Multiresistance of Staphylococcus xylosus and Staphylococcus equorum from Slovak Bryndza cheese.

Staphylococcus xylosus, Staphylococcus equorum, and Staphylococcus epidermidis strains were isolated from Bryndza cheese and identified using PCR method. The antimicrobial susceptibility of these strains was assessed using disc diffusion method and broth microdilution method. The highest percentage of resistance was detected for ampicillin and oxacillin, and in contrary, isolates were susceptible or intermediate resistant to ciprofloxacin and chloramphenicol.

Probiotic potential and safety properties of Lactobacillus plantarum from Slovak Bryndza cheese.

One hundred and twenty-five acid-resistant presumptive lactobacilli were isolated from Slovak Bryndza cheese and screened for their antimicrobial activity against eight bacterial pathogens using spot agar assay. Out of twenty-six Lactobacillus strains with strong inhibition activity, twenty were identified as Lactobacillus plantarum and six as Lactobacillus fermentum. The most active eleven L.

Transcriptome analysis of the Euglena gracilis plastid chromosome.

The characterisation of transcript levels of chloroplast genes and their changes under different conditions is an initial step towards understanding chloroplast gene expression and the functional integration of the plastid chromosome into the entire integrated compartmentalised genome of the plant cell. Using RNA from cells of 12 different developmental stages and stress treatments, we have studied the transcript patterns of all 96 genes of the circular plastid chromosome of Euglena gracilis, Pringsheim strain Z, by a macroarray-based approach and Northern analysis of selected genes representing approximately half a dozen operons. The unicellular alga possesses complex, triple-envelope chloroplasts that were acquired by secondary endosymbiosis.

Antimicrobial susceptibility of Enterococcus species isolated from Slovak Bryndza cheese.

Three hundred and ten enterococcal isolates (178 Enterococcus faecium, 68 E. durans, 49 E. faecalis, 8 E.

Molecular identification and diversity of enterococci isolated from Slovak Bryndza cheese.

Three hundred and eight presumed enterococcal isolates were recovered from Bryndza, a soft sheep milk cheese. The cheese samples were obtained from five different commercial distributors in Slovakia and were taken at three different seasonal intervals. All isolates were identified to the species level using genotypic tools.
