Description
Przedmiotem wynalazku jest preparat sluzacy do wykrywania i oznaczania antybiotyków, który moze byc stosowany w przemysle spozywczym, medycynie, lecznictwie weterynaryjnym itp. Wprowadzenie antybiotyków do leczenia chorób zakaznych ludzi i zwierzat wplynelo zasadniczo na poprawe zdrowotnosci czlowieka i zwierzat hodowlanych. Jednoczesnie powszechne naduzywanie antybiotyków sprawilo, ze w coraz wiekszym stopniu przedostaja sie one do surowców rolnych szczególnie do miesa i mleka, powodujac szkody w produkcji, szczególnie przy wytwarzaniu fermentowanych artykulów spozywczych, jak: sery, maslo, twarogi, niektóre wedliny stwarzajac niebezpieczenstwo dla konsumentów. Stad tez wynika potrzeba badania obecnosci antybioty¬ ków w medycynie weterynaryjnej i przemysle spozywczym.The subject of the invention is a preparation for the detection and determination of antibiotics, which may be used in the food industry, medicine, veterinary medicine, etc. The introduction of antibiotics for the treatment of infectious diseases in humans and animals, it significantly improved human health and farm animals. At the same time, the widespread abuse of antibiotics has made it increasingly more the extent to which they get into agricultural raw materials, especially into meat and milk, causing damage to production, especially in the production of fermented food products, such as: cheese, butter, cottage cheese, some meats posing a danger to consumers. Therefore, there is a need to test the presence of antibiotics in the veterinary medicine and food industry.
Biologiczne metody oznaczania antybiotyków, polegaja na okreslaniu wzrostu mikroorganizmu wrazliwego na antybiotyki w obecnosci badanego materialu. Najczesciej stosowana metoda mikrobiologiczna jest metoda dyfuzji na stalym podlozu, w której jako podstawe ukladu testowego stosuje sie podloze odzywcze zawierajace odpowiednie drobnoustroje testowe. Znane i stosowane jest tylko podloze odzywcze i kazdorazowo osobno przygotowuje sie kulture bakterii testowej i dodaje do uprzednio przygotowanego podloza odzywczego w temperaturze nieszkodliwej dla drobnoustrojów testowych.The biological methods of antibiotic determination are based on determining the growth of a sensitive microorganism to antibiotics in the presence of the test material. The most commonly used microbiological method is the method diffusion onto a solid support where a nutrient medium containing suitable test organisms. Only the nutrient medium is known and used, and each time separately a test bacterium culture is prepared and added to a previously prepared nutrient medium at a temperature harmless to test microorganisms.
Natomiast nie znany jest preparat w formie suszonej sluzacy do bezposredniego oznaczania antybiotyków, który zawiera w swoim skladzie równoczesnie podloze odzywcze i utrwalona kulture testowa. Przy stosowaniu Bacillus stearothermophilusjako bakterii testowej stosowane jest podloze odzywcze o skladzie: ekstrakt miesny 0,15% ekstrakt drozdzowy 0,3% pepton z kazeiny 0,6% pepton z miesa 0,1% glukoza 0,1% pH = 7,02 100028 Niedogodnoscia znanych i stosowanych metod dyfuzyjnych oznaczania antybiotyków jest to, ze zakladaja one prowadzenie w kazdym laboratorium hodowli mikroorganizmu testowego: przygotowania jego zawiesiny, jej standaryzacja, odrebne przygotowanie podloza testowego i dodatek do niego mikroorganizmu. W ten sposób przygotowana kulture testowa dodaje sie do uprzednio uplynnionego i sterylizowanego podloza przed zastygnie¬ ciem agaru, co wplywa na wydluzenie czasu analizy i zwiekszenie jej pracochlonnosci wynikajacej z koniecznos¬ ci osobnego kazdorazowego przygotowania kultur testowych.However, there is no known dried preparation for the direct determination of antibiotics, which contains both a nutrient substrate and a well-established test culture. When applying Bacillus stearothermophilus as a test bacterium is a nutrient medium composed of: meat extract 0.15% yeast extract 0.3% casein peptone 0.6% meat peptone 0.1% glucose 0.1% pH = 7.02 100028 The disadvantage of the known and used diffusion methods for the determination of antibiotics is that they assume they carry out in each laboratory the cultivation of the test microorganism: preparation of its suspension, her standardization, separate preparation of the test medium and addition of the microorganism to it. In this way the prepared test culture is added to a previously liquefied and sterilized medium before it solidifies agar, which extends the time of analysis and increases its laboriousness resulting from the necessity to separate preparation of test cultures each time.
Celem wynalazku jest uzyskanie trwalego standaryzowanego preparatu w stanie suchym o odpowiednich wlasciwosciach dyfuzyjnych, ze wskaznikiem ulatwiajacym, obiektywizujacym i przyspieszajacym odczyt, który eliminuje czynnosci wstepne wystepujace przy wykrywaniu antybiotyków metoda dyfuzyjna, zwiazanym z przygotowaniem podloza, roztworów wskaznikowych, otrzymania zawiesiny bakterii testowych itp.The aim of the invention is to obtain a stable, standardized formulation in a dry state with suitable diffusion properties, with an indicator that facilitates, objectifies and accelerates the reading, which eliminates the preliminary steps involved in the detection of antibiotics by the diffusion method, related to with the preparation of the substrate, indicator solutions, obtaining a suspension of test bacteria, etc.
