(PDF) Molecular epidemiology and antimicrobial resistance. 20/6/2019 · Furthermore, antimicrobial resistance of Salmonella in pigs is a global concern, with resistance to at least one antimicrobial observed in 92% of Salmonella isolates in the UK 9. Consequently, a reduction in the prevalence of Salmonella in pigs arriving at slaughter is a high priority for many countries, and subject to national control, resistance (AMR) in certain bacteria in UK pigs, several of which are of public health significance. This work extended a prevalence study for Salmonella in pigs, to take the opportunity to estimate the prevalence of Toxoplasma, HEV, Yersinia, PRRSv and ESBL E. coli.

Phylogenetic characterization of Salmonella enterica from. 13/1/2017 · Salmonella has significant public health implications causing food borne and zoonotic diseases in humans. Treatment of infections due to Salmonella is becoming difficult due to emergence of drug resistant strains. There is therefore need to characterize the circulating non-typhoidal Salmonella (NTS) serovars in domestic animals and animal, colonization by Salmonella. Studies of genetic resistance in domestic animals have focused on two broad aims. The first is to reduce the levels of disease and economic losses through high mortality rates of systemic salmonellosis caused by Salmonella serovars such as Salmonella choleraesuis in pigs (Van Diemen et al., 2002), or Salmonella gallina-.

Genetic resistance to Salmonella infection in experimental animal models is well described. However, genetic resistance in domestic animals, which has potentially great value in terms of controlling Salmonella in the food chain, has been relatively poorly described. Moreover, varying occurrence/prevalence rates of presumptive ESBL/AmpC resistance in Salmonella monitored in meat, fattening pigs and calves and in Salmonella monitored in humans were observed between countries (EFSA, ECDC, 2019). 4.2.
