Occurrence of Pseudomonas Aeruginosa in Homemade Fresh Butter in Some Rural Areas in Kosovo

Enver Bajrami, Kapllan Sulaj


This study is carried out from 2014 to 2015 in some rural areas in Kosovo. From the analytical control samples of 87 fresh butter sampled collected from rural areas of Ferizaj and Gjilan in Kosovo are isolated 8% Pseudomonas spp strains. Further differentiation of isolated strains confirmed Pseudomonas aeruginosa in 4, 2% of collected samples. The identification of isolates was succeeded using planting techniques and peptone broth as well as selective media Pseudomonas CFC agar. All isolated strains produced protease and lipase by only 3 strains. Butter is stored in cold temperature at 4o C. In such
environment Pseudomonas aeruginosa cells are under inhibitory effects of low temperatures but they can survive. Inhibitory effects in milk cultures (cream and yogurt) have been observed in some cases of contamination of milk products with Pseudomonas aeruginosa.

Keywords: Pseudomonas aeruginosa, butter, fresh, Kosovo.
