A prospective cohort study on antimicrobial resistance on dairy cattle: prevalence among pathogens isolated from dairy farms in northern Italy and risk factors associated with antimicrobial resistance spreading.
The aim of the project is to check the presence and possible spread of antimicrobial resistance in herds concerning biosecurity levels and other herd characteristics and determine the prevalence of ESBL/AmpC-producing E. coli and to investigate their distribution on northern Italy farms.
There will be a herd selection and enrolled farms will be subjected to the Classyfarm Biosecurity checklist if not already present.
Based on the score obtained from the Classyfarm Biosecurity checklist, the farms will be divided into 3 groups:
- high biosecurity;
- intermediate biosecurity;
- low biosecurity.
Furthermore, information on general farm characteristics, management practice, and health status will be collected during an interview with the farmer.
A first sampling (T0) will be collected from each farm to assess the presence/absence of AMR on neonatal calves. This sampling will be performed on fecal samples from healthy and sick neonatal calves.
After that, a second sampling will be carried out on the farms enrolled in the study.
Faecal samples will be taken from both healthy calves and calves affected by NCD at the beginning of the year (T1) and the end of the year (T2) from each enrolled farm.
After an agreement with the farmer and the farm veterinarian, a faecal sample will be taken from calves showing diarrhoea.
