiotics free and are assumed as environmental indicators of AMR contamination.
