Staphylococcus aureus finns naturligt bland annat på huden, i näsan samt i sår hos människor och djur. Därför kan bakterien överföras till mat som bearbetas med händerna. Bakterien kan orsaka magsjuka om den får tillfälle att föröka sig och bilda gift i livsmedel, men för detta måste temperaturen vara högre än normal kylskåpstemperatur Bakterien Staphylococcus aureus, den gula stafylokocken, finns ofta på människans hud (nagelbanden) och nässlemhinna och kan lätt hamna i mat under tillagning. Bakterien kan tillväxa och bilda sitt toxin om livsmedlet förvaras vid olämplig temperatur för länge Staphylococcus aureus is a Gram-positive, round-shaped bacterium that is a member of the Firmicutes, and it is a usual member of the microbiota of the body, frequently found in the upper respiratory tract and on the skin.It is often positive for catalase and nitrate reduction and is a facultative anaerobe that can grow without the need for oxygen How long do Staphylococcus Aureus infections take to incubate? Since S.Aureus bacteria is already present in your system, it does not take much time to incubate and start showing symptoms. However, if you are infected through contagion, Staphylococcus Aureus usually takes about four to ten days to start showing symptoms Staphylococcus aureus tillhör människans normala flora av bakterier. De flesta barn och vuxna är periodvis bärare av dessa bakterier, vanligen i näsan, men även på andra slemhinnor och på huden. Staphylococcus aureus är också den vanligaste orsaken till variga sårinfektioner eller bölder
Staphylococcus aureus is a type of bacteria. It stains Gram positive and is non-moving small round shaped or non-motile cocci. It is found in grape-like (staphylo-) clusters. This is why it is. Staphylococcus aureus, (græsk: stafylé = drue) også kaldet gule stafylokokker, er en ubevægelig Gram-positiv bakterie som findes på hud og slimhinder (næse, mund, underliv etc). Den er årsag til alvorlige sygdomme som 'tamponsyge' (formelt toksisk shock syndrom, TSS) og hospitalsinfektioner.Sygdomme, der hyppigt forårsages af S. aureus er furunkler, karbunkler og andre hudinfektioner Omkring 50% av den vuxna friska befolkningen är tidvis bärare av den gula stafylokocken (Staphylococcus aureus), vanligtvis i näsa. Oftast rör det sig om ett tillfälligt (så kallat intermittent) bärarskap, men cirka 20% är ständiga bärare i näsan Stafylokocker (Staphylococcus) är ett bakteriesläkte med cirka 50 arter där flertalet arter aeroba alternativt fakultativt anaeroba, icke sporbildande grampositiva runda bakterier ().Namnet Staphylococcus härrör från grekiskans staphylé som betyder druvklase, vilket syftar på bakteriernas utseende i mikroskop. De producerar på ett par undantag när katalas, vilket gör att de lätt.
