Is listeriosis becoming a problem in Europe and Slovenia?

This article describes the incidence and significance of infection with L. monocytogenes in humans and factors that commonly lead to infection. The majority of cases are sporadic, but in recent years, the genotyping of Listeria isolated from the environment, food and clinical samples linking unrelated cases importantly contributed to the general knowledge on epidemiology and ecology of listeriosis.

Escherichia coli producing extended spectrum beta-lactamases-genotypes of isolates from diseased animals and food of animal origin compared with genotypes of human clinical isolates

The aim of our study was to compare genotypes of E. coli strains isolated from human and animal infections and those from healthy food animals at slaughter. Our results corroborated recent findings showing that a high percentage of food animal isolates carried genes for enzymes of the CTX-M group. Additionally, this isolates encoded several virulence factor genes and belonged to the same phylogenetic group as human extraintestinal pathogenic E. coli. This supports the presumtion that food of animal origin can be the source of antimicrobial resistant and pathogenic strains.

Effect of treatment with Tris-EDTA/chlorhexidine topical solution on canine Pseudomonas aeruginosa otitis externa with or without concomitant treatment with oral fluoroquinolones

Traditional use of antibiotics alone or in combination with topical antiseptic solutions to treat Pseudomonas OE is often associated with the development of antibiotic resistance. Tris-EDTA/chlorhexidine solution is very active against several species of gram-positive and gram-negative bacteria in-vitro. Therefore, in-vivo effect of topical antiseptic solution containing Tris-EDTA/chlorhexidine 0.15% on clinical and microbiological parameters in 18 dogs diagnosed with Pseudomonas- associated OE, with (n=12) or without (n=6) the concomitant use of oral fluoroquinolones, was evaluated over an eight week period. Results indicated that the number of rod shaped bacteria and neutrophil granulocites decreased with time regardless of fluoroqinolone treatment. Similarly, all clinical signs were affected by Tris-EDTA/chlorhexidine treatment independently of fluoroqinolone treatment (P(0.05). Fluoroqinolone resistance was observed in P. aeruginosa in both, dogs that were, and those that were not treated with fluoroqinolones. Treatment with Tris-EDTA /chlorhexidine 0.15% combination solution seems to be beneficial for resolution of Pseudomonas- associated OE in dogs, which was independent of fluoroquinolone treatment.
