A nation wide study on the microbial aetiology of cases of acute clinical mastitis in Swedish dairy cows was conducted with the aim to investigate changes in the microbial panorama compared to a previous study performed 1994-1995. Another aim was to investigate some agent-specific environmental and individual risk factors. Milk samples were collected from(More)
To investigate occurrence of acquired antimicrobial resistance in udder pathogens MICs in Staphylococcus aureus (n=211), coagulase-negative staphylococci (CNS) (n=56), Streptococcus uberis (n=113), Streptococcus dysgalactiae (n=152), Streptococcus agalactiae (n=6), Escherichia coli (n=163), and Klebsiella spp. (n=42) were determined using microdilution.(More)
The banned use of antimicrobial growth promoters resulted in a considerably decreased use of antimicrobials in food animal production in Sweden (65%), Denmark (47%), Norway (40%) and Finland (27%). The current prevalence of antimicrobial resistance in animal bacterial populations is also considerably lower than in some other countries in the EU. In the(More)
An in vivo model for studies of pharmacokinetic/pharmacodynamic (PK/PD) interactions of antimicrobials was developed. Tissue cages with a constant surface area but with different volumes were implanted in calves and infected with Mannheimia haemolytica. Penicillin was injected directly into the cages. With this procedure, different concentration-time(More)
AIMS In this study, the molecular diversity among clones of vancomycin resistant Enterococcus faecium with vanA gene (VRE) is investigated. The aims were to better understand why one clone is predominant in Swedish broiler production and to better assess the potential for zoonotic gene transfer from the different clones. METHODS AND RESULTS Twenty-six(More)
OBJECTIVE To evaluate an experimental model of the pharmacokinetic/pharmacodynamic (PK/PD) relationship of danofloxacin against Mannheimia haemolytica infection, using subcutaneously implanted tissue cages in calves. METHODS Tissue cages implanted subcutaneously in calves were infected with M. haemolytica and different concentration-time profiles of(More)
BACKGROUND In Sweden, knowledge about the role of enteropathogenic Escherichia coli in neonatal calf diarrhea and the occurrence of antimicrobial resistance in E. coli from young calves is largely unknown. This has therapeutic concern and such knowledge is also required for prudent use of antimicrobials. METHODS In a case control study Esherichia coli(More)
BACKGROUND Vancomycin resistant enterococci are a frequent cause of nosocomial infections and their presence among farm animals is unwanted. Using media supplemented with vancomycin an increase in the proportion of samples from Swedish broilers positive for vancomycin resistant enterococci has been detected. The situation at farm level is largely unknown.(More)
