Influence of different milking methods on milk quality based on somatic cell count and basic composition.

Introduction And Objective: Correlations between the number of milk somatic cells (SCC), the number of microorganisms, and the content of basic components of milk were studied on five farms (F1-F5) with cows of the same breed, but with different milking systems.

Material And Methods: From each farm, 50 Holstein Friesien milk samples were collected once a month (250 samples/month; n=3,000) during March 2022 - February 2023. Samples from farms F1 and F5 were tested for fat, protein, lactose, no fat dry matter content (FTIR spectroscopy), for the SCC (Fossomatic 7), and for the differential cells (Vetscan DC-Q).

Detection of Gluten in Gluten-Free Foods of Plant Origin.

The work deals with the issue of standardization and more accurate methodology for the isolation of gluten DNA in gluten-free products of plant origin, which is more demanding due to the more complex structure of plant cells. Three isolation methods were compared, of which the combination of glass and zirconium beads, Proteinase K and a commercially produced isolation kit was confirmed to be the most effective procedure. The given isolation procedure was more effective in one-component gluten-free foods, where the concentration of the obtained DNA ranged from 80.

Antimicrobial Resistance of sp. Isolated from Sheep and Goat Cheeses.

This study aimed to calculate the proportion of antibiotic resistance profiles of , and isolated from traditional sheep and goat cheeses obtained from a selected border area of Slovakia with Hungary (region Slanské vrchy). A total of 110 sp. were isolated from cheese samples, of which 52 strains ( (12), (28), (12)) were represented.

Detection of Antimicrobial Resistance of Bacteria Isolated from Sheep's Milk and Cheese.

Antimicrobial and multidrug resistance is detected in nonaureus staphylococci, including , which commonly causes intramammary infections. Recent clinical studies point to the presence of methicillin-resistant Therefore, this study aims to determine the prevalence of this species in samples of sheep's milk and cheeses made from them. Isolates were identified by polymerase chain reaction and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF).
