The aim of this study was to monitor the antimicrobial activity of honey. The effects of 44 samples of honey (29 blossom honeys, 15 honeydew honeys) were tested using an agar dilution method on 65 bacterial strains (genera Staphylococcus, Streptococcus, Listeria, Klebsiella, Escherichia and Paenibacillus). All the samples of honey inhibited the growth of all … [Read more…]
Enterococcus spp. is the most controversial group of lactic acid bacteria that have been ascribed a beneficial or detrimental role in food and feed. The aim of our study was to monitor the occurrence of Enterococcus spp. in collected samples of meat and meat products. Enterococci originated from 34 meat and meat product samples collected … [Read more…]
A total of 460 raw goat colostrum samples (424 native, 36 lyophilised) from Czech ecological farms were analysed during the years 2012 – 2015. The aim of this study was to determine the microbial safety of goat colostrum in the Czech Republic (the presence of Listeria monocytogenes, Salmonella spp., Shiga toxin-producing Escherichia coli (STEC), methicillin-resistant … [Read more…]
Staphylococcus aureus produces a variety of toxins, some of which may cause staphylococcal intoxication. The aim of this study was to isolate S. aureus bacteria from samples of raw meat from the retail market in the Czech Republic and to determine the prevalence of genes encoding the production of staphylococcal enterotoxins in them. On the … [Read more…]
The aim of this study was to detect psychrotrophic lactobacilli, to monitor the occurrence of Lactobacillus curvatus and Lactobacillus sakei in raw pork meat and pork ham, and to compare the results of the identification of bacteria by MALDI-TOF mass spectrometry and genus- and species-specific polymerase chain reaction (PCR). The samples (n = 23) came … [Read more…]
This study focused on the comparison and characterisation of Escherichia coli ( E. coli) isolates obtained from the meat of slaughtered animals (n = 34) and from raw cow’s milk (n = 33). Resistance to important antimicrobial substances and the presence of virulence factors were determined. Resistance to antimicrobials was tested using a disk diffusion … [Read more…]
The aim of this study was to monitor the frequency of lactobacilli in ready-to-eat meat products and to determine the species and the antimicrobial susceptibility. Identification of suspect isolates was investigated in this work by polymerase chain reaction. A total of 148 samples of meat products were examined, and lactobacilli were detected in 107 samples … [Read more…]
The aim of this study was to determine the number of coagulase-positive staphylococci (Staphylococcus aureus) using the automated TEMPO STA system on samples of the Vysočina- type of heat-treated dry salami stored at 2 different temperatures and to detect the presence of SEA with the MiniVIDAS device. These samples were inoculated with a known strain … [Read more…]
Swabs taken from slaughtered pigs, raw porcine meat, liver, and ready-to-eat meat products from the retail market were analysed for the presence of Salmonella spp. Of 163 swabs from slaughtered pigs 8 were positive, of 122 samples of raw pork and minced meat none were positive, and of 72 liver samples 5 were positive for … [Read more…]
