… screening-tester. I dessa screening-tester ingår PCR-analys av mecA, nuc och/eller Sa442. MecA är lokaliserad på Staphylococcal Cromosomal Cassette mec (SCCmec) och används som en markör för MRSA medan nuc och Sa442 anger S. aureus. PCR-positiva isolat odlas ut på agarplattor …
classification, resistance mechanisms, risk factors and clonal distribution
… cell wall. Methicillin-resistance in S. pseudintemedius is encoded by the mecA gene, that expresses modified PBP, named PBP2a or PBP2?, with a lower affinity for beta-lactams. The mecA gene is located on the staphylococcal chromosomal cassette, a mobile genetic element. In …
… Oxacillin resistant colonies where indirectly tested for the presence of the mecA gene with latexagglutination and this is used to confirm it as a MRSP. Among the 23 dogs that where sampled, almost 86 % where still positive within one to five months time. After six to thirteen …
… and methicillin. The gene that gives resistance characteristic of MRSA is the mecA-gene. MRSA strains are spread in both hospitals and in the community, and it is important to identify these bacteria with rapid and sensitive methods. In this study, Taq Man RT-qPCR was compared …
indikatorbakterier E. coli & Enterococcus spp samt Staphylococcus spp isolerade från hud
… Staphylococci with high degree of resistance were tested for presence of mecA-gene by PCR. Results: Looking at the whole material there were no difference in antimicrobial resistance compared with food-producing animals. No difference in resistance regarding age could be …
… världen över. Resistensen utvecklas genom att stafylokocker erhåller en gen, mecA, som ändrar ?-laktamantibiotikas målstruktur. Idag är MRSA-utbrott vanligt i många länder, men hittills har vi i Sverige inte konstaterat mer än 20 fall på häst. Risken för att fler fall kommer att …
